Castor correcting a flipped axle
I've flipped the axles upside down, as I'm running a mid-engine. The castor is built into the axle, so it goes from negative to positive when flipped. To get some castor back was desirable for some self-centering in the steering
 |
Set the axle up in the band saw, squared off the bed of the
saw. The cut was centred on the original weld. This took just a few minutes to get right and was double checked. |
 |
Here are the ends cut off. The double wall construction was
just visible here. Ends were labelled long + short, anything else was just too confusing. This was cut down the centre of the original weld - that's a good weld. |
 |
This 'jig' was made up out off an off-cut from the front torque tube, it was machined to be a sliding fit in the axle tube. |
 |
The axle was squared up on a flat welding bench on v-bench
so we could get it square and measure datum's. Mounts for the 4-link also just about to get welded.

Here you can see the rotation compared to the inner
brackets. The welding was a TIG root weld, capped by MIG. Just for completeness the inner tube was TIG fuse welded |
 |
Here is a close-up before paint. The new weld looks just as good as the impeccable German original. |
