Ehsan, hes saying at the least, bore a hole straight into the larger cylinder at the point of the ball bearing and put a grease fitting in there, that way it wil work its way down the inner shaft as you grease it.

FYI: most guys are using a trailer spindle and wheel bearings. That way they are serviceable, and you can tighten them up after they get bounced around a while, and loosen up. Heres a link.

The Rockstomper spindle is a little weak...............a Slee Offroad spindle is much stouter.
 
so did you make either one an air reservoir?
 
Nice work.
I like the spindle down approach.

How do you grease it? And won't the grease lift the pin.

Looks great but you have to get back to making my top.:grinpimp:

There is a nipple from where grease can be pushed in using a grease gun. This hinge is very nicely made. Even without grease, taking the two parts of the hinge apart takes a considerable force due to air locked in.

PS.. Oh.. Your top is almost done. :)
