I've looked far and wide for one of these things and so far have come up empty. Grrr. Without it I can't lock the bearing in place. Not sure why the manufacturer would use such a fine pitch.

Unfortunately the tap is about $80 to make one. Any ideas? Tried Mcmaster and a host of other places. :confused: :confused:

Misumi, maybe. Threaded shaft collars or bearing nuts are good places to start. Then see if you can pull individual part numbers off of ballscrew assemblies there.

You're the man :)

In case you need metric stuff in the future, try www.mdmetric.com (maryland metric - has to be close to you). I buy from them long distance all of the time.

Their web site is a bit over whelming, but on the phone, I can figure it out.
