Partway through cutting edge repairs



End bits rebuilt with what we refer to as "hockey sticks".  Welded on with 16TC rods (which I think are your 7016 type).  So far so good as we don't do a lot of rock work.



Things you find out of sight.  I'm guessing the rod was shortened and rethreaded and too short so that was the stop.  Except they have over-travel stop valves that didn't touch - didn't work either as they'd been put in backwards and squashed.



The quick drop valve assemblies had migrated to the down-bar bow at 90 degrees to what they should have been.  Only after they went back here did I find what "quick drop" really was!

And one of the real joys was finding that the blade cylinder pivot shafts had been turned down 20 mm and fitted with some strange bush that was on hand.  And the outers had also been oversized.  It IS possible to build up that much and lathe off.  Our 1935 vintage lathe wasn't so good for machining  the outers so

Precision machining. Hell Ian, what did the wife think about you rebuilding the cylinders on the bed?

Hmm - that precision grinder attachment might just work on some projects I have -

Shameless

They must have been there as the rough welding disappeared eventually and it came back to the required diameter.   Feed was in thousandths so it was a patient job that took several nights. 

They would have stopped for the photo.  I didn't have power feed then and it doesn't have a stop either so it was all by hand.   In similar vein - a weather station I visited had for its radar set until recently one that came out of a 1942 UK warship that still used the original cavity magnetron.  Everything done by hand.  Rueful comment was that you learned everything needed about using a radar set.

It is back to using the standard Fiat bushes - not that I'm likely to wear this lot out unless a much better long-life pill comes around.
