Well I finally got it together.
No dowels too long.
After the first glue-up, I tested the glue on 2 blocks.
The first break was close to where the vice jaws were, so I thought, that may be the vice acted as a fulcrum, forcing the wood to snap off at the top of the vice, so I turned it around, and moved the glue line to the top of the vice, and the wood still broke instead of the glue.
I really am sold on the Hot hide glue strength.
Another advantage….. hot hide will wash out of your clothes!! Which is great for those times, I don’t wear an apron, or just go into the shop for “just one thing” wearing good clothes.
Here it is all clamped up, and sitting level on the table.
Now I just have to give it overnight in the clamps, and then work on cleaning up the squeeze-out with some hot water and a scotch brite/gray synthetic wool pad.
Then it will be time to do the same to the other chair…select a final color and order the leather seats.
