Ed,
I think you should go ahead with the 3" deep bore. I don't have a 17mm reamer to send you but you can get one for $12.00 (shipped) on eBay. It looks to be a carbide tipped one, maybe used but probably OK on the size.

I would do it as follows:
Make a blank to overall length that is a little oversize on the O.D.
Center drill one end, turn it around
Drill with a 21/64" drill
Bore an inch deep to cleanup & true it
Ream with that tool to full depth
Turn a 3" long plug that the part just barely slides onto it
Finish turn the O.D. and thread it
Done.
