Hi, Brian: Sorry for the long delay in anwering your last missive to me. I was especially 
intrigued by your assessment of the HP-8640B, and I agree about the drift. It is kind of 
annoying at times, but overall it does what I need it to do.

I was recently given an HP-606 signal generator, but have not yet tried it out. It is 
supposedly better than the 8640AB, but we'll see.

That sounds like a very good method, Brian. If I have some larger holes to fill, I'll probably 
use your method. JB-Weld is good for smaller holes, but I have not yet tried it an large 
ones.

vy 73 for now,

I'll get back to the earlier missive as soon as I can.
