Cut a length of 8mm dia dowel to use as the pivot for the Utility Arm. Then when in work, I found some scrap Aluminium bar the same size, so used some of that. I drilled through the arm with an 8mm dia bit. I then clamped up the piece of Aluminium in a lathe and used emery cloth to smooth over the diameter.
This is now a snug fit, but not to tight once it was push fitted into the arm.
Cut two blocks out of M.D.F. to be the top and bottom dowel location holders & drilled 8mm dia holes in them. Then I cut them across the hole line. So to clamp the pivot pins. I cut clamp block, but the wood broke when the screw was fitted. M.D.F. section also started to split :( so made a block to hold the clamp block to the frame uprights (proper wood lol), then realised, OVERKILL!!!
So just screwed the 1st clamp block into place, using a clearance hole in the top ring.
How I'm going to do the lower arm retainers ??
This idea is again, me following in the footsteps of others:
Victor's R2D2 Build diary (2009).

Stripped the bits and applied more primer.
Sanded the arm again then sprayed it up again, to check finish.
Changed from the screw to a nut and bolt for the clamp block. Removed the lower section to drill the hole and then sprayed both sides with primer.
As all the 'visible' parts will need to be painted.
Then a coat of white on the Utility arm,
then next, will be some nice Red paint!
Just need to add a few clear coats :)
