    John why do you have the baseplate? Is it a matter of having something to weld the coupler to?

    Good question Al,

    As you know I have my little quirks.

    I just like to build flexibility into items like this so they are multipurpose for whatever I may need to use them for.

    I decorate for almost all the holidays.

    Sometimes I need to use the "megatree knuckle" to raise and support a prop other then the megatree, in a location different then where the megatree sleeve is buried.

    I have various lengths of 1 1/4 inch pipe depending on the prop and/or application

    Notice the 4 holes on the corners of the baseplate? They allow me to use the knuckle in other locations, by removing the pipe on the bottom of the base, and just use lengths of rebar to secure the knuckle from lateral sideways movement.

    The 2nd pic is the underside of the baseplate. For the megatree, a 1 1/2 inch pipe is screwed into the closet flange and drops into the 2 inch ground sleeve. The length of the 1 1/2 pipe allows the baseplate to set flush with the ground.

    The closet flange is attached to the baseplate using aircraft grade bolts, and can be removed for the other applications.

    Just the way I built it for my uses.

    I'm doing a version inspired by John's design that I've almost got ready. Still doing some tweeking of it but it came out very close to what I had in mind. I've been bouncing questions off John and he has given me the "OMG that would surive a Cat 5 hurricane your a typical engineer overbuilding things" kind of responses so far so I think I'm on track. I'll post some pictures soon, work has been 12 hours a day 5am to 5pm the last couple of weeks and today is my first day off so I'm feeling a little like Walter, but with several more years on the chassis.
    And on the 8th day, God created Christmas lights.

    Glad work is progressing well on it, Dave

    I know in Charlotte you were really going over my base, leaving no part unfondled!

    While you were setting in the floor going over that thing, you looked like a 6 year old (many years ago) with his first Erector set on Christmas Day.

    I still think (from your pictures) that you are trying to build something that would support the Effiel Tower. Way over built!

    But it's yours, and like I did, build it to suit your comfort level. The only bad design is one that falls down, everything else is a good design, no matter what it looks like.

    Look forward to seeing pictures of your final product

    Dave, please do post some photos even partially made will help. I am going to build a knuckle and pour new concrete next week. I dug up my old megatree supports when I cleared and flattened the front yard. I thought I had it figured out until today. I used your drawings to make our shooting (Bang) stars. I'm beginning to like the Bang star name. The name is a double-entendre.

    I bought a 20' piece of 2"x2"x1/2" steel at Dillions the other day. It was about 30% more than a 4' piece at Lowe's. I don't complain too much about the cost of stuff at Lowe's but that kind of got me. And, I don't have an account at Dillions and paid a higher price at Dillion's. I plan to use that steel to make a knuckle maybe 2 for my megatree(s).

    Picked up my pipes today. 1 1/4" by 10' long. I also picked up some 1" x 3' to pound in the ground for mounts, A few guy wires and I'll be good to go.

    Ok here's some photos of my version of John"s Mega tree knuckle. It is built entirely of scrap, so zero $'s. The base plate is 14" X 1/2". The angle iron pieces are 2" X 3/16" X 1'. The square tubing is 2" X 1/8" X 16". The strap on the back is about 2" X 1/4" by whatever fit at that point in time. The hardware is a 5/16" X 1" bolt and a 3" shoulder bolt with locking nut and an assortment of washers to fill the gap and a 5/16" nut.

    I had the 3" shoulder bolts so I made the width of the angle iron and square tubing fit the bolt. The tubing will nicely fit a piece of 1 1/4" black iron pipe and the 5/16" nut welded to the tubing is drilled and tapped through allowing me to thread the bolt through and bind the pipe in place. There are also 4 holes drilled for rebar to be pounded through and the base plate is drilled and tapped for a 6" nipple of 1/2" black iron pipe to thread into from the bottom. I have only a piece of 2" X 2' pipe in the ground for my mega trees so the 1/2" nipple will keep the base from sliding around. I will be using 2 of these this year and adding another heaver duty version for next year. LOL

    I just today got the certificate showing it will withstand a Cat 5 hurricane, I received it from the engineering firm of Bullard, Bullard and Bullard. The second photo shows how I adapted it to be able to be set up as John's 45 degree mega tree he had last year.

    Nice job Dave. I love how that 2" square tubing fits into the channel you made out of angle iron.

    Dave, it really looks great as I mentioned when I sent you the certification of wind rating.

    However, (check the fine print), the Cat 5 hurricane rating is only valid if the hurricane hits your megatree on February 35th, and the tree is being used in the 45 degree mode.

    Otherwise the wind load rating certification certificate for a vertical tree is a stiff breeze defined as 5 -6 mph with peak gust not to exceed 9 mph. ( check the fine print for other limitations and disclaimers)

    Once again, looks good !

    Sincerely,

    Bullard, Bullard and Bullard Engineering

    Vic,

    If that comment was meant to "sully the good name" of my engineering firm, then you will be hearing from my attorneys, the law firm of Stickum, Screwem, and NoLube

    Thanks Dave. It looks great.

    You should get a better engineering firm.

    Watch it, Al or you will also be hearing from my attorneys.

    Just for your information, my engineering firm did not charge Dave. We provided our engineering services in exchange for and payment of "roadie" services from the Carolina Convention.

    Thanks guys, I guess its the die hard DIY (cheap) in me, that and regularly being required at work to make the impossible with no materials. We call it "Making chickensalad out of chickenstuff (cleaned up), you might get it to look the same but it never quite tastes right.
