In my garage, I've got this wooden rack - made out of 2x4's. Basically two
goalposts connected and on wheels with a couple extra crossbars. Needs tb a few inches wider to accommodate a new toy. I'm thinking something like 2 or 3-inch PVC pipe would be easier to look at. I *think* I could make it work with regular plumbing fittings and some wire rope/cable tensioners in an X pattern on the sides to stabilize it. Anybody been here? Caveats? Maybe special fittings for rack construction? Pipe size? -- PeteCresswell |

The rack was meant be picked up an moved outside at the beginning of the day. After a couple of weeks ago the joint where two pipes were fitted together broke and the glue failed on another join a week later. The PVC and fittings are just not strong enough to handle moving the rack around. 2x4's are probably cheaper than PVC pipe and fittings too. |

Per John Fereira:
The PVC and fittings are just not strong enough to handle moving the rack around. 2x4's are probably cheaper than PVC pipe and fittings too. Issue: *resolved*.... Thanks. -- PeteCresswell |

The PVC pipe I used (small diameter) deforms quite easily when loaded. All of my support menbers ended up bowed. Blakely |

If the PVC glue connection fails, it is probably because of poor technique
or using the wrong glue for the make of pipe you have. Read the directions on the can and follow them and the joints will be as strong or stronger than the pipe itself. I just took apart a 10 year old rolling clothes hamper made of reinforced 3/4" PVC, and all but one joint (of about 36) could not be broken before failure of the pipe itself. If you are working in cold temperatures or there is moisture condensing on the pipe while gluing, you may have difficulty getting a solid joint, so practice and test some pieces that have hardened overnight. To keep sagging down, inject a little expanding insulating foam into each end of the tube before gluing; use the ridged gap filling type, not the flexible type used for insulating around doors. You can also insert a dowel in long spans to add rigidity. A 3/4" square beam of wood with a little foam on it arranged on the diagonal and running from joint-to-joint can be quite strong for its weight. Use acetone to wipe the pipe down and remove the factory printing. Paint it with lacquer or other solvent based paints or stains to make it look cool. And finally, please, don't risk your life or someone else's by overloading anything on top of a moving vehicle; the roadway is littered with such results. Good luck!
