[HBR] How to Build an HBR

[B Smith]

Stop stalling, and start building,  build a BFO circuit first,

 after you master that , grab a Byers chassis and start drilling 
holes, keep it simple, put the power supply on a separate chassis 
etc., if you are nervous about drilling the holes, then order two 
chassis top plates  for  the Byers chassis, if you screw the first one 
up then you have a second to fall back on,  Be prepared to make 
mistakes, don't waste time looking for templates, lay your parts out 
on the top, mark it with masking tape and press on,  if you drill the 
wrong hole, cover it with a small piece  of aluminum and press on.

Then build the audio section and then start on the rest of the project 
working from the audio section backwards. Don't spend years looking 
for a perfect dial and reduction mechanism, just slap on a temporary 
dial and get on with it or just leave the variable installed, with the 
shaft sticking out and  install a crude dial and pointer  and play, 
find the ultimate dial later.  Can't find a 3 stage variable then use 
a two gang variable  for the osc and mixer and a separate cap for the 
RF. Maybe you will find a better capacitor later, so what if you have 
to change a few turns on the coils, you can  rewind a coil in 30 
minutes.
  Don't wait until you have collected every single part of the 
project, otherwise you will never get started.
You are not building a project that has to be perfect, its  just an 
HBR       a "Home Brew Receiver".
