I'm working on restoring a 100+ year old Century repulsion start motor and I find myself in need of a 1-7/16" socket with at least 7 inches of bolt clearance.
The armature shaft has a badly worn front journal (90 thou) and the PTO portion of it is chewed up severely as if it spun a pulley at one point. Unlike modern motors, the shaft appears to be keyed to the rotor and held in place by way of a nut on one end. This leads me to believe it's probably not an extraordinarily tight press fit. I'm hoping to press out the tired old shaft, turn a new one and press the replacement back in. But to do that... I, uh...
Well, see for yourself.
Anyone got any tricks up their sleeve for making one-off sockets like this or know where a guy might be able to find such a beast?
Could I get away with just grinding a sacrificial socket in half and TIG welding a length of pipe in the middle? Or is there a simpler and easier solution I'm not seeing?
Thanks.
