Another month has passed and I guess it's time for an update.
The back side of the Grove butts up to a state highway and I have a double leaf 16' farm gate on our highway entrance. I knew that eventually the farm gates would need to be replaced with something a little bit more substantial and now the time has come. We've had unwelcome visitors and I'll leave it at that. Time for a new gate.
Back when we did that playground demo job and I saved all of that 5" steel tube, I knew it would come in handy. The new gate will be built from 5" tube.
I wanted that industrial, intimidating looking kind of gate but Laura was not so keen on giving me free range on the design. I sketched 4 pages of designs and Laura poo pooed 2 pages that I thought were pretty intimidating, that left 4 designs and after a brief discussion we agreed on a design.
Time do draw it up in CAD. The gate will be just a tad over 14' so I used concrete for my CAD drawing instead of cardboard. Don't hate on me for having open floor space, that was a requirement when I built this shop. With the full size gate drawn on the shop floor in soapstone, Laura gave the green light and work commenced. Drawing it full size made it easy to measure each element and compare it to the pile of tube I had to ensure I had enough material to build it.
I have a tube coping calculator that lets me input tube size and angle and prints out a template. All the angles in this design are 30*, 60*,and 90* so I made the 90* template first, traced it on the tube and cut the cope with a cut off wheel. It came out nice and needed very little trimming so I made the other 2 paper templates and transferred them to aluminum flashing so that they would be more durable for multi uses.
I got the first 3 pieces of the gate cut and tacked. I'm going to cut and tack the entire gate and then finish weld it. I calculated the weight of the gate a 530*s.
This gate will be automated and will not be hinged to a post, instead it will pivot itself on a single point at ground level. I will have a fairly large concrete base that will incorporate the front wheel spindle/hub from a class 8 truck or heavy fork truck, I'll have to look around and see what I can find. I'm not sure how long this project is going to take because I got bored being retired and took a job driving parts to construction sites.
