Pics of my Sherman DD after repair of my transmission.
My final gearwheel in nylon of my left transmission has broken due to sand. I think I need to buy new transmission, but I have looked my old metal transmissions and I was surprised, 2 of them are the same than the Matorro sherman transmissions.
I have done the modifications and transmissions works very good.
The video to show the functioning of expanding and closing the sidewall canvas.
The video especially for Pete...

OUT-FREAKIN-STANDING! FRED!

...That's a neat trick you've done.... Heng Long gears in Mato gear cases.... ingenious !

...How long did it take you to figure out the side curtain mechanism? Your servo lever idea is clever indeed... nothing short of a work of art.. everything is very pleasing to the eyes....
So she is once again running? .. are you going to do any more videos of her in the pond ?
AWESOME WORK SIR

Thank you Mike.
It' s not my idea, this idea is from Flametrhower. This member has made a Churchill bridgelayer, a Sherman flail, a Sherman dozer and others crazy projects...

Very impresive Sherman DD build and some very innovative engineering. Well done indeed.

I can see only one problem Fred....that wire extending upwards from the hull in back of the turret... I see you used plastic coated wire... it might obscure your turret rotation... is it necessary? flexible piano wire might be better... but if you don't think it will affect anything then I think what you've done is perfectly fine.... this shot says it all

to me...because that's usually the distance people would view your tank
if they got as close as your close ups... well..if it were my tank..I'd tell whomever to back off lol
Nice job on the final details
Have a Great Day Fred

Hello Mike.
This drawbar is for steering system. It is the tank commander who move this drawbar to left or right for the Sherman turn in water to left or to right.
This drawbar will not be installed during dynamic show, but during static display I will put on.
This drawbar control the rudder...
I hope I was clear.

Fred, when I was working on my M4A2, I found that it has several extra filler caps on the engine deck. There are two on either side of the grills, and sometimes another one centered below the grills. For mine, I used an old Tamiya upper hull, and cut away and sanded down the bottoms of the four that are on it. For a fifth one, you'll either need to rob another hull, or cast one. But, it's an easy way to add them if you have no other source.
I echo Alpha's sentiments - you have made a magnificent build!!
