Seals

Cabin Door Seals

• Many builders decide to put the door seals on the fuselage side instead of onto the inside of the door.
  Two McMaster order numbers are being used: 1120A311 (lip on inside, 3/16 edge thickness, 3/8 high):
  
  
  
  1120A311
  and 1120A313 (lip on outside, 3/16 edge thickness, 3/8 high). Since you are building up the inside edge, the lip is better to be on the inside as the groove for it will automatically form when using a throwaway seal as mold.
  Some builders prefer the 1120A411 variant which is for 1/4 edge thick edges.
  Builders usually sacrifice one set of seals as mold to form out the edges, then replace it with a clean second set. This procedure will need 100 ft total.
  Some builders experience a gap where the ends meet after some time, see this FB thread.

Door Strut Upgrades

• Upgraded strut brackets (especially useful if you use McMaster door seals)
• Heavy Duty Door Strut from Vans (600 instead of 500N)
• Bansbach easylift door strut A1A1F50-100-287 part#10017Y1 (600N instead of 500N, call to order)
• Ordering 650N at Bansbach: Select the 650N version of B0N0F50-100-247/XXXN, add 2 of those, then add 4 of the end fittings A1 M8 Aluminum Hinge Eye Endfitting. These end fittings yield a total length of the 287mm similar to the other fully assembled struts. First timers can try coupon code 15PERCENTOFF.

180 Degree Door Latch and Low Profile Handle Hints

• All-In-One documentation
  Don't miss to check the documentation set at Planearound which includes a link to a document written by David Peterson which is a revised Vans chapter 45 document with all the various modifications compiled in. The chart that goes along with the document is also referenced there.
• Tools needed
  
  • Drill bit to upsize 7/16th door lock pin hole to 11/16th: a 5/8th countersink bit works great, e.g. at HomeDepot
  • 7/16 reamer to upsize the door pin holes in the fuselage, e.g. at Amazon
• Additional documentation
  Damazio's write-up of the 180 degree door latch install. He uses a string to guide the long end rack into the center cam gear box. 20/1000 safety wire works great, too.

  • Ed's low profile door handle install (Note: The 180 degree Delrin handle part has changed, the E-clip now runs against the Delrin, not the strike plate)
  • Austin's door latch and handle install
• Door lock or outer ring (bezel) not sitting flush
  The Aerosport door handle kit assumes a bonded wall thickness of approximately 0.160 inches. It does not include a mechanism to accommodate deviations from this thickness.
  If the door mechanism holes are drilled prior to bonding, and clecos are used during curing, the door halves may compress tightly in the lock area. This can result in a final wall thickness of only about 0.112 inches—leaving a 0.050-inch discrepancy. This difference will cause the outer lock cover to sit proud and not flush with the surface.
  Conversely, if your wall thickness exceeds 0.160 inches, the lock cylinder will sit recessed within the outer cover.
  For doors with thinner walls, a workaround is to trim the collar of the lock so it can sit further down on the steel strike plate (see pictures below). Trimming can be done with a Dremel carbide wheel (e.g. at Home Depot) and a file to make the transition square. It may also be necessary to slightly trim the 3 protruding studs of the outer ring (bezel) back for it to sit flush. For doors with thicker walls, consider designing a 3D-printed collar around the lock cylinder that will raise it to be flush with the cover.

• Low profile door handle hints
  • The outside spring gets between the moving shaft and the low profile door handle. This may cause the inside roll pin not sitting down all the way into the cutout of the steel plate, therefore not properly securing the door handle in the locked position. Consider bending the narrow side of the spring more open so it easily slides over the shaft, and insert the narrow part of the spring first.
  • The roll pin may on first insertion not find the far end exit hole because the initial thickness of the elevated area on the back side of the door handle is preventing the door handle to sit down far enough into the handle enclosure. Very careful sand off the elevated area until the pin inserts properly, and without causing any binding during the handle operation. Grinding the area down too far may foil your attempt to tune the down resting point of the handle so it just doesn't touch the outer skin in the locked position.
