That was my thought, too.

Unless he is building a STOL CH701 in there, not much room around his place for a landing strip. http://www.ch701.com/ for those wondering what can take off and land in 200' stretch of grass. (of interest to SFT folks.... check out the homemade tools on that site... lots of creative folks).

Randy have you done any figures on push point solid end of cyl in relationship to the top hinge I have one door i would like to do this way...But it needs to close tight without lifting and it needs to open fully level maybe a bit above level...Jeff

Just joined the site and putting in my 2 bits worth..already

Have you considered a door hinged at the top and folding in the middle with a long hinge(piano hinge idea) To raise it you use an electric winch with 2 cables. The door does not hang out so far and the bottom half rides up and down with wheels on its bottom edge in a track.
These act like a knee and don't go all the way up, or you'd never get them down....

Your life would be a lot easier if you could use a sliding door, even if the track extended beyond the side of the building....

But where's the fun???

Just imagine the weight of a 32x10 foot door sticking straight out from the building. Talk about a sense of pride in knowing you've accomplished that...

Let us not forget that this is not Randy's first rodeo when it comes to bifold doors. If you look back on some of Randy's accomplishments in the past you should feel confident that he will make it happen the right way.

thanks Tommy!
hey you new guys,welcome to the site.

this door is what the customer wants,hes got the money and i have the time!
he wants them to swing up,not bi-fold,not slide or swing.
and after seeing the location of his building i agree.

i've done some country math on the cyl. mounting points and i'll make a test or two before the final mounts are welded to the door.
the hinges are what i need to locate,i want to use a store bought hinge just because its faster than building them.
i've done some looking but didnt see anything i liked yet.
any ideas?

i don't have any idea how to post links but i just built a bi-fold door and the thread is on this site.
building a house/shop in an 8000sf building is the name of the thread,enjoy!

country math = keeping my eyes wide open and looking at how the cyls. are attached on wreckers,farm equipment and everything else,using my redneck laser (builders string) and good old common sense
its not all that hard!!
my helper is off on a drunk or something and my canadian friends are not here yet for the winter,so i'll do most of this alone,thats the worst part!
moving all that steel around with no help.

the doors (2) will power up and down,most likely gravity would bring them down all but the last bit,but if i use both sides of the cylinder the hydraulic tank can be smaller,since one side of the cyl. will be filling while the other is draining,not an even trade,but close enough.

if i only wanted to power the doors up,and gravity down,the way to make them close tight at the bottom would be to angle the door,the door would not be plumb when closed.
i did that to my bi-fold and it closes tight everytime.
the reason the doors don't want to close tight is the location of the hinge pin,being offset to the outside affects the way the door closes.

enjoy the thread!
Randy

Randy, I edited the link into your post. The door discussion begins in earnest at about reply #414 and the pictures of the finished door start with reply #472.
Ah jeez, just read the whole danged thread.

Default If you are looking for info / ideas ~

All of these mfg's offer advice. A guy can order "parts" from Schweiss and Hydroswing for build it your selfs -
http://www.bifold.com/
http://www.hydroswing.com/?gclid=CKC...FQWnlgoduzU0bg
http://www.wilsondoors.com/pages/hydrotec.shtml
As if you haven't checked them out yet - some others on here may find the info handy.
Nice option on a hydro door is plumb in a spot to run it off your tractor or skidsteer hydrolics if power goes down -
Becomeing common now on the farm shops ~
