So today has NOT gone well and design decisions made on day 1 have come back to bite me in the bum big time.....
A throw away remark to DannyC in today's ' chew the cud ' talk ' I bet if I put a length of cable in the mech to hold it in 2nd I could ride this ' set off a train of events that have led to some very bad discovery's.
First I did shorten the screws in the pulley and removed the extra M12 nut getting it much closer to the frame an [ I though ] much improving the chain angle i.e it is now neared the middle of the cassette...
Now at the bottom this looks great however the picture reveals that all is not well at the top , I did not spot this whilst out there so have not investigated further yet.
I though if I put a better rear mech on I may even get it locked into first gear , for that I needed to improve this
Just a simple kids one held by the wheel nut [ naughty boy ]
So I hacked a frame up with the later styled hanger leaving the stays on I could see where it needed to go.
I cut free the piece I needed and trimmed it to fit , instead of welding it I decided to hold it again with the wheel nut just to see if it worked.
I though this may have been one of my better mechs a SRAM X-9 and duly fitted it.
Now I have some sage words at this point.
IF you intend using a s/h mech check that both the jockey wheels spin freely BEFORE you mount the wheel in the frame split the old chain and try to feed it through the mech !
It saves a lot of tears.
After a break and some comfort eating I tried to swap the mech for a SRAM X-5 , would you credit it it also had a jammed lower jockey wheel.
At this point I had a much newer mech that looked as though it had been barely used in a stash of parts Dale-Rider kindly donated to the cause , it's only a Shimano Tourney but looked clean. So it was duly fitted and all back together I could try it, the extra thickness of the mounting plate put the mech to far out however using all it's adjusting screw I was able to get the chain to fit comfortably on the 8th gear , so 1 more than yesterday hurrah you say , however this was short lived as when I tried to get to 1st I found the lower mech jockey wheel fouls the TYRE ??? I assume because I have a 16" wheel the mech cannot operate inside the wheel diameter , although that does sound like a recipe for disaster as there are tales of the front tyre snagging the chain and causing all sorts of problems. A shorter cage mech may mean 1st is available but safely ? do I need 7 speed ? well probably not an answer as 1st will still be in the same place ?
So I tried in vain to clamp the mech in second , that is just not possible with only 2 hands so giving up I took it outside in the hope the slope off the drive would help a start in 8th !
Now a 2 wheeler problem turned up as there is no brake it was hard to hold if whilst I got a foot on the pedals and also any attempt to pedal would cause the overlong bolt on the small pulley to carve my leg up.
A freewheel down the Close was all I achieved , I did learn with only 10" handle bars a shrug of the shoulders were enough for it to move off line about 3ft scary
Maybe it could be tried with a brake fitted and a shorter bolt so out with the parts , err NO with a capital NO !
DannyC's method of widening a front fork for a rear wheel has an unnecessary side effect ? it widens the brake posts also then the brakes no longer meet the wheel ?
I remember the shoes have 2 spacers thick and thin so I swapped them over that did mean they could reach the wheel rim however only the lower half below the wear groove in the brake surfaces and this happened at the top.
I think the best plan at the moment is to cut free the bridge from the suspension fork and weld in the same position as the existing brake mounts ?
I may be able to get it to work.
Lots of work almost no progress and still no ride..
