In general, if you are using these 1/4" face gears on the low torque, high rpm portion of your gearbox, it is OK. Gear stress calculations can be done, but if the torque is low, then stress is low. If you put these gears on the lower rpm, higher torque area, I would suggest a wider face width to be safe.

As for a 1" diameter dog shifter with 1/4" prongs sticking out, it is difficult to say. The width and the length of the prong are also important. If your prong's cross section has good area, then you should be ok. From what I recall, the dogs I have been using have about a 0.07 in^2 area, and they work fine. They also only stick out about 0.14".
