David Andrews Princess – Crank Pin Nuts

The last few days have been one step forward and two steps back…

The wheels have been drilled 8BA as the guy that I am building it for prefers the thicker material.

I didn’t have any steel 8BA screws so I turned some rod down and threaded it 8BA. Next on auto pilot I made some 8BA crankpin nuts.

Then of course I did what I should have done first and looked at photos…

So far I have made a pair for the rear.

I have also made some rear plates for the balance weights but I haven’t taken any photos yet.
