How useful would a motorized turntable be for engraving with a vise mounted on top of it? Perhaps it would simplify do scroll work? I was thinking that I could make one with a DC motor, rheostat, and 9" metal platter.
Not very useful in my opinion, you might have soft areas and hard areas in the item your engraving thus your speed changes, I would stay away from that idea and learn to turn it by hand or feet as some have done
I'm not sure if I could use a motorized turntable, but I'd be willing to try it. The rate of my vise rotation varies slightly as I'm engraving, depending on material, resistance, whether it's curved or flat, etc. I'm not sure a constant speed would work. I don't know if Bryan Bridges' was variable or constant.
I've used gear motors, as you describe, DC and rheostat controlled. They've been smaller, in size, and the experience was NOT good. They sound like coffee grinders, with some gravel thrown in. When sitting at the bench, you don't need a rock crusher next to you. Perhaps there is a noiseless design out there, but I'm not familiar with it. In view of that, and until I see a super quiet gear motor design somewhere, I won't be making up anything any time soon. The variable speed units I've used are far from quiet.
Nope, it's just been that long since I was in Arizona last...
Like I said, there are a couple shotgun engravers that use them on a daily basis, and I think there's someone in the Southeast who does silverware on one.
They are out there. When I used one for a couple hours, it struck me that they would be great for production work.
And whatever motor was on Bryan's made little or no noise - nothing like a rock crusher.
It was a really slick, smooth setup.
When you see a lot of "stuff" and talk to enough people and add a little age into the equation - there are occasionally some leaks...

My theory is that when your memory bank gets full, things start to overflow - and you don't get a choice as to which things. In fact, you don't even know they are gone until you go to try and use them!
The easyest and cheapest way to try is to build a turntable wit footcontrol for use under the microscope. Only a slow motor with foot control for forward and back and a little rubber wheel set on the outside of the turntable.
So you an use the turntable from grs or every other brand or a diy ...
I have sat and used Bryan's turn table too, like Airamp. At the time it worked for me...as I have grown in skills and moved past practice plates it would not work for me now. Anything with a convex or concave area would a bit of a challenge. At least thats what I recall....been a few years plus
