Hardest Clay? Sorry, forgot the sig

Post by Matt Daughtr » Thu, 24 Jul 1997 04:00:00



I need to find the hardest PC out of all the brands.  I want to form
the clay around a long threaded rod, which will turn inside it.  I
expect the clay to wear down after a while (even though it will be
lubricated), but would like to delay that for as long as possible.
Can someone tell me which brand would be the most suitable?
Thanks.

This may be a daft response, but rather than forming the thread in the
cley, would it be possible to embed a couple of suitable nuts or
threaded tubing in the clay?  Just so long as the adhesion between the
nuts & the clay is good enough to withstand the torque, I *think* that
would work?

Why not get heavy-walled tubing and thread that. Your clay can be formed
around the tubing. Check jewelry-supply or model train/car-type hobby
places for the tubing. They may even have some already threaded stuff.

An alternative, depending on size, is t-nuts. The smallest size that I've
seen is for 6/24 screws. The t-nuts have about a half inch dia. top and a
threaded tube about a half or three-quarters inch long.
