Dang. I would not want to part with my sander ever. That was my best gift to myself last year. Power tools have spoilt me 😅 nice work #[2] - how did you join the legs to the sitting surface? I was contemplating bar stools but chairs are a lot of work because of its angle precision even though it looks simple, I gave up even before I started 😅

I did a tapered leg (getting wider towards the bottom) into a similarly tapered hole. Then i deilled a hole through the side (see my comment above) and put a peg in so the leg cant go in furhter or slide out. Additionally the hole was slightly smaller than the leg.
Those angle precision dowels are not easy stuff even with machines, let alone by hand. How did you end up picking up carpentry so young? And if you are selling, Nostr has some marketplaces that’s I think is already up
