Ok, here's the question...has anyone tried soldering pewter to another type of metal like copper? If so, does anyone have any tricks or tips they'd like to share with me before I give it a shot? Please? The book says "just be careful with the flame adjustment" and that is the extent of the advise...[Smile] I'd sure appreciate it if I could get a bit more specific advise before I end up melting 20 hours worth of raised pewter goblet! [Smile]

it will depend on how thick the copper is and the pewter and what kind of joint you want to end up with as the pewter solder is a low, low temp solder. I don't think that you will end up with a real strong joint like holding a lot of weight up, or slinging the cup around in Norse traditional drinking chant etc.
Most of the pewter to pewter solder joints are a close match to the solder material.

This is to a brass tube on the back of a belt buckle done by a iron not a torch you still have to move quickly as dally to long in one spot and you will get slumping.

This is a steel buckle back soldered to a cast pewter buckle. I have done a bunch of these and so far none have come back or complained.
As with all soldering, clean clean and clean all parts. Use a good flux I use a liquid leaded came flux for stained glass. Also use a known pewter solder Temp is (300'F) of the proper temp. Not something that is called low temp solder.
I have only used a torch one time on a broken statue type table decoration and it was a pretty heavy weight area and could direct most of the flame away.

Good place to get it generally have it in stock

Unless you practice up it does help with two people one to do the torch and the other to operate the solder wire.To relive this [Smile]

Thanks PT,
Actually, I did get the pewter and the solder from the company you recommended . The pewter is 18g and the copper is various wire and it doesn't have to be super strong, but it does need to be functional...I think I'll practice a bit before I give the final product a try...I could always use industrial epoxy I guess since the joint will be really well diguised...but I have bad luck with epoxy. I hope it works and I can post some pics instead of melting it and then having a melt down myself[HAHA]

I have had luck with a low temp solder. Make sure it melts below the temp of the pewter being used. Here is a pewter vessel with an attached copper rim I made years ago.

A friend fried their pewter syrup pitcher doing the same thing they had done for years, warming the crystallized sugar on a warm hot plate.

Oops, too hot melted the bottom.

I spun a silver base to match the taper of the pewter with a bit extra silver to give it a "foot" (standoff from the heat) below the pewter and then got some prefuxed solder paste rated for below the pewter cleaned and filled the joint. and then soldered in the kitchen oven (previously calibrated with scrap pieces. Worked great. Customer happy.

I suggested doing a double boiler approach with a pan of water. They agreed.
