pvc roof rack

Step 8 About 8 hours with one person

Duct tape will help hold the fittings in place until you are ready to glue.
I never glued too early, but if you do, instead of having to drill out the fitting to place a new pipe.
They make a fitting if you cut the one you glued on too early in half. Then cut a little bit more to count for the inside measurement of the 3/4 to 3/4 pipe fitting, then glue when your ready.

This is the first rack I made and did it successfully without gluing too early.
I did not glue until the base was finished and pressed together. If you give gluing some forethought before you glue to be gluing you will be fine. I do not believe you will be able to pull fittings apart after two minutes when you glue. It dries very aggressively.

Lastly, I found ways under the hood to attach the ratchet straps to. In the trunk there were holes in the frame to slip the hook through to ratchet the rack on the back.
Take care in your choice of where to tighten straps of the rack to your car. Your PVC frame can bend by ratcheting it down too tight.
