Doors That Won't Shut Tight

A door that no longer pulls up flush, or needs a firm slam to latch, is one of the most common niggles on a hand-built Aceca, and, reassuringly, usually one of the easiest to put right. Here is why it happens and what the fix involves.

Why coachbuilt doors drift out of adjustment

The Aceca is built the old way: hand-formed aluminium panels over a frame of ash wood and steel tubing, on a tubular chassis. The doors are part of that tradition, aluminium skins over wooden (ash) door frames, and they are substantial, carrying wind-down glass and an opening quarterlight. Two things follow:

  • The wood moves. Ash frames, in the door itself and in the A-post and body they hang from, flex and settle with age, humidity and use. A timber-framed body is never quite as dimensionally fixed as a pressed-steel monocoque.
  • The doors are heavy, and the load goes through the hinges. All that glass and framing hangs off the hinges, which over decades lets the door drop a fraction, enough that it no longer meets the striker cleanly or sits flush in the aperture.

Add a body that can settle slightly on its subframes, and it is easy to see why an Aceca door that shut perfectly a few years ago now needs persuading.

What "won't shut tight" is usually telling you

Close the door slowly and watch what happens, it points to the cause:

  • It reaches the aperture but the latch just misses, or will not pull the door in flush → the striker and latch engagement needs adjusting. This is the common, easy fix.
  • The door has visibly dropped: the gap is tight at the top and wide at the bottom, or it catches the sill or pillar → the hinges, or the wood they are fixed to, need attention before the striker.

A door that only latches with a hearty slam, or springs back off the latch, is the classic symptom.

The fix, usually a straightforward adjustment

On most cars the cure is exactly an adjustment, often made at the door:

  1. Striker and latch: the striker on the body pillar adjusts in and out and up and down, and the latch mechanism sits inside the door behind the trim panel. Moving the striker so the door pulls up flush and latches with light effort, not a slam, cures a great many "won't shut tight" doors. It is a small job in the right hands.
  2. Hinges: if the door has dropped, the hinges come first, re-securing or shimming them, making sure their fixings bite into sound ash (tired screw holes in old wood are a common culprit), and occasionally renewing worn hinges or pins. Only once the door hangs correctly is the striker set.

The honest caveat: adjusting the striker alone to mask a dropped door is a band-aid, it forces the door to work against itself and rarely lasts. A good adjustment sets the door on its hinges first, then finesses the latch.

When it is more than an adjustment

Occasionally a stubborn door points to the ash frame, softened or moved wood in the door or the A-post that no longer holds the hinges or its shape. That is bodywork rather than a five-minute adjustment, and it is worth having assessed if adjustment does not hold. It is also exactly the sort of thing to check when buying, uneven door gaps and doors that will not shut cleanly can flag a tired or moved frame (what to look for when buying an Aceca).

Leave it to someone who knows these cars

Door fit on a coachbuilt aluminium-and-ash car is a feel job, and forcing it can crease an aluminium skin or strip a fixing in old wood. A marque specialist will have an Aceca's doors shutting sweetly quickly, which is the right way to have it done.

Owner's note: a door that has gradually got worse is usually adjustment, not damage. The car settling into its ash frame over the years is a characterful quirk of a hand-built body, not a fault to worry about.
Note. This is general guidance; set-ups vary by car, and door fit on a coachbuilt body is best entrusted to a marque specialist.
