Tool making advice

[Carl Meyer]

Lance,  I've bought some silver solder that you could melt with a soldering
iron.  It's lower temperature than the regular silver solder.  Usually you
will need a torch for the higher temp stuff.

Brazing would work as well and be stronger.  Or, could it be spot welded?
Need to see the configuration to  see.

By the way, brass isn't as good a heat conductor as copper or even aluminum.

My opinion is that all the electric heaters we use in piano work are way too
hot.  It's of course cheaper to use a soldering iron as a source of heat,
but a simple cheap lamp dimmer will cut down the heat and be adjustable.
I have a design for a simple feedback servo to control heat by using a
thermistor to measure the temp and control the current to the heater as
necessary.  It's adjustable and more accurate than a thermostat.  My intent
is to use that concept to make a super-duper shank bender, glue pot, felt
ironer etc etc.  Some day maybe.

Please share your new tool idea.
