my 12 year old son wants me to tumble some colored glass. I have done a few peices in my 3 lb tumbler, but it is going to be tied up for awhile and my homemade tumbler should be ready to roll in the next couple weeks, but the barrel is going to be pvc, do you think this will cause a problem with the material sliding instead of tumbling?
what we have for material is plenty of old late 1800's broken and chipped glass power line insulators. we have a old line that is defuct that goes right by our house and most of the poles are laying down, I told him we would not damage good ones,but there are lots of broken insulators too,blue and green mostly.
Any glass tumbling do's don'ts or recomondations?

Since glass is fairly soft, you could probably get away with using builders sand for your rough tumble, and save on the cost of 60/90 SC grit. Other than that, it would be just like tumbling Apache Tears.

I have tumbled a lot of glass with no problems. I only run mine about three days in 60/90. It does produce some gas. I call it artifical sea glass. I have tumbled broken insulators from old telephone poles,turned out good. My glass is frosted not polished. Builders sand should work good. Thanks for the tip, Jake.

Glass runs pretty good. Some outgassing in the early stage. You want to cushion the load in the later stages. Run it alone or with obsidians. Polishing can be a bit of a bugger- probably stick with cerium oxide or tin oxide. Just a word or warning. Defunct rail lines are still railroad property, so unless the property has been deeded back to you, check with the line owner to be sure removal of property is legal (ya ya ya I know- but I also know someone who got into a bit of hot water with the rail road company for selling date nails- better safe than sorry)

no worries and no problems, these have not been on railroad property for a long time after the railroad abandoned the line and gave it back to the landowners, so all clear there. yes the railroad can get owly about the weirdest things around here too.
