[quote=Edchris177][quote=charlescarlis]BTW, I just changed the needle bearings in mine with some ultra-slippery, hard rod from McMaster-Carr. Seems a LOT smoother. I'll see if I can get stock number from order..[/quote]
Here is an an album I made a few years ago, everything you need to know about CatTraxx.
The bearings are really easy to make.

McMaster Carr sells the rod stock, for $5.50 for a 5’ length. You would need 4 of them, (almost 17’ required, & you’d have to allow for cutting loss), so about $22 + shipping.

Florida Sailcraft sells them, enough for both wheels, already cut, for $38. The $16 difference makes cutting hardly worthwhile.

Personally, I would not order rod stock of super hard, long wearing material, especially if using on a beach. The bearings are sacrificial, & cheap. I want them to wear out, not the rims.<!-- editby --><em>Edited by Edchris177 on Sep 03, 2022 - 09:19 AM.</em><!-- end editby --> [/quote]
