View Full Version : Filler Material on Stock
May 16, 2009, 20:36
My BM62 was fitted with a BM59 stock. There is a cutout on left side for the selector, and on the right for the cam to engage to op rod.
I see M14 stocks that have been filled to cover the selector hole.
What material do I use to fill in this hole?

Most people use glass bedding compound, which can sometimes crack and chip out. I suggest thoroughly degreasing the wood there, and roughing it up to give the glass something to grip onto.

It's called Agra-glass from Brownells. The basic stuff is a brown color when set up and works well with the dark wood stocks.

You can use most any type of compound including steel bedding, JB Weld, fiberglass, etc & use the brown coloring available from Brownells.
Just clean the area & ruff up a bit before applying.

while you CAN use just about any epoxy, you will get different results depending on what you use. Marinetex is by far the best from a functional standpoint, but it is white or dark gray. Acraglass used to be the standard, But I've always found it a lot more tempermental than marinetex. But you can dye it to a shade of brown to match your stock.
If you want to be really clever, you can cut a piece of scrap walnut to tightly fit the notch and glue it in.
bondo type products are not good - they will shrink after a few weeks and JB - well, some of the crappiest repairs I've seen have been with JB Weld. doesn't have the settling ability of marinetex to mold.
I filled the cutout in a fiberglass stock with JB putty. Trimmed with Bondo and topped with Allumahyde 2. I started by first drilling 3 holes in the gap to put rebar ( screws) in so the JB would have some purchase.
Once cured, file for shape to make sure you have uniform heel contact.
I skimmed the job with Bondo/glaze and painted with Allumahyde 2.
It came out Ehh. It has been out in the cold and heat and has not budged that said I would probably try MarineTex if I did it again.

I will try Acraglass since I want to match the color of the wood.

I like Marine Tex because you can make a masking tape mold and "pour" it in. It has good settling properties and can be tweaked to make it more runny by microwaving (but it will harden a lot faster). I also use it for stock texturing.
Just finished this one . .. .
