after making room for the folder , btw, make sure the top front of the stock is level with the hinge of the folder.
i installed the rear swivel, i used a nail to hold it in and made grooves for the nail, see pic below.
after much thought about how to attach the two sides , i decided the kiss method is best , i used allen cap screws #8-32 simply bcos the heads wasnt too large and it doesnt need to be painted black altho i'll have to paint the nuts.
on a drill press, i drilled thru the back of the metal folder, i then assembled one of the sides and using the drilled hole as a guide i drilled thru the one side, then i assembled both sides and again drilled thru the hole thru both sides. i repeated this process for the other two holes.
next time, i'll drill two holes thru the arm of the metal folder , one in the front and one in the back, this will give it more rigidity.
i glued pieces of compressed wood biscuits to the inside walls to stop the wobbling.
the folder buttplate is smaller than the standard buttplate so the back end will sit higher , i simple let it protrude and block the openning with electrician tape.
i filed the sharp edges, even the high section i filed it down to level both the sides , i then sprayed "minwax fast-drying polyurethane clear gloss" to give it back the shine.
so there it is, its really comfy to use. alittle more work than i thought , next time i will invest in a new dremel. lol.
i cant wait to try it on a real wood stock.
