Don't be ashamed of your hands Mr. Pete. Your hands tell the story of a thousand projects. They are the hands of a master craftsman and have the muscle memory to work every operation as if by magic. They are your hands and they have built your life. I would love to hold my fathers wrinkly old gnarled hands one more time and somebody will feel the same about yours some day.
Please do a follow up. I found this fascinating. I have watched almost all your videos. As is usual most entertaining. Thank you. All the best to you and your family.
Lyle, I agree to asking for a follow-up to see the Pull-Gear in operation. I'd love to find one, even if a hammer & chisel (H&C) mechanic worked on it like happened to yours. I bet the H&C mechanic damaged it before the Internet got started well and he had no idea how to take it apart. You were able to ask for help, while the H&C mechanic couldn't do more than asking coworkers or friends who didn't know either.
Don’t get frustrated and what you’re doing there is a lot of us out here that truly enjoy what you’re teaching us and the things that we can learn off of each other is indispensable. Keep up the great work on the videos keep them coming.
Thanks Mr Pete. keep going with the application of the unit. It would be a "must see" for all who have followed the videos.Best wishes, your 71 year old student.
I have been a mechanic for 27 years and fully understand most of what you are talking about and STILL find it interesting! After watching some of your videos I cut apart a torque converter one day! I knew how it worked but never had seen inside one! Thanks for the effort Mr Pete!
Thank you for watching. Funny you should mention that. I had planned on cutting a torque converter open. But it would be a messy job, and I don't think anyone would care to watch it
Thank you very much for taking the time to show this. There were several of these types of devices used when I worked in machine shops, but I never actually ran a drill press. I did see them in use for 3/4 and larger drills. Some of the machines used a thin metal "cowling" around these to keep the oil that was slung out some what controlled and the operators had to oil them every 2 - 3 holes. :)
thanx for the series.there's a lot of forgotten knowledge from our past history. i loved it when you showed the slide scale. wars were won with the calculations made with those. kids nowdays would be lost if they had to calculate with that or run a manual machine for that matter.
I am surprised that you did not make the pulley group and show how to do it! I worked for a Cat dealer where our machinist would take and re-groove pulleys to clean them up! Cat heard what he did and came out to see the process, realized that as long as there was spring tension on the belts you could take and re-groove the pulley, you took off the top of it the amount it took to clean up the grove wear! Long story short, Cat went back and wrote a special instruction magazine on how to do it and how much to take off!! Thanks Paul, you had a great idea! Loved the look on the engineer's face, as Paul was showing him how to do it!!
I thoroughly enjoyed this series. Thanks Mr. Pete. Great job as usual. Loved the slide rule ! I studied electrical engineering in college and everything from multiplication to logs and trig functions were done with a slide rule. I still remember the 6' slide rule hanging over the blackboard that the instructors used to demonstrate the calculations. Boy do I miss those days. Thanks for the memories.
Really enjoyed, what a nice way to slow down a drill press! I took a. Planetary gear set out of a junk 12v winch, poured a new housing and machined it to fit on an 4" auger we use in our small business, still working! Also found in screw guns, reduction gear motors of all kinds! What a wonderful mechanism !
This was a very interesting series, I love the detail of how it works, the good humor, and yes I love the distractions, especially the bicycle "who cares?" Grinning as I type this.
This was a great series. I have an old British sports car with a 28% reduction electric overdrive with very similar inner workings. Once again a great series
Mister Peterson, remarkable stuff! You ALWAYS amaze me, with what you can do. I remember my father's 2 foot long slide rule, with REAL ivory on it. I also remember him buying a calculator, 4 function, for WELL over $200. 40 years later, you can find them, at the "dollar store." steve
Sounds like another slide rule bites the dust! We can only imagine since you spared us the carnage! :-) I truly enjoyed this series, as I do all of your videos. You are indeed a treasure to us. Thanks, Mr. Pete! :-)
Would first like to say, I enjoy all the little details. I'm a maintenance technician but with no scholastic based training, The majority of what I have learned to do my job is from those around me, and going through all kinds of different videos about a huge variety of things that have given a great host of insight into things that so many take for granted. I know that filming so much can be very taxing and I can understand if you don't have the notion to film so many details. But don't ever feel that viewers don't care as so many of us do, but just are the quiet majority that don't comment as much as the Negative Nancies. And as my personal 2 cents. If you have heated up the lower sheave section before final assembly, (there were no bearings in that piece at the time ) then would have most likely been able to install both bearings much easier. Though my only experience to speak from is vicariously through watching your videos. So very possible I am not seeing something you had already accounted for. Thank you for all your hard work on your videos, Mr. Pete. God Bless you Sir.
Thank you for watching. I have done much much maintenance over the years. I think a maintenance man has to have a much wider knowledge of electricity and mechanicsthen many of the other trades.
Thanks Mr. Pete! Enjoy every minute of all your video, and the cut away ones are most informative! Love to see it in the press and working with larger bits. With proper tension on the belts I can't see them slipping unless the bit catches breaking through but usually the bit will spin in the chuck first...1-800-Bad-Chuck. Just please be careful if that piece lets go on the sheave.
Another great series of videos Mr Pete. Thank you for posting them. I really liked the part where you used the Plexiglas to show the gear train in operation.
Thank You for doing this very interesting project. I have followed it from the beginning and your explanation of planetary gear systems was very well put. Incidentally, when I was growing up in England, in the 1950s, my first bicycle had a "Sturmey Armchair" 3 speed hub gear just like the one you showed, but of course I never knew how it worked, (it just did!).
Mr. Pete, Thank you so much for doing this project. It was very educational. I am eagerly awaiting the installation on one of your drill presses. Gary 75-Year-Old Home-Shop-Machinist In North West Arkansas
Thanks mr pete do a follow-up video on it running on the drill press appreciate ur time and effort u put in the video's u make ur dad must have been a fine man to have had such a hard working son
Thank you, Mr. Pete. Enjoyable as always. I remember seeing these once, while traveling in my Popular Mechanics "Time Machine." I'm eternally grateful that, my Father started that collection. Anyway, I seem to remember reading that, the unit worked similarly, to a lathe back gear. I can kind of see, what they were getting at. In fact, the unit seems a lot like the epicyclic back gear assembly found on the Craftsman "109" lathes. I could be totally wrong, though. I'd love to see the unit installed and running on a drill press.
We like the long projects :) I would have liked to have seen you go all the way with it and have the welding repairs done on it since you had it all apart anyway, but I understand why you didn't. Great series. Thanks for all the hard work putting the videos up for all of us.
Thanks MrPete222 for making this video! I have pondered building a similar gear reduction for my own drill press, but was unaware that such a product existed commercially at some point. It seems that placing the reduction on the driven shaft would be a better solution, since that would reduce the load on the belt instead of increasing it.
Another great video series thankyou for all your effort there will always be people that knock anothers efforts your videos are both entertaining and educational
I agree, if you dont find it interesting click on something else. Negative comments serve no purpose. It makes me think what would have happened if I has a teacher like Mr Pete in my day. Long may he continue,
Excellent video, very interesting. Your see through set-up for the planetary gear function was very informative in actual motion. A picture really is worth a 1000 words. There is low temp aluminum rod out there that would allow you to fill and repair the pulley sheaves...used with propane and surprisingly strong and easy to use. Probably demos on TH-cam.
Great video series. Funny thing though after watching this series I came across a functional 4:10:1 in the throw away pile at work. The owner had a small machine shop. Not sure why it was discarded because it’s in really nice condition. Seems to work just fine but it was outside. Plan on tearing it apart and making sure there are no gremlins in there. Would’ve never known what it was till I watched your videos. Thanks for doin what you do Mr Peterson.
A very excellent, informative series...I like the old school use of your slide rule instead of the calculator. In 1975, I bought a Texas Instruments calculator for $250 with a red lit display. I had buyers remorse -- too much 💰. Soon afterward, the price dropped considerably. I still keep my old slide rules for backup -- you never know if radiation (EMP) will fry all PNP/NPN junctions leaving all electronics useless...☠️
If you mounted the whole unit in the lathe and cut a small groove where the upper and lower half meet you could stretch an undersized I ring over the gap to seal it up so it won't sling oil. I would also use wheel bearing grease in it instead of oil. That's probably why it's worn out. I was thinking I could make a new one in 3 weeks if I had to. Fascinating project. Thanks
Mr. Pete222 I have build many cnc spindles any where 500 to 190,000 rpms from wood working to metal cutting. I think you bilt that just fine. Job well done.
Always good to see the full thinking on every item , many times it gives a perspective that might not be seen by many! Oh in hyd, log loaders, those gear box's when mounted, where referred to as grizzly box's , but I think that was just due to the manufacture name on the box LOL ! They where just reduction box's with up to 6 idler gears on the ring gear, no speed change for the 360 rotation , the engineers misjudged the weight a few times, on diff size loaders after blowing a couple on test pad, we had to change out many the first few weeks of testing ! Thanks for the great work on videos !
I've really enjoyed this one ... Can't explain why but It's been a lot of fun to watch. And some how better for being fixed and not rebuilt (although I'm going to call in and see what that option looks like too).
Hi Lyle maybe chain saw bar oil would be the best lubricant for your gear reduction pulley. I use it on my atlas lathe gearbox because it clings to the gears better without excessive oil slinging. Chainsaw bar oil would work great for your bicycle chain also for the same reason.
Funny that you mentioned your hands just as I was thinking about them. I was actually admiring them and thinking that I liked the look of hands that do stuff. My own hands are about 10 years younger than yours but well on their way to being "doing stuff" hands.
Mr Pete love your videos. You used to install the first bearing. I was hoping you would use cold to install the other bearings. Place the bearings in a freezer for an hour or 2. Thanks again for all your videos.
Excellent series. I would have considered some grease on the gears, but that’s just me thinking to myself. I’ve always enjoyed the How DoesIt Work videos. Just so you know. Keep it up.
Hey Mr. Pete: The reactive member can be any of the members: Sun, carrier (planetaries) or ring, depending on the direction requried and gear reduction. It refers to the held member. The carrier is actually the biggest gear in the set, and you can use the sum of sun and ring gear teeth to give a value for the planetary gears. If the sun is input and the ring is held, you get maximum reduction (smallest drives largest gear) Sun is input and carrier is held - reduction in reverse through the ring gear Ring is input and sun is held - "medium" reduction - medium gear drives largest gear Ring is input and carrier is held - overdrive reverse - medium gear drives smallest gear Carrier is input and sun is held - overdrive in forward Carrier is input and ring is held - greater overdrive in forward Now, since the pin is on the plate that is basically the planetary carrier, holding that provides reduction between sun and ring, in reverse. Idlers allow, as you said, the ring to run in the same direction as sun. Tying any two members together provides direct drive. Hope that doesn't muddle up too many folks!
Thanks, Mr. Pete... fun series. Some sort of shroud around that thing would at least stop the oil from slinging out everywhere. Maybe even with a felt lining to catch the drip... or just a felt ring retained by elastic. Can you tell I'm "inventing" as I type? Also, a similar first-hand experience tells me that JB Weld epoxy would work as a filler patch for those hunks out of the pulley edges. Might reduce the belt wear.
Lyle, I think when it comes time to run this on the drill press with even a small amount of oil in it, you'll conclude it's time for that "O" ring seal I mentioned earlier. The oil that slings out is bound to get onto the belt and run down onto the drive pulley when the motor is off making the belt traction problem even worse. Of course running with no oil will grind the gears into dust . Not trying to be a doomsayer here, but just being practical. And it's still not too late to fit an O ring by just using a triangle file to break the sharp edge while rotating it in the lathe like you did earlier to study the unit in operation, but file the groove with it in direct drive of course. Hopefully those 4 screw heads will cut OK with the file since they are now so close to the surface. But it wouldn't take much of a chamfer to hold the ring centered. Using the small .062 section ring of 5.125" OD it should stay centered over the gap and should be very forgiving of any run out between the discs, unlike conventional face type seals. And, like I said earlier, it's inexpensive and no disassembly is required to install a new O ring seal when it wears out. Seems to me this is certainly worth giving a try. The .0625" section "O" rings (AS568-049) can be had thru Mcmaster.com as stock number 9452K314 for $6.40 per pack of 10. These should be about right if the housing is about 5.125" diameter. Adjust size as needed though to suit your housing. It should slip on and make a snug fit. A heavy synthetic differental lube might be best. Plain GL-5 would work but stinks way too much because of the EP additives. If any leaks out it would smell up your entire basement. Might even experiment first using plain 30W non-detergent motor oil available at Walmart for about $2.50 /qt. Also, you might want to drill and tap a second hole for the reaction rod 180 degrees from the other one for balance purposes, and as a side benefit, the threads in the holes will last twice as long since there are now two of them. Good luck on this project. Ray Satorius
Thank you Ray. But I cannot be worried about that. I have already moved on to many more projects. And that gearbox will be removed in the next video and be replaced by a direct current motor. Thank you for the suggestion
Lyle, The DC motor probably won't be much of a torque solution. The brush type DC motors are voltage controlled and lowering the voltage also lowers the current reducing torque and speed. With the VFD controlled AC motor the torque is close to 100% at slower frequencies below 60Hz although the power (hp) is reduced in like proportion below 60 Hz. A good graphic layout of the typical VFD can be seen here: www.pumpsandsystems.com/topics/pumps/motor-horsepower-torque-versus-vfd-frequency Actually a quick calculation of the torque of a 1725 rpm 1/2 hp. motor is only about 1.52 ft./lbs. which is nothing breathtaking, and you can stall this with your hand. So if you need more torque than this, then it will be necessary to use a larger hp motor, like 1 hp which would give about 3.0 ft./lb. etc. between stall and 1750 rpm. Of course if you can live with constant speed lower rpm motor, you can get the same 3.0 ft./lb. by only using a 1/2 hp motor which normally runs at 875 rpm. But they do cost a little more but might save the cost and complexity of a geared drive. With the 875 motor the output is being "geared down" electromagnetically by using more poles rather than having to use a mechanical transmission, like a Pull Gear unit. It also has the benefits of not having anything to wear out or lubricate as well as being very quiet. Ray Satorius
I am very disappointed to hear that. But I will be going ahead with experimenting videos with thesese DC motors (3/4 hp) on both the drill & bandsaw. I have already used vfd s & been disappointed in them too.
Please by all means show it all squared away on the drill press. It was really fun to see epicyclic gearset complete with idler,put together in a very 1950s gadget. Well done with the puzzling through how to properly disassemble,tinker and tweak,and reassemble. Cheers.
Mr Pete, this was interesting indeed. Maybe its drawback was that necessary gap in the design let it throw out all the oli and run those old open bearings dry causing it to fail. If this was myne, I would assembled it with the gears smeared in boat bearing grease(blue colour) and remove one of the oilers and replace it with a grease nipple, or just a screw that can be removed to add/inject more grease, I am sure that will dumb the bearing sound right down. If it then ejects grease(I suspect not as much as oil), one could make a cover to catch it and reuse it somewhere on the tractor. I used this boat bearing grease to silence my small drillpress spindle, seeing it does not have multiple splines like the large one I got, so oiling it makes it noisy. I think the only way to stop this design from spilling, it to enclose it like a diff, but then you loose the compactness of the pulley on one half of it. Maybe somebody can come up with a nonspilling design although it will take up more space, or will that then rather result in a small compact gearbox-?
In a way I kind of hated to see it go back together after so much went into taking it apart :P I would have chamfered the face of the pully to clean it up but like you say, you've had enough of it. Hope to see it in action in the future. Thanks for the video.
That was explained well, the place that I am most familiar with planetary gear arrangement is with automatic transmissions. As for a seal to control the oil sling I suggest a strip of leather in the top section in a grove cut just inside the outer diameter just like it was used in earlier times.
your tenacity is rewarding. hope it works for you. I went so far as to purchase off ebay 3 speed lawnmower small gearbox after a bit grabbed my piece and pummeled me arm. Still sitting under counter. gave drill press away. If it does sling, close slot with a silicon caulk(easy to remove).
Hi Lyle I would love to see it work. On the lathe it did not actually sound that noisy. Maybe the oil you added helped. The inner tube or big o-ring ideas both sound excellent. I would venture to say that a slice off of cheap 26 inch x 1.75" or so mountain bike tube would stretch just fine. Might even serve as a noise dampener too! :-) ps.-just a bit of trivia: I am am avid mountain biker. Terrain varies greatly from flats to very steep sections and obstacles like fallen logs to cross(which is part of the fun of course). Having lots of gear choices is an advantage. warm regards vic
I thought I heard the collective squall of engineering wannabees with empty slide rule holsters from past generations when the screen went dark, and *bang!* Maybe a wide rubber band to cover the gap? Thanks for the visual in the lathe. It made perfect sense. Thanks for doing it, even if it was a long project. I really enjoyed it.
Great series and the project came out great. Enjoyed. It would be a good improvement if they had 3 jack screw holes to separate the unit. Thanks for sharing.
Great vid. I remember as a kid discovering the 3speed planetary gears. Would seriously like to see it working if possible. I sure could use one on my old mill/drill. Keep up the good work.
Could cut a piece of inner tube to cover the gap to keep it from slinging oil. We would certainly like to see it run on the drill press. You would think with today's CNC technology those (or similar device) could be made at an affordable price. It would certainly help to use a drill press, instead of mill/lathe, to drill large holes. Great reassembly video. Very entertaining with my coffee. PS: I thought that looked like a nail.
A piece of inner tube stuck on to the top piece and hanging loose below with another one oriented opposite - overlapping it from below - might work to catch the oil and permit cleaning.
MrPete, I had the same problem with to higher speed, made up a boss off the stand shaft with bearings and a 3 row pulley upside down and then 2 shorter belts hi to low & low to high & hi to low had to reverse the chuck pulley, really only got a good low speed for large bits still a bit fast for 1 inch bits. Regards Frank
As a suggestion, try and get used to the phrase "that's not beaten up, that's patina!" Hot rodders would use the phrase to describe the condition of the unit. And yes, it would be perfectly acceptable to say that your hands have a nice patina as well. Very interesting series of videos. Thanks.
I've just been watching the pull gear rebuild , fantastic job ! I will be making one of these soon for my little band saw ! By the way , the ring gear has 65 teeth , planets 22 , sun 16 I think , all at 16 DP . Regards , Jim
The world-famous Sturmey-Archer epicyclic drive. It must have been used on millions of bicycles word-wide. There was another developed by Bendix here in the U.S. (S-A was a British firm) that was two-speed, and was shifted with a slight backward kick on the pedals. Schwinn offered them as an option at extra cost. Not nearly as good, in my opinion. You did a very nice job on this. Videos of this type make very interesting viewing. Thank you for your fine effort.
Don't be ashamed of your hands Mr. Pete. Your hands tell the story of a thousand projects. They are the hands of a master craftsman and have the muscle memory to work every operation as if by magic.

so very cool to see how these things work! i miss your other series, mr. pete - thank you for another great video!
Thank you
We like the long projects :) I would have liked to have seen you go all the way with it and have the welding repairs done on it since you had it all apart anyway, but I understand why you didn't. Great series. Thanks for all the hard work putting the videos up for all of us.
Thanks! Great series. That was a lot of work! I appreciate it.
Yes, it was a lot of work. Too much
Definitely need to see it running in the drill press! I will say it was much quieter than I thought it would be though. Very nice.
Thanks
Thanks MrPete222 for making this video! I have pondered building a similar gear reduction for my own drill press, but was unaware that such a product existed commercially at some point. It seems that placing the reduction on the driven shaft would be a better solution, since that would reduce the load on the belt instead of increasing it.
That's a good idea
Another great video series thankyou for all your effort there will always be people that knock anothers efforts your videos are both entertaining and educational
I agree, if you dont find it interesting click on something else. Negative comments serve no purpose. It makes me think what would have happened if I has a teacher like Mr Pete in my day. Long may he continue,
Thank you for your support
Excellent video, very interesting. Your see through set-up for the planetary gear function was very informative in actual motion. A picture really is worth a 1000 words. There is low temp aluminum rod out there that would allow you to fill and repair the pulley sheaves...used with propane and surprisingly strong and easy to use. Probably demos on TH-cam.
Thanks
Hello Mr. Pete,
I love your cut aways and wish to see more of them.
Be sure and watch all of the videos in my what makes it work series. Lots of cutaways
Very good series. Thanks for sharing.
Thanks
Great video series. Funny thing though after watching this series I came across a functional 4:10:1 in the throw away pile at work. The owner had a small machine shop. Not sure why it was discarded because it’s in really nice condition. Seems to work just fine but it was outside. Plan on tearing it apart and making sure there are no gremlins in there. Would’ve never known what it was till I watched your videos. Thanks for doin what you do Mr Peterson.
Wow, that was a good find. They are an awesome mechanism
G'day Kevin here from Australia. Another great series Mr Pete. A++ .
Thanks
Kevin Hamling ...tie me kangaroo down, sport- tie me kangaroo down...waltzing Matilda, waltzing Matilda...
I'd love to see at work on the drill press. Enjoyed the whole series. Thanks Mr. Pete!
You soon will
Awwww. I liked the what makes it works series !
Me too, but we don't count. :(
I had to discontinue that, nobody watched it
I did. :(
Fantastic plexiglass demo. Always the teacher except now more students.
lol
A very excellent, informative series...I like the old school use of your slide rule instead of the calculator. In 1975, I bought a Texas Instruments calculator for $250 with a red lit display. I had buyers remorse -- too much 💰. Soon afterward, the price dropped considerably. I still keep my old slide rules for backup -- you never know if radiation (EMP) will fry all PNP/NPN junctions leaving all electronics useless...☠️
Yes
The Anvil52 If an EMP happens- the loss of our calculators would be the LEAST of our worries!!!
The Anvil52 I paid $80.00 for my first digital calculator- and it didn't even have a floating decimal point-!!
Dale Burrell so true...back to the Stone Age...☠️
The Anvil52 YOU BETCHER LIFESAVERS!!!
That was a a fine rebuild and demonstration thank you Mr Pete. put a lot number on that unit I may want it later
lol
If you mounted the whole unit in the lathe and cut a small groove where the upper and lower half meet you could stretch an undersized I ring over the gap to seal it up so it won't sling oil. I would also use wheel bearing grease in it instead of oil. That's probably why it's worn out. I was thinking I could make a new one in 3 weeks if I had to. Fascinating project. Thanks
Yes
Gasket ring, and Sop it down with STP to quiet the planetary gears.
What about some heavier gear lube? I've had great luck with Lucas heavy duty oil stabilizer.
I have some of that
Just a great series Mr. Pete, appreciate your struggle. Got to be careful, don't get caught removing jewelry in the funeral parlor.
lol . He did have a nice ring that I was eyeing
I thought it might of been a she, and that you were trying to get your property back.
Mr. Pete222 I have build many cnc spindles any where 500 to 190,000 rpms from wood working to metal cutting. I think you bilt that just fine. Job well done.
Thanks
Always good to see the full thinking on every item , many times it gives a perspective that might not be seen by many! Oh in hyd, log loaders, those gear box's when mounted, where referred to as grizzly box's , but I think that was just due to the manufacture name on the box LOL ! They where just reduction box's with up to 6 idler gears on the ring gear, no speed change for the 360 rotation , the engineers misjudged the weight a few times, on diff size loaders after blowing a couple on test pad, we had to change out many the first few weeks of testing ! Thanks for the great work on videos !
Thanks
I've enjoyed the whole series. Thank you sir.
Thanks
I've really enjoyed this one ... Can't explain why but It's been a lot of fun to watch. And some how better for being fixed and not rebuilt (although I'm going to call in and see what that option looks like too).
Thanks
Hi Lyle maybe chain saw bar oil would be the best lubricant for your gear reduction pulley. I use it on my atlas lathe gearbox because it clings to the gears better without excessive oil slinging. Chainsaw bar oil would work great for your bicycle chain also for the same reason.
Thanks
well done! glad you stick with projects like this.
Thanks
Funny that you mentioned your hands just as I was thinking about them. I was actually admiring them and thinking that I liked the look of hands that do stuff. My own hands are about 10 years younger than yours but well on their way to being "doing stuff" hands.
Thank you, they are working hands. Not pretty, but very serviceable
Mr Pete love your videos. You used to install the first bearing. I was hoping you would use cold to install the other bearings. Place the bearings in a freezer for an hour or 2. Thanks again for all your videos.
Excellent series. I would have considered some grease on the gears, but that’s just me thinking to myself. I’ve always enjoyed the How DoesIt Work videos. Just so you know. Keep it up.
Thanks
Great video series Mr. Pete! Very interesting.
Thanks
Fascinating series, Sir. Thank you!
Thanks
Great video 👍🏼 I prefer the in-depth builds/repairs. Like my dad always told me-anything worth doing takes time
Thanks. Your dad was right
Hey Mr. Pete:
The reactive member can be any of the members: Sun, carrier (planetaries) or ring, depending on the direction requried and gear reduction. It refers to the held member.
The carrier is actually the biggest gear in the set, and you can use the sum of sun and ring gear teeth to give a value for the planetary gears.
If the sun is input and the ring is held, you get maximum reduction (smallest drives largest gear)
Sun is input and carrier is held - reduction in reverse through the ring gear
Ring is input and sun is held - "medium" reduction - medium gear drives largest gear
Ring is input and carrier is held - overdrive reverse - medium gear drives smallest gear
Carrier is input and sun is held - overdrive in forward
Carrier is input and ring is held - greater overdrive in forward
Now, since the pin is on the plate that is basically the planetary carrier, holding that provides reduction between sun and ring, in reverse. Idlers allow, as you said, the ring to run in the same direction as sun.
Tying any two members together provides direct drive.
Hope that doesn't muddle up too many folks!
Thank you for a great dissertation. But you are way beyond me
Thanks, Mr. Pete... fun series. Some sort of shroud around that thing would at least stop the oil from slinging out everywhere. Maybe even with a felt lining to catch the drip... or just a felt ring retained by elastic. Can you tell I'm "inventing" as I type? Also, a similar first-hand experience tells me that JB Weld epoxy would work as a filler patch for those hunks out of the pulley edges. Might reduce the belt wear.
Thank you very much
Lyle,
I think when it comes time to run this on the drill press with even a small amount of oil in it, you'll conclude it's time for that "O" ring seal I mentioned earlier. The oil that slings out is bound to get onto the belt and run down onto the drive pulley when the motor is off making the belt traction problem even worse. Of course running with no oil will grind the gears into dust . Not trying to be a doomsayer here, but just being practical. And it's still not too late to fit an O ring by just using a triangle file to break the sharp edge while rotating it in the lathe like you did earlier to study the unit in operation, but file the groove with it in direct drive of course. Hopefully those 4 screw heads will cut OK with the file since they are now so close to the surface. But it wouldn't take much of a chamfer to hold the ring centered. Using the small .062 section ring of 5.125" OD it should stay centered over the gap and should be very forgiving of any run out between the discs, unlike conventional face type seals.
And, like I said earlier, it's inexpensive and no disassembly is required to install a new O ring seal when it wears out. Seems to me this is certainly worth giving a try. The .0625" section "O" rings (AS568-049) can be had thru Mcmaster.com as stock number 9452K314 for $6.40 per pack of 10. These should be about right if the housing is about 5.125" diameter. Adjust size as needed though to suit your housing. It should slip on and make a snug fit.
A heavy synthetic differental lube might be best. Plain GL-5 would work but stinks way too much because of the EP additives. If any leaks out it would smell up your entire basement. Might even experiment first using plain 30W non-detergent motor oil available at Walmart for about $2.50 /qt.
Also, you might want to drill and tap a second hole for the reaction rod 180 degrees from the other one for balance purposes, and as a side benefit, the threads in the holes will last twice as long since there are now two of them. Good luck on this project.
Ray Satorius
Thank you Ray. But I cannot be worried about that. I have already moved on to many more projects. And that gearbox will be removed in the next video and be replaced by a direct current motor. Thank you for the suggestion
Lyle,
The DC motor probably won't be much of a torque solution. The brush type DC motors are voltage controlled and lowering the voltage also lowers the current reducing torque and speed. With the VFD controlled AC motor the torque is close to 100% at slower frequencies below 60Hz although the power (hp) is reduced in like proportion below 60 Hz. A good graphic layout of the typical VFD can be seen here:
www.pumpsandsystems.com/topics/pumps/motor-horsepower-torque-versus-vfd-frequency
Actually a quick calculation of the torque of a 1725 rpm 1/2 hp. motor is only about 1.52 ft./lbs. which is nothing breathtaking, and you can stall this with your hand. So if you need more torque than this, then it will be necessary to use a larger hp motor, like 1 hp which would give about 3.0 ft./lb. etc. between stall and 1750 rpm. Of course if you can live with constant speed lower rpm motor, you can get the same 3.0 ft./lb. by only using a 1/2 hp motor which normally runs at 875 rpm. But they do cost a little more but might save the cost and complexity of a geared drive. With the 875 motor the output is being "geared down" electromagnetically by using more poles rather than having to use a mechanical transmission, like a Pull Gear unit. It also has the benefits of not having anything to wear out or lubricate as well as being very quiet.
Ray Satorius
I am very disappointed to hear that. But I will be going ahead with experimenting videos with thesese DC motors (3/4 hp) on both the drill & bandsaw. I have already used vfd s & been disappointed in them too.
Can't wait to see it installed.
Coming soon
Please by all means show it all squared away on the drill press. It was really fun to see epicyclic gearset complete with idler,put together in a very 1950s gadget. Well done with the puzzling through how to properly disassemble,tinker and tweak,and reassemble. Cheers.
Yes
Mr Pete, this was interesting indeed. Maybe its drawback was that necessary gap in the design let it throw out all the oli and run those old open bearings dry causing it to fail.
If this was myne, I would assembled it with the gears smeared in boat bearing grease(blue colour) and remove one of the oilers and replace it with a grease nipple, or just a screw that can be removed to add/inject more grease, I am sure that will dumb the bearing sound right down. If it then ejects grease(I suspect not as much as oil), one could make a cover to catch it and reuse it somewhere on the tractor.
I used this boat bearing grease to silence my small drillpress spindle, seeing it does not have multiple splines like the large one I got, so oiling it makes it noisy.
I think the only way to stop this design from spilling, it to enclose it like a diff, but then you loose the compactness of the pulley on one half of it. Maybe somebody can come up with a nonspilling design although it will take up more space, or will that then rather result in a small compact gearbox-?
Yes
GREAT VIDEO MR. PETE, I LOVED IT !!! JOE
Thanks
In a way I kind of hated to see it go back together after so much went into taking it apart :P
I would have chamfered the face of the pully to clean it up but like you say, you've had enough of it. Hope to see it in action in the future. Thanks for the video.
Yes
I enjoyed every part , Glad to see it working again !
Thanks
That was explained well, the place that I am most familiar with planetary gear arrangement is with automatic transmissions. As for a seal to control the oil sling I suggest a strip of leather in the top section in a grove cut just inside the outer diameter just like it was used in earlier times.
Thanks
This was a great set of videos very interesting also i love the cutaways keep up the great videos!
Thanks
love your work. I am a bicyclist and a hobby machinist.
Thanks
Well done Mr Pete. Cheers
Thanks
excellent series, mrpete.
👌
your tenacity is rewarding. hope it works for you. I went so far as to purchase off ebay 3 speed lawnmower small gearbox after a bit grabbed my piece and pummeled me arm. Still sitting under counter. gave drill press away. If it does sling, close slot with a silicon caulk(easy to remove).
Thank you
Follow up would be very nice! Great job and nice visual aids! I would have enjoyed being in your shop classes. Thank you
Thanks
Hi Lyle
I would love to see it work. On the lathe it did not actually sound that noisy. Maybe the oil you added helped. The inner tube or big o-ring ideas both sound excellent. I would venture to say that a slice off of cheap 26 inch x 1.75" or so mountain bike tube would stretch just fine. Might even serve as a noise dampener too! :-)
ps.-just a bit of trivia: I am am avid mountain biker. Terrain varies greatly from flats to very steep sections and obstacles like fallen logs to cross(which is part of the fun of course). Having lots of gear choices is an advantage. warm regards vic
Thanks
I thought I heard the collective squall of engineering wannabees with empty slide rule holsters from past generations when the screen went dark, and *bang!*
Maybe a wide rubber band to cover the gap?
Thanks for the visual in the lathe. It made perfect sense. Thanks for doing it, even if it was a long project. I really enjoyed it.
Thanks
Great series and the project came out great. Enjoyed. It would be a good improvement if they had 3 jack screw holes to separate the unit. Thanks for sharing.
Yes, like Toyota used on their brake drums
Demonstrating with plexiglass was a great idea!
Thanks
Great vid. I remember as a kid discovering the 3speed planetary gears. Would seriously like to see it working if possible. I sure could use one on my old mill/drill. Keep up the good work.
Thanks
Could cut a piece of inner tube to cover the gap to keep it from slinging oil. We would certainly like to see it run on the drill press. You would think with today's CNC technology those (or similar device) could be made at an affordable price. It would certainly help to use a drill press, instead of mill/lathe, to drill large holes. Great reassembly video. Very entertaining with my coffee.
PS: I thought that looked like a nail.
I was thinking an O-ring stretched around it would be the ticket.
It would be hard to keep the inner tube on with one half turning and one half stationary, when engaged.
A piece of inner tube stuck on to the top piece and hanging loose below with another one oriented opposite - overlapping it from below - might work to catch the oil and permit cleaning.
You’re the best, Mr. Pete! I’m so happy that you chose to make videos for us all.
MrPete, I had the same problem with to higher speed, made up a boss off the stand shaft with bearings and a 3 row pulley upside down and then 2 shorter belts hi to low & low to high & hi to low had to reverse the chuck pulley, really only got a good low speed for large bits still a bit fast for 1 inch bits. Regards Frank
Thanks
It might have been a long project but I know i certainly enjoyed it. Thanks for the video.
I'm glad you liked it
As a suggestion, try and get used to the phrase "that's not beaten up, that's patina!" Hot rodders would use the phrase to describe the condition of the unit.
And yes, it would be perfectly acceptable to say that your hands have a nice patina as well.
Very interesting series of videos.
Thanks.
lol
Did the calculator get it with the hatchet?.... Thanks for sharing sir..
Almost
Very interesting and a great result.
All the best.
Andrew
Thanks
Excellent series, very interesting.
Greetings from Sweden
Thank you for watching. My grandfather came from Sweden
I've just been watching the pull gear rebuild , fantastic job ! I will be making one of these soon for my little band saw !
By the way , the ring gear has 65 teeth , planets 22 , sun 16 I think , all at 16 DP .
Regards , Jim
Thanks
The world-famous Sturmey-Archer epicyclic drive. It must have been used on millions of bicycles word-wide. There was another developed by Bendix here in the U.S. (S-A was a British firm) that was two-speed, and was shifted with a slight backward kick on the pedals. Schwinn offered them as an option at extra cost. Not nearly as good, in my opinion.
You did a very nice job on this. Videos of this type make very interesting viewing. Thank you for your fine effort.
Thank you very much
great series .. thanks for the videos
