I just did. I picked up one of these tools at an auction several years back and never used it.
Now, after reading that auction listing, the light bulb flicked on. Doh! I could easily modify the tool to make a mortising machine to replace my Delta bench top unit.
I owe the guy who was asking about his problems with his mortising machine bits a thank you. I wouldn't have run across that eBay listing if I hadn't been looking to find you a readily available chisel and bit set. Thanks!
