This is a steel adapter that lets you change the hand crank on your Bridgeport or a copy of it. Hardened steel has been heated up to make it stronger and more durable.
Use a battery-powered drill motor with a 1/2 inch chuck to lift that knee up and down.
This will work with any mill that has a.625 shaft and a 9 cog interface, like this one.
Use any 7/8″ wrench to make a lever.
A 9-cog interface is required for this tool to work on Bridgeports, Comets and Encos. It will also work on Victors, Jets, Alliant, Sharp, Chevalier, and Webb.
I think the pictures say it all, so I don’t think I need to say more. This is very bad, and it isn’t even close to being finished. To fit the.625 shaft of a bridgeport knee, the inside bore needs to be made a little bigger. The socket is useless in this state. : I’m waiting to see if the next one is any better.
