Please help me begin to restore my South Bend H-10!! Please!!?

I'd just de-ding the Woodruff key if it were mine. Same principle as the spindle surface. Just remove everything "proud".

When you get ready to put the gear on, stick it in the toaster oven NOT THE MICROWAVE :biggrin: for about 20 minutes @300 f and it should slide right on, but don't stop along the way. The spindle being colder will suck the heat out of the gear and it will shrink down and possibly stick. Be sure, be right, and slide it right on. If it stops, be ready with the mallet and block, because even if it's just a little warmer than the spindle, it will help.

That ding is not going to be any concern as long as there are no high spots on the key.

Those keys work at the shear point, which is the outer circumference of the shaft and the inner circumference of the gear. As long as that area is solid and the key protrudes above the shaft far enough the key will hold just fine and the gear will never rotate on the shaft, which is the keys main function.

However, if you really want to, go ahead and replace the key, it will not hurt and that way, you know you have done a top class job in fixing it.

all thumbs
correction.it's 'burrs' not shavings.
3 sided steel tool with wood handle is burr remover or burr knife.
i just sanded with emery cloth right around the burr edges
after cutting off knocked up part.
you said you didn't have puller.
i certainly would draw that part back on with nut and bolt.
plus put 30 weight oil on it out of the old pump can first.

Have A Nice Day!
 
plus 1 on Tony's heating recommendation -- works really well with a tight slip fit - I also often put the interior piece in the freszer for good measure and when. as here, I cannot, I will sometimes make a sealed plastic bag with ice and shavings and wrap it tightly around the interior shaft just for good measure.

I am going to try Tony's method when SWMBO is out- using her oven (we have no toaster oven anymore).
The key is getting the part from the kitchen down to the lathe using over mitts before it cools.

First, I am going to buy a new woodruff key- just because I want to be sure it will hold.
Then I will getthe gear all assembled.

I would break (chamfer) the edges of the new key on the end near the gear so that the gear will self-align if off the mark a little.

A little under the weather tonight with the stomach flu, so I never got the new key, once I do, I will get that gear mounted.
