Building an old comparator tool…

[tmac1956]

All:

Has anyone ever built one of these or might have some plans for building one? I know Daniels shows one in his book and, based upon past experience, I think it would come in handy when tring to take small direct measurments such as an inside face-to-face plate dimension.

They come up on eBay occasionally, but there’s no way I am going to pay what they usually go for. Besides, I can build one (or should be able to)…

Thanks!
Tom

Have you considered buying one, copying it and then selling it on. Make a few and sell them too?

You can do it Tom!

Guys…

At this point I’m having a hard time building dang T nuts. But, I need something in a machining project so I might give it a try.

Thanks!

Tom,
Build a prototype first out of a soft, easy to machine material such as plastic and get used to working the geometries without fighting the metal cutting issues.

David:

That’s a great suggestion and one that will definitely take!

Thanks!

Tom,
Grey PVC is fairly inexpensive and can be purchased in square or rectangular sheets. It machines almost as easily as machinable wax. Check with MSC.
