I am building a cart from (What Type of Tires and Wheels Do I Need to Make a PVC Beach Cart?). I have a wheel whose central diameter is 3 inches and the PVC for the axle is 1 inch in diameter. I am planning on cutting a wooden circle and attaching it to the wheel and cutting a 1.25 inch hole through the center of the wood so the PVC pipe can pass through the wood. Is this a good idea or are there better alternatives?

Here is a picture of the wheel and tire Wheel and Tire

  • $\begingroup$ are you purchasing trailer wheels for this project? There are better solutions, eg wheeleez.com/polyurethane-wheel-axle-kits of course if you are utilizing some old wheels you have on hand that's a different story. In any case this is really not an engineering topic, more diy.stackexchange material. $\endgroup$ – agentp Jun 27 '17 at 2:42

    $\begingroup$ 3/4 inch pvc (1 inch OD) is awful small for an axle btw. How much weight are you planning? $\endgroup$ – agentp Jun 27 '17 at 2:45

What may be significantly easier is to make an adapter plate that matches the hole pattern on the wheel hub and a pvc pipe flange. The other really easy thing to do at this point is using a frame from a new four wheeled wheelbarrow. The wheelbarrow is belt from those environment, has roughly 1 ton capacity engineered in and it saves you a ton of time which I would assume is worth way more than the wheelbarrow. I hope that this helps.

  • $\begingroup$ I like the flange idea. How should I attach the flange to the axle? Should I just grease both or use bearings inside the flange? $\endgroup$ – Orthopaedic RN Jun 26 '17 at 19:29
