Phew... I am having a heck of a time posting pictures! Even though they're saved as jpg and reduced in size, I keep getting an error message. Saved them to photobucket. Let's see if this works!
This was my weekend project. The lower bar was added when the single-bar attempt was not structurally sound. Total cost, about $25.
I've been wanting to get my DD a floor bar for some time, but the $100+ price-tag seemed excessive. A wood-working project, however simple, seemed daunting. Working with PVC is just like using big constructo-straws! I did glue the pieces together with PVC glue after I had a working design.
Disclamer: my DD is only about 65 pounds, so I'm not sure what the weight limit would be on something like this. Let's just say that I'm not going to try it.
