Dean, Ross.
Thanks Chaps! Much appreciated.......
Well..... Here we go, again!
I drilled the crankpin holes.......
Luckily the assembly stayed temporarily pressed together, to allow a test run.
Assembled, with a pair of spare Mamod flywheels........
Fitted a new "wonderwick".
Fired up.
And it
still wouldn't run. Again!
What's wrong with the thing???
Everything's been checked/ re done!! Hasn't it??
Took off the hot cap. Sucked...... Hard...... It stuck to me tongue....... Nothing wrong with it!!!
Until, I poked a finger inside........
The wall thickness is around 9thou'. The end cap is 4thou', "tin"...........
I guess it was acting as a one way valve!
Sheesh!!
Sigh........
Nothing else to do, but make another, more robust cap.
Couldn't find any 1"od tube in the bits tub.
Mrs Drillin's exercise bike, now has a shorter saddle stem. (From inside the frame tube). Hope nobody tells her......
Topped to 24mm+. Bored to 23mm.........
Friction turned an end cap........
Couple of thou' under bore size.........
Silver soldered together........
Cleaned up, quite nicely........
I'm starting to worry about me. I don't get upset any more. I just expect things to go wrong........
And they do. Regularly!
Machining a new, thicker flange, tomorrow. Probably!
