Bunk or roller trailer

[rhody98]

On the set up there are 7 12in Stoltz rollers and
8 4in donut rollers. I used 14in galvanized 5/8 bolts on the 12in rollers and 4in 5/8 bolts on the 4in donuts.
Every shaft was drilled in the center of the bolt head approx. 5 inches on the 12's and 2 inches on the 4's
with an 1/8 inch dill bit, with an outlet hole and the end of the drilling. Then tapped for a zirc fitting that
enables you to be able to pump grease into the roller shaft.

This is an excellent idea from NoBones, good pics. Wish I saw this thread before I bought the standard 5/8" straight shafts with "hat" caps and new 8" keel rollers for my trailer. Pretty much have to take it apart to regrease. Next time, I guess.
