I'm gonna classify this as crazy. Making my own antenna mast. Ordered some Red Grandis which is good for outdoors. Making a 5 1/2" x 5 1/2" x72ft tall antenna mast with torsion box construction. And it's going to be on a hinge so I can take it down for maintenance or severe weather. I had a 30ft section built and when I lifted it, it sagged about 1/8". Toughest part of the whole thing was trying to keep it straight as possible with crooked boards.

Lower section, split in two. The base is at the far end and when joined make about 30ft of length.

Trying to keep the top weight down I made a spire

The small part slips in 18" and will be glued and screwed like everything else.
Angle to let water and snow slide off.

Here's all the parts from the bottom side.

And all the parts from the top view.

Each length is about 23 feet with overlaps of about 7 feet.

And here's the hinge, my neighbor is going to weld up the square tube to the 1/4" plate steel and then it gets painted up. It'll sit on a concrete base held down by "J" bolts used in foundations.

Thinking about putting a 2500lb winch on it so it can be raised and lowered easily. Have to figure that one out though.

See.... crazy.

You're way braver'n me, making a wooden "pipe" that tall. Really curious to see how that works out for you, especially over time.

As for the winch, that would be a non-issue if you had an additional primary tower half the height. Mount a pivot on that, attach it to the middle of the long one, and you could rotate it up and down with your little finger.

Gonna be tied in at about 25 feet. Wonder what the weight leverage is gonna be. I doubt it'll be 2500 lbs. Main issue is tying it into the building.

Winch is the current thought. But I have access to Bobcats and large loaders.

All my clocks are digital.

No guying. Ground point and 25' at the top of the building. That's why I made it a torsion box. Self supporting. The weight of the antenna is 3 lbs.

Not to insane when put into perspective. Still dern tall.

Oh... And there's a 10' mast and a 10' antenna on top of that.

Bunch of naysayers. The only thing I have any worries about is the hinges themselves. Other than that I'm not worried about the pole at all.

Leo, piece a cake. There’s a ranch up the road a few miles from mine. I kinda know the guy cause he’s into ol bikes & cars like me. Anyway he owned several pay phones in town. He’s big into ham radio, talks to people worldwide. He put up 2 massive (pyramid) antennas solo and 2 similar to yours

Like I said, not worried about the mast. Pretty sure a glued and screwed torsion box is a sound structure. Gotta do a 16-24" diameter pour 42" down to put the hinge on. The hinge is the part I think is the weak link in the whole plan.

How do I figure out the weight calculation for the winch? I haven't weighed the mast yet but calculated weight is 280lbs. But it's going to be 72' long, tied to the winch at 25'. How much would the winch weight be?

So it's going to be a right triangle with a 25' height and width with a hypotenuse of just over 35'

We are working on this kitchen remodel and the elder lady is very nice, man she watches us like a hawk. She just stands there and watches us and ask us all kinds of silly questions. The good one was this afternoon she noticed the blind corners in her kitchen and asked how she's going to get in there to clean 😳

Did you tell her about the secret hatch?

Mostly sized and epoxied I'll be bringing the slab and the cabinets down to the site for installation tomorrow. Hour drive down there and then an hour back so it's likely to be a long day. I'll be measuring for the upper cabs one of which will be a wine rack that I've already started. The bar is under a set of stairs so the angles need to be accounted for and I have to clip a corner to put an angle onto the wine rack so it should make it interesting.

He brought me the slab and I told him WTF do you want me to do with this? All checked and it was pretty flexible at those cracks. But the epoxy stiffened it up. Stuff is for deep pours up to 4" and takes about 3 days before you can work with it again. Gets stiff enough about 18 hours later so you can move onto other areas on the other side. I taped up the front and poured from the back. Still had leaks that needed to be repoured, fun is.

The challenging part about this one is all these cabinets are hung on single wall redwood. We need a plumber the countertop in and an electrician then we'll be back for the flooring at the bottom of the cabinets toe kick and such. we had to cut out for the breaker box and build a little Chase for the wires coming out of it 😬

Looks nice.
I must misunderstand, seems an odd install protocol.

hmmmm, looking at the panel installation...

Frontal access appears inadequate

Which NEC code do y'all follow ?
