The next step is the planetary differential.
the 45° gear are coming from www.maedler.de and deeply modified
In some case, to have a high level of precision, the gear was fixed with hard Loctite on a provisional shaft and machined in precision collets.

Now is the cylinder and cylinder head
No particular difficulties, the cylinder is coming from iron GGG60
Lot of changing position during machining process of the cylinder-head
Also, need tailor-made jig for some specific mounting
After machining, honing with Sunnen honing machine
The finishing is really exceptional, close to a mirror !!!

Amazing work Jack!

Thanks for sharing your great photos; I'm enjoying the progress on your tractor.

This is the construction of the "Pitman arm" of clutch command
Mainly handcraft job with hand-files, emery-paper and final polishing.
Less machining works.
The security hairpin is made from parts of a bicycle brake cable, so 0.4mm

The mud guard was difficult to made. Two trial before success.
At first, the binding of "L" profile in messing.
I test different possibility to do it, and at least, the best solution was heating with a blow-pipe and fold it gently on a pre-calibred aluminium disc (see on the late)
The next difficulty was the positioning of the hole for the 1mm rivets

Now the painting and some comparison with real tractor
The diagram gives:
130° for intake
100° for exhaust
100° for transfert
So, very "quiet" diagram to have torque and slow RPM
