Hi, I've been thinking about building a tree. I will want it between 20 and 25 ft tall so its mostly visible above the fence. And I intend to keep the pole up throughout the year, just lowering the lights when the season is over. But unfortunately once or sometimes twice every year , usually in the transition to winter weather, for about 15 or 20 minutes we will get an extremely strong wind. I don't know how strong it is, but it takes shingles off roofs and blasts the paint on one side of my house to bare wood. The rest of the year, very little wind, just nice breezes. My question is what do you think about using a helical pier for the center pole's foundation? I'm not an engineer, but if I understand the selection table at the first link below, a 3.5 inch post can withstand 30,000 lbs of compression and 1200 lbs of lateral force. Does that mean it could hold up to my weather all-year-round? I do have snow and ice in the winter. And I have an industrial metal supply company a few blocks from my house so I can get whatever type of pipe or tubing, square or round, you recommend for my application. I think it might be best to get it all as one piece. I know it would be hard to work with, but hopefully once its up it will stay there regardless of anything mother nature can throw at it. I'm thinking of just drilling 4 holes at the top to attach eye bolts for attaching guy wires. Here's a link to a selection of different helical piers along with their technical specs: www.technometalpost.com/en-US/professionals/selection-table/ And here's a link to another shorter type of helical pier. It looks too small for my main post, but it might be very good for attaching guy wires to. kzbin.info/www/bejne/m6uknWZqobKshZY What hardware would you recommend for my size tree and wind bursts? I'd like a permanent installation for the post and guy wires. Thank you, Sir.
