I thought I'd give the Standard Porter a go after redoing the joints on the steam line, which went okay. But it went down hill from there....
The first issue, is the spring for the piston is missing. I tried to use a spring I had and it kind of worked but then it jammed up because the spring was way too small but it did run for a bit! Then I had a bit of a calamity, the rudder fell off! Best that I could tell it was just glued on from the factory. I cleaned it up and soldered it on. I am thinking what I should do about the solder joint, the shinny solder sticks out like a sore thumb - grrr.
So I bought a Compression Springs Assortment Kit that has 4mm~6mm OD springs in the kit. Hopefully one of them will get it going properly!
