TO-1 redo
I just modified one for a friend with no cash. Filed down the inside of the 3/8 grooves and epoxied a one piece base from a Marlin 336 onto it. With the centering drill bit combo from Lee Valley drilled the 4 holes through the new base into the TO-1. Tapped them and installed #8 screws and it's solid like a rock and not bad looking. Should have taken some pics but you get the idea. It's a shame this TO-1 base is a tip off base with so many Lee Enfields around.
