Sweet! Certainly a lot lower and I bet a whole lot faster than the original Jupiter.  :D :laugh2:

Came out great, Pablo, and I can imagine that is gonna fly round the Dungeon track!

Thanks, Paul.   :)

 

Billy, I didn't install any upstop mechanisms for the front wheels. Please make sure they don't hang up on the body when placing it on the track.

If it becomes an issue, I'll fix it. Lack of front wheels isn't going to stop this car anyway.  :D

I never built a tripod chassis with independent "L" or "A" arms that needed an upstop on the fronts. The .032" springs should provide all the limitation that you need. Generally speaking, if fronts hang up on a body you can either kick the wheels inward or trim the wheelwells larger.

I am waiting by the mail box, 200 yards from the house. I wish it would stop raining, maybe I should have brought an umbrella  and a sack lunch.

Better bring several sack lunches - it won't be there until Thursday.  :)

Came down with a cold from sitting in the rain by the mailbox, but the car finely came. Looks even better than the pictures, can't wait to run it.

 

Thanks, Pablo,

You are very welcome, sir. Thanks for letting us come race at The Dungeon.
 
Minnie's Go-Kart will be a runner, so stand by... no, not by the mailbox, Billy. :laugh2:

Not without sprinkles, Bill. But blue adds class.  :sarcastic_hand:  Can't wait to see it run tomorrow.  :D

Here's a photo of something I've personally never seen before - a Pro Slot 4002B without a seal :laugh2:
 
IMG_7798.JPG
 
I'm going to blueprint it and install a Havlicek arm just for fun. Yes, I'm aware it may be too much power for a Go-Kart. No shortage of those motors here, so I can always swap it for a stock one.

I just want to see the look on Red's face when Minnie pulls the trigger on it. :crazy:

Before disassembly (in case the alignments were already perfect), I took a photo so I can re-assemble it the same way.

North magnet and positive terminal to the rear, P3 engraving on the end bell up.
 
IMG_7801.JPG
 
Sure enough, the alignments were spot on. Passes the "blank shaft drops though brush holder bar under it's own weight" test.

This time, I got smart (ala dc-65x) and planned where my can brace wire would attach - tinned it before painting the can. :)
 
IMG_7805.JPG
 
Bushings were both tight and well aligned, but the can end needed a slight touch up with the Ungar.
 
IMG_7806.JPG
 
Now, where did I put that doggone pink spray paint? :D

Going to need lots of pink for Minnie.

Sorry to hear you are not making the race. I was sick this month so I didn't get a chance to sweep out the woodshed. If you do make it I'll sweep it real quick. I don't want you getting any splinters. LOL!!!

I know the kart will be great.

This is how I start off jigging up my anglewinder scratchbuilds. Ain't sayin' it's "the right way" - it just works for me.
The body determines everything - wheelbase, guide lead, widths, wheel sizes, style, etc.
 
IMG_7826.JPG
 
.660" OD wheels with .032" clearance needs a spur of .595" OD to be level with the chassis bottom.  A 64p 36t works. So I mocked it up with the wheels, spacers and oilites, then measured the desired tubing width to be .960".
 
IMG_7828.JPG
 
PS 4002B motors are usually geared 7t/28 with .820" OD wheels for a Retro car. Using Pro Slot's "Final Drive Ratio" calculator, this gives a factor of 4.88.

Using my little .660" Go-Kart wheels, 11/36" is a very close match at 4.96.

Microdot of super glue holds the 11t pinion on the jig motor for planning.

Now I can see where I need to trim the tube. I'll cut it too big the first time so nothing keeps the motor from going in nice and tight.

I measured the angle I wanted at 15 degrees, then marked a line on the left/right balance point at that angle.
 
IMG_7852.JPG
 
Then centered the marks on both ends.
 
IMG_7858.JPG
 
IMG_7856.JPG
 
I got lucky this time, it all lines up perfect and the motor is balanced left/right. A couple microdots of super glue hold it on the jig.

Now I can get my good spur gear out of there and make a perfect tube.

Endbell is just a few thou too low to allow a rail under it.
 
IMG_7868.JPG
 
Jig motor endbell comes off, gets shaved down a little, and gets right back in the game. :dance3:

Despite efforts to protect the JK spur, I ruined it anyway. ^_^ So I ground it down a little, re-classified it as a "jig gear" and it went back on. (Good thing I always order at least two of everything.)
 
I found a much better way to secure a jig motor than gluing it to the jig. The chassis is going to need a "can to tube" brace eventually anyway, so might as well do it now. Learned it in a dc-65x "Neat Things" thread. :D
 
IMG_7878.JPG
 
Another dc-65x tip - a slight angle on the edges of the .063" brass center section allows solder to pool where the inner rails connect.
For now, everything is just tacked on in the right places.

Jig motor and jig wheels removed. They are simply an annoyance at this point.  :crazy:
 
IMG_7900.JPG
 
Parts are perfectly centered and flat. Even Go-Karts need precision. :yes3:

It's easier to do it right first time than wonder why it didn't work out later...

Piano wire to .063" brass using the angle trick worked out nice.

Track test #1 on Jupiter: Billy said it smoked his controller. Now I understand why he wanted ME to be the first test pilot. :laugh2:
If need be, we can easily swap motors to something milder.
 
Meanwhile, Minnie's Go-Kart is getting plumbered.

Go-Kart is in the tumbler. :dance3:

I wasn't happy with the can paint results, so I re-masked it and will start over.

This time I'll coat it with white first and we shall see if the pink "pops" any better.

Minnie's Go-Kart chassis is done.

Looks a lot like the Jupiter. But it's an anglewinder.  :)
