I had a nice "discussion" with my daughter about purpleheart before I began the project. I am pretty sure that she will not be in love with the color purple as she gets older, which should work out well as the piece changes color. I have seen some aged purpleheart and it had a reddish tint, almost looking like aged padauk.
The Record #4 in my restoration video I bought for $5 and was a pretty easy clean up. There are deals out there, you just have to keep aware. I don't know where you live, but paying $50 for an old #4 is just madness.
A gift piece involved some purpleheart. I visit this person about once a year for one thing or another. The piece sets where it gets a fair amount of secondary sunlight and is the color of dark egg plant (think Welch's Grape Juice) after about 4 years.
I have sort of a hatchet-face, wear glasses and use muffs for hearing protection. Finding a mask that does the job, fits well, is comfortable and that doesn't block my vision is a challenge. AO Safety made a single cartridge mask that I still have an use which is my favorite. 3M saw fit to discontinue it when they absorbed that product line. I saw Philip Lowe wearing one in a video and wrote to him to ask if he had a source for any old stock. He was good enough to write back and we agreed that if either of us found a source we would let the other know ;-)
I use a 3M half mask with the quick-latch for finishing. For dust I use this Miller. The miller meets all my criteria and is inexpensive. It has really become my go-to mask for particulate protection. When you find the mask that works for you I would buy a spare. Manufacturers have a habit of "fixing" things or getting bought. An item as personal as a respirator that fits and works well for you deserves a spare.
