Smoothing Sharp, Rough Edges Of Cut Glass Question
Is their a way to "sand" down the sharp, rough edges of
cut plate glass so that they're smooth? If there is a way to do it, what do you use and how do you go about doing it? Randy |

Randy wet/dry sandpaper on a sanding block if you only have a little to do. rub the edge with another piece of glass will make it lots less sharp too. belt sander or grinder if you have a lot. |

If you you're doing it by hand, Emory cloth tape, or sand paper, with about
a med. grit. Coarse might cause chipping of the edge. If you're using a machine of any kind you will need to add water to it Randy Hansen SC Glass Tech.

I agree with Randy H; for a small amount of sanding any old medium grit sandpaper will do. If hand rubbing a lot (or for other future work), a diamond hand sanding block about 180 grit does an excellent job, and lasts for at least a year if you are careful not to rub corners of glass in the same spot etc. These are $22 here in Australia, and should be available from glazing supply companies around the globe I imagine. If using a machine, you should use water, and from glazing company suppliers (or abrasives supplier) you should be able to get some silicone carbide belts, made especially for glass sanding. -- Regards, Les e-mail munged, remove the obvious to reply direct These opinions are mine, not those of my employer.

Ok, true. I read it as just wanting to take the sharp edges off, and sure a rub with any old medium grit (wet & dry or dry rub) sandpaper will do this. It wears out quickly though, so for long term work of this nature you'd need to consider a hand belt sander with silicone carbide belts, or a diamond pad. For better edgework, I suggest a local glass shop with an FEP (flat edge polish) machine, upright belt arrisser, or a pencil edge machine. -- Regards, Les e-mail munged, remove the obvious to reply direct These opinions are mine, not those of my employer.

Golly gee - cut plate glass is cheap. Emery cloth is cheap. Medical
repairs of fingers testing sharp edges awkwardly may be expensive, but probably is not. WARNING: if you drop the glass, you will make the sharp edges worse - it is almost impossible to make them more sharp - worse - with the following technique. Get some cheap glass scraps. Get a block of wood. Get an assortment pack of wet or dry black emery cloth "sand paper". Wrap a piece of the medium cloth around the block of wood. Observe the sharp edge of the glass in good light to observe how fine the sharp line it. Holding wood at 45° angle to glass edge, gently stroke the sharp edge with a couple or 3 longish strokes. Observe the increase in width of the sharpness from almost nothing to a fine white line. Gently stroke the line sideways [hoping you have tested a knive blade in your life without cutting yourself - otherwise find an expert to learn how to do this] to observe the loss of sharpness. Decide how unsharp you want the glass and continue the process if you wish. A - Using finer grit paper, you can reduce the drag of the whiteness - smooth it. With other materials you may be able to polish it. B - Using a rounded groove cut in the wood, try making a rounded over edge (work involved, time also.) With the flat wood, you may be able to make a pencil edge. -- Mike Firth Hot Glass Bits Furnace Working Website http://users.ticnet.com/mikefirth/hotbit45.htm Latest notes http://users.ticnet.com/mikefirth/NTBowl.htm Once again, Empty Bowls will collect for the North Texas food banks - donate.

Golly gee - a Texas Euphamism?
cut plate glass is cheap. Emery cloth is cheap. Medical repairs of fingers testing sharp edges awkwardly may be expensive, but probably is not. WARNING: if you drop the glass, you will make the sharp edges worse - it is almost impossible to make them more sharp - worse - with the following technique. WHO asked about cheap? Run the tool "up" the edge and see what the chips look like and how they "improve" the look of your "cheap"(how thick is the plate? 1/2" table top? cheap?)plate glass. Mike's right, you can't, most likely , make it sharper, but you can make it uglier. Get some cheap glass scraps. From where? Get a block of wood. Get an assortment pack of wet or dry black emery cloth "sand paper". Wrap a piece of the medium cloth around the block of wood. Observe the sharp edge of the glass in good light to observe how fine the sharp line it. Holding wood at 45° angle to glass edge, gently stroke the sharp edge with a couple or 3 longish strokes. Why not use a disc sander with PSA (pressure sensitive adhesive) back silicon carbide disc, aluminum oxide is available in MOST hardware stores, you could even use a belt sander, same material on the belts HOld a angle to the edge, just be sure that the direction of motion, disc or belt is "toward" the edge, not toward the center of the glass. Continue until you, or the glass, has had enough. Still easier to see than explain. Observe the increase in width of the sharpness from almost nothing to a fine white line. Gently stroke the line sideways [hoping you have tested a knive blade in your life without cutting yourself - otherwise find an expert to learn how to do this] to observe the loss of sharpness.
