Now that you mention it, yes, Tmuir. I wouldn't have if not for your suggestion. I have router a bit that does a semicircle, I'll set it to barely penetrate the top wood. Enough to do the job. I'm also wondering how I'm going to slope the fronts of the prison walls downwards. Maybe a french curve? Template? Not sure yet.
I would love any other suggestions. I'm just starting out, and not familiar with the features of a high quality bench.
Nope, it looks like in the picture in my previous post around the entire barrel wall.
As far as I can tell, the current spring is no different from all other Generale Ressorts springs I've handled. The GR spring feels quite a bit stiffer and more springy compared to the original spring which felt softer.
It does not. The barrel rotates freely around the arbor and there are no hick-ups in the train.
