Although it's possible to do milling on the lathe it requires a  lot more effort and patience (and time)to achieve good results, and after slotting a couple of cylinder heads and woodruff keys in a new counter shaft for the myford, I  brought a  mill ! 

Some more metal mangling

So I have managed a few 20-30 second burst after a lot of flipping mostly due to the fact I made the piston/liner quite tight, I think most of the running in has been done by hand  lol 😆! I may have to  reduce the piston skirt by aro 20-30 thou as there's very little sp induction and a new needle valve as the one I'm using is of a K Mills. 

So time to resurrect another project

Well I'm having a bit of a issue with a tight spot with the Speary piston/liner I think I will have to get a bit more aggressive with the lapping, most likely need another piston making 😒

But l have finally got some sustained running with this .

Running on a 10x4 Kavan ,when it's done a bit more running I will check the rpm's

Thanks for posting those pictures, i I tried to combine the looks of the Allouchery and the Dyno with the porting of the Mills,although I made the piston a bit long so there's no sub piston induction at the moment. I have another set of castings for the Speary that I intend to-do as an spark ignition and a set for a Atom 111 that may get the diesel treatment !
