Well, I have made the Spring in a can! It was about as described, but it took a better welder than I will ever be. I took it to a shop that does anything welding, from big oilfield rigs to old lawn mowers and golf carts. the boss said he wanted to do this job and told me that my design may fail, but his welds won't! He built it exactly as I described and made great improvements. We compressed the spring in the shop by putting the 1 inch tube in a vise, and three big old boys would pull it down while the welder tightened the vise to hold it.

I put end rod bearings (Heim) Bearings on both ends. I like the idea of adjustability. I bought them at a local hot rod shop. The 5/16th bearing on the bottom looks and feels hell bent for strong. The 1/4 inch on the upper end may be OK but I don't know the load rating. So for $20 I am going to get some end rod bearings that have a high load rating. FK or Aurora brand most likely.

Once we were finished, one set would flex just a touch if you pushed the rod back and forth, but the other felt rock solid. I think there was just a bead of slag inside pinning the spring. So today I put a chain on each end and chained them to the tow hitches between my explorer and old suburban. My grandson had it roll forward to flex the setup. It got about 1.5 inch of flex on both of them. Now both feel like they are free. You cannot compress the spring by hand and I was glad to see them move between the two trucks. I was afraid I had made a solid rod!

I wiped it off with denatured alcohol and sanded it. Then I primed it with Rustoleum Self Etching Primer. Tomorrow I will rattlecan paint it with Rustoleum automotive gloss enamel.

I have been teaching ground school at a local flight school (for pay no less!) and work has been getting in the way of getting out to the hangar to work on the Piet.

I have not posted here for a long, long time, but it’s time to do so, just to let people know that I have somewhat reluctantly decided to sell my project. I find that bringing a truly sustainable, regenerative farm into existence is all the ‘project’ I can handle at age 60, so it’s time to adjust.

It’s a very complete project, just about everything you need to complete it is there, although I have to retrieve some engine parts very soon, and then organize everything for anyone who wants a look. About the only thing missing necessary for completion is covering materials. Fuselage is largely complete, tail feathers too. Includes a very nice Corvair engine, already disassembled and partially reworked (crank turned down .001” by Wm. Wynn), much more I could go into but will answer specific questions if you contact me.

Located in NE Ohio, about 40 miles south of Cleveland. Asking $5500 for the whole project, not interested in parting it out.

Thanks!

Kip Gardner, North Canton, OH
