Re: 5 speed conversion, rubber cover

[1939mgtb]

What about a fiberglass version? It would be more durable, and could be painted with black bumper paint to give a more "rubber" look. Best, Ray "Much can be achieved with a smile. However, much more can be achieved with a smile and a gun."

I think that is a good idea. Would there be a problem during installation? I seem to remember a bit of contortion when I put my TA together. But I am old and fuzzy now; maybe there wasn't any problem. Cheers Dick Little TA 1326

G'day Mark, With a fabricated metal cover over the gearbox you run the risk of the thing amplifying transmission noise. I had one and the noise was like an empty cement mixer running. I knocked up a cover from fibreglass and the difference is amazing. Simple job too. Took measurements, made a buck out of styrene foam, resin/mesh etc over the top to a build of about 1/4", smoothed the cover with body filler. Inverted, and poured petrol on the foam which then removed itself. Trimmed up and painted semi-gloss black it takes a good hard look to tell the difference from the rubber cover, and it's a lot stronger! Hope this helps Jeff.

The fibreglass trans cover sounds like a great idea Jeff. Did you not use a rubber cover as a form? I have an old one but it is quite limp and would need something to keep it in the correct shape. Anyone do something similar? Allan Chalmers TA, TC

G'day Alan, I did in fact have a rubber cover as reference. This is fitted in my TA. But perhaps I should explain the full picture: Years ago my TC, in the guise of a dedicated racer, had the engine/gearbox repositioned 8" rearward in the chassis. This modification was one of the more radical attempts to improve handling and keep these old things competitive in the early 1960's. Obviously the scuttle also got the chop, losing the front 8 or 9 inches and the battery box... and the toe board became vertical. The rubber cover was now useless, hence the fabricated tin cover. All this work was performed before my ownership. When making the styrene 'buck' for the fibreglass cover it was a simple job to mimic the basic appearance of the rubber cover. Of course it's not a faithful replacement of the original... but then again, neither is the TC in which it is fitted. Hooroo from a cold a wintry east coast Aus.
