Thanks Pat, It has not been an easy ride for sure having made 3 rear casings and two front so I have to be careful how I work on this...

Today I managed to squeeze a three hour session in the workshop and managed to bore out the cylinder mounts which was very tedious...

Thanks Peter. I did my best to achieve that using a snug fitting dowel rod from the spindle nose. I don't have sophisticated measuring...

Hi Ollie, Thanks for the kind comments but I think it looks better in the photos than in the eye :) This is not quite a radial but a...

Next challenge was casting the rear case which was the afternoons task. The first attempt showed bad shrinkage at the cylinder mounts...

Today was started with my first problem. I clocked up the bore on the mill as datum for drilling the eight crankcase bolt holes and on...

The crankcase half was clamped on the mill bed and a pilot bore made through the nose of the casting and its face squared off. The case...
