Update:
My graphite piston "stock" seems to be on backorder...it is after dinner and nothing earthshaking will occur on a work night...but I was just itching to belt something up with the "bead cord" belt I welded!
I have (3) variants of Ertl Diecast scale engines and big plans to bring them to work and tune them up as engine accessories to power. The red one was by far the truest running Flywheels out of the box so I just put a couple drops of MM oil on axle and belted her up.
My little QX6 will "almost" power it on the belt pulley of the red engine but not quite...I was bummed but since I had all the stuff out I moved the grippy "bead" cord belt up to the big diameter part of the Flywheel to give my QX6 a little mechanical advantage. What a difference!! The QX6 is racing and the red Ertl is turning a pleasant speed bone stock. I thought for sure I would need a tracking groove machined for the round belt but with just small adjustment she tracks on the flat faced Red flywheel just fine. What a hoot!
