Problem - Knackered BB on the singlespeed. Problem - Too tight to buy new BB/bearings. Solution - Remove cranks and BB. Turn bike around on stand to get non-drive side off. Raid the parts box. Hmmm, no HTII BB's. Square taper or Octalink? Octalink cranks much lighter so decision made. Half fit BB. Find old BB tool. Find other half of BB in parts box. Finish fitting. Swap rings and bash to Octalink cranks. Middle ring from HTII cranks doesn't fit older cranks. Back to the parts box. Fit older middle ring. Fit to bike. Bugger. Miss-counted the splines on the BB, its got 10 not 8 so its an ISIS BB. Back to parts box. No sign of the Octalink BB. Find Bonty cranks, double check they are ISIS. Swap ring and bash to Bonty cranks. Crank bolts incorrect size, they must be for Octa BB. Find correct bolt in parts box. Getting impatient, fit cranks. Remember I turned the bike around on the stand?... Go to fit chain. Crap. Put driveside crank on non-drive side! Doh! Find old ISIS crank remover. Remove cranks. Bit tight. Continue swinging on the remover until it won't budge any more...cranks still not budging. Remember the remover does Octa and ISIS and there is a tiny top hat bit in toolbox to convert it. Remove tool, and as I suspected, I have tapped three whole turns of thread onto the pin whilst forcing it into the BB crank bolt threads. Refit crank bolt to check threads are OK. Fit top hat bit so pin doesn't go into threads and remove cranks properly. Re-install correct way. Turn bike round again. Fit chain. Dark now. Lock bike up and cross fingers that the 'older' chain ring isn't too worn. (its a singlespeed...as long as the chainring has pointy bits it'll be fine, right?) Throw parts box into corner and retreat back into house. Stupid non-standard standards. Advice, throw away all your spares that aren't either square taper or whatever is currently on your bike! |

Sound like a job for the extra large club hammer to me, that is a universal standard... Bearing in mind that tonight I spent about thirty minutes this evening trying to take a 12 year old wall mounted shelf unit down and resorted to some "gentle" large hammer persuasion for ten minutes until I realised that it was still attached to the wall by 3 very big screws ( all hidden as they were painted over of course) so I feel well qualified in the precision engineering field. Ok, a big hammer and some choice expletives. And maybe an oxy/acetylene cutter. Or get Hobbz to ride into it.

If this was a combat situation, we'd be dead by now.

LOL I thought I was the only one who does stuff like that I get a strange pleasure out of recycling broken parts to make a working one even though deep down I know I'm going to wind up buying a new one latter any way |
