After reading all treads about the Hodgson-9 I could not resist to try building one to.
I have only built to engines before ,my Hoglet and the inline 6 so maybe not the best choise of build but I need challenge
I started with the cylinders but get trouble with the finning so I put them aside for a while dont want to stuff up more than one of 11.
I went ahead with the crancase instead. Bought a pice of 7075 a bit longer then needed to take a drawbar in the end, was afraid to only
hold that big chunk in 1/2" grip.
I turned all the inside and outside in that setup like I read on another builders site.
It was a bit tricky inside but all went well and I got the right dimensions.
At last I cut it off but left 2mm that I cut off with a hacksaw.
The leftover was turned to a good fit to to have on my rotarytable later.
Cheers Ove
