The plates on our 2012 drive gearbox were all press fit together, however we did have 2 bolts running through the gearbox to clamp it shut incase the presses ever came loose.

I've run into a myriad of different issues while attempting to design my own worm drive, so seeing how you guys were able to accomplish it would be amazing!

I’ll be bringing our 2012, 2013 and 2014 gearboxes to SVR

If you need any help with your worm drive gearbox I’m sure Joey Milia would love to help.

That's so awesome! Thank you so much!
Can't wait to stop by 192's pit.

Okay here comes V3, some of the bearing holes became overly sized for some reason and they will be an easy fix but I want to go to bed lol. I also need to add a 3:1 third stage to correct the ratios because as of right now they are way too high. It also now mounts to the KOP frame through 4 tapped holes on the face that line up with the toughbox mounting holes. Let me know what you think.

V3 is looking good!

A few things though:
1. To make facemounting easier, I would go one of a few routes: Put the four bolts holding it together in through the back and tap the front plate (this would give you a flush, flat front) or I would use countersunk bolts on the front instead. The other option is to just have holes for the bolt heads to fit through on the spot you're mounting this. Generally, your mount will be a lot more snug and reliable if the face is right up against the surface you are mounting it to.

2. You probably already know this, but just to remind you, you're going to need another spot for a bearing on the front plate if you intend to add a third stage.

This is a beautiful, elegant gear box. Awesome job on it!

I agree with what you're saying. this is an awesome gearbox, but it would take up a lot of space.

Yeah I did not think about the bolt heads getting the the way I will have to go and fix it but the I add the third stage I will have to face mount to thag any way. The reason I have yet to add the third stage and another bearing because I am not 100% sure how to do it but I will figure it out . As for saving space I am making this box with the intention of making it easy to tuck away and less awkward so I could mount the motors closer together but I choose not too. Thanks for the feedback.

If you need any help with the third stage, just let me know. I'd be more than glad to help.
