I have been working on a few custom 10/22 stocks,durring the process I thought it could be a accuracy enhancement to fabricate bedding pillars, which took me down a different road but the results have been worth it.
It started out with removing the factory wood stocks brass take down screw cup, more of a washer than a pillar really, there is a fair amount of wood between the take down screw cup, screw, and receive lug, .615" to be exact. Here are a few pics of the new pillars next to the factory cup.
Enlarging the factory hole to allow bedding of full length pillar
Preparing for bedding, putty with a layer of e-tape on sides of lug
stock after bedding pillar, 3.25" of barrel in front of lug supported, allowing action to "float"
More to come.......
