Making progress.
The cutting cylinder and bottom blade are de-rusted, painted, sharpened and reassembled with new reaction springs and felt seals. The old springs appear to have been attacked with an angle grinder; can't see why as the new ones are far from coil bound with the reground cylinder and refaced bottom blade.
The rear roller had spent the weekend in the diesel tank which had done its job and the roller didn't put up too much of a fight. The grooves on these roller sections are good so no tedious re-cutting required!
Chassis and grass box etc off to "blasters" for stripping and epoxy coating. Unfortunately they are busy with all sorts of interesting things so wont see them back till mid next week but there is the engine to strip and re-paint.
Might even tidy the workshop!
