Off the top of my head I used the Devcon 10110 plastic steel. A Dremel did a great job increasing the stock inlet on my new laminate stock to make room for the Devcon. I used plumber's putty to patch up all the little nooks and crannies in the action and stock before pouring in the Devcon. Here is where everything went wrong: I didn't realize that the hole for the front action screw went all the way into the action. I filled the hole with putty as with everything else. When I married up the action to the stock I figured that if the action screws were covered in release agent I could just push them into place and tighten them to get a good fit and eliminate the need to wrap the whole thing in bike inner-tubes as I've seen. When I pushed through the action screw it pushed a whole bunch of putty and Devcon into the chamber ----- big ass panic moment -----
I took me a good 20 minutes of furious cleaning with aerosol brake cleaner to clean out my action and in the process I made a gigantic mess. Once everything was done I did a rush job to seal everything up and put the action back into the stock. The problem is that the Devcon had set a little bit so the end result has some small air pockets. It doesn't look terrible and functionally I'm sure it's fine but I'm not satisfied with the end result.
Some pointers:
I used Kiwi wax as a release agent and it worked great.
If I had to do it again there are two MUST DOs that I would correct;
First, make sure you have long screws that you can screw into the action and that will protrude out the bottom of the stock. I didn't do this and it cost me dearly.
Second, find a fairly thick putty, one that won't start to droop or mix in with the Devcon when you squeeze everything together. When I was done I found that in some spots I had layers of Devcon / putty Devcon / putty. I just cut out the contaminated parts but this ended up removing some of the bedding surface.
For the particular putty I was using it was a massive undertaking to try and clean it out from all the little bits of the action. In the end I found that Break Free gun solvent / lube did a good job cleaning it out.
So there's my horror story. In the end things worked out well. However, living in a condo and not having much of a work bench, the mess it generated and frustration are making me think that I'll get someone with more experience to do it properly.
That brings me back to the original post. Most of the reading I did prior to doing bedding was about the Devcon. I haven't heard too much about Accu-glass and the only reason it caught my ear is because you hear folks saying that they have their actions "glass bedded". I wondering if there is a difference or an advantage.
Oh, and note for newbies ... I'm a newbie too ... bedding is 100% do-able, just prepare and plan and things should go well.
