Onto the first motion parts, I had planned at this stage to start stripping the frames down ready for paint but when reading a fellow model engineers update in regards

Something that needs doing now before moving on much more with the chassis assembly is to make the sander rear mounting plates and drill/tap their mounting holes before painting

All of the crank-pins have raised steps that sit flush with the wheel boss at 19/32nd diameter so each started off as a piece of silver steel at that
