[TR] Pain job for 1972 TR6

[Chad]

 I haven't encountered anything like that on a TR6 that I can recall......

  Chad,  
   Diameter of the bolt is the same on the entire shaft instead of tapered like a modern sheet metal screw, and threads were squared off and smooth instead of the angled with a machine bite like a sheet metal screw. 
   

 
 
These are not exactly unique.  In the industry, I think they were branded as Spirox screws, and are generically known as "christmas tree" screws.  They are straight-shank, but have a conical, pointed end, with a modified Acme thread.  They're made to be received by a similar nut encapsulated in a stamped sheet metal clip.  And they're quite adequate for securing sheet metal panels--the panels certainly don't just hang on them.  Otherwise, the car--even when new--would be a rolling symphony of rattles and creaks and knocks.

  
   
   Have you seen an original  TR6 body panel that had primer next to bare metal?  I don't know if it is true what the hardware store WW II employee told me about the Brits dipping every metal part in lacquer paint.  This vet told me during WW II they had these big vats in the barns in rural England and all the metal fabricated parts for everything were dipped and air  dried to prevent rust.  These parts would hang there and be available for the war effort.    
 
 
  He figured maybe after WW II ended, these vats with the lacquer paint and the malleable metal parts that could be re-pressed into what my car was made  from.    
  He's probably pulling your leg (or was an idiot), given that the TR6 began life twenty-four years after the end of the war.  Yes, there were probably leftover parts, but they went with the war materiel in other conflicts (the Brits were fighting what they called the "Malay  Emergency" beginning in 1948 and also had about ten percent of UN's forces in the Korean War beginning in 1950).  Given the extreme shortages of everything in the UK post-war, the chances were very high that unused steel stampings were resmelted.  I think John McC. can attest to the fact that the bodies of everything made at Coventry were made from virgin sheet metal and not made of leftover Doncaster floorboards.
   
 

 
 

 
 
Cheers.
