I don’t see any big orderly shop and expensive tools! Either you work from a clandestine underground location and can’t/won’t take pics, OR you are some kind of master craftsman building all these custom parts with simple hand tools!
I suspect the latter, if that be the case, l’m f*****g impresed!
Yer not an extraterrestrial are you? Those guys built the pyramids a while back.

Where is the gas tank?
Hey Denny,
The battery pack or Accumulator (FSAE term) will be mounted up front (just about over the front axle) :thumbsup:

* Notice the battery "tray" just ahead of the axle?

Spreading the weight around

The ~20 lb. 48V 1,000W electric motor & ~5 lb. 48V 20A controller will be mounted in the rear (just ahead of the wheel)
...then, my azz (~150 lbs.) will reside about in the middle of the chassis (but, most of my weight is biased a bit toward the rear)
...& then, the battery pack will be up front (for some "nose weight") to aid in steering & braking traction ;)

As for a battery pack, first I'm gonna test with (4) 12V 12AH SLA batteries (~35 lbs.)
...then, try (4) 12V 17AH SLA's (~40 lbs.)
...& then, move on to do some testing with a custom 48V 15AH Lithium battery module (~15 lbs.) :2guns:

Well, I'ma glad you asked :thumbsup:

Nope, I don't have a big fancy shop
...just a small garage (mostly full of crap, Um...I mean crafting materials) ;)
...& a workbench (a discarded, old, solid, wooden door) in my back yard
&
Yup, most of my creating is done with just simple (& cheap) HF tools :cheers2:

I yak so much, about my projects
...& post all of these pics, to "Lead by Example" ta "hopefully" try-n-show others what is possible &/or can be done :sifone:

Thanks, for the compliments & noticing :wai:
I always appreciate it when the craftsmanship gets noticed :bannana:

* I do a lot of triangulation
...but, haven't built any pyramids :innocent: (lately) :devil2:

a workbench (a discarded, old, solid, wooden door)
I'd like to elaborate on this "topic" a bit more :thumbsup:

For years I always used a piece of scrap wood, when cutting or drilling, to protect the surface of my workbench from cuts (from cutting)
...& holes (from drilling)
but,
I still worried (or at least was concerned) about cutting or drilling thru
...& damaging the surface of work bench, down below

A few years ago, I came across a discarded solid wooden door
...& I thought that it would make for nice work bench top (Nicer finish & more solid than a piece of 1/2" plywood) :wai:

So, I put it to use as a work bench top :cool:
...but, still used pieces of scrap wood to protect it (& still worried about damaging it)

Beware this next part may be controversial :smiley_omg:


Then, IDK last year or so, I was IDK doing something
...& IDK in a hurry or something (or in a mood who knows)
...& did some cutting or drilling, right directly on the work bench top :eek:
&
Afterwards, it didn't even bother me :innocent::devil2:
...& was actually kinda refreshing, not having to worry about the stupid tabletop
...& just concentrate on the "job" at hand ;)
&
Now, I don't even think about the work bench top, I bolt stuff down, directly to the bench top, to hold it for cutting &/or drilling
...& even have cut a line right on/into the bench top to use as a guide, when cutting several of the same part :cheers2:
Because
A.) I'm already recycling/repurposing & giving the door a second life
...& 2.) it's easily replaceable

Plus, you can get (4) fresh areas to work with, out of the (1) door
because when 1/2 of 1 side of the door gets too "cut up"
...ya just "spin" the door around & use the other 1/2
& then,
When that area gets too damaged, just flip the door over
...& you'll have (2) more "fresh areas" to attack :2guns:

Yo are you saying you are an extra testicle then? I always thought you were a people like most of the rest of us.

While the paint is a dryin' lets discuss GR (gear ratio) & potential top speed :thumbsup:

A MY-1020 48V 1,000W brushed electric motor (~1.2HP) is rated for 3,000RPM's
...& it has a 10T #35 drive sprocket on it

The rear wheel, has a 72T #35 driven sprocket on it
...& has a circumference of ~61"

So, with a 10T drive sprocket with a 72T driven sprocket gives us a 7.2:1 Gear Ratio

Now, let's check the math 🤓

I know there are speed calculators available (online)
...but, I like to use my

Ballpark Equation
MS/GR=ASxTC=IM/FT=FMxHR=FHxMM= MPH

Motor Speed/Gear Ratio=Axle Speed x Tire Circumference = Inches per Minute traveled/Foot(12) = Feet per Minute traveled x Hour(60) = Feet per Hour traveled x MPH Multiplier(.000189) = Miles Per Hour


3,000 (Motor Speed or RPM's) divided by 7.2 (Gear Ratio)= 416.67 (Axle Speed or RPM's)
416.67 (AS) x 61" (Tire Cir.) = 25,416.87 (Inches per minute traveled)
25,416.87 (IM) divided by 12 (Inch per Foot) = 2,118.07 (Feet Traveled per minute)
2,118.07 (FM) x 60 (Minutes per Hour) = 127,084.20 (Feet Traveled per hour)
127,084.20 (FH) x .000189 (mileage multiplier) = 24.02 MPH ;)

IMO getting a top speed of ~24 MPH out of a prototype kart, running on plastic Bicycle wheels & powered by a 1.2HP motor
...seems like a good place to start our testing :bannana:

Um...I can't really talk about it ATM
So tell us about the laser your friends and relatives used to build the pyramids! I never believed the crap about rolling those rocks on logs across the desert. No effen way! Can you imagine that? Its friggen sand after all! The pyramid of geezers! what a great name! I'm betting there is some kind of pocket laser in your garage/shop somewhere. About the size of a zippo, cuts 1" steel like butter! Come awn! time to come clean!

Um...I still can't speak of it :whistle:
...but, "if" I had anything that would/could cut thru 1" steel like butter, I surely wouldn't be doin' it by hand ;)

We got Baby Duckling pics :cornut:
