Quoted from Mad_Dog_Coin_Op:Does anyone know what post size to use where? Classic Sterns seem to always use tall posts for the lower two / thirds of the playfield. Any post under a plastic in this area is tall. The upper third always seem to be the shorter posts. That logic doesn’t seem to apply to Star Gazer. What I am seeing in restored machines is all posts under a plastic are tall with only a few exposed posts being the shorter ones. Any help is greatly appreciated.
I put tall posts on my slingshots.
For drop target plastics I use short posts; there is enough clearance that the plastics and drop targets do not interfere with each others. For arch plastics I use short posts so they will nest against the ball guides and prevent light leaks from the GI lights.
On the SG I built, IIRC, since there were no slingshots, I think I used short posts everywhere. I may have used tall posts at the spinners, but can't remember. However, with the Quicksilver I am building, I used tall posts at the spinners and had to swap to short posts because the play field glass could not clear the two spinner cages.
