Hi Programmer,
As Scott mentioned, in mechanical circles, such a 'collar' is referred to as a 'bush'.
Typically they are manufactured in materials such as bronze. Some come with
a flange.
The Az pivot bolt is 1/2" in diameter. You can find bronze bushes with 1/2" I.D.
that then come in various O.D. and lengths. For example, you might use one with
an O.D. of 3/4" and then the appropriate length to feed through the base of the
rocker. Drop me a line at
sales@wildcard-innovations.com.au for a lead
on a supplier in Sydney where you might find something suitable.
If you have a power drill, you then might consider borrowing or investing in
a hole saw with appropriate O.D. A jig for the drill so that you can cut the hole
exactly at right angles to the inside surface the of the rocker is highly recommend.
You also want to take care in centering the hole as best you can.
Adding a bush to the Az bearing will not only reduce chipping, wear and tear
and reduce wobble, the movement of the Az bearing can also be made to be
considerably smoother.
Best Regards
