Brilliant idea, and brilliantly executed. I was pondering how to mount a small four jaw chuck onto my very small rotary table. Ha ha, I now know. Many thanks to you and Adam for this excellent design.
Hello from Chicago {suburbs} Andrew. I came across your channel by accident. Yours is one of over 50 channels to which i subscribe. I especially like your narratives and camera work. Nice job. I will be watching for your on-going videos.
Hi Andrew, I have reduced the time taken with the powered cross feed for facing :) As standard geared cross feed, which is 6.61mm (off the radius) a minute at a spindle speed of 450 rpm. Over 7.5 minutes for a 50mm radius !!. With the motorised leadscrew, I'm now able to do 11.53mm a minute, saving a good 3 minutes. When facing a 100mm diameter part, (50mm radius divided by 11.53mm = 4.3 minutes) I still have independent control of the spindle speed, to control for the larger diameter work pieces. Adam
Hi Adam - you have definitely designed and built an excellent modification for the SC4 lathe. I'm sure others will have a go at making one. I wish I had the time. I'm going through a patch of everything breaking around me and my machining projects have stalled at the moment. All the best. Andrew
Andrew, it seems you've forgotten the link to your zip file? I have a need to attach a small 4 jaw chuck to my six-inch rotary table so this project is perfect for my need. It was really great of Dave to write a comprehensive manual for the TouchDRO software. He illuminates some of the more esoteric functions of the program. Thanks for making this video, very helpful!
Hi George - Lotus beat me to it! Glad you found the link OK. If the diameter of your 4 jaw chuck is significantly smaller than your rotary table it might be worth changing the design and putting the T-bolt holes on the outside edge. Take care mate. Cheers Andrew
Hi - personally I think that a 3 inch table is too small. The tee slots will be very limited in length, reducing work holding options. You would not be able to hold a 100mm chuck on it either. My 4 inch table is just big enough to hold a 100mm chuck using the adaptor I made. Regarding 3 or 4 jaw chuck - it all depends on what you are planning on doing with it. If you just want to hold items centred in the chuck, then I think a 3 jaw self centring would be the easiest option. However, if you want to offset a piece, then a 4 jaw independent chuck would be the way to go. I hope that helps. Cheers Andrew
Thanks for Your interesting videos. I made a comment, likely to another of Your videos, talking about Arduinos reading iGaging magnetic scales. You answered and You are interested. Somehow I've lost the link to our conversation. I've got hold of a well written, advanced code that I think I'll manage to use and develope. However, I ran into another difficulty. Can You send me a personal message, favourably an Email, in order to move on?

New here, nice to come join you while you are making things come along. Lance & Patrick.
Excellent

I think Andrews put the link on the other videos since this one's more of a separate project video, haven't checked tho
@@JackT9595 thanks I'll check!
I went back to video number 4 of the TouchDRO series and found the link, thanks again!

I have a Amadeal XJ12-300 mini mill and i`m considering a 3 inch rotary table, which would you recommend a 3 or 4 jaw chuck ?

@@learningturningmetal Thanks for the info. My mill table is only 1100mm deep thats why I thought about a 3" rotary.
@@learningturningmetal thamks Andrew ive sent for a 4 inch table and chuck. Happy bunny
Good job Andrew,
My rotary table is the one from Arceurotrade which has four tee slots.
ATB Adam
Thanks Adam - I quite fancied an Arc one when I was looking. They look really good, but a little above my budget :-(
Cheers
Andrew
@@learningturningmetal
Wow, the price has shot up !
I got the 4" table and indexing set for about £150, many years ago.

What is the mechanism on the SC4 lathe that looks like a carriage stop?
Hi Brandon - yes it's a carriage stop I made in video #MT26. Check out this link:

All the best.
Andrew
you can zoom in on that screen by placing 2 fingers on screen and spread them apart. you can zoom so close you dont even need to look at the numbers
Wow - many thanks for the tip. The TouchDRO is absolutely brilliant! I've obviously got lots to learn.
Cheers
Andrew
