Just for informational purposes, how would one such as myself go about building say...PVC cages? So far, I know I need to scour the internet for a PVC provider. Beyond that I have no idea how to "weld" it together or anything like that. I'd also like to know what tools are required and all that good stuff.
Thanks!
First, make sure you buy expanded PVC (PVCX) and not regular PVC. Regular PVC is very heavy and tends to flex a bit more due to being a solid material.
If you do go with PVCX, even then you should be careful about the brand. People are often surprised to hear this, but many expanded PVC products are HEAVIER than plywood of the same thickness.
Now let me back up and say that if you go with 1/4" it's really not that big of a deal as even the heaviest PVCX is still pretty light at that thickness.
I have found it's always best to find a local or regional plastic distributor rather than go with US Plastic. I just looked at their site and they have 1/4" black at $89 per sheet before shipping. And the brand they carry is one of the heavier ones, at least it was a year or so ago. Regardless, I'm pretty sure it would cost you over $100 per sheet by the time you had it shipped. I can do better than that by going down to my local sign shop and paying their huge upcharge.
I just ordered TWO sheets of 1/2" in black and got it shipped here and everything for $200. And it's one of sthe lightest brand of PVCX - Celtec 550.
Twice the thickness and the lightest brand of PVCX in the same color for less money.
Welding the stuff together is not too hard. My favorite way is to use at least 10mm thickness and rivet it together. Once assembled I think like to use the water-thin solvent from IPS and inject it along the joints. It wicks in via capillary action.
The big companies thermoform the main carcass of their cages. This saves a ton of time and does make the long edges of the cage easier to clean but it is not the ideal way to make a cage necessarily. A 90" joint made from two panels is more rigid and resistant to sagging than a thermorformed 90* joint.
However, it is a lot more work. The edges of corners of raw PVCX sheet are not very good. It takes some work to prep them for edge glueing. But for a DIY project where labor does not matter I think it's the better way to do it.
I don't mean this as a shot to PVCX cage companies. If I were to build PVCX cages for sale I'd do it the same way.
