I would like to make a roller similar to the ones you see in the image below. I have some back issues and will use it to roll my back open in the morning. The idea is that you drape yourself on your back over the roller and roll your body over it.
I came across one at a friends that I would like to make, it differs from the pics below in that it is stiffer and is meant to support a person when rolling over it and it is also bigger so I was planning to make it out of wood. It is then covered with carpet. I need to take some measurements next time I am at my friends, but figure about 18”-20” high (when lying the long way on the ground) and about 36” wide.
My question is re: the best material to use and the best way to make it.
First, material: I was thinking I could use 3/4” ply and double it up and cut 2 circles for the cylinder ends and then cut strips of doubled up ply to connect between the two circles. I was thinking I could pocket hole the strips to the cylinders—will that method be strong enough if a person is draped over the thing?
I was at home depot today and saw they have pine stair treads that are an inch thick and look pretty sturdy, is that a better way? Or buy pine boards and glue two together for thickness? Still use pocket holes?
In terms of actual construction,the thing has be a round cylinder so I was thinking I would cut a 45 degree bevel into both sides lengthwise of the wood strips to they will mate with the strip next to it on each side and therefore maintain a round shape that will roll.
I think the circle that is formed when the strips connect to the circle ends has to be the same on each side in order for it to be symmetrical and roll and maintain a cylinder shape so I thought I would cut a smaller circle to attach to the two ends and build the circle from the strips around that smaller circle to ensure the two ends are the same? Hopefully that makes sense.
Appreciate any input on the best materials and way to do this to ensure it comes out symmetrical and strong.
