We recently painted a building using some paint Dad had picked up god knows when, thought it was great until 48hrs later when trying to give it a second coat because the erectors were coming, it still wasn't dry and worse than that the second coat pulled the first off and also mixed in with the primer underneath.... Always use new paint
I have had this problem but it wasn't to do with the age of the paint in my case - the 'new layer' was made with a different type of solvent, it dissolved the underneath layers, it may have even needed a hardener like araldite.
 
We use a mobile mechanic here for voluntary periodic checks on our vans (similar to the six weekly operators licence checks)

Got fed up with having to go a mile down the road to the workshop to drill the odd large hole with the big pillar drill, while having a mag drill sitting on the shelf doing nothing 99% of the time. So decided to make a mag drill stand out of an old (and non-functioning) pillar drill. Managed to free up the table so it moves up and down and swings side to side and the vice swivels too, so hopefully will be able drill most things.

This is what happens when you let stock farmers operate machinery

It's the drive end of a Kuhn topper flail shaft. The narrow bit is where the bearing used to be before it exploded. As you can see, the failure was not noticed immediately. Or even very soon afterwards.
This is the side plate onto which the bearing was mounted

The hole in the middle should be round. :facepalm: :cry:

Quick application of some Pickhill Bantam, and a little Makita, got us to here:

So far, so bodgey. But I thought I'd try my hand at being a proper old fashioned fitter. Say hello to my little friends: barsteward, second and smooth.

At 14 inches, they're not all that little though.

Some time later....

There are some hollow bits where I didn't lay down enough weld, but I think it should be alright. It's a spherical bearing, so the shaft is not subject to any bending stress at that point, just the torsion from the belt drives. Fatigue may kill it eventually, but the machine is already 25 yrs old, so I expect something else will kill it first.

The bearing is a good sliding fit. Engineer's blue reveals the odd high spot, but it's surprisingly round. All together, I'm chuffed to bits with the repair.

Tomorrow's job is to get it all back together!

Just a word of warning, I did the same on a combine rotor shaft once where a bearing had run the shaft, built it up with the welder & back down with the grinder, last field of the season the shaft snapped, hope you don't suffer the same.

I can remember being told of a shaft on a threshing mill that snapped and was then welded, to prevent localised stress the whole shaft was heated in the forge then cooled, never gave any bother again.

Will absolutely be stealing this idea, thanks.

I'll change it a bit to avoid obvious patent infringement 😁

HSENI names new farm safety champions

Written by William Kellett from Agriland

Farm-safety-640x360.png
The Health and Safety Executive for Northern Ireland (HSENI) alongside the Farm Safety Partnership (FSP), has named new farm safety champions and commended the outstanding work on farm safety that has been carried out in the farming community in the last 20 years.

Two of these champions are Malcom Downey, retired principal inspector for the Agri/Food team in HSENI and Harry Sinclair, current chair of the Farm Safety Partnership and former president of the Ulster Farmers’ Union (UFU).

Improving farm safety is the key aim of HSENI’s and the FSP’s work and...
