I've been looking forward in watching you finish up your copper puller. One time at work I had a tiny piece of metal get by my prescription safety eye glasses. Whenever I'm in one of the Metro North Railroad Iron Shops working with the grinder. I used an M3 full face respirator. When I'm home and grinding for myself. I use a full face shield I purchased from Harbor Frieght. I believe it's called the Ranger for $20. It doesn't fog up.
