fuel sender adaption

As I only had a fuel sender from any other VW model - which did not work correct, I had to "fine tune" this one to get it to work properly:
First step: analyze the original (broken) sensor : 
 upper fuel level of original sender


 lower fuel level of original sender






 new sender: impossible upper level position -> electrical resistor indicating "full"



new sender -> resistor reading "empty" - but impossible lower level position - much lower then lowest possible position in the tank




 direct comparison: upper float level on old vs. new sender



 direct comparison: lower level on old vs. new sender



 check of floating behavior of old sender



  check of floating behavior of new sender

 The only solution: modify the lever arm to
-meet the full and empty resistor positions
- meet the full and empty float levers as well!
 after some "fine calibration": same lower float level of old and new sender unit


 Also: same upper float level of old and new sender unit


strange looks - but works fine throughout the whole range from "full" to "empty"

crankshaft clearance test

before the engine case will get machined + align bored, I wanted to check the clearance for the 78,8mm crankshaft:


no issues - the crank fits without any rework to the case!

a visit @ a friend

my little side project is getting started. First step was to clean the old cart wheels from the real bad paint - who else would be better for that Job than Jens Kraft - the Master Blaster himself ;-)
 this what I started with, a set of used bambini cart rims

 awaiting the treatment...

 the first weapon of choice is the big nozzle

 professional @ work - thumps up!  What you can't see - It is f*cking cold in the work shop

 a little glass blasting action for a finer surface

looking much better now - at least one rim (lower left) needs some "fine calibration" before  I can move on...
If you are looking for professional, fast and affordable workmanship - look no further, ask Jens: /http://www.sandstrahltechnik-kraft.de/

damned chrome plater! (no pic today...)

Last week I 've been at a local chrome plater for a quote to rechrome my rear bumper. The guy told me around 350 - 400 €uro + tax.
Today I've been there again, to give him the bumper - when I asked again he claimed at least 500- 550 €uro + tax! Fuck him! I was about to shove my bumper up his a....
Anyway, I still don't have a nice rear bumper . If anybody has a clue or a honest chrome plater - let me know!
