This is another item that I designed to help with my modelling. Over the years I have become frustrated with the type of rocking W-iron that uses a “tab and slot” method of fixing the rocking part to the pivot on the baseplate. Whilst I’m sure it is possible to make these work perfectly, I either twisted the tabs too much and locked the thing solid, or left them so loose that the axle could twist with all of the problems for smooth running that causes.
So I set out to design a simple etch to enable these W-irons to pivot freely but securely on a centre point. I did this by making a new baseplate. This replaces the twisted brass tabs with a robust nickel silver rod which runs from side to side.
