Daryl,

I've not seen these offered commercially before. However, you might consider 
making up some yourself. You can buy high temperature 'beans' or 'peas' (not 
sure what they _actually_ are) from a cooking shop. They are used to keep an 
otherwise empty pie crust flat when baking - you fill the pie with these 
things, bake, then remove and fill the pie with some yummy stuff at a later 
date.

They should withstand topside wave solder temperature OK. Just sew them into 
some sort of bag... hmm, perhaps made from a non-flammable fabric. 

The idea works OK for the right problem. Pretty cheap too. They might get a bit 
flux-fumey after a while, so perhaps best thought of as a consummable.

If you try it, please let us know how they work.

Peter

P.S. 'Baking' AND 'Sewing' on TechNet - what next?
