Grip/Wood Filler

[Shotgun Franklin]

I have a set of grips that warped a bit leaving a gap at the top along the top of the grip frame. I think I want to put some kinda filler in between the wood and frame. I was thinking of using the 'glass' like you use to bed a rifle but can't find a small container of the stuff. I bought some Elmer's Carpenter's Wood Filler but aren't sure about it? I do want to be able to take the grip frame apart as needed.

The easiest way of matching up the filler to the existing wood (well sort of) is to apply the filler and while it is still wet, sand the grips and work the  the sanding dust into the surface of the filler. I would suggest that you take the sadnding dust from the back side of the grip. You can also just collect the sanding dust and mix it with the filler and then apply it with a final dusting of the area while the filler is still wet, but that takes a lot more sanding dust. It isn't perfect, but it's better than a gap to look at.

Nother suggestion, first you'll have to coat the grip frame with a releasing agent, like Vaseline, or your grips will become a permanent part of the gun   Next step is to get some two part 5 minute epoxy from the local hardware and mix in some sanding/saw dust, preferably some dark stuff.  Apply enough to fill the gaps, let it set up and then sand it to shape.
There is no way to match color "exactly" and no filler will stain to match.  You hope for "close" and go from there.  If the gaps are small enough, your the only person who will see the repair.

Instead of vasoline try wax paper lay the wax paper on th frame tape it down. just another way to skin that cat.

Johnson's Paste Wax makes an excellent release agent.

Very impractical to try and use wax paper with "one" piece grips.  You need a releasing agent like Vaseline or even paste wax.  Carpenters wood filler is simply Tightbond or some such mixed with fine sanding dust.  No real strength to the stuff and will chip off very easily. 
Stick with Epoxy.

I have the grip temporarily 'fixed' with wood filler but intend to use epoxy for a permanent fix.
I need a source for a small amount of epoxy, around here I'm only finding it in bigger tubes.

Use a relatively slow cure epoxy the fast cure stuff will get brittle. WM

I get mine at real hardware stores.  (That means ones where the guy waiting on you most likely owns the bussiness.)  I get a lot of my stuff I use for projects there.  I only use the big box stores if I can't get it anywhere else.  It ain't worth paying slightly less to be treated like shit poop.  Besides the more we use them the more of them there will be when you need them.
