Re: 18650 Insulator Rings - Redundant?

Because the edge of the nickel strip can be very sharp and easily pierce through the wrap and existing insulator, that's why you add that extra layer of protection

Re: Finding a machine shop for a simple milling job?

Type machinist into Google maps and start calling?

I think like you said you might struggle to find someone who will do small jobs but you might get lucky

I had someone machine my dropout, brake mount, and torque arm for 50 bucks which was a pretty sick deal now that I think about it

Re: Frame Hole Drilling...

I'd recommend against it. Use stainless cable ties or 3d print brackets, do whatever you can to avoid it

If you do drill make sure you drill the smallest holes possible and deburr them to relieve stress

It's gonna be barely any faster though, the leaf and that 3k mxus will both be able to handle the burst current from that 5p battery you're planning Those cells are rated to 30A. I figured 150A would be enough. What would you recommend ? They're not rated to 30a? And why are you splitting such a sm...
