Herm; How much do you have done on your design? I just went thru a design process for building an english wheel, only to find that Kerry's design is what I ended up with, once I applied all the knowledge that I reviewed there on this site.
I have an opportunity to get some 3" x 8" x 3/16" wall tubing locally for cheap and this is what I am contemplating.
I am in the process of building a power hammer (also done in SolidWorks) that I need to finish before starting on an english wheel, and the spring in the picture that you posted sure looks like the Metalcraft / Mittler Brothers spring that I have acquired. Are you working on a power hammer?
The work you posted sure looks nice, keep posting!
