To machine the wheels on the Myford the head needs to be raised as does the tool post, so this is my home built solution. The drive is a Morse tapered shaft fitting into the head stock held in place with a locking rod. The drive is via a toothed belt giving a reduction of 1.6:1. The headstock bearings are, a tapered roller bearing in front and a plain bush bearing at the rear with a thrust bearing at the back to preload the tapered roller bearing. All assemblies are bolted together and made from 1/2"aluminium plate bought from the scrap yard The tool post top is thicker as it has to accommodate the locking screws for the tool post slide.
		The differential gears for the rear axle are machined bevel gears. They are produced by adjusting the work presented to the cutter to achieve the bevel so that the tooth form is on a radial from the gear tooth centre. The drive to the rear axle is chain so the differential centre is a chain sprocket.
Machining a pinion and crown wheel for the differential
So far so good - the differential is finished and now sits in its spun housing on the axle. The rear wheels have been machined and their brake drums, they are now keyed onto the axle. The next task to complete the rear wheel set up, is to do the brake shoes and cam brake operating mechanism.
		The front wheels have also been machined and mounted on their stub axles together with their retaining collars and hubcaps ...... which means I now have a rolling chassis (except for the tyres on the wheels!)
The component parts to make a brake arm
		The band brake stanchion and operating hand wheel and mechanism. This pulls a wire rope connected to the band brake lever over the rear axle.
The assembly of the rear brake, its operating rods and foot pedal.
