An arm adventure.
I've been looking for an arm for the Transcriptors Hydraulic Reference (euggghhh! what a name the poor thing has).
Nothing has been forthcoming so I looked again on a box where I had some pieces of arms, all missing some or other vital part like sme couplers, anti-skate mechanism, arm rest, arm lift and so on so I packed all useable bits out on some clean white paper to see if I could put an arm together and machine some absent parts.
The J-shaped armtube with the correct geometry came from an ancient Pioneer arm but I didn't like the cube gimbal so this was the first part I made, complete with two stainless bearing cages.
I've also had to make a new female sme coupler but I had the locking collar.
The old Pioneer's counterweight was a real doodgooi affair so I had to make a new rubber-mounted arm stub for a lighter counterweight I had.
The Pioneer's arm post was not suitable so this was another part which had to be made, together with an upper stainless bearing cage.
And so the job progressed until I was able to wire the armtube yesterday and I'm about to make a new armlift and bias weight. After this, I will have to make an armpost collar.
So far, so good. If it wasn't for the weight on a string bias adjuster this arm will have, I might have kept this mongrel and fitted on of my other arms to the Transcriptors.
