So the other day, I stood the push bike up on its prop stand, and it then promptly fell over.
A quick inspection of the stand showed it sporting a rather acute angle in the lower bit of its stand. Looks like metal fatigue finally got to it after one too many straightening attempts! (it is a fairly skimpy stand and quite a heavy bike)
The top section is an Ali tube, and the lower bit a 3/8" steel tube that slides into the top bit where it is retained with a small machine screw. Since the broken bit was steel, I thought that there might be scope for a repair.
So before splashing out another £7 for one from Amazon, I thought I would see if it could be repaired,,, All I needed was to find a bit of metal bar that I could stuff into the broken bits of tube to splint them together.
Ladderax the rescue
SWMBO had acquired some genuine '60 Ladderax from her dad, and a couple of weeks ago had asked if I could shorten some of the uprights so that they could be used close to a section of vaulted ceiling. So I chopped the top bit off a couple of them, remove section and then welded to top section back on...
I still had the offcuts laying about in the workshop and so wondered if one of the spare "rung" bars would work as a "splint" for the broken tube?
The diameter was a little too large, however chucking up a bit in the drill and working up and down it with a flap disc in the angle grinder soon sorted that.
So I straightened and cleaned up the broken bits of tube, and then hammered the splint into one end. Cut off the bar leave a bit exposed, Tapered the end of that and fitted the other bit of stand. Gave that the same spinning flap disc treatment and had something ready to weld up.
A few fillets of weld later, and then another clean up with the flap disc, and we are back in business.
