Re: Soft solder as a seal

I like the idea of soft solder seals since they are easy to apply, automatically of the correct size and shape and both soft and thin in section. I recently had problems sealing the joint between the spirit cup and the upper and lower parts of a silent burner. I eventually gave up on fibre washers - they generally split before I could get them tight enough to seal. I made lead seals (similar to those between tank and burner) which worked in no time at all.
