Have you guys experimented with caliper steering yet? I have been trying to figure out how I could mount the bearings to the caliper... Nestor recommended to drill 3 holes in the caliper: 2 for "bearing mount quad block" mounting holes (what a mouthful), and 1 for the axle to go through. Not sure how I would drill through a metal caliper though...
Ideas people? windu I think you worked with calipers for your 2017 electric vehicle, maybe you could clear things up for me?

Re: Battery Buggy B
The two wheel bases are connected with threaded rod. When you turn the threaded rod (make it tighter or looser) it changes the gap on a side. This changes how parallel the two wheel bases are. https://docs.google.com/drawings/d/1XKU ... sp=sharing

Re: Battery Buggy B
I would recommend against threaded rods - they are heavy. It was fine for electric vehicle because we had plenty of motor power, but with battery buggy, you do not. I used 3D printed parts and epoxy to for my caliper steering system. I have pictures on the Best of 2017 page. Additionally, if you want to email me, I can send you additional resources.

Re: Battery Buggy B
Ok thanks now I know how it works!!! So basically your frame is partially threaded rod as well... did you take this approach?cheese wrote:The two wheel bases are connected with threaded rod.

Yeah I thought the same thing. At least 10% of my vehicle's weight comes from the threaded axles alone. If I were to have more threaded rod in my frame... *shudder*... I would have one really heavy vehicle...windu34 wrote:I would recommend against threaded rods - they are heavy.

I will definitely look at the best of 2017 page... and I would appreciate the additional resources
! Should I PM my email to you then?As an unrelated side note, can I upload pictures of my buggy and my tower to the Best of 2018 page even though they weren't the best?

Re: Battery Buggy B
I think as long as you were top 10 at nats, you can post? Idk I don't make those rules haha. Yes please email me, not PM. That goes for anyone who wants resources on steering - I cant add attachments through PM.MadCow2357 wrote:Ok thanks now I know how it works!!!

I did not take this exact approach. I might share in best of 2018 and you will see there.MadCow2357 wrote:Ok thanks now I know how it works!!!
