HO Truck Bolster Clearance Hole

Brian Leppert <b.leppert@...>

I would like to get opinions from this group on what do you think is
the optimum HO truck bolster clearance hole for mounting the truck to
the car.

NMRA's RP-23 calls for a .089 diameter hole to clear #2 screws. Only a
few manufacturers follow this. Most have a hole larger than 1/8 inch.

It seems to me that the smaller hole would be best for resin kits. But
would it also be OK for plastic cars?

Tahoe Model Works currently has a clearance hole about .120" diameter.
Has anyone been happy with it? I'm willing to change it.
