Red Elm, is that a local tree for you? I'll have to google it later.
We also called the toilet seats. The holes were cut on the bandsaw to make Bar Stool seats. I took the pieces home as firewood, they sat around the shop and one thing lead to another and it turned into a $150 sale for the one above. They're not referred to as toilet seats anymore or just throw in a pile of waste. They get treated very gently now.
Whiskey barrels are OK but the wood isn't as good as the Wine barrels. We've had a year of working just with Whiskey Barrels, there are more knots in them, you have to scrape all that char off the inside, for some reason, the outside always looks like they left them in the mud and the pieces in the Heads are more uniform.
I was on a good run once upon a time at the Dump, I had four Workmates and a couple table top ones at one point. With my small 12 x 12 shop, I have to do most of my work on them and they do work nicely.
