[modeleng] Re: LM&WR, crank pins and track circuits

I would silver solder the crankpin.
Using Tenacity flux and C4, (or whatever it is called these days) the 
resultant joint should be as strong, if not stronger, than welding.

As for the boards, back when I was involved wiv' volts and amps, the minimum 
economic quantity for PCB's was high. Np doubt that has changed, but 
veroboard or making my own PCB's are the two options I would consider.

  My Hunslet threw a crankpin! (early in the day). I haven't got the crank 
off yet, but it looks like it might have been welded.  What is the groups 
views on the best option in replacing it - welding, silver solder or 
loctite?

 I will need a few of these and whilst I can build them on veroboard, I am 
considering getting a PCB made.
