8-1/2 inch joiner blades?

Try these folks:

Call them. It's doubtful the item you're looking for is on the web site. With your first order, Ballew usually sends a paper catalog which is quite useful.

Are the knives missing or too worn to regrind?

The existing blades are rusted from spills and other insults. I will be cleaning them using naval jelly, and I am going to have them reground. But I want a spare set, and I don't see any sources on the internet, thus my post. I'll have to replace the switch as well.

Thanks for the responses. Once I have the machine restored I'll post a couple of images. I've been wishing I took some before pictures.

Unless they're terribly rusted, I'm sure they'll clean up just fine. I'd start w/ the wire wheel in the grinder and then move to wet/dry paper w/ water or kerosene or any other wetting fluid. I've found that about the fastest way.

As a suggestion, if these are HSS knives consider carbide for a new set

-- pricey initially, but last longer and if ever do use any manufactured materials they'll stand up...

On the switch, if you want a full mag starter, Grainger has some that aren't too outrageous...
