Quick additional greenhouse support

It hasn't snowed yet but it's coming. I built a new greenhouse from salvaged carport frames that I picked up. The rafter span was 5 feet just a bit too much for the snowload we get.
To add additional rafters I took 1 1/2 pvc t's made a jig to cut a 45 degree angle. Making sure the cut wasn't too loose an actual force fit for it to snap over the frame pipe. One at the side wall and one at the peak with pipe in between created another support.

That is a nifty solution, thanks for sharing.

Someone asked to see the jig. I used a plug screwed it to the 2x6 making sure the "t" sat flush to the table once seated on the plug. This doesn't show it but 2x4 scraps on either side of the "t" keep it captured and the 45 degree cut on those 2x4's index the cut distance from the fence.

i did pretty much the same thing with bamboo, ready for the snow. last year it made my roof collapse inward

Thank you, Robert - the picture helped a lot.
