[modeleng] Re: Solder Qestion

HI,

I would be inclined top make up a shim and solder it in with Comsol. Perhaps 
a brass screw in through the side just to hold the shim in place whilst you 
solder
The main problem is getting a Flux which is aggressive enough to run in and 
clean out the slot to ensure that the solder takes.
In the old days Reeves used to sell a flux called Fluxall, this stuff would 
eat any muck in the area but the Manufacturers had to stop making it because 
of Health and Safety.
I think that the best stuff that you could use now is one of the so called 
self cleaning fast Fluxes as use by Plumbers, One is called Power Flux and 
comes in a Yellow tub. Plumbers use this flux as it is so active they do not 
have to clean the pipes up before soldering as it removes oxides from the 
surface of copper.
You can get it in places like B & Q but make sure that you wash it out 
afterwards as the stuff is so active that it will continue eating at the 
copper after you have finished.

Best of luck

Clif
