One of the tragedies of the modern era is that internet forums have died. Their users absorbed into a variety of centralised services owned by one of the four big companies.

I learned from forums and youtube that there should be something inside the joint to ensure the mast can rotate freely. The aforementioned crusty men recommended a two cent coin. Nipping back to 1996 to pick up a handful of change was out of the question thanks to a broken time machine, so I cut a disc of PTFE off the end of a rod I had leftover from another project. That should do nicely. | I learned from forums and youtube that there should be something inside the joint to ensure the mast can rotate freely.

I drilled some holes in it to loosen it up. I broke one drill bit and dulled another on some hidden stainless before giving up. I resorted to a cutoff blade in an angle grinder to mangle the end, being careful not to nick the mast itself. This was cathartic but didn't get me any closer to taking it off. The breakthrough was using a metal blade in a jigsaw to cut through the casting up to the extrusion. This broke the circumference of the casting and gave me a fighting chance of releasing it from the mast. | I drilled some holes in it to loosen it up.

Once I got the old one out it was a simple matter of tidying up the cruft inside the mast, tapping in the new one and riveting it in place. Job done! The initial fit wasn't as snug as I'd hoped, but it was rigidly in place after 3 5mm pop rivets. This joint is only ever in compression, | Once I got the old one out it was a simple matter of tidying up the cruft inside the mast, tapping in the new one and riveting it in place. Job done!
