I wanted to share the some pics of some pulleys I made last summer. These are 30T and cut out of a gear blank from a gear blank from SPD/SI. At the time, it was my first build and I decided to find a wheel that would be easy to mate to the gear. I chose the Zombie Hawgs which turned out to be made by a local company here in Vancouver BC. I think they are owned by Landyachtz.

To me its a no brainier. Solid Aluminum VS plastic. I will admit that quality is more of a priority in my shop vs cost. We typically want to do things the best way possible. What do you guys think? How has thew 3D printed stuff lasted?
Long story short, that is what I’ve done and here is where I’m headed. I am building REV2 of my board and I have a 38T gear blank here that I want to make gears for Abec11 flywheels 97s or 107s (I cant find 107s). This chunk of aluminum is a monster.
The gear for the flywheels will be so much more complicated in comparison to the Zombie Hawgs but I need the diameter for the hill crushing commuters i’m building.
I am thinking about milling the gears in one or two pieces on the lathe/mill. I should have that done in a couple weeks. The wheels come any day.
