22 barrel liner chamber bore jig

cults3d

For use with a drill press or vise (or by hand like I did I guess). Use appropriate drill bit to bore out large hole half way to match liner OD. (DO NOT DRILL ALL THE WAY THROUGH!) Use #1 drill bit to drill out the smaller guide hole if needed. Use M3x10 bolt and M3 nut (inserted into slot) to tighten down on the barrel liner. Total jig height is 50mm so add 25mm to desired chamber depth and mark your drill bit. (Liner bore is 25mm deep if not over drilled.) FreeCAD model included if you want to make changes.
