How to make windscreen bucks?

[Andrew Rowland]

Hi guys, i've only ever made one and that was a piece of the original resin mould carefully cut off.

So how do you all go about making the mould for a windscreen vac former please?

I have the vac former already!

Cheers

I usually start with a piece of MDF,, shaped then seal it make one vac form then pour the master in fiberglass resin and polish to a good finish.

I do the same as Phil except I use a balsa block,shaped,sanded,primed,filled and smoothed some more. I only need one successful pull before back pouring a resin copy or two. The resin handles the heat better in my experience.
