With the first chair I tried a couple of approaches to stripping off the black paint. First I tried a hot air gun. Which was not terribly effective. So I moved on to paint stripper and wire wool.
Last year I bought myself a serious dust extractor for use in the workshop. It has a huge dust collection bag and a 100mm hose.I have it sat between my bandsaw and my lathe. The bandsaw has a specific dust port for connecting this type of extractor to which makes life easy. The lathe on the other hand is not so easy.
