[quote=nacraman57][quote]Nice one, I'm not clear how the white washers are staying in place. Is there a large cotter pin through the axle?
I don't know anything about plumbing parts, does a 2 inch Schedule 80 socket flange have a 2.25 inch hole that becomes the wheel bearing in your design?
[/quote] Hope this picture will clarify how the the wheel/flange/axle is put together. The axle is 2.25 OD but the hole in the flange is roughly 2- 3/8" so it allows the flange to rotate freely. The plastic washers are held in place by two stainless screws. You can see the flange holes are larger but the rounded nuts will center flange to wheel.[img]http://www.thebeachcats.com/gallery2/main.php?g2_view=core.DownloadItem&g2_itemId=103187&g2_serialNumber=3[/img][quote]I just cut my 8' beach wheel tube in half, inserted a pipe into each half, then drilled holes for 8', 8.5' and 10' cats. Pete [/quote] Pete, I thought of that too, but taking a hacksaw to a pair of $400.00+ beach wheels would make my feet sweat! This set will stay permanantly with the Wave, so if I'm off somewhere with the 5.7 one of the kids can still use it and have a set of wheels. Besides I was just curious to see if I could do it.[quote]some concernes about the pipe flange not offering a ton of support for holding the wheel strait up and down. How much play is in the system now? Do you have a way to lubricate the flange? [/quote] I think, after using it that there would be more concern with the plastic bolts shearing off than the flange breaking. If that happens I would just rotate the flange a quarter turn, drill new holes and use stainless bolts. There is some play, but not much more "wobble" than the storebought. Getting the plastic washers tight to the flange helps. When there is weight on, the wheels stand straight.[img]http://www.thebeachcats.com/gallery2/main.php?g2_view=core.DownloadItem&g2_itemId=103190&g2_serialNumber=3[/img] I just let water be the lubricant because I felt greasing it would attract sand and wear it faster.[/quote]
