design phase is over...
I sent out a letter summarizing what I came up with......

Dear Harold, Mike, and Al,
Well, that was fun. Didn’t know I was going to go on a 15-month marathon designing and redesigning the hoist and davit. I was supposed to simply mail the design…
I still need to do that. Hopefully you still open my letters. There is a finished design to be dug out of that stack of letters and notes sitting behind me, I need to do that and assemble it into one complete parts list. I think I’ve explained how those parts are assembled and how the machines work. I added some notes after my last letter, so I’ll include that page with this letter.
So, what is this monster of an idea? Both the hoist and the davit truck are HUGE. Maybe too huge and too heavy to lift to a rooftop? And the davit truck weighs 10 tons… I’m not sure conventional skyscrapers can handle that much additional weight. The vertical truss design that was created for the original twin towers can handle that much weight… but there are not very many skyscrapers in that class. The hoist and davit are still a futuristic design; but that future is happening, there is probably a dozen skyscrapers being built today that utilize the vertical truss design.
I thought it was an interesting design, I thought you 3 would enjoy looking at the concept, and now at the end of all that redesign, the hoist boils down to a battery driven 9/16” wire rope drum hoist. Real fast, real powerful, wireless, onboard power, real safe, with a reach of 2900 feet. It’s a totally DC (direct current) electrical circuit, utilizing a laser/solar panel/Lithium polymer battery and DC power controls to run DC motor generators that drive air cooled, inline planetary gears. The design solves the age-old question of how to spread and guide a wire rope onto a scaffold drum by employing a two-tiered fairlead, precision spreader and a geared wire rope guide that is turned mechanically by the drum. Everything in the hoist design is new, from the open operating area that receives any size pick, to the powerful rollers positioned below the working area, to the fairlead and spreader being located behind the working area, to the stability of the platform, everything is new and improved, to ride in this hoist would feel like nothing ever experienced; powerful, fast, smooth acceleration, and quiet too. You can walk around the stage and it doesn’t move at all, and it is so powerful, it doubles as an outside elevator for material.
Well, another season is upon Harold, and I still haven’t finished mailing the idea. I am just pathetic. I’m going to go quiet for another 4 months, same as last year, but pray for me because I am going to try and finish this project. The design phase is over, so all I have to do is assemble the parts list and finish the drawings… but that still is a lot of work, and the drawings are hard for me, I can’t see what I’m doing, my eyes are too old and the glasses I do own are for seeing far away, I draw with naked eyes… the lines on the paper in front of me are fuzzy, I try to put them in the right place, but it is hard. If I had to build this hoist, it would be easier doing that, because then I could work with an engineer who knows auto-CAD, and I wouldn’t have to draw any more.
My hope is to get something in Harold’s hands that he could show to people after this season is over. I am afraid the drawings will be more along the same line as what I have mailed so far: hand drawn ideas, it is the best I can do.
For the record, I don’t expect this to go any further than mailing the idea to you 3. Any thing is possible if God makes it happens, but I’m not expecting it to happen in my lifetime. If I can package the idea into something cohesive, then someone could end up building it once the world has an actual market for it. Like Harold said, this would be a hoist for China if we tried to market it today… not very practical. When I first thought of the hoist, it needed technology that wasn’t available 30 years ago. Technology has advanced to the point where I can build the hoist today, but it might be another 30 years before there are enough vertical truss skyscrapers built to form an actual market for the hoist. So, it is an idea for posterity. Unless conventional skyscrapers can handle the ten-ton davit truck, which I rather doubt.
