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 - Kris- Hide quoted text - - Show quoted text - 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. |
