just the cad render showing the support for the worm shaft.

parts here were cut using a wire cutter edm machine, 

the advantage of these machines is that the wire is quite fine, allowing very fine corners.

shown are the cylinder with valve chest, as well as the slide rod supports

gears were cut from mod 64 gears stock, this is available from small parts and bearings.

hello all,
a long time i know, anyhow i have started to remake the new design,
i have a number of parts i have been making in the next few post.
first picture is the wheels, i turned these in one operation, i made a tool on a wire cutter edm,
it had two points so i could cut the front and back in one set up.

hi all, i have been doing some drawings lately. I have found some better motors and gears. This will improve running.

there both 12v and allow room for a flywheel. The garratt drawing is new, it is based on the NA mech parameters. As there is starting to be more wheels here i am tempted to get them made outside by an engineering firm. The garrets drawing is not finished, but most of the overall structure is done.

hi all, more pics. this is the first coat of paint. is just so i can put the glazing in and glue on the roof.

hi all, a few more images. its starting to look like a NA now. the chimney was turned on my lathe,

as was the air compressor. handrails and pipes are various sizes of brass wire. the filler caps (i think there filler caps? ) are heads of pins.
