Quote from: AE_Collector on November 15, 2016, 12:19:30 AMI have been looking at buffers and or grinders a bit lately. I always heard that a 3400 rpm buffer was way to fast to touch plastic so this has prevented me from buying one several times now. While there are 1700 rpm buffers out there the 3400's are much easier to find with several models and price ranges to choose from. There are variable speed grinders so I keep wondering why no variable speed buffers.

Quote from: Ktownphoneco on November 16, 2016, 09:22:16 AMGood tutorial John ! I agree with all of the information you've provided. I've been sanding and buffing bakelite for probably about 20 years, and tried numerous methods, some good, some bad, and finally settled on the method you employ. I discovered a polishing compound you may want to try with your buffing wheel. It's made by DICO, in Utica, NY., and it's called, "PBC", or plastic buffing compound. I buy the round tubes of PBC, but I also think they make it in bar form. It works well in both bakelite and plastic.The one thing I've found with bakelite, and which you touched on, is that I firmly believe telephone companies that produced products in bakelite used different methods and fillers to produce their products. I say that because, as you have also pointed out, results can vary greatly, from one thing to the next while using the exact same procedure for each. Being in Canada, and a restoring a lot of Northern Electric Uniphones, I've noticed different results from one Uniphone case to the next. I've also noticed that the Uniphone cases made with the brown swirled bakelite, or walnut color as the company called it, in most cases polishes a lot better than the black bakelite.Here are some pictures of Uniphones that I've polished over the years. The other thing I wanted to mention with respect to polishing plastic, is the use of a buffing wheel called a "string buff". It works well when polishing parts with a lot of "nooks and crannies" , as the string contours itself around whatever is being polished.John if you'd like to try the DICO PBC polishing compound, let me know and I'll put half a tube in the mail for you to try.Enjoy the day.Jeff Lamb
