    I also have a Hex collet block, but with thin walled tube it has a tendency to be deflected unless you take very light cuts so it's probably not far off as accurate to use a file.

    The first stage of fitting 3D printed brake blocks is the hangers. Sadly the nice cast brass hanger are far too thick for the replacement block so it was either make some new from nickel sheet or try to mill off the shoes from the etches supplied in the kit. with the make new ones as a back up plan I decided I had nothing to lose in trying to mill of the shoes and use the existing brake hanger etches.

    So far so good. I now need to trim off the remains of the shoes, solder the fronts and backs together and then probably file a little more off to make the shoes fit.

    It sounds to me that printing those 3d brake blocks has resulted in an awful lot of extra work to fit them to the hangers. I hope the effort is worth it.

    Not as much work as trying to sort out shorts when the brake shoes touch the wheels... I am sure it will be worth it in the long run.

    This week has seen a bit more progress on the Princess Royal. The brake shoes are now fitted to both sets of hangers. Next job is to remove those already fitted to the tender and replace them and then fit the others to the loco

    I haven't had much time on this since my last post as I was asked to produce a video for the next Gauge O Guild Virtual show in November which was made up from thirteen separate videos and and numerous 'retakes' I hope it was worth it.

    I should be back on the Princess mid next week.
