Glass Bedding Techniques

Question

Gene Shuey’s video on glass bedding was very good, but he did not explain the benefits of pressure bedding even though he mentioned he preferred it over other methods. Can anyone tell me what those benefits might be?

Also: I took in an old bolt action 20 ga. shotgun repeater that was in “well used” condition. It is a Sears Roebuck Ranger 141-7. I found that H&R had a similar model # 121, but there are not any parts available at Jack First or Numrich. The part I need is the carrier spoon. It looks like it is a part that acts as the secondary cartridge stop. If I knew what they looked like I could probably make one. Anyone got any info on this gun and or parts Answer:

I don’t know why Gene prefers that method. I prefer whatever works. Some barrels like pressure and some do not. I like fiberglass stocks for many reasons and you cannot pressure bed correctly with fiberglass or plastics, so if you have a gun with a small barrel dia and it likes pressure you would have to have a wood stock.

Answer

The easiest way to do this is, as Ken says, see how it shoots if you free float it. Then stick a couple of business cards between the forend tip and the barrel, trying the groups as you add each card. If this makes for better groups, turn the gun upside down and clamp it into a vise. Pull down on the end of the barrel with a trigger pull gauge and note the weight registered at the point that the card(s) pull out easily. Then, as I said in my 10/22 Tips and Tricks article in GunTech vol 5, “you can also color up some of the ACRAGLAS gel to match the stock and lay about a 2” band in the barrel channel from the fore end tip back. Use the gel so it doesn’t run out because we’re going to put the stock upside down (horizontal) in a vise and hang a 1 fi-2lb weight (in your case, whatever weight the trigger gauge showed) from the muzzle. I use a big crescent wrench with a shoestring through the handle hole (very hi-tech and scientific) and hang it over the muzzle. When the glass sets up, you will have an upward pressure at the fore end tip equal to the weight of the wrench (or other weight). Try the gun before you do this and only do it if it needs help.”
