First build! This was after I realized it would be nice to have a way to get to the gym that didn’t involve driving, and sort of escalated from there.
As a first build, it was definitely improvised as things failed along the way. I first started by attempting to build something like the Skatemetric Foosted board, except on a budget. I was able to find cheap 6374’s and went with those on caliber II trucks and ownboard enclosures and battery. I did give it a ride, and had a tough time fitting the enclosures to the curve, and found the standard bushings to be fairly unstable.
I then ordered some riptide bushings, a second battery, and use 3 Seahorse enclosures mounted on the bottom. Wheels are Abec 11 97 mm, with aluminum mounts, pulleys, motors, and belts from Dickyho. The wheel pulleys needed to be drilled out to 1 in (25.4 mm) to clear the trucks, but come with 22 mm bore to add a bearing if necessary.
The vescs are running Ackmaniac firmware, I’ve only ridden it in sensorless BLDC, and there was some cogging at the start, and overall not very smooth. I just set up FOC, and changed the ramp settings to hopefully smooth things out. I also adjusted the throttle curve.
I’m using two mini receivers paired to one remote for now, it’s pretty straightforward and bulletproof.
I have a larger 3d printer on order to make custom enclosures, along with TB trucks so I can mount both motors inboard; having one on the back is just annoying for standing the board up. The deck was cheap, so I don’t feel bad drilling into it. I did attempt to form kydex with a foodsaver, but that didn’t pull vacuum fast enough, and I was itching to get on the board, hence the seahorse enclosures.
A few things I’d do differently:
Order smaller motors, 6374’s are not necessary for a first board, but they were cheap, and I won’t be running them nearly to their limits.
Use black grip tape; it gets dirty fast.
Use one larger enclosure mounted up top instead of 3 on bottom; clearance is fine with the big wheels and riser/6 degree dewedge in the back, but the look of the 3 enclosures isn’t the cleanest. Great for prototyping and setup of electronics though.
For now, I’m still not comfortable on the board, so I’ll probably spend some time practicing on paved trails before taking it on city streets.
And here’s the pictures:
