Now I do a back axis. I have ground a reducer detail, too have corrected brake disks.
In a reducer I have drilled holes for imitation of an exit of a chain. Behind that having measured length, I cut off a string-chain and I have pasted in a reducer.
I have pasted brake disks, but the reducer left not pasted.
After that I glued details in the following sequence – at first an axis to springs, then after fitting a reducer and the last the electric motor.
