DX-100 Project

[Dick Blaney]

We all know that Heath, in the early days, at least, supplied only the
best parts in their kits, with very few exceptions.  One that I ran
into in my DX-100 restoration project was those "el-cheapo" knobs used
for the gray open top Xtal/VFO switch, the red little Drive control,
and in the original version, (pre MK-3), the identical two that were
used for Course/Fine PA loading.  They had 8-32 set screws threaded
into fairly soft plastic, and if you got them tight enough to not slip
on the shaft, the knob would be  deformed and they would slip anyway.
And many eventually split.  My solution was to machine aluminum
inserts, (I'm blessed with a small lathe & machine shop at home), and
epoxy them in place.  The original knob is now just a cosmetic shell
over the metal knob, but all is well, since the metal cannot be seen,
and the things work great.  I can give dimensions to anyone who wopuld
like to try it them selves.  Hope it helps someone.
