Thanks for the compliments chaps, now it is up to me to get the best out of it, I am sure it is going to help me a lot in the future.

Ralph,

1.5" (about 38mm) diameter drill. But you've got to remember, I have the power to turn one at very low speed.

I did some fine tuning this morning, I adjusted the worm to wheel, there is a small grub screw on the casting that allows you to set it spot on and repeatable. It now runs like silk with no grumbling tight spots, and still no backlash. I will set all the ramp up/down and running speeds when I come to use it in anger, plus I have to learn all about those things first, before fiddling with the settings.

I also took the opportunity to modify and fit a small folding handle handwheel on there, just in case I still want to use it in rough manual mode.

If you decide to fit a handle for any reason, one thing you MUST DO FIRST is UNPLUG the motor from the DivMaster before turning it, as under certain circumstances you can turn the stepper into a genny, and you don't want power feeding back to all those electronics.

I'm sure I will do other little twiddle twaddle bits to it, like cable clamps etc, but now, mechanically wise, this is definitely finished.

Indeed! Damn huge bit as far as I'm concerned! I'd have been boring it out from about 25mm (largest slot drill) Still would have got a similar result though, just a lot slower :)

Looks good with that handle on now John :thumbup: I went looking for similar but found nothing.... I'll look again next week.

Now awaiting the first results of the testing on a workpiece :dremel:

Ralph,
It came from RDG, but not the normal site, this small size isn't listed on there, but from their shop on eblay.

I got a couple of these Ralpf they work well nice and strong but take up little room and fold as it's supprising how strong a stepper of that size is.

Tried the e-bay shop John as that's what you said when we were discussing the one you have there... Nothing listed?

But got that link from Peter that should do the job just as well :thumbup:
I'll go measure the spindle on my machine and see what I can do about the old "handle in the wrong place :bugeye: " issue ::)

Ralph.
