But the problem is one of BN270 hangars has a bunch of crunchy stuff that prevents the bolt from going in, and one of the BN220 hangars stops 4mm short (no crunch, it just stops dead like the hole is shallow)

I clean out the bore holes with a Q-Tip and rubbing alcohol. Often there are metal chips in there from the manufacture process. In fact, almost always there have been metal chips in there.

edit: you figured it out

@ZachTetra

Got the BN220 sorted, these little free loaders were hiding at the bottom. M6 for reference

[ZachTetra]

I was using a thin metal pick (looks like a cheap dentist tool) and poking away at it until everything was good

Currently there are some fitting issues with the thread being ever so slightly out of concentric so the bolt ‘sticks’ once per turn

[b264]

If you use Kevin’s axles, I just epoxy them in there and they will never move ever again

Use epoxy as threadlocker. Literally, “locker”

[ZachTetra]

I had to use shoulder bolts, every time I need to do something to the wheels or belts I need to pop them out

@ZachTetra

I must be confused because that’s exactly why I don’t use shoulder bolts.

But if it works for you, awesome

[b264]

If you take a shoulder bolt that is not installed on a truck, and use it to push the wheel onto it, it will take all the spacers and washers and whatnot off the axle and keep them all aligned and together so you can take the entire stack off the axle and slide it all back on. Without fidgeting with all the washers and whatnot

Can also use a long M8 bolt the same way

or even a hex key

Kevin’s axles?? Link please.

@Boardnamics

I’m all out of fixed axles and have the hangers in backorder now. Shoulder bolts are all I have and have emailed everyone who ordered one that I’ll be sending the fixed axles once they arrive for free.

I only preinstalled them upon request because it makes packaging significantly harder with the axles poking out.

I don’t see any photos of them online. Looks like they just went out of stock also.

@Boardnamics update the photos on your site you should show off how awesome those are

And I prefer installing them myself with epoxy in lieu of red Loctite.

[ZachTetra]

What makes epoxy any better? If you want it to really stay I would have thought green Loctite is the way to go

Also I needed the shoulder bolts because I want to run them shorter than the fixed axles and I needed a 10mm shank because 28x10x8 bearings are way easier to get than 28x8x8 bearings

Doing a bit of an overhaul, trying to get my hands on a 42" Demonseed so I can CNC out some bigger wheel wells and a narrower center, and I’ve sold off the old 12s4p and enclosures so I can try again with Nanuk Nano 330 and Small 904 enclosures since they give me more wiggle room (needed the extra room for a beefy charge port and the other electronics for underglow in the battery, and generally more space to fit the ESC)
