Hi Frank

Alan Gibson makes/made 2 types of 4mm hornblocks and I am guessing you
are talking about the etched variety. These are the only ones on the
market, I know about, without a flange. I have used some, and yes I
found them difficult as well. Difficult and time consuming to make, and
to use on the Master Chassis. Your idea is a good one but you have to
make the plates and clean up the chassis after use. Could you clamp a
plate using those small pegs?, or possible push the chassis right up to
the face of the jig to solder one side, then turn the chassis upside
down (so you don't have to change the settings) and then solder the
other side.

Has anyone else any thoughts?

Regards Phil
