The chassis for 7804 is starting to come together,

The first task was soldering up the Comet bogie, this has been mounted to the body with a home made spring (which needs adjusting to provide less downforce)

Without con rods fitted (or a gearbox) the chassis is freely running up and down my test track.

Next up was the cylinder assembly, first up it was compared to the drawing in Russell which shows that as expected the Comet cylinders are missing about 1mm in height (from the top).  The holes for the castings were opened up before soldering the slide bars into place.   As ever the crosshead took a fair bit of tidying up (one day I will actually get round to using the machined Markits ones!)  It now needs the brackets soldering on before cutting off the ends to allow fitting of the cross head.

Next up will be the con rods & finding a gearbox.

I have also now got access to my detail photos of 7808, which will enable the cab detailing.
