[ARCHIVED THREAD] - Need a 1"x1"x5" piece of dense plastic

Posted: 3/10/2017 12:31:54 AM EDT

Cutting down the buttstock on my old HK-marked Benelli M1. Stock is hollow; I'll have to cut it down, then fit the piece of plastic to the inside, then screw the buttpad to it. I could use wood, but prefer a piece of dense, but not brittle plastic. I'll need to screw through the sides of the stock and into the piece.

Thanks.

McMaster Carr is on your side of town and should have some Delrin or something. Msc direct might also.

Another vote for McMaster-Carr here. From the home page, go to Raw Materials -> Plastics -> Sheets, Bars, and Strips.

FYI, they do not have a brick-and-mortar storefront and will call is only done for businesses. However, I frequently receive orders the very same day I put them in if I've done them before 9 a.m., and I'm in Alpharetta.

UHMW will fit the bill.

Instead of a filler piece could you use epoxy and add threaded inserts? Might add a little weight but going shorter it might help.

If you want to come to my shop in Douglasville I can hook you up. I have drops of several different polymers, UHMW, Polypropylene, nylon, etc.

A cut and glued polymer cutting board might work.

I picked up a piece of.......something. Dense, black, plasticky. I've got the rough shape cut, now to start fitting it, which for me means rasps and file. I REALLY need a belt sander, for lots of reasons. This may make me finally buy one as I'll have to fit the pad as well.

Good luck shaping plastic on a belt sander, you would do better sticking with your rasp. Too much heat is generated on a belt sander and the material you try to remove will melt and weld itself back to the block or quickly clog up the belt. I have had some success with a non-woven silicon carbide abrasive for de-burring and flash removal on plastic but they load up too and stink like hell, use good ventilation and safe shop practices.

Micro-planes do a decent job on polymers, look here: Micro-Plane
