Hi Jeroen; Have built this kit myself & I found the standard had a chilled skin around the cylinder flange so keep an eye out for it. I had some probs with the crankshaft initially but nothing that couldn't' be overcome, the other bit that you will have to take care is where the bearing blocks fit I used a ball end cutter to keep the radius as true as possible. Machining the feet of the standard takes some setting up but with a bit of ingenuity can be done simply, I made a aluminium faceplate to machine the cylinder flange then found it was better to set the standard up in the mill, using the cylinder flange as a ref. & machine the feet that way thus keeping the feet parallel to the cyl. Flange. Another problem I found was that the cylinder bore was some way out of concentricity in the casting... bad casting in the kit, so had to eyeball set up as near as dammit to run evenly.
Some pics of the machining... there are more in my album in MEW forum... http://www.model-engineer.co.uk/forums/postings.asp?th=123558 'Mechman48'.
Plus a video of completed engine running.

Thanks. I've recently read through homews, but I don't recall a piece on the bearings. I'll look again.
I did just figure out a mounting for my Starrett "Last Word" on the Sherline lathe. I was able to do a reasonable job on the two bosses of the steam chest. Should work out for the main bearings as well.
The parts for the 10H and 10V are very close.
Edit: That helps! Use a 3-jaw chuck with packing instead of a 4-jaw check for the bearings.
