Tab Wahsers

Looks like an arbor spacer. These guys used to make them.

They have a milling machine washer on McMaster Carr's online catalog

Of course, you can buy them from MSC (and other Aloris dealers), complete with the adjusting screw and nuts. If all you need is the washers, this can get expensive, of course.

Hmm ... perhaps Errol can get his students to make some punches and dies for blanking them out. :-)

Enjoy, DoN.

Sadly punch and dies are far beyond the ability and ambition of my students (high school sophomores).

Wait, we can do them by EDM. Oh darn, the EDM has been down for more than four years with no $$$$ to fix it.

Sigh.

One magic phrase is "Keyed washers"

McMaster Carr carries them as tabbed washers:

The trick is to look under notched washers. For some reason, "tabbed washers" isn't listed or accessible by search.

If you're actually using these for Aloris toolholders, I've found that threaded clamp collars make a more convenient adjustment than the double nut arrangement that comes with the toolholders. 3/8-24 collars are $2.46/ea from McMaster (p/n 6438K19), probably less from a bearing distributor.

Thanks to all who posted. I haven't found what I was looking for so may go with plain flat washers or look at Ned's suggestion.

BYW I emailed McMaster Carr last night describing what I was looking for and got an email back first thing this morning. They don't have it but that was good response even so.

Thanks again
