57peppershaker Posted January 29, 2013 Share Posted January 29, 2013 I've got an AMT Dodge Copperhead, that I'm thinking of cutting the windscreen down, old roadster style. Whats the best way to do it, other than very carefully lol. How do I finish to top edge ? Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted January 29, 2013 Share Posted January 29, 2013 I use a cutoff wheel in a Dremel, then finish the edge with files and progressively finer and finer grits of sandpaper. You have to plan and mark your cuts carefully, oversize naturally, hold and support the windshield FIRMLY without allowing it to vibrate or flex and crack, use enough speed so as to melt and cut fairly cleanly. The Dremel will make some melted mess on the edges of the cut that will easily snap off with your fingers. Cutting with a razor saw is usually asking for cracks, as is scoring the clear plastic and attempting to snap it off. PRACTICE on scrap parts until you get the hang of it...it WILL work very well.

Blown03SVT Posted January 29, 2013 Share Posted January 29, 2013 I have done it by covering the winshield front and back with masking tape trimmed trimmed to the edge to protect the glass. Draw your cut line where you like. Use a motor tool at low speed close to your proposed line. Sneak up on the final shape with sandingsticks.

57peppershaker Posted January 29, 2013 Author Share Posted January 29, 2013 Thanks for the advice guys. I've got a couple of scrap ones to practice on. Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted January 30, 2013 Share Posted January 30, 2013 Eric's tape suggestion is a good one...helps to prevent cracking and protects the clear surface in the event of a slip. I usually live a little more dangerously, sometimes to my detriment. Quote Link to comment Share on other sites More sharing options...
