With the axle horizontal to the ground (and after the Jig application), put a single drop of oil (straight from its original packaging) on the inner journal (e.g. the one closest to the nail point). The drop size really is not adjustable. Rotate the axle so the oil coats the journal evenly. Tip the axle head down and allow the drop to flow to the journal closest to the nail head. With the axle horizontal to the ground, rotate the axle so the oil coats the journal evenly. Lastly, tip the axle head down, spin the axle, and ensure the oil coats the nail head. IMPORTANT: Shake off the excess oil and you are good to go.
Its simple really.[/QU
Don't overthink it... couple drops right where the wheel rides, let the excess fall on the carpet and install the axle into the wheel.
I tend to do that.... Thanks
