Thanks Mike, I came up with the arrow shaft idea by trying to build a better mouse trap, after doing a few and not getting the looks I wanted I thought there has to be someway to make the bedding job look great. After inletting the barrel, I try to have 1/16" around the sides of the barrel so the bedding doesn't break out, then I took a 2512 aluminum arrow cut it 3" long laid it into the stock up to where the recoil lug butted up to it. I like to bed 3" from the recoil lug foreword, to make sure I had enough space between the arrow and barrel I cut strips from a back tag to use as a gauge, I lay 2 strips on top of each other replaced the barrel and had plenty of space for the bedding compound. The trigger area I fill with modeling clay and also the bolt or safety cut out. I wrap 3-4-5- wraps of Blue Painters tape around the barrel up toward the end of the forearm to keep the barrel centered in the stock. The (ramp) is very important for accuracy, the ramp is the area just behind the recoil lug & in front of the trigger along with the very back of the barrel on the LK-93, these areas I use a 1/8" drill bite and put 4-5 hole for anckor points, some are at a 45 degree angle. Once the prep is done I go back and bed the arrow into place and let set for 5-6 hours, t keep the bedding compound in place I use 1/4" door foam as a bridge, in front of the arrow and also behind the arrow.
Now this is very important, I use 1 wrap of electrical tape around the recoil lug, the whole barrel gets a coating with Johnsons Floor Wax, inside the recoil lug along with the recoil bolt, inside where the bolt goes through the stock so nothing will stick. Before I do the recoil bolt I wrap that with tape so to hold it in place in the stock when I apply the bedding compound, where the front of the arrow is I create a dam using 1/4" door foam to keep the bedding compound in place. I use JB-Weld Industrial and it works great, I mix it up pour it into the stock and let it run to where it need to be, lower the barrel slowly onto the recoil bolt and tighten down slowly, clean up the overflow as needed and let set overnight. In the morning loosen up the stock bolt a few turns and give the bolt wrench a sharp blow with a small hammer and everything should break free. If you have any questions just give me a shout. THANKS.
