That's so awesome. I feel I missed my vocation - working on a mechanism like that.
for those keeping up with me getting this old deck to run again

it plays back - when i hooked it to an amp it plays back too quickly but that is just the speed adjuster on the motor needs to be looked at
Its still not 100% fixed but atleast i have sorted the big issue it had - now just to work on repairing the broken mounts and getting everything lined up correctly

Your auto stop doesn't seem to be working?
Have a look at this site for idler tyres (the rubber bit you 'bodged' with a few bands).
Also check that the pinch roller is making good contact with the capstan, as in one of your previous videos, I was sure it looked as though the pinch roller wasn't doing it's job properly.
This would make it play fast, and also chew tapes.
By replacing the idler tyre in the fashion you have done, you have (possibly) increased the take up reel torque, which may well be compensating for the pinch roller not working correctly- hence you are now literally dragging the tape through the machine in an uncontrolled fashion.

Cheers for the link fella, i will check it out
getting a tyre that fits will be better than my bodge definatly. I have a new pinch roller to fit - i just havent got round to it yet
In regards to the auto stop it is a very odd system - behind the takeup reel is a little plastic thing with some friction material - this clips into another plastic bar that moves it from left to right depending on if it is playing/ff/rewinding - this goes into a rotating wheel that has buildouts to shove the bar into the middle - if the transport is in forward or reverse the bar goes back to the side but if the bar stays in the middle (Ie the reel isnt turning) then it stays in the middle and a lump pushes it down turning the deck off - this is run from a pulley direct to the motor
It is an odd system, if i get chance i will record it as it is quite amazing to watch

Haha, yes I'm well aware of those weird auto stop systems.
I spent many an hour fixing really, really cheap mechanisms back in the 80's, performing bodges that makes yours pale into insignificance!
A lot of the stuff I used to repair was devoid of spares backup, or even service manuals (hence having to bodge).

yea i have to admit the fact that you can get a fair amount of service manuals online now makes life easier. I was a bit surprised that i could get a belt kit still for this cassette deck and for the reel to reel
Looking at some of these mechs they look overcomplicated just for the sake of it but they are fascinating to watch in action

Just bought an Akai 4000 ds reel to reel from ebay.
I've had a hankering for one of these for years, as my Dad had one in the 1970's, although I used to use it more than he did to records the charts from the radio. Collected if from the seller on saturday and set it up and got it running today, hooked up to an Arcam A85 amp and B&W speakers.
It looks great and works perfectly - RETROTASTIC!
As a bonus the seller (who wasn't the original owner) gave be a box of about 50 reels, mostly catalogged in a notebook by the original owner. I've been playing the tapes today (mostly LP recordings from the 1960's and 1970's) and frankly I'm amazed with the sound quality. Andy Williams, the Carpenters, and Abba (to name a few) all in glorious analogue stereo!
Whoever owned this was fastidious and looked after it properly as it came with the service manual with hand written notes in it in pencil indicating that he has serviced the recorder sometime in the past. Came with the smoked lid too.
I'm going to have a look inside soon and check out the belts, mechanisms and circuitry. Very pleased with my purchase
