View Full Version : Fibre glass gurus...


pies10-19-2005, 03:53 AMHey all. im about to start building some fibre glass bits n peices, first of all i need to know, how do i get a mirrored mould for a certain part. eg, flared gaurds. how do i get the left rear flare exactly the same as the right rear flare?

and whats the best "product" to use to get a nice smooth mould?

will ask more as i hit more problems. will also start a pic library i guess hehe turboguy10-19-2005, 05:15 PMUnless you have access to a cnc machine to mill your molds, you won't get an exact mirror. You do it as best as you can, make it look as close as possible, then make the molds. Also, what you make your molds out of depends on how many copies yu are going to make. A plaster mold is really only good for one copy, fiberglass molds for a few, but not a lot, and urethane for commercial molds.

-Jason Mister2.210-19-2005, 05:25 PMYeah you really need a CNC to be exact. But you can get REALLY close if you have the right tools and know-how. You will need to mate your parts side by side.

Once you have one side the right way you can make custom tools that are molded over the first product to match to the second. A lot will be doing things by eye.

The good news is even if its not 100% perfect the chances of anyone ever noticing are slim to none since nobody can see both sides at the same time. Just be as exact as you can.

I still make mistakes sometimes but when I work very slow, things seem to turn out nicer then rushing through. Powered by vBulletin® Version 4.2.5 Copyright © 2026 vBulletin Solutions Inc.
