I'm not a pro, but from all I've heard and read, the reason for the grind

is to provide "tooth" to improve the adhesion of teh sticky side of the f
oil
becasue, if the glass is smooth, you lose structural integrity - is that
incorrect?

Grinding the edge will remove any overhanging shards but does nothing
to help the foil stick. *It sticks better to a smooth surface then a
ground one. *

Oh! *Ok, I didn't know that. *I wonder why peopel say grinding is to make it
stick better - maybe teh original idea was to keep the glass from cutting
thorugh the foil, and that got confused with the idea of foil sticking to the
glass...? * It's not important, I'm just curious.

Foil has no structural integrity. *The glue is there just
to hold the foil in place until the solder is applied. *Foil is only
to provide a platform for the solder.

Ok - that actually solves the problem of what to do when you actually do cut
right on the line so to speak, IOW, when teh piece fits almsot perfectly but
gets too small when ground - I had the latter happen just recently, and ended
up wasting glass by cutting another piece...

If you have access to a wet belt sander, it'll provide a substantially
superior edge then a grinder.

No, unfortunately - too many years in apartments leads to a lack of power
tools g!

Thanks for the info, though. *It's very useful

Foil WILL stick better to a slight rougher surface than a smooth
surface. The adhesive on the foil gets embedded into the "rougher"
surface and does provide a better grab. However, our resident King
Troll Dennis is correct in that the foil is only a platform for the
solder to ahere to. Tiffany used bees wax to make his foil stick. If
you doing mostly copper foil work, don't spend the money on a wet
belt. A Glastar grinder will do just fine.
