I had seen an article or two on a whale tail joint. I just had to try it. Due to the hurricane my work was cancelled and I had an afternoon to play in the shop.
Here are the websites
I found me a piece of 6/4 sycamore and went to town with my french square. I did not refer back to the original stool because I like to learn on my own. I drew the tail and started to pair the wood with gouges and a pairing chisel.
I drew it with the base of the tail narrow. As well as the tips of the tail are very sharp. That was a big mistake.
My intention was to shape the top of the tails but I had had about enough of the test joint. I had concluded my mistakes and will try this a few more times with a different shape. Please comment and ask questions good or bad. This is new to me and a fun project to try. Thank you for your time and have a great day.
Oh a short video.
