I was cracking on quite nicely with the chassis but when I got to the next phase of the instructions I found one of the castings missing.

This is the offending article, there should be one at each side.

After umming and ahhing as to what to do I decided it would be simpler to scratch another than to wait for the owner to source one from Tower/DJH.

Poor photo  but this is it made from scrap etch and some wire filed half round.

Last night saw me make up the coupling rods which all went swimmingly until I got to pinning them together at the joint. The instructions have you tapping one side 12ba to screw a cast threaded pin into. Having done the first side I quickly realised that the thread on the pin is way smaller than 12 ba Bah!! 

The other side I tapped 14ba and I ran a 14ba die down the cast thread,  I screwed it into the tapped hole and the threaded section promptly broke off in the hole Tonights task is to solder the pins into the back of the hole as I would have done with a rivet of Premier Rods. Onwards and Upwards…..
