This is a plate to hold the coil pack to the frame of a top fuel dragster.

 


This is a crankshaft housing from a 2 stroke engine that powers a radio controlled car. When assembled the motor will produce approximately 15 horse power. The housing is the first of its kind - it was designed and manufactured to replace the 40 cc reed valve with a 50cc reed valve.


The image is an internal gearbox fork from a Mazda RX5. The fork on the left is the original cast item which failed. The fork on the right is 6061 billet Aluminium, to date working fine.

The leftmost bearing cup in the image was made in 1914. It held loose half-inch ball bearings against the axle of a 1914 Chevrolet. The bearing cup surface had pitted, damaged the ball bearings and no longer provided a smooth rotation.

The right bearing cup in the image was made in September 2014 and includes angled roller bearings. It has been roughly carburised to match the appearance of the original. When fitted, the new bearing cup will be indistinguishable from the old.



Body built from scratch, all steel construction.


The caliper bracket in the image on the left has been CNC machined, but has the surface texture and appearance of the forged spindle and steering arm. It was CNC machined from each side and the program was offset 0.2 mm for the second side to create a fake forge line.
