Yeah, i think i had a few better days now

...and thanks for taking us along for the build

No problem, i like build reports with many pictures very much, so i take a lot of pictures by myself, when i build something

Today, I started on the main con rod:

The rough stock mounted on the rotary table, drilled and reamed:

Cool, always great when you get home to find a surprise.
So......., what are you gonna do with the aluminum and stuff next to it? :big:

If your going to playing with the items on the left....go easy with the stuff on the right.... ;D

Back again,

I feel a bit foolish, as i wasted most of the aluminum i ordered...but i managed to finish (almost...) the cooling jackets for the zylinders:

They started live as blanks with 65mm diameter

Turned down to length and bored out:

Made a mandrel to perform the jobs on the outer diameter:

Milling the contour of the flange:

[Metal Mickey]

Superb work :bow: :bow: :bow: I only ever 'resize' my materials..........waiting in a box for a future use.....

 

[stefang]

Arr, nearly finished the engine housing:

Boring the cylinder ports:

Drilling the mounting holes using a template:

This is the 4. attempt in building the housing, the other three went into my resize bin (i'm learning )
