Fiberglass & Cutout Update
Here's where I'm at. Cut out for the magazine and the trigger assembly, and drilled holes for the action screws. Keep in mind the large cut out will get filled with fiberglass as well and then routed out to the EXACT fitting.
You can see with the fiberglass so far that it's pretty rough. But... I have the basic set up for the buttstock complete. I need to do a few more layers of resin and matting. But, now I can start to continue to wrap the fiberglass up through the trigger handle and through the fore end of the stock. I'll post some more pics up next week.
Sidenote... the fiberglass is extremely firm and rigid. It's rough to work with and sort of a hassle, but once you get the hang of it's really not that difficult. It sands nicely and will be more than durable enough for the project.
