Pete, you're a clever devil! That looks like something my Dad would have cooked up. His garage was full of home made tools, and all they did was exactly what they were supposed to do.
Nice job, and thanks for sharing.
I'm a much better carpenter than my Dad ever was, but he was a lot smarter than I.
Mark- after reading all these posts, I realised that I was probably the only one doing this, which does not seem possible. When I was making lures to sell (20 yrs ago),I used a router with a full round over bit (20mm) to do this. I made multiple baits on a plank (about 15 at a time) which was pretty quick, but they still had to be sanded. Now I only make a few for my own use / amusment and the sander does a good job, it's quick, safer and does not annoy the neighbours. pete
