All I can say is thank you. The drill press is one of my favorite tools. Thanks for the demo and the story on those changable pulleys. I always marvel at such things, and the minds that create them! And now I know what a ladder chain is too. Thank you!
What a great drill press and an even better price. I'm still using my Dad's old 1937 Sears Companion, bench top drill press. Still works remarkably well. Thanks for sharing.
Thanks for the video. I have this same model of drill press and really love it. Mine has an 1140 rpm motor, which brings the speed down to around 300 rpm. FWIW, I paid about the same as you did for mine. Original receipt on mine says it sold for $265 in 1964, so you got a great deal.
I envy you the room you have for all those tools. I have a small table-top drill press because It's all that will fit in my garage. The idea of having three or four stationary tools of different types never occurred to me.
Glad folks could point you to a chain supplier, I am sure chain was selected over a belt to keep the pointer synchronized properly. Thanks for all the great lessons sir!
Thanks for showing us how that works Mr. Pete! A very well built machine indeed. I have an old Polaris quad that uses that variable speed transmission, it's automatic so it just adjusts itself with your speed.
Sweet looking press and an excellent find for the price as most of the import drill presses are junk. Please keep up the good work as you are a true mechanical Genius and a wonderful gift to us in the field who want to improve our machining & shop skills. Best Bill B
Over here, in the UK, we had the Raglan lathes from the early '40s until '71 (bought out by Myford and closed down). A different adjustment mechanism, but the same variable sheave pulleys. Great little lathes and a small milling machine (I have both) with the same drive. ChrisB257 even took lathe his with him when he moved to your side of the pond. For the Raglans they recommended always starting on low speed to help the motor a bit; not so important for a simple drill spindle (no heavy chuck, lead screw gear train and possibly a heavy workpiece in the chuck!). Your drill looks like a super example of a quality product built at a time when durability was still in the vocabulary.
Very nice machine! I always love the variable pitch pulley systems. I had a go cart with an 8 HP Briggs & Stratton engine using them. It would go nearly 70 MPH!
I really like the single-handle as it is adjustable and seemingly quite quickly as well. That old drill press looks great and I would venture to say that was a pretty good deal!
Thanks for the video, and all videos for that matter but this one helps me especially because I have the same model with a broken chain also and kind people have given the links to find it. Nice piece of machinery also.
2 Thumbs up!!!! mrpete!!! I am really glad to see that you made this video on the drill press, reason being is I bought one last summer that is the same as the one you have in your basement the man was selling 3 of them all Delta Rockwell .The one I bought was said to have bad bearings and or bad motor ( the spindle was froze up TIGHT, motor would not turn) the other two sold very quick one $280 the other $350 I paid (bid) & won mine for $80 thinking it would be a good rebuild & learning project (maybe?) & I would finally have a good name brand floor model drill press. When I made it home & started to check to out (take it ALL APART) because I know NOTHING about Delta/Rock drill press's it wasn't the bearings or motor at all but that NUT just above the chuck the one that you put the chuck key handle into(spanner nut?)was so tight that it locked down the spindle & motor!! I cleaned & oiled, greased everything that turned & put it all back together everything worked, ran GREAT until that nut ran itself up tight again & stopped it dead! Could you or maybe one of your many wonderful subscribers know why this keeps happening? I don't think anything is missing. I went online looked up the model # (15-555) found a parts list but that didn't really tell me anything also what is the JT size?( I think it is a # 1) I need to buy a chuck for it & don't want to buy the wrong taper. I really hope someone can tell me what I am doing wrong because its driving me nutz to have it just sitting there and waiting. I would love to finish cleaning, painting this NICE Drill press and FINALLY start using it' Sorry this became a short story but I wanted to get it all out there lol. And like always GREAT JOB Mrpete you Sir have taught me so much and I Thank You!
Rosario W I am glad you found the problem with your machine. What if you removed that nut? I guess it was meant to help remove the chuck but it might not be needed. Or drill, tap and put a set screw in the nut to prevent it moving up the spindle.
AtelierDBurgoyne Thank you for the input it is much appreciated , yeah that seems to be the only use I can see (or remember) for that nut to be there is to push the chuck off instead of using wedges. I never thought of a set screw I might try that
If it's the same chuck as Mr. Pete's, I believe it's a JT 33 taper and the chuck is a Jacobs 34. I bought a chinese version without the threaded collar and made a nut for it. Same thing happened to me as you. I'm gonna put a little set screw in it with a brass insert to keep from marring the threads. I have a Sears drill press and a Clausing that use this exact chuck. www.mscdirect.com/industrialtools/jacobs-34-33c-keyed-drill-chuck.html Good luck!!
Others may have mentioned down-thread, but I think the spindle down-feed lever is the high end item. If you are running multiple parts, you can adjust the lever to exactly where you want it. And you can set the lever so it won't be running into a larger work piece...it beats having to remove one of the down-feed levers because it's interfering with the work.
I just found your channel, really enjoy. I have just bought a Delta rockwell model 15 650 VS . Mine looks just like yours . Mine also also came with a 3/4 3 ph 115 volt. I'm sure I will have some questions as I get into it. I have heard you mention Springfield , and Branson, I live in Bella Vista AR so we are probably not to far apart. Lol
Matter of personal preference, I find the adjustable single handle to be "best". Throw and geometry can be tailored to the work you are doing. Good find, great price.
Thanks for passing on more of your seemingly infinite knowledge! I never fail to learn something interesting and valuable from your videos. I was wondering about how the variable speed worked on these drill presses. Thanks for explaining what the 15 inch means also. I just bought a 17-600 Rockwell, and I was wondering about what the 17 measurement referred to.
We used to have a commercial mixer we used for mixing cake mix and dough for Croissants. The mixer was a Russian made Bear varimixer which used an identical variable belt drive. I wonder if the Soviets had a spy steal the variable drive design from Rockwell? ( ha ha ) As for Car trans ,the most well known belt drive was the Dutch DAF ,which was later redesigned and sold as the Volvo 360 .
My dad had the Volvo DAF 66 auto car that ran this variable speed transmition, the odd quark about it was that it would go as fast in reverse as in forward, made the lower sphincter tigthen if you pressed a little too hard on the accelrator when in reverse lol. Nice video @mrpete222 I much prefer the older drill presses that why I purchased and restored an Atlas 64 / 74 not sure which
TC You mentioned you might have paid to much for this machine. I would have paid more. Been looking for one for a long time in that good of shape. Ever change your mind I’m not far away from you .serious! Take er off your hands. Thanks to someone who has become a friend I’ve never met.
I own the other failed Delta split-pulley variable speed drill press (20-950). You're lucky to have found this. It's absolutely fabulous to not to mess around with belts to change speeds. To your point, its complexity prices it out of reach for most people, and it wasn't a commercial success. Mine is early-days Chinese (Delta trying to keep the price down), so execution is disappointing in some ways. Still with a bit of rework it's a marvelous addition to the shop. Powermatic makes one now, but it's an inferior design to the Delta.
There was a dreadful little car made in the Netherlands, (the DAF), that used pretty much the same variable cone pulley system as a transmission. It used engine vacuum and springs to automatically change ratios dependent on load and speed.
Great video, just what I need as I soldier through refurbishing mine which was fished out a dumpster in remarkably good shape! Any suggestions for a replacement belt? The one I purchased on ebay is about 3/4" too long yet has the correct part number.
I have a Clausing Drill Press from about the same era and its cone drive is not as well designed and made as this one seems to be with the possible exception of the indicator mechanism. The cone drives in the current import presses that I have looked at are very flimsy and will not last very long IMO. It does not surprise me that drill presses are going to electronic speed control with inverters as I am sure they are cheaper to manufacture. Enjoy the "new" addition to your shop!
That Cain is used for many things. I have seen it as pull chains. I think my local supply store has a big spool of that chain. If you can give me the width that might help me know if it will work
I have the same exact model, I got it last week on offerup for $850. I think I paid a lot for it but it looks flawless and near mint, unrestored. I’m hunting down a model 20 now for some heavy use
Mr. Pete, did you find out a source for the little chain that drives the speed indicator? If not, I think I have info on what it is and who makes it. Let me know. Wade in Huntington Beach, CA. It is called ladder chain.
Hey Mr Pete, greetings from Northern Illinois! I was wondering about the key slots on the base of the drill press. Do you know what that feature was meant for?
Nice video Mr Pete. The chain and sprocket looks just like Meccano kit to me. A question though. Was there a mechanism to adjust the belt tension similar to step pulley drive?
I believe that single handle was put on by a previous owner. I own one of these drill presses and it has the standard 3 handles on the quill feed. Which is also what is pictured in the Owner's Manual
I think I have the part you are looking for. I upgraded a similar drill press to VFD some time ago The diameter of my sprocket is : 0.939" ; overall length of shaft is 1.355" with a turned down collar of 0.372". Chain length (doubled over ) is 5.125" and width is 0.26" You're welcome to both as I have no need for them
Question, I have the same drill press model Delta Rockwell 15-000 but the regular pulley system. What is the brass little nob for on the left hand side? Next to the id tag.
I got one of these 25 years ago, worked great. Suddenly the spindle would stop turning under a load. Took the cover off and watched the system through speed changes. At the lowest speed, the motor-end pulley would open too far leaving the belt loose against the pulley spindle. Then noticed two missing set screws on the motor-end pulley. Raising or lowering the pulley spindle on the motor shaft caused crazy variations in the reported drill press RPM readout. It didn't take much to find the correct location (and secure it with set screws). But I haven't quite figured out how someone setting this machine up would know the correct elevation of the motor-end pulley and what the elevation is relative to. The answer may come to me in my sleep (as answers do). Still, if anyone can tell me, I would appreciate it. Yeah, lifting that table and securing was tolerable for a long time, but at 76, I'm not liking it. I'm thinking hydraulic cylinder.
@@mrpete222 Whether or not I understand why, the variable speed is working and a 4" hole saw won't stop the spindle. I only just found you based on the one video. That is quite an anthology you have on youtube---great resource. Not being able to pick things up is a shock. Let a vintage 1 foot jointer with 7 foot table go last summer because I can't throw a 2 x 8 x 12 beech plank up on it anymore. Riding a bike 10 miles doesn't faze me. I can dig the garden for the wife. I play the piano a lot with no issues----helps my arthritis too. Guess I'll have to accept what aging leaves me with, but I don't like it. Best to you.
Replacing the chain with a new piece is the easiest fix. If I were to replace it with a rubber belt, I'd spring for a cogged timing belt and two pulleys with the teeth milled in them, to keep the indicator arm in the same relative orientation just as the chain does, i.e. "c locked" or "timed".
I have a delta 15-270 in really good shape but the spring doesn't return the arm, it doesn't appear broke and i'm not sure how to adjust it. Wondering if you have any idea's? these are the part numbers for what it looks like. Pinion spring cover #402-04-031-5001 , and pinion spring assembly #402-04-320-5001.
Oh look it has a CVT (Constantly Variable Transmission) LOL. Never turn that dial when the drill press isn't running, you'll really screw up that variable speed mechanism. Hey, it even says that right on the front. Same way with the Shopsmiths, those things really got messed up if you turned the speed adjustment dial without the machine running. The CVT's in vehicles use chains rather than belts if I recall.
Attempting to restore an older Delta 15" bench style drill press in need of new bearings; since New Departure no longer exists can anyone suggest an alternate source for what are most likely Chinese counterparts?
The variable speed drive is called a Reeves drive en.wikipedia.org/wiki/Continuously_variable_transmission#Variable-diameter_pulley_.28VDP.29_or_Reeves_drive My variable speed Series 1 Bridgeport mill uses the same type of drive as does my Ariens(/Husqvarna/Gravely - same mfg.) "automatic" lawn tractor. CVT transmission cars use a segmented metal "belt" running in a special "traction oil" instead of a rubber/fabric belt. CVT car transmissions are not repairable yet to my knowledge except by the manufacturer. They are simply replaced with a new one if it breaks $$$$$.
I think he meant that the sprockets are misaligned, not in the same plane, and the ladder chain gives it enough slop. It wasn't completely clear to me.
The only problem I can see about using a pulley and belt is....that if you go too far, or it slips, the meter may keep moving, and the needle will be off. That's probably why they used chain in the manufacture. I can't think right off the name of the belt, but it's flat with notches. Cars use them a lot, like on water pumps and timing belts. I haven't seen any chain like that in a long time, but someone may have some out there.
I"ve seen that variable drive in one of Gardner Hiscox'es books, I think this one books.google.com/books/about/1800_Mechanical_Movements.html?id=o__li03lqBQC Very neat set of books and it's quite amazing how we keep re-inventing the wheel...
Jimmy Stewartism: "We got a rack and pinion here is what we got." It isn't so much the voice quality as the mannerism and word usage, but yeah, you sound like Jimmy Stewart.
Hi Lyle, That appears to be very similar to a chain that used to be supplied for a chain drive in the Meccano setwww.meccanospares.com/sprockets-and-chains.html YoursAllister
safety hazzard the head casting just clamps on the tubular post vibration can cause it to drop-slide down the post in use. drill a hole thru the casting and tube and install a safety bolt.
Legitimate question here...has anyone actually seen this happen? Clausing, for one, also clamped the heads to the column. My 20” has a safety collar, but properly tightened, the clamp bolts exert tremendous force. I can’t imagine them coming loose.
What a load of twaddle! I would think every pillar drill ever made uses this build method. The table is fixed by this method on many drills and unless you loosen them they don’t slide down. Here in the UK 90% of builders scaffolding is built by collars clamped onto tubes and they don’t slide into a heap when a bus drives past! I’ll give you a 14lb hammer and you see if you can move the head down the tubular post by hitting it. News-flash! -you won’t move it. Do you have a seat-belt on your arm-chair?
470 RPM is just too fast as the lowest speed, why don't machine tool designers make machines that go down to 40 RPM with powerful motors and gear drives? I know such machines exist but they're all massive industrial machines when smaller versions are possible to make for home shops.
I have 2 drill presses a bench top and a floor model. They both turn way faster than I like for 1/2 inch and larger drills. So I use the mill for that. Have thought about swapping in a lower rpm motor though.
Thankyou Mr Pete for another informative video. I sort of knew the theory on the variable speed mechanism but it was great to see it i action.
Thanks for watching
Nice machine Mr Pete! Glad to see some viewers led you to where to buy that broken chain.

Hey Mr Pete, greetings from Northern Illinois! I was wondering about the key slots on the base of the drill press. Do you know what that feature was meant for?
Also, to hold large work. The table is swung off to the side, and the drill press head may or may not need to be lowered
What a beautiful old press. How about trading for my clausing. 20inch? I’m getting too old to move the beast
I am too old to move the one I have
Thanks for the information sir.
Nice video Mr Pete. The chain and sprocket looks just like Meccano kit to me.
A question though. Was there a mechanism to adjust the belt tension similar to step pulley drive?
That was cool. Thanks!
I get small drive chains and sprockets at local belt and bearing store
What is the proper way to set belt tension on this press. I just picked one up and the belt seems loose through all speed ranges
I wonder how difficult it would be to convert a modern drill press to that cvs drive?maybe an assembly from a go cart or something
What type of Chuck do these drill presses have is it a tapered Chuck that can be removed with wedges?
Have you tried a bicycle chain?

yes--I just ordered chain--ebay
I got one of these 25 years ago, worked great. Suddenly the spindle would stop turning under a load. Took the cover off and watched the system through speed changes. At the lowest speed, the motor-end pulley would open too far leaving the belt loose against the pulley spindle. Then noticed two missing set screws on the motor-end pulley. Raising or lowering the pulley spindle on the motor shaft caused crazy variations in the reported drill press RPM readout. It didn't take much to find the correct location (and secure it with set screws). But I haven't quite figured out how someone setting this machine up would know the correct elevation of the motor-end pulley and what the elevation is relative to. The answer may come to me in my sleep (as answers do). Still, if anyone can tell me, I would appreciate it.
Yeah, lifting that table and securing was tolerable for a long time, but at 76, I'm not liking it. I'm thinking hydraulic cylinder.
Thank you for the comment. I’m afraid I can’t help you, I have not had any trouble with mine. At 78, I can’t lift anything anymore
@@mrpete222 Whether or not I understand why, the variable speed is working and a 4" hole saw won't stop the spindle. I only just found you based on the one video. That is quite an anthology you have on youtube---great resource.
Not being able to pick things up is a shock. Let a vintage 1 foot jointer with 7 foot table go last summer because I can't throw a 2 x 8 x 12 beech plank up on it anymore. Riding a bike 10 miles doesn't faze me. I can dig the garden for the wife. I play the piano a lot with no issues----helps my arthritis too. Guess I'll have to accept what aging leaves me with, but I don't like it. Best to you.
Replacing the chain with a new piece is the easiest fix. If I were to replace it with a rubber belt, I'd spring for a cogged timing belt and two pulleys with the teeth milled in them, to keep the indicator arm in the same relative orientation just as the chain does, i.e. "c locked" or "timed".
yes--I just ordered chain--ebay
I have a delta 15-270 in really good shape but the spring doesn't return the arm, it doesn't appear broke and i'm not sure how to adjust it. Wondering if you have any idea's? these are the part numbers for what it looks like. Pinion spring cover #402-04-031-5001 , and pinion spring assembly #402-04-320-5001.
Would you show us how the other press works
Looks like meccano chain. Probably a bit bigger though
Thanks for watching
Nice find Mr. Pete, if you need the chain my friend will sell it for $190.00.
Thanks for watching--lol
👍👍👍👍👍
Oh look it has a CVT (Constantly Variable Transmission) LOL. Never turn that dial when the drill press isn't running, you'll really screw up that variable speed mechanism. Hey, it even says that right on the front. Same way with the Shopsmiths, those things really got messed up if you turned the speed adjustment dial without the machine running.
The CVT's in vehicles use chains rather than belts if I recall.
Thanks for watching
William,
What would happen if one did attempt to change speeds while not operating?
Thanks,
ian
It jams or pinches the belt
Oh yes, I see how that would happen. Thanks.
Continuously Variable Transmission. A constantly variable transmission would be of little practical use ;-)
MR. PETE, GO ON E-BAY LOOK UNDER DOEPKE TOYS, SOME OF TOYS I BELIEVE , USED THAT CHAIN. GOOD LUCK JOE.
Thanks for watching
How come that other drill press makes more noise?
Don't know
Attempting to restore an older Delta 15" bench style drill press in need of new bearings; since New Departure no longer exists can anyone suggest an alternate source for what are most likely Chinese counterparts?
Any bearing house will have replacements
The variable speed drive is called a Reeves drive en.wikipedia.org/wiki/Continuously_variable_transmission#Variable-diameter_pulley_.28VDP.29_or_Reeves_drive
My variable speed Series 1 Bridgeport mill uses the same type of drive as does my Ariens(/Husqvarna/Gravely - same mfg.) "automatic" lawn tractor.
CVT transmission cars use a segmented metal "belt" running in a special "traction oil" instead of a rubber/fabric belt. CVT car transmissions are not repairable yet to my knowledge except by the manufacturer. They are simply replaced with a new one if it breaks $$$$$.
Never saw one with four handles.
Why not use .25 pitch sprockets and chain from McMaster Carr
I think he meant that the sprockets are misaligned, not in the same plane, and the ladder chain gives it enough slop. It wasn't completely clear to me.
The only problem I can see about using a pulley and belt is....that if you go too far, or it slips, the meter may keep moving, and the needle will be off. That's probably why they used chain in the manufacture. I can't think right off the name of the belt, but it's flat with notches. Cars use them a lot, like on water pumps and timing belts. I haven't seen any chain like that in a long time, but someone may have some out there.
I can't take chuck off my delta 12 it's a table don't know how
What kind of spindle is it?
I"ve seen that variable drive in one of Gardner Hiscox'es books, I think this one books.google.com/books/about/1800_Mechanical_Movements.html?id=o__li03lqBQC Very neat set of books and it's quite amazing how we keep re-inventing the wheel...
The part # for the chain is 402-04-023-5001
Thanks
Jimmy Stewartism: "We got a rack and pinion here is what we got." It isn't so much the voice quality as the mannerism and word usage, but yeah, you sound like Jimmy Stewart.
I would just replace the indicator with a digital tachometer. 10 to 25 on amazon.
use some stainless wire and repair that chain. you can lace a belt. you can lace a chain!
DAF made from 1958 cars with cvt transmission even long after the plant was sold in 1975 to volvo.
Thanks for watching
Hi Lyle, That appears to be very similar to a chain that used to be supplied for a chain drive in the Meccano setwww.meccanospares.com/sprockets-and-chains.html YoursAllister

player pianos use chain like that. contact player piano company, wichita, kansas
safety hazzard the head casting just clamps on the tubular post vibration can cause it to drop-slide down the post in use. drill a hole thru the casting and tube and install a safety bolt.
Legitimate question here...has anyone actually seen this happen? Clausing, for one, also clamped the heads to the column. My 20” has a safety collar, but properly tightened, the clamp bolts exert tremendous force. I can’t imagine them coming loose.
What a load of twaddle! I would think every pillar drill ever made uses this build method. The table is fixed by this method on many drills and unless you loosen them they don’t slide down. Here in the UK 90% of builders scaffolding is built by collars clamped onto tubes and they don’t slide into a heap when a bus drives past! I’ll give you a 14lb hammer and you see if you can move the head down the tubular post by hitting it. News-flash! -you won’t move it. Do you have a seat-belt on your arm-chair?
I lost the tip of my left index finger when changing a drill bit and the head dropped.
Type erector set chain into ebay.
that is chain is from mecano
Thanks for watching
Not infinitely variable, just continuously variable
true
470 RPM is just too fast as the lowest speed, why don't machine tool designers make machines that go down to 40 RPM with powerful motors and gear drives? I know such machines exist but they're all massive industrial machines when smaller versions are possible to make for home shops.
Lite Roadie Why would you need 40 RPM on a machine that is designed for drilling the smaller range of hole sizes?
I could not agree more. Even a slow speed motor on this machine would give 300 rpm
I have 2 drill presses a bench top and a floor model. They both turn way faster than I like for 1/2 inch and larger drills. So I use the mill for that. Have thought about swapping in a lower rpm motor though.
