Door Cards November The 'Crack of Doom' When I bought 'Bee' the drivers door had the 'crack of doom' which is split at the top of the door skin near the front door glass channel. After much study I decided there was a design weakness in the door skin, in that the flange that supports the outer rubber seal ends just before the front door glass channel.
The MGB doesn't have much scuttle-shake - where the screen wobbles from side to side over rough surfaces - but there is some. If this is allowed to waggle the quarterlight frames from side to side, that's when you get splitting of the door skins.
To strengthen the skin I welded a small piece in such that it extended the flange alongside the channel and round the front, meeting up with another flange. The first two pictures from Lyndsay Porters Guide shows the area quite well.
The first shows the area that splits arrowedand the second where I have extended the flange in yellow and blue false colour. Subsequently I saw a Heritage door that seemed to be constructed in just this manner. I MIG-welded the crack, and used a large oval plate behind the door skin to support the door mirror.
It has a slightly larger radius than the door skin, so bracing the mirror over a large area. During a thread on this subject in a mailing list Rich Chrysler posted the text of a BMC Canada Technical Service Bulletin from showing this problem and saying a production change was being made.
My first thought was "well, they never did" but by the date of the bulletin the MGB had only been in production little more than a year and less than 20, had been made, so the problem must have been serious. The drawing in the bulletin shows three edges joining at a single point, whereas the Porter picture shows a slightly different arrangement, and the former would be more prone to cracking in my view.

Following repair it is vital that the way the screen and quarterlight interface with each other is correct to minimise any reoccurrence. The front of the quarterlight frame must only just touch the bulbous part of the pillar seal and not depress it, and 2.
These two adjustments allow the quarterlight frames to be kept static even if when the screen wobbles. The adjustment of the front of the quarterlight frame to the bulbous part of the pillar seal is done by adjusting the fore and aft position of the screen, and its rake.
Other than moving the doors on the hinges which should be done first to get the correct shut-lines there is no other provision for fore and aft adjustment of the quarterlights i.
Note that old seals can be hard and shiny, allowing some 'slip' between frame and rubber. However new rubber is 'sticky' hence the need that the two only just touch, 2. The adjustment of the side of the quarterlight frames to the thin part of the pillar seal to get a small clearance is done partly with screen leg shims to centralise the screen relative to the quarterlights, and by an adjustment on the long leg of the quarterlight frame.M1R21term Paper - Download as Excel Spreadsheet .xls), PDF File .pdf), Text File .txt) or read online.

Background. We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.
Behind each front wheel there is a 'splash' or closing panel which seals the gap between the front outside edge of the footwell and the front wing, having a rubber seal between it and the wing. Sheet metal is metal formed by an industrial process into thin, flat pieces.
Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm ( in) are considered.
The term swage may apply to the process (verb) or a die or tool used in it (noun). Origin. A selection of blacksmithing swages similar to the process of drawing wire.
This may also be referred to as "tube swaging". The second category involves two or more dies used to hammer a round workpiece into a smaller diameter.
