Wing jig details

Without measuring, I bet I got 18" from the rear spar to the ground.

The dog needs to duck when going under them, but doesn't bump them hard at all.

thanks guys! sounds like mounting them at 45" or so will work best for my back and the stands i'm planning to build. i'm not very tall, so that's seems reasonable to me.

i picked up my wing stands today from a local welding shop. they did a good job, but now i have to figure out how to make the holes and angle bracket ledges level.

i am gonna paint 'em before they get installed. any suggestions??

they were a bit more than i would've paid for the wood to do the same thing, but i really like the look of these, and they won't be so overpowering in the shop.

Drill and tap some female threads into the hollow structural steel and bolt the angle stock to it. I think that is what I would do.

Btw, NICE!!!

thanks CJ!

i think that just drilling and bolting would work because they won't be tightened down, if you're thinking that the tube will compress? the angle that the spars will rest on will be adjustable, and be held in place and tightened with the threaded rod from below. does that make sense? rudi has some great pics, and i'll copy his design.

i need to figure how to make all four holes that will attach that piece of angle level to keep the wings level.

That is 2x6x1/4 or 3/16 hollow structural steel by the looks of it. It aint gonna compress!

In fact, it aint goin NOWHERE! Good stuff!

I was thinking about a pivot joint to allow you to level the spars. Through bolt in in the center and a couple of smaller, elongated holes (if required)on either side to secure the angle.

You are STYLIN'!

Hi Chad (CJensen)

Like your stuff...take what is out there ask questions and improve on it...thats what I did with some of CJ's and other's ideas! That is what RVing is about! Making it easier and better for those that come after us.

It is not critical to have the stands, 100% aligned and straight up, you will adjust the arms to be level to compensate for the floor etc. It does not matter if the one stand is slightly scew in relation to the other stand on the other side, since the spar rests on the arms and you will be clamping them down on them. The Arms is the import bit.

Important: Make sure you got a good very tight fit of the stand onto the floor, you don't want any relative movement on the floor.

Drill all the way through the tube and put a bolt through all the way, it compresses very little, but you want the arm adjustable at first, and it is supported by the treaded rod. Then after adjusting you can just make it tight. After tightining it, it is not going anywhere, becuase of the triangular setup.

Here is my post and pictures for reference again.

The bottom arms will be slightly closer to the frame, so I used a wooden spacer block. It is not carrying any load. It is there to ensure you can take out any warp in the wing, and clamp the bottom down.

rudi,

is there any adjustment to the arm where it attaches to the post? like up and down adjustments in an elongated hole, like CJ suggested? seems that if the arm is only allowed to swing on that pivot, the spar could end up not resting flat and end up with some twisting. i plan on punching the holes this afternoon in order to paint it tonight...

also for anyone...how wide is the spar and how far out do your arms reach from the post? i can probably get this from the preview plans, huh...

Sweet!!

spike,

did you get your wings shipped before the price increase?

Post by **Spike** » Fri Jan 06, 2006 12:11 pm

Thanx for reminding me ..... punk! I did not. Though I did call the factory before the increases to find out what they were going to be. It didnt seem like it was financially beneficial to have them shipped before. However, I have made tons of progress this week towards getting back to the project. We had lots of other life things to take care of between the house and such, that the holidays prevented us from completing. The moral of the story is that I hope to be making forward progress real soon

cjensen · Post by **cjensen** » Fri Jan 06, 2006 12:30 pm

sorry dude! but, i'm glad it's not gonna hurt shipping later. hope the life stuff slows down for ya soon, so you can get back to what really matters!

just kidding, of course! as soon as the weather breaks this spring, i know i'm gonna be put to work on re-landscaping the front yard. life...ain't it fun! now go rivet something!

Chad, Rudi's threaded rod arm adjustment setup is really cool and seems precise!

Mebbe something like that would be better than the elongated hole design?!?!

that's what i'm thinking CJ. i drilled the holes and painted 'em today. they will get installed in the shop tomorrow morning...expect some pics!

cjensen · Post by **cjensen** » Sat Jan 07, 2006 9:25 pm

ok, here's the pics from the day's work (it took ALL DAY to do this!!)

i love how that yellow looks with the aluminum!

CJ - What kind of rubber flooring did you use!?! I looked all over today and the only thing I could find that was close were "Cow Mats" at Fleet Farm! They don't lock together like the ones you have.

Let me know what those are and where the heck one could find one!

Thanks! - Peter

Chad, that looks great! The contrast of the yellow and silver DOES look great!

Peter, I got the stuff locally at the odd lot retail store. I have seen Home Depot and Lowes selling similar stuff that comes in 2' squares. I would have preferred that, but I happened upon this stuff first. The supply of these things is very "catch as catch can". It seems that when stores get them, they have them until supplies are depleted and then... who knows when stock will be filled next?

Sears also has carried them. They are not cheap. The few I have cost me $200!

...but they are nice! Watch Home Depot and ask at Sears.

Lemme know what you find out. Others have asked as well.

So Chad with a cool wing jig like that you must be planning on building wings for a living.

cjensen · Post by **cjensen** » Sun Jan 08, 2006 4:49 pm

well...we'll see how this first set goes...

You could probably make some money prosealing tanks for people if someone isn't already doing so.
