soft soldering pads no4 mk1 T

In reading Peter Laidler's article, "Making Up a Useable No.4 Sniper - Part 2." He talks about soft soldering the pads in place while drilling and tapping for the 4ba screws. I was wondering as to how careful you need to be while applying heat to the receiver. It wold seem that a lower temp solder would be safer. At what temperature do you run the risk of damaging the gun?

Thanks

Generally the term soft solder applies to any lead based solder with a working temp of around 750-800 degrees. If done correctly thats not enough heat to damage the reciever.

Thanks for the info..so I should be safe with 430-480 degree..I've also noticed that some people say to use silver bearing solder and others say to NEVER use silver.... are they talking about damage concerns or that silver solder was not original?

Damage concerns. Real silver solder has a working temp of 1200+ degrees.

Thanks for the help.
