[R-390] R-390A Wrenches

[Richard Spargur]

Your are correct youu need a bristol wrench. The R-390 and R-390A uses the
#8 spline (aka Bristol Spline). The size I ordered from McMaster-Carr was
the .096 inch. I use it to align it, remove knobs, but it will not reach all
the gear clamps. I can manufacture a tool just like the original spline tool
used with the receiver except instead of using an aluminum rod I use a brass
rod. It lasts longer and is also non-magnetic except for the spline insert.
Attached is a picture of the one I made for myself. The cost will be the
cost of the materials, gas, and shipping probably around $8 to $12 each. Let
me know if you want one. I am not in the business of making tools and will
do it for the fun of it and to keep R-390s and R-390As alive. I am also
happy to tell anyone who wants to know what materials I used, where I got
them, and how I put them together so you can make you own. I have attached a
picture of the one I made and use personally. I assume the list server will
delete the picture. If anyone is interested in it email me directly. It is
the same size and the original tool issued with the early receiver models.

Am I correct in the proper wrench to use is a Bristol and not an Allen ??

Can anyone tell me the sizes I should get (McMaster-Carr has a nice
selection).

Also, IIRC, didn't Xcelite make a set of Bristol Wrenches similar to the
Allen Wrench set I have (or am I dreaming again ??).

Tnx, Dick, W1KSZ
