1993 Marin Pine Mountain rebuild (hopefully)

Hezza

Old School Hero
A few months ago I was looking for a new project and my wife spotted this 93 Pine Mountain for sale, a price was agreed and collection arranged. It was getting dark when I picked up and although I could see the rust I was not unduly concerned. Sure the chain and front skewer was seized but the seat post moved and it was mostly original (handlebars and rear rim not original) so I was quiet happy with the whole thing.

However on closer examination in daylight, especially underside of the bottom bracket, I began to think I had bitten off more than I could chew and maybe this was beyond me. I had a few options as the group set was all there and cleaned up well I thought I could find a new frame and start again. At one point I considered sacrificing the frame from my 93 Eldridge Grade. I stripped measured and weighed it and couldn't find any difference between them.

I put it in the shed and tried to think about the options, in particular who I could get advice off regarding saving the frame. As it happens I know a couple of professionals who know about these things and after seeking their advice have decided to give it my best shot

Attached are some pictures of it when I started. I will hopefully provide updates as it goes along.

Does anyone know the correct spoke length for the rear wheel? If anyone does I would appreciate it if you could let me know. Mavic M231 and DX hub.
