A couple of jobs done today...the smokebox rivets needed peening over on the inside and the regulator access cover plate needed some 12BA screws.
A bit of time was spent assessing the design of the regulator stuffing box, the info I have is minimal and the supplied plans don't look right when laid out on CAD. A bit of rescaling based on some photos helped get a larger diameter than the supplied plans (still needs to be made oval), as it looked too small and the gland arrangement was not correct. It's a central feature of the smokebox so a more correct version will pay off in the long run.
Happy steaming!
