Anyone want to go halves with me on custom door seals for a J model?

Few people know airplane seals as well as GB....

There was a time where MSers were getting money together for basic engineering work to get a drawing of an existing part made...

A go fund me page was started or something of the type...

I remember throwing my lunch money of the day in to help get it started...

I think this was done for the manual gear down lock block...

Just an idea if it is difficult to get other people on board...

Best regards,

Typically... to make a piece of rubber, a long continuous shape... like a door seal...

A tool that is specific to the material and the shape is needed...

It also has to fit the machine that is providing and pressurizing the molten polymer...

Often this piece of metal is called a die... sometimes it is called a tool...

Supplying a piece of the seal... usually informs the die or tool maker all the details they need to know to design the tool...

The machine that the tool gets mounted on is often called a profile extruder...

At the far end of the extruder, is often a water bath, for cooling, and a puller...

Plenty of precision goes into extruding profiles...

 

We could always ask guy if he uses an extruder or how he is going to mold the part...

 

 

PP thoughts only, all stuff I read about somewhere.... probably not MS....  

MS does have a few extruder, injection molder, and tool guys... :)

Best regards,

I'm a bit confused. I sent @GEE-BEE a piece of my door seal a week and a half ago to fabricate the door seal. Why does he need to fabricate more tooling? I thought the tooling is made once and creates the mold of the door seal

It’s funny because I sent him a piece of the door seal five years ago and had 30 people lined up for deposits and that whole thing blew up too.

The gift  keeps on giving, because my door seal was now too short to use for a door seal, I used it  for the baggage door. Then when I ordered a cabin door still two years ago the BA706M seal from Brown changed suppliers ,  and it’s like flat and crushed and that was crap too so now there’s no door seal options

looking at the parts catalog, it seems like the J, K, M, R, S, and I presume the TN all share the same Brown BA-189-139 Seal.

Now if it works! Seals the door properly. I have the K2U door seal and Im not impressed. I know this subject comes up often but nobody ever has the solution for a good, rain out, and quiet door seal.  

Brown aircraft list the T-11001 as a beech mooney door seal.

It sounds like the T11001 is the same thing as a BA706M and without the foam cylinder insert. But again, the rubber that they had it made with is so stiff it’s flat across as a seal down to a half inch of thickness, when you close the door and you can see daylight around it.

I even made a video of it and sent it to Brown and you know what year and a half later still not resolved. But look the old door seal that I bought brand new two years ago is round and cross-section thin and supple. The one on the left is the new version, it’s like pre-crushed flat, even flatter than the 30-year-old seal that’s on the airplane right now, it’s stiff, has no sponginess to it at all

I wonder if anyone has played with trying an open tube with a smaller silicon insert. I did this trick on my F350 and it really improved the quality of the seal.

Gee-Bee wants $295 for the tooling and $125 for a set of silicone door seals.  Anyone care to split the tooling cost with me?  The more the merrier.

At $420 why not just go up to $499 and get the Bob Fields inflatable door seal?

I use boat hatch seals. If they can keep water out from sinking your boat they are good for me. They are much cheaper and available in every boat store. These seals have to withstand a more hostile environment than in a airplane environment.

A inflatable seal on a door without a groove for foot portion of the seal will cause damage to the hinges.

Note:

The seal shown is nothing the same as the oem

The aircraft door seal is rubber foam automotive spec with a peel and stick backing that fails and is too thick and to form duro that causes door to bulge, you get what you pay for.

I will copy in aerospace silicone in 40 Duro and include clear silicone cement.

I will post a pic when complete 

 

The oem 58P baron seal shown, only the center foot inflates and it sits in a channel around the door when not inflated, there is a Rain seal that is on the airframe that channels water away from door when aircraft is static, all pressurized aircraft has them , next time you walk into a Boeing or GulfStream you notice the rain seal 

The front and rear rain seal retail for 5836.00 a pair 

I also stock these and the Boeing helicopter door seals.

Bob Fields Inflatable door seals are amazing. Ask thousands of satisfied customers. Mine was installed in 1987 and still works great.

Boeing helicopter? I know of only a couple of those and wouldn’t think there would be any sales for them?

I mfg md500 Defender and the particle sep seals for various airbus models.

Was this seal made from a J?  Looks just like the one he made for the long bodies in another thread.  Are they the same cross section shape?  I gotta see what my F is supposed to have vs what this one is copied from...
