Silver Solder Question #2

>Spence - I don't think you have to get too technical about it. Many people just grind corners off cobalt stock to fit the hole you have drilled and use CA glue. Then heat gently with a propane torch when you want to remove and update the bit. On boring bars I have used set screws. If you use drill rod for ornament hollowers etc. and small boring tools you can just grind the end of the drill rod.

>Spence,

Go witha half lap. End butting is OK if you are welding but weak when soldered.

>Have you ever used any silver solder before? Lapped would be stronger.Here a page describing the process,takes a oxy acet torch to do it on copper pipe. I do it occassionally for strength of bond and in very tight places.(plumber)

Nobody has mentioned silver solder flux. You get a much stronger joint if you use flux with the silver solder. In fact sometimes it won't even flow into the metal without it.

I use half lap joints but if you didn't let the tip hang out very far and had a good flat bonding surface, just layint the tool on top of the steel would probably work.

I use Mapp gass. Silver solder comes in different grades that have different melting temperatures so you can solder one part using the high heat solder and then solder another part to that one using a lower heat.

>You will want to locate some black flux as it is inteneded for brazing steel with silver alloys. Also the solder you mentioned below is not what you want to use. I recomend asking your local jeweler if you could buy some from them, they are sure to have a ready stock of it. If your local jeweler is not willing any jewelry supply house will have it.

>I got a Mapp gas torch and some low temp silver solder that had a can of flux with it at Home Depot. Silver soldering a 3/16" tool bit to a flat ground on 5/16" drill rod was a snap.

Thanks Folks! Hopefully....
