If that is the only thing wrong with the cylinder I would fix and run it or possibly even run it as is. I grew up on a farm and there was very little that could not get fixed with a little ingenuity.

Measure the ID and compare to the other cyl if the offset one is big, machine round it and sleave it drill and pin it on the thicker side in two spots. I would stay away from any welding, except a a good spray welder but ther few and far between thewres alot of hacks out there with spray weld set ups.

Hey Jerry, maybe the local Amish blacksmith can do something with it :idea: , if not, 44d 's idea should at least give it more support, thanks, Tim

i really think you can run this cylinder without problems !!!

if the ex.port breacks ( one day ) here will be the time to repair it .
for the moment : this cylinder i "good for service" .

I agree with MB, however check to see if any exhaust pipe angles are going to be changed or similar due to the off-centre whatever-it-is that's going on there, as it may affect bracketry etc depending on severity! Perhaps go easy on tightening the clamp, and shim/sleeve the spigot if required?

The rest of it looks pretty good IMO - worth hanging on to at least until you find your "welder/machinist extraordinaire" guy.
