Diamond belt sanders for polishing glass

It sounds like a characteristic of the glass itself. Is it porous and bubbly? I'm not real familiar with this type of glass.

As you saw in Charles post, you have a series of grit sizes you use to get your finish finer and finer. Your final step is the cork belt to actually polish the edge. This is all done with water on the belt. 80 grit is real rough. I would start with the 220 and work down from there.

As far as the belt width goes, It's all about surface area. The wider your belt the more edge you can swipe in the same time. This makes your work go faster on the long edges. So you can achieve the same result with series of

1" belts as 4" , you just put in a lot more elbow grease. You also have to be more careful working the edges of the belt so as not to gouge your finish. A wider belt makes that a bit easier. The wider belts will last longer too if you work them right. Don't use to much force on them.You can strip the diamond/abrasive/cork right of the belt pushing to hard. Just let the belt do the work.

Now don't forget to wear your slip resistant safety shoes, eye protection with side shields, ear plugs, gloves, a hard hat, and have a second person as a watch out in case you faint or something,.....it could happen..... Wear a respirator in case you make some dry dust, do not wear a tie, no long sleeves, no long hair, watches or rings. If you have facial hair, shave it. You want your OSHA approved respirator to pass the fit test. Make sure you're certified for belt sander use. Have your MSDS sheets for silica dust handy, along with your safe operating procedure guide lines for your belt sander. (you might forget how to use it from when you were certified) You might consider a back up generator in case of brown outs. Make sure you have your permits from the air pollution control district first. They have been known to shut down bakeries for "the smell of baked bread". You don't dare run that Honda without your permit.

Oh and most important of all , declare what gender you perceive yourself as today. That's so we know what bathrooms you'll be using.

That's how we do things in Comi-fornia. I Sure hope I didn't miss anything..
