Update on small scale build

After considering several factors, I decided to start a 3/4 inch tube build size. I had questioned whether or not anything smaller than a 1 inch build would actually work, so decided to test that by going a bit smaller. Also, 3/4 inch pipe allows me to use removable pipe plugs at the outer ends, and this will be handy for experimenting with different water fill depths/weights. I'm going to use schedule 40 PVC pipe for the tubes, and thought about using all clear tubes but that clear stuff is quite expensive, so I decided on just 4 clear pipes. The wheel will be made from a piece of 1/4 inch thick hardboard. I'll be cutting that into two circles for this build. A 3 inch build needs only one wheel, but the end cap for a 3/4 inch pipe is nearly an inch long and would of course interfere with a pipe placed on the opposite side of the wheel. I have laid out the 60 degree radians and bore hole centers on the hardboard, and am now waiting for a 27mm drill to arrive before I can cut the bore holes. This will be very close to the outside diameter of the 3/4 inch schedule 40 pipe that must pass through the bore holes. I'll be mounting the wheels on a 3/8 x 6 inch steel shaft, and of course will need to build a supporting fixture. I'll start posting some photos soon.
