What you want is for the frame of the ewheel to (automatically) increase the pressure when you hit a bump. It is not practical to manually change the...
Jerry, you've just described the wheeling machine I built. Instead of a coil spring though I used an air brake chamber from a bus. It has 20 square inches of...
Hi Richard, I think it depends on the size of the bump. For small bumps higher pressure works well, for larger ones graduating from low to high pressure works...
Kerry Pinkerton and I did that kind of testing in 2004, we used a hydraulic cylinder as a load cell and a dial indicator as you describe. Measured stiffness...
I dont want to try and change something that's been working for over a hundred years,or whats not broke don't fix.But the problem I have is I like diversity. I...
Hey thanks. I am just a tinkerer and I like diversity.I want to have bench top e wheel with BIG BERTHA capabilies. I think with a Progressive spring one maybe...
The concept of a spring suspension is interesting, but you'd have to "load it up" every time you released the pressure, opened the gap, and then closed it...
It is much easier,and cheaper,to build a small,stiff,frame. As the throat dimension of the frame increases, the material requirements to maintain the same ...
Richard:We know the frame needs to be able to deflect a certain amount in use.Any idea of a value,when the frame would be considered "too stiff" ? 75 lbs per...
My guess is that anything much over 20 pounds per 0.001 may be too stiff for wheeling welds, etc. I liked the very stiff wheels (20 to 30 pounds) for...

I've just loaded some pictures of my wheeling machine into the photos section. The first picture shows the frame, a c-frame within a c-frame. The second shows...

I can machine up helve hammer dies. I can do 1 1/2, 2, 2 1/2 & 3 inch diameter round radius of 1, 4, 6, 12, 24 inch radius & flat machined in 4140 steel rc32...

Sounds like it would be easy to measure the stiffness of the frame. You've already got a way to generate a known force,just need a dial indicator to measure...
I've thought about that Ian. It would be simple to attach a digital caliper along side the top wheel centerline. These things have a floating zero reset...
The setup that we used, which was a hydraulic cylinder and a gauge, is not capable of measuring the stiffness of the wheel adjuster itself. We used the ewheel...
Sorry it's taken so long to get this ready. I finally borrowed a camera so I could get some pictures online of the lovely flowers you all made. (I'm not a...
