Kolbers,



When I knew I was going to move from south east Missouri to east central 

Indiana, I started looking for a new EAA Chapter home.  One of the Chapters 

I visited was located at Neil Armstrong Airport (KAXV) Wapakoneta, Ohio.  

The second meeting (and last) I attended was at the home of John Hines, a 

Kolb pilot, because he wanted to show off his new hangar.



I really liked his door, as I thought it was the simplest and lightest that 

I had ever seen. He had purchased the plans and all the hardware and then he 

assembled it on the ground inside the hangar.  From Google I found the 

current supplier of plans.

One of my neighbors has one. Works well using a Harbor Freight 12V worm 
	


drive winch. The hardware kit was very complete, with everything 

included except the wood, door skin structural framing for mounting the 

tracks, pulleys, etc, and the winch.



Potential downsides: door opening must be high enough for the door to 

hang under the opening, since the door partially retracts into the hangar;

for me at least, the installation is pretty complicated, with multiple 

tracks similar to garage door guides and lots of pulleys that that must 

be mounted to structure above & behind the door;

my neighbor built his using regular yellow pine, which is rather prone 

to quick rot when used at grade level (IIRC, he said that the company 

recommends against using treated lumber because of the extra weight);



Potential upsides: it can be opened with a simple hand cranked boat 

winch, and if you install ballast weights on the cable, you can almost 

open & close it without a winch;

you get the shade from roughly half the door remaining outside the hangar.



One thing to remember is that it's only the thickness of a 2x4 on edge. 

If wind is a serious concern, it might have problems in heavy wind.

Charlie E/Gang:



Treated lumber maintains the extra weight until it dries out.  Then it 

weighs the same as untreated lumber.  It also shrinks up quite a bit as it 

dries.

Charlie,



This door needs only about five inches of overhead space in the actual door 

opening.  This is much less than the space required for a bifold door.  

Since this door is lifed and balanced at mid level, there is no bending 

moment applied to the side posts that carry the door weight.  This means one 

does not have to beef up the outside door posts as one would have to for a 

bifold door.



For dry rot, it will last as long as the wood sealer holds up.  One does not 

have to put the bottom of the door on down to ground level.  Only the 

outside sheeting needs to come to ground level.  The bottom door cross 

stringer can be displaced up off the ground by bumpers to prevent it from 

being in constant contact with moisture.



I am not selling this door, but I like the simplicity of the design.  Not 

much to go wrong.  I am restoring an old post and beam barn and will be 

using this design.



I thought the List was getting slow.  No emails.  Sent my self and email, 

and it did not come through.  Called the provider and after they did a 

little tweaking, received 72 emails.



Weird weather.  90 degrees plus one day and the next it in the fourties.  So 

much rain, can't get the mowing done. And so much wind I am afraid to open 

the sliding hangar doors.
