Synthetic stock modification and clean finishing

Post by gherx » 20 May 2019, 3:00 pm

Hi guys,

I'd like to make a few modification to a synthetic stock, just shaving and sculpting a little bit here and there for comfort and grip.

As everyone will know though, the stocks have that smooth finish you get from the injection moulding process, and when you start cutting/sanding plastic it gets a much rougher, unfinished looking surface.

Can anyone suggest any tips for finishing the modded bits of the stock to closer match the original surface?

Thanks.

Progressively finer grit paper?

Spray Putty, sand and paint?

I did the opposite to mine and took to it with a soldering iron to make it less slippery. Blade is right, you need to sand it with finer and finer sandpaper.

Hi guys,

Not keen on the idea of paint, or anything that'll scratch or rub off over time I don't think.

I had wondered about sand paper, but thought at the fine level it might just gum up and not do much.

I'll buy a couple of varieties of grit sheets and see what's what :thumbsup:

Poly stocks are also quite thin. You might be able to shape it with heat perhaps, like working with poly pipe?
