Put bushes into the rotisserie rollers. In particular, the brake screws were quite ineffective because as they were tightened, the rotisserie hoop deflected through the play in the rollers. This is now fixed and the brake setup works ok.

Also fitted ball bearings into the bottom rollers that support the hoop, as the rubber rollers ran fairly lumpy on their (non-machined) axles.

The hoop now runs as if it was on, well, ball bearings. I was a bit dubious about turning the bearing recesses into the hard rubber rollers, but it worked out surprisingly well.

Also started on the hoop for the tail. I cut out a 750mm OD, 650mm ID ring from an old coffee table and slotted it so it fits over the tail section. Then measured and cut some aluminium angle and SHS to create a support structure around the tailplane attachment bracket.

This setup probably will not require any rollers. The ring is intended to just support the tail on blocks when the fuselage is rotated in the rotisserie, so that the tail section doesn’t sit on its thin skin.
