30 Ft. Flag Pole

admin

My wife has decided that "we" need a new flag pole, a 30 Ft. pole !After pricing poles and recovering from the shock, I decided to build a tilt up pole. I have attached a drawing of what I plan to build and would appreciate your input.One thing I should mention is that we regularly get 70 + mph. wind gusts and she intends for me to fly 2 - flags - 4 Ft. x 6 Ft.Flag Pole.pdfE/S
Reply:1" seems pretty flimsy to me.If it were me I would try to design a telescoping type with 2" being the final size.
Reply:Get a brake off from the power company. They should have some where a car K.O'd them. Just wave down a truck and ask.They're 36 feet so bury it 6' with maybe 10 sacks of sacrete. Get a dude with a backhoe to set it with the back bucket.Last edited by Burpee; 04-08-2014 at 11:35 AM.Bubble gumTooth pixDuct tapeBlack glueGBMF hammerScrew gun --bad battery (see above)

Reply:You bury a bigger tube in concrete.  Then put the pole in the tube, and fill the void with dry sand to get it level.
Reply:2" schedule forty fits a little sloppy in 2 1/2" schedule forty.  I've made flagpoles with that combination that has worked well.  I just  built up the 2" at the end going in and where the end of the 2 1/2" ended.  I've never had an issues on the ones that I've made and installed like that in the twenty plus years that I have done them., not a lot, but when asked if I could.I don't like the pivot concept much.  I have always made a pier hole, at least six foot deep for the footer.  You can place a pulley at the top of the pole and install your cable/rope before you stand it up.Last edited by wroughtn_harv; 04-08-2014 at 11:46 AM.life is good

Reply:[QUOTE=wblewis;4018811]Oooohhhhh, now my head hurts.....Mine too !I talked to the signal engineers at work today and they think my base will be strong enough for 2 - 4 ft. x 6 ft. flags.E/S
Reply:I think your pipes will be too small too. On the ones I've done I used 2 1/2" pipe for the 21' ones and used 2 pieces of 3" channel for the base. I only made 1 taller than that and used 4" channel for the base and I think 3" pipe for the first section. Don't remember much else tho. For the bases I just welded some flats across to hold the channels where they are in the concrete and on the top I welded one flat about 3/8" thick on the back side. Then made a bolt on flat for the front. I drilled a 1/2" hole through the pipe and channels on the bottom for the pivot. Then just tip them up and bolt on the flat and your good. Never had one fail yet.Yeah, I know, but it'll be ok!Lincoln Square wave 255Miller Vintage mig30a spoolgunThermal Dynamics Pacmaster 100xl plasmaSmith mc torchEllis 1600 band saw
Reply:hows it going if your really going to get 70 mph winds  the top 1.5 inch pipe is going to flex to much and will weaken over time from the flexing.  for a 30 ft in 70 mph winds try 4inch or 3.5  pipe 6ft up and 3 inch the rest.  you really want a smooth taper as it wont have any stresser that the step pipes will have. doesnt matter when standing there. but on a windy day how many flex cycles with it have to endure 10x 1000x 1000000xLast edited by Bigrich954rr; 04-10-2014 at 10:23 PM.
Reply:So you think I should 2 1/2 in. with 2 in. pipe inside it for the top 10 ft. ?Will the planned footing be enough for that ?I do get 70 mph. winds 2 or 3 times a year, I have a weather station.E/S
