Thank you! I have learned so much from you. You and Mr Pete are the best teachers on TH-cam.
Good stuff Joe! Back when moldmakers used rotary cross slides, I was taught to find the center of rotation by placing a magnet base and indicator on the turntable and then indicate a pin held in the spindle. This method produces the true center of rotation, as opposed to relying on the accuracy of the center hole which may be obscured by a cross slide or fixture plate. An easy way to save time (and a lot of cranking) is to disengage the worm gear and spin the turntable by hand for this operation.
Thats a great tip, ill probably do that going forward!
I'll show that in an upcoming video. It does establish true rotation if the hole is out. Excellent comment.
Hi Joe,
I sincerely appreciate your taking the time to explain the nuances of degrees, minutes, and seconds. I haven't worked with these measurement units since school so the refresher is appreciated!
Nice shot of the dial, thank you for taking the time to set it up. It made your explanation very good.
In just a few seconds you hammered the reason I built a small shop to do machining. Having done software and related engineering/science pursuits most of my life - much of which becomes ephemeral pretty quick (and no one would believe you or care if you told them your stuff was making their phone work), I felt a need to have some things I could point to and say "I did that". Even if no one else cares, I still do. Bingo.
You get it.
Joe....having spent 40 years as an engraver and now doing machining....i find your vids very interesting and informative.....keep up the good work
I lost count of how many useful details you squeezed into this one, great job Joe, I'm really looking forward to the rest of this series!
Joe, I found your channel by accident and am glad I did. I am a gunsmith , and when I went to school for it ,we did have a class for machining of course. But, there were things we were not taught . You have broadened my knowledge that I can use to do more custom work and also to make and improve tools. Thank you for sharing your experience.
Joe, you are the ONE-STOP-SHOP for all things machining info! Thank you so much for sharing your knowledge with us that are still learning the ins and outs of proper machining!
Glad to help
Haha! I just went from "Yeah, yeah, I already know how to use a rotary table and I don't have no time to watch no video today" to "Oh! So THAT's how the seconds calculation works!" (that I had never bothered to really understand); and then to "Oh yeah, so THAT must be why the radius of that part was mysteriously slightly larger than it should've been!" (when I had never thought about the need to re-establish the radius over the zero between a linear cut and a radius cut. Just like you show, if you don't, your "new" radius of tool edge to part center is related to the length of the hypotenuse of a triangle whose adjacent side is the radius you 'want' and whose opposite side is the radius of the endmill. You really could do the trig and see *exactly* how many mils you'd be off if you forget). Thanks for another great video that has (once again) made me slightly less dumb. :-)
Loved the close view of the dial/graduations - very helpful 🍺
Very Informative video Joe very clear and to the point.
I'm kind of old school, I like using the rotary table as much as I can or when I can, this way it will keep your mind thinking
I use an advanced cross slide rotary table, so I can unusually do some unusual stuff on a mill.
Yes, a CNC is faster, but like I said I'm old school .
I usually put the rotary table's center at 0,0 on the DRO's Absolute, and the normal X,Y movements on Incremental, this way you can always jump right back to the center of the rotary whenever you need to.
Sorry for the long-winded message
Machining has been a passion of mine for years, and once I get started I have a tough time stopping.
I absolutely love how your videos are some out of the box straight forward solutions to problems I may not have encountered yet. Thanks so much.
I have one as a hobbyist, used on my mill drill. You certainly have cleared up some of the features and use of the rotary table.
Excellent video Joe! I love it that you get down into maths side of these things. Your excellent description of the degree, mins & seconds made it all clear to me. Thank you.
Plywood? That stuff is more expensive than steel now lol! Thanks for the video! I'll definitely be waiting a lot more if they are like this.
Great video Joe. Would have messed up the first part without the, (keep the center line) lesson. As always thanks for your great teachings. You are making many of us better machinist.
This is all new to me and something I have always wanted to learn more about, starting with the basics thank you Joe.
Our rotary table project in Machine Tool Technologies at the local college was a 5-sided fire hydrant wrench. A great exercise in making the outside of the wrench with the larger circle around the pentagon meeting the tapered handle to a smaller radius on that end. Cutting the 5 straight sides on the inside was a lesson in remembering backlash and locking everything down for each edge.
I think your rotary would suit me just fine! All I have is a beat up old one.
This is all good stuff Joe - thanks for doing it. :)
Thanks, Joe. Nice camera mount at the end and really looking forward to your next installment.
Cheers, Gary
I'm looking forward to getting stuck into to this series with you Joe on Rotary Tables.
Joe thank you so much for these videos. I have the same rotary table and it’s really confusing for an old grunt. I’ve learned so much from you. Thank you again!
Thanks Joe, I'm grateful for the information you provide on your channel. Great content, well presented and easy to understand. All the best for 2020!
BRASS CANON..... yeah we know , we only been waiting 2 years . :))) I Just bought myself a rotary table so I will be watching these videos with eagerness. Thanks.
The wheels are 14 spoke 7 segment assemblies. Intricate.
Awesome bonus content! I made almost exactly the same thing to use as a shield when using flood coolant to grind bores. I used an old mag base for the base and a sheet of plexiglass for the shield. Keep up the good work 👍🏼
As usual, outstanding video Joe. I’ve got a 6in Vertex horizontal/vertical rotary table I purchased to fixture a couple angle plates to, mount a frame between the plates, and checker 1911 front straps with eventually. I ran into some problems during the setup. Been stuck there since. This series should be a huge help. Looking forward to keeping up with it. Very good info! Thanks
I believe I'll offer up a few things to reduce the stress. thanks for watching.
Great video. I have just bought a rotary table and I'm cutting change gears for my lathe. I really appreciate learning more about the table. Thanks heaps.
Excellent video, and explanation! Recently I was victim off climb milling, and broke a carbide end mail, damaged the part, and need to re-trim the head! Thank you Joe! This videos will help a lot to me and others!
This Dude is a absolute genius! I learn so much from him. Thanks Joe!
I always sincerely appreciate the work that Joe Pie does on these videos. I always learn from his teaching sessions, and I sincerely appreciate his hard work that result in these video's.
My sincere thanks and appreciation, Scott
Thanks Scott.
As a new hobby machinist, I found your video very informative,
I new nothing about the minutes and seconds and how to read them,
so thank your for making a clear and understanding video of the rotary table.
Glad you enjoyed it!
Great stuff, i grabbed one of these when i purchased my lathe/mill combo, even though i had never seen one let alone used or even understand how its used but i saw the potential.I knew i needed it for one specific job (a radiused slot in a motor mount for mates RC car) so just grabbed one, i made sure to get one with the indexing plates as well, making it more versatile still,not that i have even come close to understanding everything it can do but this video sure helped me get closer,even something as simple as mounting(more complicated on a combo machine like mine without a full milling table,only the lathe crosslide,i don't have room 2 machines at this time and most of my milling work very tiny parts anyway,i only wish i could have both my vice and table mounted concurrently) it is now a bit clearer TYVM
Fantastic, Joe, you are an inspiration! And you are the reason I have a laptop next to my mill/lathe! Well done! Stan, UK
Thanks Joe. Very good explanation for a rotary table. I am surprised I have never heard one word on this before. As always great hanging out with you.
I just recently got a rotary table and just stumbled onto this video so it was very interesting to me thanks again you are my go to youtube channel for machining info before I check any others out
Awesome! Thank you!
Home machinist and always had trouble with my rotary table . Now I understand what I was doing wrong . Great video give use more and thanks for keeping simple for us self learners
Joe Pie... knocking it out of the park... year after year!
Fantastic info, Sir! I love all your videos, keep 'em coming⚡
Great stuff Joe, always enjoy your "no nonsense" explanations. Best wishes from the UK.
Fantastic Joe, thank you very much. This is just the instruction I want. I am looking forward to further videos. Best wishes. Andy
Awesome content. The locating of parts onto the rotary table will be very helpful, as I haven't seen any one else make a multi part series just on this topic. Thanks.
Joe, thank you for video. I am looking forward to this series of videos. I have only used my table in the flat position on the mill but would love to see some information about using it in the vertical position.
Excellent, can't wait for the rest of the series. My table is usually mounted with a spare 4 jaw chuck which I find most useful, making it very quick to mount up many parts. Loved the add-on video at the end!
Me too. No more tripod for general video work.
Thank you for the video Joe. That is the same 125# table I am using. I bought the Phase II at work 20 yrs. ago. Someone apparently dropped it off of the milling machine table and rendered it useless. I brought it home, took it apart to find slight damage to the worm and main spindle. Cleaned them up on the lathe and had to buy new table locks and oil sight glass to get it back in working order. Works fine once again.
Thank you Joe.
You are an excellent teacher.
@joepieczynski great explanation of the degrees,minutes, seconds. I understand it now . thanx
Thanks Joe looking forward to next Video on rotary table;
recently using my 6" rotary table, cut a very tight spline,
with 36 splines (16mm round) using a Lathe threading bar in the mill.
worked great (Part: Lawn Mower trans axle).
Very good info, i just had a yuasa 10” tilting rotary table and a 8” Hartford super spacer with a three jaw and all the index plates given to me, looking forward to using them, thanks again for the info
Joe, Thanks for the clear explanations. I am looking forward to the rest of this series and am eagerly waiting for the tangent cutting episode. :D
Joe, thank you so much for going these videos! I have learned so much, these are all things i have always wanted to learn to do probably.
Fabulous video. I always....always learn something new on every one. Loved the bonus material. Keep 'em coming.
Great video, thank you. As someone with a rotary table who hasn't yet come to understand how to properly use it, I appreciated this video.
There are a few more coming. Thanks for watching.
Thanks so much for this very timely vid. Please continue with more RT 101. Your thorough and meticulous explanations are dead on. I REALLY would like to see how to do multiple curves. I have a piece of plywood picked out for the "homework". This is what makes things stick for me. I have almost exactly the same RT and have used it a couple of times but I'm going to be much more confident after this.
Outstanding. You will like the next few secrets I share. Stick around.
You demonstrated and spoke, I learned. Thank you very much.
Got more coming. It gets better.
Love your Playland, Rye, NY sign! I grew up near there. Good video. Can also be used in a CNC lesson on how to use G40, G41, G42.
Thank you! Another great post. The rotary table is a great tool to have. They often go for very cheap at machinery auctions as the CNC machines have made them obsolete. I once got a job in a great machine shop because a shop foreman saw a part I made on my motorcycle using a notary table.
Very timely, I need a rotary table for a job I’ve committed to have done by the end of the month. I wouldn’t have thought to look for the zero orientation. I hope I can find one with the tee slots in the perpendicular orientation.
Thanks for yet another awesome tutorial.
They may have done that so you can use the vertical real estate for pins and screws in a fixture plate ???
Great video and great lesson Joe! I like that Go Pro camera mount too.
Super interesting stuff Joe! Can't wait for the next video to see this in action. Nice new toy at the end.👍👍
Awesome. I ove that you explain the theory behind this stuff and why you need to do things a certain way. Can;t wait for the next installment. Thanks for putting out these videos.
I cannot believe I have only just discovered this channel. Fantastic !
Thanks. I hoped I earned a subscription.
Absolutely
Very cool Joe very intuitive. I still remember the first time I used a rotary table many many years ago, all I can say is them was some fun time's
I just started my homeshop to do machining rather than just fabbing. You help me with your knowledge sir, thank you, I'm trying ...and seeing all the tricks given whilst you make chips drives me even more, if i could only borrow your brain for a while lol , but thank you Joe
Very informative, thanks. I look forward to more rotary table vids. A rt is on my want list.
my first operation (attempt) on a rotary table was to cut a hex in the end of a round to hold a die....I put a fine point marker in the quill to and drew out the design to prove my setup/moves.....great educational video and looking forward for more.....
Hi Chuck. Thanks for stopping by. This series will go for a few, and I hope show some very time saving techniques. Stay tuned and rub Howie on the head for me.
Awesome vid. Am looking at buying my first rotary table and mill drill in my workshop.
Love your videos! If possible I would give them all my 10 thumbs up.
I plan to build a shop hoist (A-frame) to lift things like this onto the mill so I don't hurt myself or drop and damage these expensive things. The vice and materials can easily get too heavy to safely lift. Likewise with larger lathe chucks and bigger shafts. I'm not getting any younger. Looking forward to the next vids.
Not as much fun but I suspect a commercial hydraulic engine hoist would be cheaper and will fold up for storage.
Barry Gerbracht None of us are. If you figure that out, let us know:) All I did was make/fab/weld up a tool cart for the heavier stuff and lower the table of the mill to height and lock the wheels and slide it over. Teflon or any kind of high density plastic works great. I have a hydraulic hoist to lift the heavier stuff onto the table. Obviously It needs to be not top heavy. I have the lower shelves with enough items to keep it in check. It obviously can then be rolled out of the way and allow more room for work space that’s non confining.
Looking forward to seeing this series Joe.
Watching this again today, I had not noticed your comment about having the slots align perpendicular when zero'd. I had the same issue with mine, I just added another zero indicator in the right place for that. Actually its good for all sorts of setups, like odd clamping, picking up on features, etc.
I made an extension to re position my pointer. I wonder if they offset it for a specific reason?
Yeah thats what I thought, every single one I have ever seen is offset, just have not figured out why.
Joe, master machinist awesomeness. You keep sharing the most amazing information and detail. Thank you.... thank you..... thank you. 👍 😁
Thanks man.you just keep dropping little gems for helping me remember/understand
Thanks for watching.
Thank you Joe. I appreciate your sharing
Always good to see old school. Thanks!
Thank you for all your videos and the time you put in to explanation.
Greetings from Sweden
Thanks for checking in.
Joe you are a excellent teacher !! Thank you Mark from MN
Good info! Now slap an xy table on top of the rotary and compound it. I did some of that years ago, a real head scratcher!
Another great video. I have the basics of the rotary down, but looking forward to your more advanced series of vids. Thanks and keep up the great work
I have a few things to show that will rock your world. Stick around.
Timing is perfect Joe , I need to make a flywheel for my model Hot Air Engine. Now if I can just pay enough attention to get it right the first time. Looking forward to the next one , Thank You 😊!
As always Joe. Thanks. Great work as always. Thanks for the video on the tooling ball. Bought one and will be working on a specific project soon that made me go holy crap. It works better than sweeping the hole. Keep up everything. Wish I lived in Austin.
Awesome channel, really appreciate the knowledge
Thank you for these videos Joe! Really do appriecate dropping the knowledge lile this.
Monday I start my new job as a
machinist teacher.Definitly will
recommend your videos to the
students.
Thank you. feel free to suggest topics.
HI JOE, THANKS SO VERY, VERY MUCH FOR THIS ADVICE , YOU ARE AN EXCELLENT TEACHER !!!! I AM A HOBBIEST AND THIS IS GREAT INFO. I DO NOT HAVE A DRO ON MY MILL AND SHOWING THE WAY TO ZERO OUT IS FANTASTIC !!! THANKS SO VERY MUCH JOE OUT IN JERSEY.
I lived in Morris county for 37 years. Great state.
Thanks for your videos... You have taught me a lot of cool tricks...
This is a very timely series for me--I just bought one (I thought I'd get one before the tariffs bump the price up) and I haven't had a project for it yet. I signed up for notifications and will be waiting for the next installment with great anticipation!
Thanks, Joe, great video!
Very fine. Thanks. A thought occured in regard to the slots positioning. A new zero point could be referenced/marked reflecting the desired. It's basically arbitarily situated (unless I missed something - I haven't reflected, just a quick thanks as I will get one of these and took a look at your work. The 3ft camera gave excellent shots and you must be happy with that. Have a joyful continuance.)))
Hey Joe, really enjoy your videos. My comment is about your suggestion of the t-slots being oriented in a certain position while at "0". I have an 8" Phase II, and the handwheel can be disengaged from the table, allowing it to freewheel. Then can be re-engaged at "almost" any orientation. (Unlock the table, then swing the lever that's between the handwheel and table to disengage, now rotate the entire handwheel assembly, until it disengages from the table. The pinion is on an eccentric, rotating one direction will disengage, and the other direction engages. Now the table can freewheel into any orientation.)
That takes care of the slot issue, but then the index marks and pointer are out of line. I made an offset extender for the pointer and solved the problem. I show it in one of the other rotary videos. thanks for the suggestion.
@@joepie221 I was thinking about this as a solution to the conundrum when you pointed this out and that was my thoughts, move the reference mark so it is Zero when the slots are aligned. You did that already, best solution and problem solved.
Cheers from John, Australia.
PS Enjoy the Bash.
Yo, Joe!... I had the same concern [6:00 mark] ie; slots not aligned with the axis of the table.
It bugged me so much, I re-located the pointer. Now I smile!
Thx again for your content.
I moved mine too.
Excellent, thank you. Looking forward to the next vid.
Great stuff Joe, many thanks. Can't wait for the next instalment...
Great teaching. Thanks
Great video as usual Joe. Looking forward to future video's on the Rotary Table, particularly one that might be related to putting parts on and centering them to the table... This is one area that for some reason, I've always struggled with (i.e., accurately locate an existing part that needs a round radius feature so that the origin of the feature is at the center of the rotary table). This is especially true for parts that do NOT have a feature already at the center origin of the new needed feature
Correct. Nobody seems to be willing to go there. No feature to pickup....Not a problem. Stick around.
Thank you, I’ve been waiting for a video on a rotary table. Great JOB can’t wait for the next one.
Can't wait for part 2. Great job!
As always great video !!! I enjoy the info as I have 2 rotary tables and I find them very useful..
Saw a recent post on Facebook for a rotary table storage cart. Make cart u shaped so can fit around end of mill table. Crank mill table to the left, roll cart around end of mill table. Align height of mill table with height of cart, slide rotary table on or off mill table.
Great idea. These things are heavy.
Steven Haskell Did that 25 years ago. Nothing is worth injuring yourself or damaging machinery.
Indicate the flat edge, then turn your slots until they line up on x axis and put your own marker where ever the 0 is. Try to indicate the slots and get that zero mark where it is convenient for you. Just like those pcs of tape, but mark it permanently or drill and tap a hole directly under the zero, and move that adjustable marker to that position.
I hope I said it right, or I’d have to draw pics. I enjoy your teaching and work. I started machining in the early 70’s like you. My expertise is mainly milling on large horizontal boring mills, huge planer type mills, and jig bore machines, and larger lathes. I did start in some small shops on Bridgeport’s and lathes too. Keep on teaching my friend, I do learn some nice tidbits here and there.
I made a new offset index plate. Problem solved.
