Thanks Morris,...have been putting spring on frame first, next time I have the chaincase open I'll have another crack at it your way. Had the spring handy so took a couple of pics, I.D. measures ~1.115ish". Saved an Image of that tool- maybe will fab one from an old screwdriver from that.
I keep meaning to chase up that Rory Gallagher song- I saw him at the City Hall here in about '74, maybe his only visit here. I'd found a album in the square where some people had been sitting and left it, and waited a fair while to guard it until they came back but they didn't.....so I went along to the show when he came (it was weeks or months later)- thought they may have been there to give to, didn't see them so I scored a record, still have it tucked away
, but need to fix the turntable
