HMS K9. Servo rodsOnly 2 of the four servo rods were long enough, so I had to remake the other two from 1/16 inch brass rod. Initially the rods were very tight in the seals so I started by carefully polishing those with a fine abrasive pad. I need to strike a careful balance between just free enough for the servos to slide in them, but not too much so the seals could leak. Once a reasonable slide had been achieved, working them further using Vaselene eased the action a little more. This took most of Thursday and part of today.
Next was shaping the rods to the servos, having carefully looked at the various photos kindly posted. None is quite like my set up, so I am using general principles. The rods must move as axially straight through the seals as possible, not foul each other or the Rx, and allow full angle of movement on the arms. It is like trying to solve a 3D wire puzzle. Two big motor capacitor solder blobs were in direct line of the outer rods and had to be routed around. Still needs a little tweaking.
I am buying a 4 channel servo tester so that I can check out the operation of these, without having to wait until the rest of the electrics are commissioned.
This compartment contains most of the major challenges, and will be
very tight for space once everything is fitted in and wired.
I am making some progress though . . . . . .
