[modeleng] Re: Replacable Tips now silver solder

Hi Harry

I can't argue on that one, after all the leading boiler making expert in the 
UK (Alec Farmer) advocates cooling the boiler with a watering can fitted 
with a rose. I guess all the professional boiler makers must quench their 
boilers, they would take too long to make otherwise. The point I was making 
that (from what I've heard) if you have used silver solder from a dodgy 
source, you run the risk of cracking when quenching.

Regards
Ron
