Well done Dave! I've had thoughts for a long time, attaching a stepper motor to the rotating table and an Arduino to do the stepping. 90 turns per rev originally multiplied by 200, 400 or 800 gives a resolution of 1 per 18000, 36000 or 72000. It ought to manage most things. All gear is sitting around... Thanks for the inspiration Dave!
@@TheMiniMachineShop Maybe Clough42.... I know about his electronic leadscrew. Got a home made bolt circle calculator based on an Arduino UNO, and it works! Made all the stuff for an electrical leadscrew but not used it yet...
Hello Dave, Great work, can you please point me in the direction of the video where you made your Milling Vice jaws. I am interested to understand the sticking up parts on top of the jaws. Thanks Paul,,
Hi Paul, Simple, I added the four brass pins so I can quickly clamp mainly round material over using V blocks. Both pulleys sat flat and were well secured while I drilled and reamed them using the pins. Also, it's a 3" vise so with V blocks I can't clamp 3" material. No room but can with the pins. Also 3" square material can be clamped.
@@TheMiniMachineShop Thanks Dave, I have a 3" vice that I am fixing up for my mill and will do the same... When I show it on UA-cam I will make sure everyone knows it was your idea.
Hi, I've seen that done before but it leaves a round bottom which causes the belt to ride up resulting in belt wear. But how are you going to do it without an expensive rotary table and cutter.
@@TheMiniMachineShop I thought the HTD belt teeth had a round profile when compressed, GT2 has more clearance. Once I filed the burrs smooth, the belt seemed to fit perfectly.
>how are you going to do it without an expensive rotary table and cutter. PCD function in a DRO allows radial drilling of holes, if that's what you're asking.
@@TheMiniMachineShop I understand what a timing pulley/belt is, I build engines and the timing pulley on engines is used to rotate the cam at the right timing.
Great job Dave nice work
Glad you enjoyed it

Gloug42? spelling did it and is offering code and more.

Way to go Dave. I have thought about making one of those so maybe you have inspired me.
Go for it!
GREAT JOB DAVE, GOOD TO SEE YOU DOING MORE VIDEOS, KIMBER
Hi Kimber, hope all is well!
Coming along nicely.
Thanks Steven!
Gday, nice job mate, Cheers
Thank you! Cheers!
Good morning Dave, where did you get the dividing head setup? I have been looking for one in that size for my mini mill.
It came with the rotary table, but I think it's sold separately www.amazon.com/gp/product/B082BLRQ22/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Nice job
Thank you! Cheers!
Hi Dave, Where did you get or how did you make the cutting bit for this?
I made the cutter HSS on my D bit grinder.
I've attempted to make timing gears another way. Indicate on chuck and then drill holes using the DRO PCD function, then turn down on lathe to finish.

@@HM-Projects Sorry I was only thinking of the square belt I'm using which isn't round. In your case that is an excellent way to make a pulley.
well done!
That was one long haul to get here...
Otra vez te admiro , saludos
What is this pulley timing?
It's a special pulley that a timing belt rides on with teeth so it can't slip.

i do love a good magnifying myself!
