OK Group,

   

  Yes I have posted a lot because there is no sense in re inventing the wheel, there are so great Kitfox minds to pull from on the list. So what is the VERY best way to make, build, adapt some type of latching unit for the doors? I saw a really cool setup on a helicopter it has pins that came out and was operated from a central turning latch doohickey. 

   I am getting ready to install some bubble doors and was looking for some kind of latching unit that is going to keep the door in place and sealed tight.  

   

  I am thinking of building the door frames either from scratch or by altering  a set that some one might have and wants to part with reasonably. 

   

  I could Tig, Machine, ETC. something together that would not be any problem so there is no limit to your creativity.

   

  Thanks to All 

   Lee

Lee,



Here is how my Series 7 latches are done.  Don't know what model you have but something like this could be fitted to any door with some thought.  These are the optional door latches that Skystar supplied with the kits...I would assume John McBean is still using this same setup and so you could get them from him.

Hi Lee,

         Please put your aircraft type / status in your signature, it 

helps with the answers. (I also like to see full names and locations, too.)

         If you have a IV or earlier, then Lynn just posted a very 

neat installation last week. It uses two pins fore and aft with a 

center crank. I went for a simple latch down low. Murle Williams 

makes one that I couldn't get to work so I fabricated one out of 

aluminum. (Pictures tomorrow.)

What is wrong with the single nylon wing vent type on bottom of door.  Simple, easy and full proof and perfect fit, fast and cheap.  Clint

goes back to building101  = K>I>S>S  and don't add extra weight that is not needed. 



btw had a great day yesterday Ski flying - I would rate it the best of season so far.  Today Fz rain and now rain.   freeze up and snow tomorrow looks like . Winter flying is great, hard to believe that alot just put theirs away when the best performance can be had plus a Zillion places to land.

Clint, that is what I have on my Five.  Very simple,  weigh almost nothing, and best of all, they work.  I think Murle Williams  sells them as a kit.

I've heard of occasions where the door blew open due to flex...Michel  

in Norway comes to mind, but I may be wrong. I may be all wet, but  

wasn't the double-pin door latch utilized on the Speedster for  

exactly that reason? When I ran into turbulence in Tennessee last  

year, that last thing I needed was to have the doors open. If you  

think of the distance between the door hinges and a bottom-of-door  

latch, and think of the flex that might occur in the aluminum-framed  

door (mine, anyway) I feel a lot safer with a mid-door (vertically  

speaking) latch.

Perhaps the later models with their square-tubing doors (they are,  

aren't they?) are built stronger and don't require this almost bullet- 

proof latch. Sometimes in building, extra weight  IS needed.

I don't believe the door blows open.  It is a cam lock like a window vent and when installing the doors, bend frame slightly so the front closes first, then the rear gets pulled in with perfect wind seal.  I cut notches in the nylon to be able to open the door about  3/4 inch on bottom.  This lets in a lot of air on those hot days.  Also, have a small bunge that is used to hold tarps etc connected in the old welding on the door.  This allows me to reach and close  the doors if I decide to fly with them open, taking pictures etc.  Also have a small bolt and washer mounted just under the instrument panel that I connect this little bunge to to prevent the door from flying open when in the cut out notch.  Simple and easy, 10 times as good as my friends double latch, also 10 times as cheap.

 300 hours on this setup, would do it over  again

 Clint 

 P.S. I have flown in a number of planes with front and rear door latches, I just do not like them.

         The bubble doors are incredibly stiff, (and incredibly 

heavy,) and will mitigate this problem.

Affirm, Sir! But only with heavy passenger and under hard landing.
