Re: Thinking of a Bridgeport CNC Conversion

how are you mitigating backlash in the quill - from it rotating?

Re: How do I hold this

You're going to make 7 of those pie-shaped clamps? I would probably turn them all as you suggest from one piece. It looks like the stock could be held normally with vice jaws - face/turn the back side, then flip and turn/face the steps. Then I would probably drill the holes for each clamp as a place...

Re: Are we allowed to ask here for Tutoring?

The way I've tried to interact with the board members here is to just post my question, in whatever phase of a project I'm planning. Sometimes the questioning starts at the "I have an idea" phase and am wondering where to start, or if it's even possible...

Good luck!

Re: Question about thread dial

Yes, the 127 tooth gear would be a drive train gear and is usually a compound gear to complete the conversion. Another option you might have is to just use a metric thread that is close enough to the inch thread that you want, and will work well enough... Most often, when threading different standar...

Re: Question about thread dial

I'm just going to take a guess that for imperial threading, you will then require a set of transposing gears in the drive line. These are usually 100 and 127 teeth gears (or 47/37 for close enough) when we do metric threading on an imperial lathe, so perhaps just reverse the ratio.

Re: Question about thread dial

Yes, one could derive a formula based on the threads per inch of your lead screw. If your screw is 8tpi, I think a common gear has 32 teeth - some multiple of your lead screw pitch - with graduations every inch or half inch. I would have 4 main graduations and then another set every half. One other ...

Re: Sort of free bronze, zinc, and brass scrap

Care to talk? H Well, yes. Specifically, I had intended on asking about graphite crucibles here as that is what I bought. You and Vakil have correctly described the device as a heater/furnace. It might be imagined better than it really is, but this video illustrates it well enough (not mine). _9ZK_...
