Rebirth of a 6 Foot Flail Mower

You'd be amazed how often you wash your hands slicing and vacuum packing bacon :bugeye:
The slightest bit of bacon fat stops the heat sealing working, and handling a chilled flitch of bacon through the slicer certainly gets you cold and slippery :lol:
Planning and work flow are the keys to sucess, and a good scrub down of the stainless steel work top afterwards :thumbup:

Hi Andrew,
Would ye not put a few packs in the "for sale section"
:mmr:
awemawson:
They'd not arrive frozen Will :scratch:
So this morning I prettied up the gearbox. First a coat of primer having washed it down well with thinners. Then while that was hardening I re-made the adjuster for the belt tensioner, as the thread on it was badly mangled - just a bit of M20 studding that compresses a spring. The idea is that the spring is compressed fully to allow the belts to slip on, then the threaded rod is slackened off letting the spring bear on the side of the jack shaft pivot putting belt tension on.
Then back to the gear box for a coat of top coat (RAL 1007 JCB Yellow)

Now talking of belts - there is an oddity :bugeye:
The four sheave 200 mm o/d pulleys are marked SPB - which is a Vee belt shape specification (16.3 mm wide and 13 mm thick) Of the four belts that came with the machine, three are marked 'Turner' (the maker of the flail) but measure as 13 mm wide and 15 mm thick so are not 'SPB' belts. The fourth belt is a Trellborg and seems to be marked SPB 1600 but measures roughly the same as the other three. Also there is evidence that the belts have been bottoming on the sheave grooves as they are shiny.
I suppose that it's possible that all the belts started off correct width and have worn uniformly over the years, but that seems a bit fanciful frankly :scratch:
I'll probably assemble it with these belts and then measure up to see a true o/d to allow me to find a proper 'SPB' Vee belt set to fit.

I wanted to bring the newly painted gear box into the heated part of the workshop for final paint harderning, and decided the safest place to put it was back on the flail as horizontal surfaces all seem to have disappeared :thumbup:
