Rebirth of a 6 Foot Flail Mower
awemawson:
So this afternoon I made a new locking nut / bearing adjusting collar. Turned out ok :thumbup:
The curious 'upstand' of reduced diameter is actually a form of locking washer attached to the nut bit. It is punched down into a recess in the shaft in two places to stop the nut unscrewing.
awemawson:
So at long last the bearings and seals for the gear box have arrived so I'm glad to report that that is back together, and even filled with fresh Hypoy 90 gear oil. :thumbup:
So now to get on fixing the tubular 3 point hitch frame with a break and a bend :bang: I decided that the easiest thing to do was to cut it apart, insert a tight fitting bar up the tube, and weld it back together. There is an angle iron stretching across the width that must have been hit by the PTO shaft as it is well bent and also needs replacing.
First thing - cut it apart
awemawson:
Now this is substantial 60 mm o/d tube with a 5 mm wall, and as luck would have it I have some lengths of 50 mm EN8 solid bar which is a nice sliding fit. So the plan is to slide a bit of this bar across the pipe join, weld it in with plug welds through drilled holes, then weld the chamfered end of the pipe back together.
awemawson:
The forecast was reasonable for today - or at least more reasonable than the rest of the week so I thought I'd try and grit blast and spray the various components. We're off for a few days holiday at the end of the week and I was keen for painting to happen before then so it can be hardening off whilst I'm incarcerated in a Motor Home :scratch:
It's always a big bind dragging out the blasting kit so I really wanted to get it all done in one session, but doing the main chassis took ages (and seven bags of crushed glass!) so I cut my losses and confined myself to just getting the chassis done.
Started as the sun came up and had got the etch primer on by 12:30 - still rather overcast but after lunch the sun broke though and the chassis was actually warm to the touch, allowing a coat of top coat to go on.
awemawson:
So I still have this pallet full of bits and pieces which will probably have to wait for my return from our brief time away, as I've lost the will to live when it comes to blasting :bugeye:
