Just thought I’d share something.
For my first build (which I started about 2 years back on endless-sphere and still haven’t documented here), I designed my own everything. Deck, motor mounts, battery pack and charging mechanism, enclosure, etc.
The motor mounts were particularly interesting. In those days, Enertion, Alien Drive Systems and DIYelectricskateboards were selling these crazy expensive machined motor mounts. I couldn’t afford that at the time, as well as batteries and motors, so I decided to try something different. This was before @psychotiller’s mounts, which I believe are the best bang for buck out there at the moment, barring my own.
Here cometh the laser cut alu plate. I worked out a way of stacking laser cut alu plates of different thicknesses to create my driven pulley and wheel mount, as well as the motor mounting brackets. A little bit of thinking and some cad work got me a pair of light, high performance (possibly higher than what was out there then) wheel pulleys and motor mounts. I remember my order from the laser cutters back then was less than $100 for 2 drive sets, 2 motor mounts and a lasercut and bent alu battery and electronics enclosure.
For all of those out there trying to do this on a budget, with more time than money: get yourselves a CAD package - the open source ones will do, and design your own parts. Send the DXFs off to the laser cutter and there you go. Laser cut (and bent) plate is the cheapest easiest way to manufacture custom parts anywhere in the world at the moment.
Anyone else done their own design and manufacturing of the critical mechanical eboard parts (wheel pulleys and motor mounts) to save costs here?
I’ll post some pictures and screenshots of my previous design, as well as the one I’m currently working on for r2 when I get a chance.
