Question about main gears

[kenkamm]

Hi folks,

I don't own a logo (yet) but I had a question about main gears. What main gears are available for the Logo 10 and Logo 14 and what diameter and module are they and how many teeth do they have? I tried looking at Logo parts retailers and information was a bit spotty.

Reason I ask is that I was thinking about toying around with gear ratios for a Trex 600 that are possibly outside the available range of ratios. For instance the Trex 600 has a mod .7, 170 tooth main gear and in some cases one wishes to run a ratio shorter than 17:1 but can't, because a pinion smaller than 10 teeth isn't available (nor practical.) I was wondering if a logo main gear could be modified to work. I saw that a 200 tooth main gear is available, but what module is it? What else is available?

Cheers and thanks,
Ken

200 tooth is module .5 , 138 tooth is mod 0.7. The gears are very different in size and thickness compared to the 600 gear, they are smaller in diamter and thicker. Mikados new Herringbone gears that are coming out are 200+ on mod .5 and the mod .7 is 155 tooth I believe.

Well that's not going to work then, is it! :) Thanks for the info.
