Hey Denny, The rule book agrees with you :cheers2: ...& prohibits the body of an EA racer to be made from material that shatters &/or produces sharp edges (like plexiglass) ...here is an excerpt from the EA rule book: 5 VEHICLE BODY 1. All vehicles must provide a body/chassis structure...

Hey Denny, I've recently learned that plexiglass is acrylic & shatters ...Lexan is polycarbonate & doesn't Check out this demo video ...Plexiglass (Acrylic) vs. Safety glass vs. Lexan (polycarbonate) * Note the polycarbonate sheet was only 6mm (1/4") ** Now imagine a monocoque built out of...

Time for some CAD (Cardboard Aided Design) :wai: Maybe something like this Front/nose Rollbar To keep the math simple I used a 1/12 scale...1" (in.) = 1' (ft.) So, I started off by cutting a few pieces of (cereal box) cardboard into 4" x 8" rectangles ...to represent a 4" x 8" sheet of...

Did some drawin's while "thinkin' it thru" ...&/with some rough dimensions ...it's a "work in progress" :cheers2:

Hey Denny, I like it :bannana: ...but, thinkin' it thru, that rounded shape introduces some extra challenges :huh: My original plan was to make a couple of box's (top & bottom molds) to lay the fiberglass into ...& then, either bolt or bond (or both) the top 1/2 (of the body) to the bottom 1/2...

Hey T, I've never even thought about workin' with this stuff When researching DIY windshields someone mentioned that polycarbonate was virtually indestructible ...& I was like WAIT...WHAT??? ...& the "gears" (in my little head) started a spinnin' :cornut: Check this out ...then, imagine a...

Hey You'all, Stand back! ...or sit down :sifone: I gots me an idea :devil2::innocent: What if...we design & make a monocoque out of some formed polycarbonate sheet????????? :unsure::popcorn: ...kinda like Transparent Aluminum (IIRC from Startrek 3) Hold on...hold on...hold on, before ya...

Hey T, No worries...mate! :thumbsup: It was hidin' in "plain sight" :huh: Glad you found it :cheers2: Still doin' research :sifone: This is about thermoforming plexiglass windscreens :2guns:

Hey T, Hmmm...it should have been in the box :unsure: ...'cause I knew you would need it :thumbsup: I even cleaned off my work bench today ...& double checked, just to be sure I have another freewheel unit & mount This is what the mount itself looks like (for reference)

Hey T, Left to right 1. wheel flange (not included in the box, because I wasn't sure if we should use 1/8" or 3/16" steel) 2. threaded free wheel mount (included in the box) 3. free wheel unit/sprag (included in the box) 4. 48T (blue) sprocket (included in the box) So, #1 (a steel flange)...

Hey Denny, Yup, To help visualize ...check out this video that shows Polaris with a free-wheeling, rear wheel ...& Sequoia with a direct drive rear wheel * Rear wheels & freewheel unit shown ~4:00 into the video :popcorn:

Been doin' lots of research (reading another book & watchin' some videos) ;) ...& drawin' :2guns: Hey T, I did a drawin' of the free-wheel assembly mounting ...to help explain :thumbsup: The wheel flange (left) ...would be welded to the free-wheel mount (middle left) The free-wheel mount...

That's a lookin' mighty fine! :2guns:

Lookin' good! :thumbsup: I don't remember, did ya post a before pic? (of what your replacing) :popcorn:

Been doin' more thinkin' & drawin' ...& addin' some 3Dness :thumbsup: So, here we have (2) different cars They both have a ~40" "track" & a ~48" wheelbase ...& both are ~34" tall & ~60" long overall & If you look at them from a side view, they look about the same But, "if" we look at them...

I did another simple drawin' ...ta help add a bit more context :thumbsup: * These are just some "off the top of my head" baseline numbers :cornut: Notice, how in this example, the hood & roof line both angle upwards (~5*) slightly, which should: 1.) not add much "induced" drag 2.) not add...

My CVT is acting up, any advice? I'd give it a stern talking to ...explaining what it's doing wrong ...& what it could do, to make the situation...better :cornut: ...& "if" it keeps acting up, maybe try a 30 min "time out" :roflol:

Hey Denny, I'm just about done "jabbering" about the front ...then, we'll move on to the rest of the body :cheers2: I guess, I've been trying to keep these concepts as simple as possible to help folks/students understand how knowledge of how some things "work" can & quite often does, "relate"...

I may be overstating this ...but, I feel like I had an epiphany yesterday :bannana: I realized (Ahhhhhhh:innocent:) that I've been using this empirical concept...like literally...forever ...& IMO it seems to help explain why I've been "butting heads" with so many folks, for so long Over the...

Same topic ...same car ...same info (plus some) ...presented a bit differently :thumbsup:
