Singer 31-15: How far can I go before I get myself in trouble?
I have a 31-15 that I started to restore last year then set aside.
Pulled it out today and got back to it.
(I know it's not traditional but I think it'll look quite nice in maroon)
The internals aren't rusted - but neither are they nice. Let's call it mild surface corrosion.
Not in the needle bar area but inside the upper housing and underneath.
How far can I take things apart before I get into trouble?
By that I mean there doesn't seem to be a "shop manual" for these and I don't want to get into a situation where I'll never be able to get it back to proper timing etc.
