Since I had some shorter pieces of standard PVC pipe lying around, I used it to make cases for some of my Tenkara rods as well. Other than the weight, it worked fine.
Since I had a need to make a number of cases, I had to purchase some more PVC. As I thought about it, Tenkara rods do a pretty good job of protecting their tips when the rods are collapsed. Plus the collapsed rods we short, so they were less likely to get slammed in a car door or meet some other disastrous fate. They were also one piece and had no guides, so I wondered if they may fit into a narrower diameter pipe.
Once at the big box store, I took a look at 1 ¼” PVC. I notice it came not only in the standard wall thickness, but also a thin wall version. I ended up buying the thin wall, and it worked great, still providing protection, but at a reduced weight.
From the picture, you can see the difference in wall thickness between the 1 ½” and 1 ¼” PVC.
Once I built a few cases, I weighed a 1 ½” case and a 1 ¼” case
The 1 ½” case weighed in at 1 lb 5 oz while the 1 ¼’ thin wall case (gray cap) weighed in at 9 oz.
I like this rod case the best, only problem, it requires a level of skill to make -
