Almost finished my latest project (after nearly 3 months with no 'shop time!) so though I'd post some pics. I know that this was a group build before so many will be sick of the sight of this little engine but here goes.
As I don't have a milling machine I simplified some of the parts and used whatever suitable was to hand for materials. I also converted the dimensions to metric to suit my kit. The shaft is a bit bigger than on the plans (i.e. 6mm) so I had to adjust the hole spacing on the valve face to suit.
The bearing is turned/sawn/filed from a lump of cast iron (didn't have a big enough chunk of brass).
The valve is built up from two discs of brass, the lower having the two 1.5mm slots made by careful chain drilling/filing then silver-soldering to the upper.
I extended the steam connection so I could use pipework unions to try it on steam ;D
Still to do:
Find/make grub screw for crank disc
Solder pipe at cylinder end
Make handle for valve
Polish out all those machine tool 'scars' and soldering stains!
