I use my dust collector with a collection hood directly over my lathe and make sure that not only the dust collector is fully grounded but also the 4" line from the hood to the collector. I change out the collector bag before hand too. I don't want to mix foam and wood dust but also a new bag gives the best dust collection. I use a full face shield and spray it with fabric softener before I start. No helping the clothes, they're gonna get foam dust all over them.Genuinely curious, how exactly do you get ready for that? If there's a smart way to manage statically charged foam dust I'd love to hear about it.
Yep! Epoxy is too hard. I use gorilla glue (urethane). It expands so you need to clamp it while it sets. Still, gorilla glue is harder than foam. If the discs are big enough, I leave a couple inches near the circumference unglued.I also avoid using epoxy - it is so much harder than the foam, that the foam tends to sand away faster, and you get tell-tale ridges wherever there is epoxy. The best thing I've found so far for glue is the expanding foam that you use to fill gaps around the house.
