[quote peter805]Looks GREAT TD. I gone bilt something just like that.
All I need now is the wheels.
Also I see that you dont use glue anymore, just screws.
How is that working out ?

[cool][#0000ff]I DO still use PVC cement, but not on my prototypes and experiments. Once the design is proven I may take it apart and glue the connections as well as using the little 1/2" machine screws. [/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]I started using the machine screws as reinforcements after gluing. Some of my cart designs have experienced joint separations during "extreme" tests. I sometimes take them down long rocky trails to a lake...or down long rough ATV trails along the shorelines. That subjects them to a a lot of torque and twisting. If they can survive the hardest tests I put them through I feel comfortable using them strictly for getting from point A to point B on decent terrain.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Of all the wheels and designs I have tried, the golf cart wheels have worked the best. They are light but strong, and they have a wide "footprint" to reduce sinking in sand and mud. And, by having internal bearings it saves on having to rig an axel for them to roll on. Just twist down the nut onto a rigid bar and you are good to go. [/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Now I have to test the strength and durability of the single vertical shaft to hold the wheels during a punishing test. That may not come for a week or so. So far the results are encouraging. The 1" schedule 40 PVC is tough, but the longer the shaft the more vulnerable it is to torque on rough surfaces. We will see.[/#0000ff]
