I tried a glue up brush handle with 6 different pieces of wood. Well I gave up on that brush. The joints were uneven which I could have dealt with but the knot cup cracked in 2 spots, which I could have delt with if the glue joints had been even. And I keep having issues with the CA finish witch I would have delt with had it not been for the other 2 issues. But the combined problems make it not worth fiddling with any longer. It was a good learning experience though. And I have some ideas of how to make the next brush very interesting. It's hard to see but there are 2 cracks in the knot cup.
