Today I welded on the bottom rock guard I made for the 78' KL 250. And I did while standing on one foot.
You need a recliner with wheels
i used to use , as i'm sure many other do, an old office chair on wheels but with the back removed. i say 'used' as one day before the most excellent hip replacement i was sitting on it doing something to a bike, tried to stand up using my one good leg for leverage and the ba$stard thing shot out from under me, dumped me on the garage floor and due to the aforementioned dodgy hip it took me a good 10 minutes to roll onto my good side, crawl across the garage and drag myself up using a bench to hold onto.
i now have a similar office chair but with a back to hold onto when levitating, having two usable legs helps too
