[R-390] bracket

Mon Jul 12 12:07:07 EDT 2021

I found the wrench and wrench assembly drawings for the Bristo Spline. They
are attached.

Anyone have a hankering to make a bunch of these?

Regards,
Gary

Hopefully, the attached image will come through.  It is from the R-390A
drawing set and confirms that the originally specified screwdriver was a
Vaco P18 #1.  

I thought I would look it up because I tried a #2 as Larry suggested and
thought it fit better than a #1, at least on the captive screws, although I
have had no problems with the #1.

Regards,

Gary

I prefer my XCELITE 99-66.  The extra long blade is very handy (although it
may not be as easily stored on the back of an R390 as the original).
