In the handle section, under the stop motion wheel, there's a washer which has a right right up and a wrong way. It also has a right side OUT - the two little lugs should pint outwards always. But if you took it out, and turned it through 180 degrees and then reassembled, it should work. Arrow is right, having the machine end tilted away from you at this point will enable you to work with the washer without it keep slipping out when you try to put the silver stop motion wheel back in place.
I'm sure we can find a youtube of this if you'd like to see it done before you begin?
As for the burnt thumb, have you considered fitting an LED corn bulb? That should be bright but cold.

Thanks Arrow and LeilaMay, I have done this before, on my 128k handcrank, but so long ago I'd need to refresh my memory before starting. I just don't have the time to tinker with any of them at the moment, so I'll have forgotten it needs doing by the next time I want to use it.
I have thought about replacing the bulb with led and on my featherweights, but again, they only get used occasionally and I need to learn to keep my hands away. I know they get hot, so only myself to blame.
Back on the modern machine and overlocker now, altering sequinned Lycra dancewear. Enjoyed this morning a lot more, doing
on the oldie
