HSP parts printed

Parts are coming together.  half scale flipper bats (added a groove where I intend to use an o-ring for flipper rubber).  Screw taps into a flat on the shaft.  There's coil arms above that.  The black piece is a fixture to hold the dowel pin while I manually grind a flat with a bench grinder.  If it works out well, I'll probably just farm it out to an online CNC company but I want to test it out before I commit to ordering a higher quantity of shafts to get a decent price break.  The shaft bushings are 3d printed (fit is good).  One blue coil came today (I ordered a pair, but had to order them separate because amazon does that weird thing where if you order at the same time it gets delayed a week).


I'm 3d printing a chunk of the playfield to test.  I know I could just drill a couple holes in a piece of plywood but I don't have a home depot close by (and I just want to do a quick test).
