If you done mind a bit of disassembly/reassembly then you may be able to tweak the motor back into life like I did a few weeks back:

Hi Alan
Got it going again by spinning the focus ring
Don’t know how long it will last
I will have to use it more often
Thanks for all comments

Mine doesn't get as much use as it should but fortunately it's still working OK.
You may not be aware but there's been changes to the Goth Weekend, the official WGW lost the use of the Spa for the markets and bands and someone else started an event called Tomorrows Ghost, last year they were on separate dates but this year they were combining again, obviously Corona put a stop to that, Tomorrows Ghosts have just recently announced they will not be hosting in November and April next year may be a low key event depending on how the pandemic pans out, I'm assuming WGW will be along the same lines. Last week was the July Steampunk Weekend and despite been canceled many apparantly still turned out.

Hi thanks for all comments it’s gone again
I have looked at the video and read all about
The work involved
I have decided not to risk it so i am going
To stick with it in manual

Hi Neil, if you were ever coming though Sheffield when things have settled down I would happily do it for you. Tried it on my 50-135 and 300 with no problems and subsequently converted it back to sdm (no issues with mine I wanted to see the speed of AF under screw drive, felt fractionally quicker but I wasn’t as keen on the sound)
Or if you wanted to post it I could do it.
Regards
George
