pegasus/DannyC
many thanks for the advice , when I looked into it I decided that I could not even tell if it was titanium and welding was certainly out of the question.....
Sadly after haranguing DannyC for 30 minutes this morning the application of ' more thought ' came up with a different solution
However I am getting ahead of myself ?
It is impossible to see what is happening due to the body work so set about cutting the rear off and disassemble where possible in a non destructive way as possible. It was not till I started I realised how aero the shape was when you consider it is made out of only 4 basic panels.
Above sides marked for surgery , it was suggested that I make the rear end plug in for racing and a Kammback for bumbling around town , so parts need to be liberated with as little damage as possible ?
Once both sides were cut I could free the turtle deck and we are in business , I had to do this because what I discovered was if you laid it on it's side the chain de-railed anyway due to lack of tension from the rear mech [ not surprising as there are now nearly 3 full chains in it ] and the use of toothed chain guides instead of pulleys with large diameter walls which may have prevented it ?
I then made up a crude chain keeper for the front pair of sprockets , purely by accident I got it to big so the space under the chains was big enough for them to de-rail DOH !!
Then I took it for a spin and realised something had happened due to the increase in noise
This is the rear pair of sprockets the chain still around the sprocket is the drive side chain , however look where the return side of the chain is now ! it was behind the drive side when I set off.
So another keeper was made and the surplus space underneath them was packed out with some cheap plywood screwed to the bracket , quick spin and it stayed on yeah , however venturing further showed it was much to high geared for around where I live.
It appears to be a 10 speed however only 28T - 12T with a 52T ring up front this gives :-
Now I really need around 20 GI for around here , especially as the pedal car is heavier than the Python.
So next up need to change the front ring maybe 42T or perhaps a 34T would work well , looks like time to get the spares box out for a rummage.
A good afternoons work me thinks especially as it is not really the best weather for working outside , it is approaching 0c again !
