Optical punch

And I made one... it really is a great concept....

Does anyone have an old wrecked clear handle screwdriver? I never throw this stuff away, you never know.... well this philips head unit chipped a shoulder off and as such just wouldnt grip. Today it was put to use. It supplied the required plastic and it even came attached to a mandrel.



Sorry to hijack Tinker.. Ill be gone in a moment... as per the directions on here but I used a piece of brass bar, yet to be profiled and polished...















Works GREAT! Thanks for the idea... :headbang:

I hope it isn't against the rules to link to another forum.

This Evan guy seems to know how to do everything, and has done much of it.  Here's a thread on 'chemical polishing' wherein he uses chemicals to put a finish on certain plastics to make them remarkably clear - directly applicable to this discussion.

chemical polishing

Lew_Merrick_PE:
The company behind the Novus windshield repair companies sells a 2-part chemical buffing system that works quite nicely for most common plastics.  I get mine (they come in foil pouches) from either Interstate Plastics (http://www.interstateplastics.com/) or Plastics International (http://www.plasticsintl.com/ -- who also have the best listing of plastic material properties).  They are relatively expensive ($5 for one set of pouches the last time I bought some -- call it 2007), but easy to use.  They have paper "wipes" impregnated with their goo.  They come in several grades such that the first "wipe" has an abrasive that will polish out nicks and dings such as are found on well-used Trav-A-Dial lenses.  The second "wipe" has solvent-type compound that will give a very nice gloss to the part being polished.
