Preliminary body

This just shows a preliminary body. Usually what happens if I decide to make a body the night before a race, and it usually turns out half of what I thought it would be.

Getting in and out of the chassis is difficult with the bulkheads in this position. There is a good solution that James came up with where the body is hinged at the front.

This is a good method and I will try to make this work for tomorrow.

Weigh in

Today I'm prepping for an ice event this weekend in Oxford MI. I wanted to spend more time with the chassis tuning and positioning but it's good enough as is. I will need to reposition the pedals at a later date, they are somewhat too close.

The images here show my hanging meat scale and a couple of ratcheting cargo straps. As it turns out my initial weight is 136-140 lbs. I find that the scale is fairly accurate, but I always error on the heavy side by 5 lbs or so when weighing karts with it.

Still this is alot lighter than I hoped for. I think there are areas that I can add lightness to once I start on the aluminum version. But for now this will be a good prototype proof of concept "breadboard" model and will be a good platform for testing many ideas I've had over the years. Stay tuned for ice updates this weekend. -CW

Static Chassis Test

After some detail work getting the brake lines replaced and re-bleeding the brakes (i will report that in a later post) i felt like it was time to do a walk around video of just the chassis. A couple things to note in this video:

a. yes I have wheel chocks - just did a quickie video for the blog
2. the 'go anywhere seat' that is placed here is just for measuring the pedals and wheel position. eventually all that will be updated to something more visually pleasant.
d. because it's cold here (33deg F) and because the oil i'm using is 10/40 and not 5/30 like it should be, the idle is hard to set and the bugger wants to jet off into the sunset with or without me!

Here's the vid...enjoy! (cheesy soundtrack to boot!)



It was pretty funny trying to manipulate all this while one-handing my phone. Also kinda funny watching me attempting to stop the forward movement of the chassis using only the air filter as a hand grip...and even more ridiculous is the foot-on-brake action mid-video. What the heck was I thinking on that? All I can guess is that I was seeing if there was brake pressure? whatever > dumb > hilarious! -CW
