Can anyone share if the mortising chisel/bits shank is a standard size? In other words, if I buy the mortising attachment, will I be able to find chisel/bits at my local woodworking shop?

The shanks on the Shopsmith mortising chisels are 5/8". I was able to find some chisel and bit sets that worked for me at Rockler.

Do you use your mortising tool often? I don't have one and was thinking about adding one to my tool collection.

I have used it a few times in the last 5 years.

I acquired some(AMT) with 3/4" shanks with my 510.

AMT = Alternative Minimum Tax or Aircraft Maintenance Technology or Advanced Media Technology.

Mortising on the Shopsmith is not one of it's strong suits because of table flexing, so if you're going to go that way you'll need to provide some support under the table to increase it's rigidity. A length of 4x4 or 2x4 from the floor to the under side of the table and placed directly under the spindle will make for much better mortising.

Thanks for the reminder. I did see in one of the saw dust sessions that the extra support was needed. Not sure if using the ShopSmith for mortises or using a plunge router would be more efficient?

The Vintage Machine site provides some tremendous reading and some information that is hard to find anywhere else.
As for not recognizing the acronym, I guess I am just too dependent on having it identified (the first time it is used in any writing).
