Time flies when you're having fun, the wooden bandsaw now sort of works! Turns out I'm terrible at remembering to take pictures of my work in progress, sorry :-(
The frame is finished, the bearings are mounted, the wheels are trued up, the tensioning and tracking mechanism is installed, and a blade has been put on the machine. I've run it up and, with great care and not a small amount of fear, cut some wood. The crown on the wheels is enough to hold the blade in place for small cuts which feels like a good thing. I've yet to make the covers or the blade guides so I'm staying well out of the way when it's running!
And now for the bad news... The first time I fired the bandsaw up everything went fine but after a few test runs the RCD tripped in the consumer unit. Obviously that made me suspicious but I reset the switch and tried again, it was fine. A few more trials later and now the motor is tripping the RCD every time. It seems to be happening as the centrifugal clutch disengages. When the motor is on the bandsaw it takes longer for it to spin up to speed and the trip happens just as I hear the clutch disengage, with no load it spins up almost instantly (and trips). I'm hoping the motor isn't toast, any advice would be most welcome. The motor is just a bog standard single phase 750W job that you pick up for cheap from eBay.
