The large backgear is a press fit, at least it is on my spare. You may have a mix. 14.5° gears have a rounded root whereas 20° is flatter, or is it the other way around? Whichever, you can see the difference between the two from both the root profile and tooth profile. |

Hi Seadog - Yes, it's a press fit on mine too, with a thin (1/8" maybe) round pin serving as a key to prevent it rotating on the shaft. I know it's a very light press fit as I can move it a little if I push hard on the shaft with my thumbs whilst holding the large gear... Turns out, it's not as easy to get hold of plasticine in the shops as I expected it to be.... so I've had to order some instead. Along with a protractor (10 off!!!) and an angle ruler which I may or may not find a use for one day. So tonight I'll have to make do with using the Mk1 eyeball, or maybe I'll just rest up tonight. I may need to plan some more purchases for the weekend... |

I buy mine from a supplier of casting materials, resins, fibre glass matt etc. Artists suppliers should stock it! Regards, Matthew |
