TC sheet metal gauge

[Mark McCombs]

Group- This is an attempt to see if there may have been a definitive change in the sheet metal thickness in the run of TC's, or if a variation exists. My TC, 8126 EXU, built March 1949, still with its original panels, clearly has sheet metal of 18 gauge, or around .045-.047" thick. This includes the door skins, quarter panels, etc, with the exception of the quarter panel liner sections that fold over the inside of the latch and hinge posts, as these are 20 gauge (.035"). Several people I have spoken with wih earlier TC's advise that their original panels (doorskins, quater panels etc) are 20 gauge (.035"). I have several panels lying around from a 1960 TR-3 and these panels are .045" as well. So, can anyone shed some light on the thought that the later TC's (and perhaps TD's, and other makes) were 18 gauge in the industry after a certain era ?

Just when I thought that every possible angle of TABC research had been covered, - bingo! For what it's worth the sheet metal used on TC 0301, (13th Novemebr, 1945) was/is 37 thou (20 gauge). I think you have opened a floodgate, John TC0301 [Non-text portions of this message have been removed]

Hi Mark, Most of the sheet metal work on TCs that I've come across has been 20 SWG (36 thou. approx. 19AWG). However, 18 SWG (48 thou. approx. 17AWG) might have been used for the panels that needed to be "wheeled" to shape, as the thickness of some areas would have been reduced in the process. Given that both 20 and 18 SWG sheet metal would have been stocked in the panel forming department, and that occasionally they would have run short of supplies, the use of an alternative gauge is quite likely. Supplies of steel products were restricted at that time.

Hello Mark, 1704 is 20 ga. Makes sense with early post-war material shortages. Incidentally, there is a slight difference between SAE and Birmingham Wire Gauge ( Brit equivalent.
