Hi Friends.
I picked up this thing earlier in the year. Sir Chook was able to identify it as a 1928 SB Standard.
It worked when I got it but being so old, some of the parts have now decided to stop working.
What I'm trying to figure out at the moment is how the gear part that is attached to the drive of the electric motor actually stays on there.
As you can see, there's a notch in it for a woodruff key and the key I have shows evidence of a grub screw being tightened onto it at some point, however, there isn't anywhere that I can see that has a grub screw mechanism of any sort on it.
I now regret NOT taking more photos of it before using it so I could see how it was attached.
There's evidence of some kind of locking collar on the motor side of the gear mech so maybe this is what I'm missing.
If anyone is able to provide any info, maybe even as general as 'This isn't worth trying' I'd be most appreciative.
Cheers,
Dave
