Re: Original paint spec

Here s what I have learned on paint types used on TCs through my research. I have not tested paint on original pieces to verify, though now I have wings, fuel tank, splash apron, footramp, and toolbox lid with original paint to test the paint for type. I ll do that this week and report. Tub was nitrocellulose lacquer and the rest of the parts were enamel. Bodies Branch painted the tubs (and the bulkhead for the last 5,000 TCs); MG painted the rest of the parts. During TA production, MG installed a new paint system consisting of a conveyor, spray booths, dryer ovens, and exhaust systems. This was disassembled and stored at the St. Helens location when MG converted to munitions work for the war. The fire at the St.Helens location in 1944 destroyed this equipment. After the war, MG wanted to purchase a replacement system, but Nuffield management denied the request (I found written correspondence and meeting minutes on this), noting that enamel paint being used was satisfactory. Other than the health risks of painting with nitrocellulose without proper ventilation - and the added fire risks, I don t know why MG was limited to enamel. People have put a twist on it by saying MG used enamel on wings and parts because it was more durable; I don t think it was the company line. Spec 259, which lists all parts that make a TC (the build book) doesn t help. There is one page listing paint primers, thinners, sandpaper, and cutting compounds. Everything is enamel except for 2 pints of H.S. Black cellulose and 3 pints of Belco Cellulose thinner. Finished doors are listed on the Additional Assembly conditions required for service as finished in cellulose. There is a line in Spec 259 for two pints of APAC Wood Preservative. Anybody know specifically what this was? And now back to your regularly scheduled program. . . . Tom Wilson Holder of lots of trivia, much of it useless

Tom, great research. You can always rely on you for the facts. I had my body painted in modern cellulose  rather than 2 pack. Seems that that wasn't quite correct after all. tel: 0044 741 9905 741 [b]From:[/b] mg-tabc@yahoogroups.com mg-tabc@yahoogroups.com> on behalf of twilson@indy.rr.com [mg-tabc] mg-tabc-noreply@yahoogroups.com> [b]Sent:[/b] Thursday, May 23, 2019 2:22:33 AM [b]To:[/b] mg-tabc@yahoogroups.com [b]Subject:[/b] [mg-tabc] Re: Original paint spec     Here s what I have learned on paint types used on TCs through my research.

Thanks Andrea.
If it wasn't for all the interior and weather equipment orders, the 2 TCs I'm rebuilding, and the 11 MMMs (4 J2s, an L1, 4 PAs, 2 PBs) in line for the next project I'd actually get the book finished!  It keeps sliding, and I know that's not good. Tom

When I did the body tub on my TD back in 1973 Jerry Goguen recommended soaking the timbers I bought from him in a 50/50 mixture of turpentine and linseed oil, like they did when the bodies were being built originally. - Mike Hughes  '37 TA 0512On May 23, 2019 12:49 PM, "Andrea VILLA searunner99@yahoo.com [mg-tabc]" mg-tabc-noreply@yahoogroups.com> wrote:
