I'm just curious if anyone still uses dental wax to take impressions on inside radius or chamfers? Otherwise what do people use? I have dabbled in using the blue Repro-Rubber, but sometimes that's a bit difficult to get into small spaces.
plastikdreams, how do you remove the Silly Putty without distorting the heck out of it? Do you freeze it with canned air blast or something? The point of this exercise is to get something you can measure or compare to a gage, presumably with some degree of accuracy, and I've never been able to pull or peel Silly Putty off anything without at least a 5-10% stretch or distortion.
This is more of a general inquiry for checking inside chamfers and radii. I do have both an optical compairator and an OGP Smartscope. I am just looking for other alternatives to cutting parts in half to check the radius or chamfer at the bottom of an inside bore. When I say "smaller spaces", I am usually dealing with bores smaller that .250".
You can still find coarse batting, or equally good, coarse webbing, at fabric stores with upholstery supplies. Probably fallen out of mill supply catalogs, but still current in the furniture business.The old-timers often used sisal or excelsior batting dipped in pancake-batter-consistency plaster to cover large areas quickly. The batting also reinforced the plaster, making the cured cast a lot easier to handle. Scotch-Brite-type non-woven fiber -- including floor-buffer pads -- will serve a similar purpose, and is a lot easier to find in today's world.

I've never made much more than pointless threads about pointless stuff.
You obviously know nothing about tooling or you would not make such a comment.
This is what we use.

Just light it with a bic lighter, press it in. It'll cool and be hard in a couple seconds.
Do you need a Practitioner licence to order this though? I've looked at several different products similar to this, but all the other sites said they require a licence to order this.
