I knew there was a reason for oil fed bearings.:D
In some ways it doesn't seem too mad.
Except, drive flanges are pretty cheap and easy to fit - heaps quicker, I'd guess, than a thorough welding job.
The fella didn't just tack weld them on the side of the road to get himself out of trouble, he went the whole way, nice deep, all-the-way-round welds.
Cheers
