Columbian 108 is finished--finally. Here are some pix of my 108 and the new jaws I made for it. Not the most high-tech solution, but it works for me. I simply took two 8.5" X 1" X 2" blocks of grade 2 tool steel, had a friend of mine drill two 1 1/8" D X 3/4" deep holes on center, and put one 1" D X 3/4" thick type N52 rare earth magnet in each hole. Then,
I let nature and physics do the rest--nice new jaw inserts for the 108. Let me tell you, those magnets are STRONG. I need both hands to slide the inserts off and once off, I have to keep them apart.The mags are rated for 90 pounds of pull. I believe it!
Oh, how do like my hose clamp handle detents? Again, low tech, but hey, it keeps that bar from smashing my hand.
