Mounting a Tractor Hedge Flail
awemawson:
Quick trial fit - yes they look about right !
awemawson:
Next to cut up the various heavy angles and plates for the tank brackets. The angle is 75 x 75 x 10 mm and the plates are 80x12 and 130x12.
Got them all cut up on the Pedrazzoli chop saw, was just cutting the last cut of the last piece, and there was a 'ping' followed by the clatter of something dropping to the floor :bugeye:
The balance spring that holds the chop saw up had broken at one of it's hook loops. This is a beefy spring wound from 6 mm wire with twenty turns on a 35 mm major diameter with hook loops both ends.
.... go on empty your pockets, some one must have one :ddb:
I think the next job is to cut the slots for the 'jaw plates' which seem to be a nominal 20 mm thick. If I have a suitable broaching cutter for my magnetic drill I'll drill holes for the ends of the slots and cut the rest with an angle grinder.
It's probably safest to then weld on all the various brackets, and drill the holes after welding to get them in the right places :ddb: One of the plates is slotted, so that will probably be done on the Bridgeport
awemawson:
Chap has just delivered the plumbing bits to allow the pump to be removed without loosing too much oil. I'm using gate valves to give full bore flow, but they will need a bung as they are prone to weep a bit.
This means I can put all the oil back in the tank when I get a spare moment
chipenter:
You can get large ball valves with handles that give you full bore .
awemawson:
Jeff - yes I've got some in 1" - I was tempted but these gate valves are nice and chunky solid.
So I dug out the Magnetic Drill from it's crate I made 7 years ago when we moved here - not sure I've actually used it in that time. I'd forgotten what a joy it is to use
