I bought a old really beat up rifle with a (repaired) damaged stock with a partial break through the wrist. When I got the rifle it had been repaired buy drilling a hole through the stock from the inside behind the trigger area down through the bottom of the stock and out the grip bottom. A length of all thread with a nut and washer on both ends inserted and tightened to stabilize the cracked area of the stock. A notch has been cut into the grip cap area to keep the nut and washer below the grip. The all thread was actually protruding below the grip so I dremeled/cut it down to below the area of the grip. (I loosened the all thread and expanded the crack and pumped and forced in clear Gorilla Glue and re-clamped it.)

I need/want to apply a "filler or putty" to cover the repairs and then smooth and shape the repairs and paint over them.

I hope to find a truly non shrinking filler to do the repair. What to use..?

A small batch of the non-running Acraglas gel product from Brownells is can be dyed with a drop or two of Rustoleum 1 hour stain. You can also use your smartphone and the Home Depot color matching app in sunlight to order a sample of the light and dark highlight acrylic paint to touch up. Then apply True Oil seal coat.

There are several examples here in this thread and the linked thread: https://www.rimfirecentral.com/posts/12878779/

 

If it's going to be painted, JB Weld.

 

I worry that JB Weld will be to hard to finish shape after drying...?

 

I just happen to have some in my workroom... Never done JB Weld but it looks like today is the day.

 

JB Weld makes a $7 Kwikwood product that cures light tan. It's available at most online, hardware, and big box stores, e.g. Walmart

 

Get some hardwood sawdust like walnut and mix it with exterior wood glue to make a paste. This makes a very good wood filler.

 

I would cut a rectangular piece of wood to roughly fill that hole and then fill with some bondo if you are going to paint it.

 

JB weld. Use a strip of tape around the grip cap to hold JB in place. Build a dam.

 

Ended up going with Trapt's advise and got the JB Weld Kwikwood Product. Followed directions and after an hour I went with some wood files and rough shaped it. I have already put a dab of paint on it but should haven filled it a little better. I will probably sand the cap area down and see if I can do a little better job. Still pretty happy with the improvement.

 

I would cut off the bottom of the pistol grip and use a epoxy and glue a new piece of nice wood onto the end. Reprofiling would be easy and a much nicer look than any JB/whatever mix! Further I would have taken out the screw cleaned out the drill hole and used an epoxy to stabilze the pistol grip.

 

Good solutions! When I've got it shooting well, can I send you the stock for finish work? Serious, Mike =]

 

The last picture looks pretty good, yes, the epoxy would have been better than the nuts top and bottom. Very nice offer to perform the repairs; so nice to have this site as a resource. Hope the rifle gives years of reliable service. If it doesn't, then just ask again how to properly repair it.

 

Looks like Anschutz or Walther rifle? Those stocks have a fragile wrist area by design, but keep your trigger hand in good position.
