Can anyone tell me if they had issues with the doors bulging because of the

seals

kingsley suggested i fit the seals before I set the retaining holes in the

door frame

(thankyou kingsley) which worked nicely, door is flush and even front back

and top, but,

the doors bulge about 5mm in the middle because of the door seals. At this

point the seal

is that tight, i feel you could almost run a pressurised cockpit (keep

dreaming craig)

, how did you all overcome this, Sand the lip the seal is on till it all

fits nicely,

stiffen the door with some carbon maybe, or both, I dont have the "glass" in

the door yet

but i doubt it will stiffen the door enough to hold the 5mm flex that is

present now.

Craig,



Both my doors bulge about 3 mm at the center of the lower edge; this is 

w/o the seals or plexi.

I've yet to do a trial fit with the seals.



Bud Yerly advised use of a heat gun to reduce the bow and eliminate the 

bulge, saying that proper fit before installing glass is essential, 

otherwise getting proper fit WITH the glass is quite difficult.

without the seals the doors are sweet, nice and true, flush all round, its

only now the seal is on, that the door bulges,

its almost like the seal is too hard and is deforming the door.

Craig,

  

 The seals are too thick for the doors, a problem with a number of builders. Even if you didn't have a bulge, it is unlikely that you would be able to close the door from the inside.

 Simple solution is to replace the bottom half appr. of the seal with one of a slghtly smaller diameter.

 The source would be from a company that supplies upholstery bits to people who do restoration of automobiles. If you find one, ask first for a sample.

Thanks for  that karl, 

  

 After talking  to kingsley again, he mentioned the same, given that I was only supplied  enough

 seal for one  door not both, I will have to buy some more regardless. I am thinking I will  also do the shoulder width

 increase at  the same time, and get a seal suitable for that, as you mentioned about closing  the doors, they are hard to get

 closed from  the outside with the seal on. Without a second handle at the back I doubt it  would be possible from the inside.

Craig,



We had a similar experience.  Fitted our doors beautifully and then put on the seal and could hardly close them.  Advice was to get them closed and let the plane sit in the sun so that the fiberglas could attain the proper shape.  It took awhile, but today they fit fine - perhaps a little bulge in the center but they are easy to close and are water tight.  I think I would try this before other suggestions, since if you make the fit looser now, it may end up not being water tight later.  Just a thought.

That´s true.

  

 I changed the seals thinner and made them even thinner from the critical  area (lower section between the shoot bolts). I also gave some heat gun to  refoam the doors. They still keep water and noise well out.

 And closes like BMW´s doors.

  

 It was possible to use original seals but the doors were extremely  difficult to close when seated. Plus I was totally worried about locking  mechanism stresses when closing the handle. And they were bulging ugly.

  

 Third shoot bolt would be ideal against bulging but decided personally it  to be too complicated. Later I understood there would be also an other easier  way to pull the door´s lower middle section inside ja keep it there.

  

 I have also noticed it to be good to keep them normally closed. The seals  get used to be flat.

Thanks jim



Only problem with that idea is it's almost winter, and I would be waiting

about 8 months

for something to happen  and as i mentioned i wasnt supplied enough seal

to do both doors

anyway. I think i will try and get a seal that is a good compromise and then

fill the side

a little so its flush with the door. If i have to change the door seals

again later after

she is flying then its no big deal.

Hi all,



Does any one in the US know the source and part number for a thinner

door seal.  Mine is okay but it is difficult to close the door from

the inside on the pilots side.



Thanks,  Paul

Craig,

  

  You are right. Anyways, if you only change the bottom half, then there is no chance of rain getting in.

 At least, I never noticed it. However, rain does get in via the screw threads of the door hinges, unless you seal them in some way.

  

 Are you sure about the width increase mod ? I considered it and decided against it after measuring a completed width increase. The actual increase was minimal, it is an awful lot of work, and costs more money. I am not exactly a midget, and I have made quite a few long flights without any discomfort whatsoever. 

  

 Keep it simple, man, and get airborne.

  

 Karl

Paul and all,

I have been looking at some in McMaster Carr. Haven't decided on a size yet. Probably a 7/16" diameter bulb. I had a small piece of 3/8" diameter bulb section and it sealed all areas except the rear area adjacent to the lift strut. I don't have the stock numbers at hand at the moment that I was considering but I can post them tomorrow.

I managed to  find a seal suitable at a strut rebuilding place of all the places, the seal  seems ideal, it is a square section

 instead of  round, and is compressed about 50% all the way round, instead of crushed flat  like the supplied one. The offset

 is slightly  less than original so i will have to sand a couple of mm from the lip of the  frame so it looks neat when the door is closed.

 if it is from  UK or US I will get a part number and post it for those  interested

My seals made the  door buldge so I didn't use them and was going to

install some automotive type "half D"  rubber seals.  I had gotten anxious

for the  first flight and had not bothered to install my substitute.  The

cockpit was just fine without any seals at all on my doors,  no drafts 

have been discernable through the  door interfaces in 25 hours  of  flight.

However I made sure of a good fitup of the  doors during the  build.  The 

shoot bolts pull the doors in smartly when actuated.  There  are many

configurations of automotive door and or window seals at body shop or

restoration supply houses. Semi -circle profile rubber  o ring is available

in 1/4, 3/8, or 1/2" dia so you can tailer the tightness or degree of

buldge you are willing to accept.

4 or 5 plies of UNI carbon would have worked too
