Hi guys, I'm restoring an old SM300. SO far so good or almost. the dial screws are very hard to remove. I already broke two blades' tip. I put a drop of oil on them during the night but I can't catch the slot of the screws. I would be very angry to break the feet. it'as a 1963, no need to tell about its value... thanks
If you end up knackering the movement plate I think I have a nice one you can have. Let me check when I am home later.
I thought using a drill. I don' really care about the plate, I have another one. The thing is that if i go to deep, I will drill the feet too, so back to zero... The tritium of the hands simply exploded when i took the movement out. Befoir I even had time to remove them. There's some work to be done. And "let it no be"
What about using a dremmel to grind a thin line out of the plate where the screws are. I think Al mentioned some type of acid to desolve screws too.
I thought of that too. Drilling outside the plate at the level of the screws hand. That is ethically not good!
If you don't care about the rest, then use alum to dissolve the screws out, or take it to someone who knows what they are doing...
