| I was wired, distracted (plus I think it's time for stronger eye glasses) and just sanded WAY too much off the sides of the block on a KVAR buttstock that was to fit a Chicom receiver...now it's loose as a goose. Can I fatten the block with JB or write off the buttstock...$54 lesson learned. Damn, I knew I shouldn't be messing with it tonite. |
|
Even though it is plastic... give this a try: Take some 3/4" Oak Trim tape (get at a hardware store - it's usually used to "band" the edges of Oak Ply when you build furniture). Cut a chunk for each side, iron on, NOW try your fit :) Bet you'll need to sand it just a bit :) This won't show on the interior. |
I would be extremely careful how THICK you make it. Bondo is not designed to be gobbed on to any surface. Any thicker than a 1/8" and most likely it will just break-off with time. I would just toss the stock and buy a new one. 
|
| Ouch. I hope I don't have to toss it...but that might be the eventual reality. I emailed K-VAR about it so might hear from them (probably say it can't be fixed and should order a new one). I'll experiment on it this week and post my results. Thanks all for your help. |
| Should have been clearer get the fiberglass bondo for boats..my M14 stock is fiberglass..it gets used in tactical classes and gets banged around..bondo still holding after 4 years.You buy that and thae hardner seperate..vehicle bondo shatters when hit but on plastic it or fiberglass it works excellent. |

Tho it aint rocket science, sometimes there's a better way and I'm not familiar with plastics and their different types. I went ahead with the old JB method. Drilled several holes with a fine bit on each side for a good bond, made a form with painters blue tape and poured to an acceptable level. Looks clean and tight. I'll save the good suggestions for future fixes. Thanks again. |
Also drilling the holes at different angles instead of straight down should help hold it better. Rough up the surface also to help bond the epoxy. You could also add a few screws to the stock and grind them down until it just fits the receiver. Then drill your holes and add the epoxy. Good luck. |
It's done and looks/works great. If I have to do it again sometime I'll definately include the screws and angled holes idea....that's excellent. |
