New paint & sponsor’s logos going on.

Using paper stencils for the smaller stuff and tracing around a projected image for the nose cone.

Widened seat in position, view over the nose.

The steering bars got dished by another 3” to make it a bit more comfortable to drive.

Extended calliper fixed in position. Used ex-BMX pegs as brackets. They fix to the aluminium angle body frame with a single M10 bolt done up very tight. This allows a bit of adjustment of position and pivot angle relative to the wheel. Ground a flat on the top edge to allow the calliper to fit snugly. View high resolution

Wheel located on new axle

Pair of M3 screws in threaded holes in the axle prevent axial movement.

Located the new axle about 5” further back to improve the aesthetics mainly, but also to improve weight distribution slightly.

A bit of extra chain was spliced in. The axle runs in these DIY pillow blocks, one each side and a wider one in the middle. Each has two of the same size ball races as in the non-driven wheel.

The driven wheel was simply welded to the axle. As this year’s course is anti-clockwise, the right hand wheel is driven. Drive can be switched by withdrawing the axle from one side of the car and flipping it over (and reversing the tyres on the rims).

New rear wheel. Removed the thread for the free wheel mechanism with the angle grinder and saved it for later. Replaced it with a short length of 32mm bore tube ready to accept a ball race. Did the same on the opposite side.

We were given this really nice go kart seat. After fitting and training with it a little, it became apparent it was a couple of inches too narrow.

Sheet steel is cut from an old PC case. Fastened with long pop rivets.
