Part 8:

Stock routing & liner prep (cont.)

Okay, that's it for a while. This was my stopping point and I have lots more images to insert and format into the master document. It might be a few weeks before I have another section done.

Pictures?

While I'm trying hard to focus on what's written it seems that the pictures would be helpful. Any chance the pictures could be re-posted? Thanks ahead of time.

Now I see it was made into several PDFs. Thanks, after having an old beater M1A I expect to visit this forum more while I hopefully tune it. It has shot fine but since I'm lightening up the original wood and refinishing the stock and will be reparkerizing it after a crappy Duracoat paint job all because I just got a Leatherwood M 1000. :D

Tony,

Just noticed this thread again and I thought I might make some more suggestions as to common mistakes and how to NOT do them.

1. Mixing the epoxy or "glass" bedding compound. I began glass bedding when we still had to add powdered fiberglass or aluminum to the bedding material during mixing. It required EXTREME mixing so as to not get hard or soft spots and because the early compounds were much more likely to get air bubbles in the mixture. Though modern bedding materials are a LOT more forgiving and most come with aluminum, steel or even titanium pre mixed; THOROUGHLY mixing the material is still necessary for the most uniform bedding. The technique is not unlike what is used to mix spackling, putty or filler compounds for sheet rock inside houses. You have to take something like a 1" wide putty knife and scrape the bedding off the bottom of the glassing plate and fold it onto a pile, then press it out and scrape and fold and stir it again and again. If the directions say to mix it for 5 minutes, then DO IT or the mix may not come out uniform in consitancy and hardness.

2. When you lay bedding material in the stock, you MUST PRESS it in place and so that it sort of mounds or bubbles up around where you are pressing. When you add more compound over it, you MUST press that layer as well so it bubbles or mounds up. What that does is keep air bubbles and voids OUT of the glass job. If you get the material a little too thick, you can spread it around, but you must use some downward pressure when doing so.

One also MUST press some bedding compound on the receiver in all areas one wants the bedding to be after it cures. This is especially important in the corners of the front part of the receiver that will become the top inside corners of the bedding surface. AGAIN, you MUST press it in place until it sort of mounds or bubbles up beyond the knife. It is far, FAR better to put TOO MUCH bedding material in place than not enough. Too much and you just clean it off the receiver and stock after the receiver is locked in place. Too LITTLE bedding compound means you are going to have to glass bed it again to repair the job or do it over.

3. It is almost a "MUST DO" to somehow mark the outside position all around the receiver BEFORE you go cutting out the stock to prepare it for bedding. I usually place masking tape all around the top of the stock- right at the edges of the receiver. Then when I cut into the wood or roughen it, I stay WELL INSIDE the tope lines and preferably about 1/16" inside of the tape lines. That way when you clean up the bedding that squooshes out right to the edge of the receiver, the bedding compound is not as noticeable. Makes it easier to clean up and a more professional looking job to not have bedding material showing outside the receiver.

Now on stocks that have been sanded thin, this can be a problem and especially on the right side of the receiver heel to cut a channel under the receiver heel there for bedding compound to get under the receiver heel there. SOME TIMES when I tape the stock and remove the receiver - there is less than 1/8" of wood between the tape and the bolt channel in the stock. So you can't cut a channel straight down as usual. To get around that, I use a 3/32" cutter and cut a channel at an angle with the top of the angle towards the interior of the stock and route outward on the wood STILL INSIDE the tape lines. You can still get a good amount of bedding under there and not have it show, as long as you angle the channel that way and stay inside the tape lines on the SURFACE of the stock, though the channel holding the bedding material will angle outwards under the surface of the stock where it can't be seen.

Thanks from tonyben and budster
