2015 - Reverse trike (stingray)

[crazykart]

Finally have an update! Got the rear hubs in finally, somehow the package got shipped to Texas (Poboy, you trying to get my parts? Lol). They sent out all new stuff, and I got it the other day, hubs, keystock, crap ton of locking collars. I'm still waiting on a bunch more to get shipped in, hopefully soon. I'll take pics tomorrow. Got some of the frame parts cut, waiting on a good day to weld it all up, hopefully it'll be fully together next weekend, le sigh.

I have an idea that may allow me to forego buying new rims. Since I have a bunch of atv rims laying around, and the front hubs are atv (wrong pattern for the rims though) I'm thinking about having custom adapters made. Same guy that was going to laser cut the custom hubs for me said he could do it cheap if I design it.

Design is halfway done, simple enough, but I will want feedback (Fabroman, and Machinist@large I'm hoping you 2 could give me a heads up on if you think it'll work or not, I'll upload designs when finished)

Doing the custom adapters would also save me from having to redesign the front spindles, as the ones for the atv hubs are tapered, and if I were to get 4 on 4" go kart hubs then those wouldn't work. Would actually save me a ton of cash as well. $16 a rim + shipping+ whatever for the new front spindles vs $10 an adapter + small to medium flat rate box shipping for all.

I won't even post my idea as to thow the adapters would go yet, as it's extremely hard to follow without visuals and exact measurements. Just know that each adapter would essentially be 2 plates of a36 steel. 1 small plate and one larger. The larger will have 2 bolt patterns in it, and the smaller only 1. Sandwiched together, larger bolted to the hub, and lugs going from larger to smaller to rim...

It's hard to picture, let me get visuals up in the next day or 2. Full deisgns, measurements, and pictures of what I'm working with will help in the opinions on the viability.

Worse comes to worse I'm about 80% sure it'll work in the back without issue. The front is a different story, and if they will work they will have to be exact.

A36 should hold up fine, though I wish it was made of something more near tool steel...

Pics tomorrow, and hopefully finished deisgns!

I really don't know if it will be finished by deadline though. If not I may just shelf it all, and keep gathering parts until next year's build off, idk. I REALLY want to get it done now though. Family life just doesn't seem to be allowing it. Barely have an hour for myself on my days off (my "weekend")

We'll see I guess.

I googled wheel spacer/atv and got a lot of hits, including a lot of manufacturer's. Even if you don't buy from any of them, you'll at least see how the OEM's do it. I'm personally a big fan of one-piece construction because it eliminates a potential fail point.

As someone once observed, if you remove a weak point in the design phase, it'll never be there to fail in the finished product.

 

[crazykart]

I'm a big fan of one piece deisgns as well, but this guy is only laser cutting plates, soooooo ya. Says he can cleanly cut 1/2 plates and anything thicker gets to be sloppy.

I've looked up adapters as well, and the ones that I found, which I've only found ones for the rear, are very expensive.

That's no lasercutting job, that's a CNC milling job from what I understand.

thick plate (say an inch) two bolthole circles
countersunk on opposite sides (the milling job) to flush the bolt heads

So Pat.. any spare time

Not with anything I have at home, and I can't afford to take it to work. The company wouldn't be a problem, it's the fact that the union steward and I have had some serious words in the last couple of weeks.

Apparently us new guy's are supposed to bend over backwards for anyone who has sat on their *** for twenty plus year's. He's filed another complaint against me because I actually do my job.....

(I've only been there for a couple of year's......)

 

[itsid]

Sorry to hear that Pat,
it was meant more as a joke than anything else... still that's not nice to hear

hmmmm....
Gordon, since you're the crazy one...
how about throwing away some safety concerns and actually cast one at home..
play sand, soda cans some styrofoam and a DIY furnace?

Sorry again Pat... couldn't resist this time

[crazykart]

Ive thought about it! Lmao. I already have a bigger mini metal foundry, and a crap ton of aluminum ingots laying around that I cast into small frying pans (dont ask, inside family joke) and no not from soda cans lol.

Sadly I doubt the aluminum would hold up for too long.

Now zamak is another story...

No but seriously, I've seen some of the stuff this guy has accurately cut, which is why I even gave it thought. Thats also whrre the 2 plates come in. Its really hard to explain though ehat I have in my head. Itll make some sense when I get the designs done lol.

Edit: I could cast some, just for mockups, and make sure everything will fit right without any interferrence...hmm

Double edit: I wonder if my benchtop drill press would work well enough to drill the holes through 1" plate....ya right.

Hmmmm decisions decisions.

I had 2 bikes I welded together and put a 6.5 hp engine on it that was registered as a moped.

what? tell me more...

 

[crazykart]

That thing was a monstrosity in the least. It was one full bike, then the back half of another bike, and about 3' of bars in between them spacing them. The side with the half bike got made into something like a side car, meaning I threw on a plastic racing seat lol.

It originally had a 50cc honda spree motor and such on it, but then that crapped out so I threw on a 6.5hp and clutch. Cops never messed with me about it, and I drove it almost everywhere around here lol.

That thing was a deathtrap though.

so you had a title as a 49cc moped, then did an engine swap? that makes more sense. I thought you had bicycles then slapped a HF engine in it (212cc's) and somehow got it in as a 49cc scooter. I'd need a donor bike then, huh?

 

[crazykart]

No it was titled as an assembled moped. There was never any type of inspection or anything, they just asked me a few questions at sos, filled out some paperwork, and got my moped sticker.

I could have had a car engine on it and they would have never known or asked. That was about what 10 years ago I wanna say?

It had all lights, turn signals, and all that fun stuff cobbled on it lol.

 

[Poboy kartman]

Sayyyyyy. man.....Why do they be callin' it a Moped....when you be pedalin' less?????

 

[crazykart]

^^^ thats the reason we need a "facepalm" icon lol

 

[OzFab]

We haven't seen an update for a while; are you still building?

 

[crazykart]

Sadly no. Ran into some problems on the homefront, tree fell through the roof. Been getting that sorted, and it's sapped the cash flow. No way to finish...this year.

Really makes me sad.

I'm going to hold off building til next year's contest, and just collect parts as I can over the winter and spring.

Well under 50% even built so I should be good for reentry.

On an up note I got the roof repaired finally, and my brother gave me 5 golf cart tires and RIMS. One thing I need was those rims because the bolt pattern.

Eh that's life I guess.

Homeowners ins screw ya?

 

[crazykart]

Basically ya. It was listed as a hazard they wouldn't cover because the tree was dead, and it was inevitable to fall.

I was actually planning on cutting it down at the end of the month, but the tree had other plans.

Live and learn I guess.

 

[Lucky7]

That really sucks about your house. Are you going to have to pay for the repairs out of pocket?

 

[crazykart]

Everything was out of pocket, did all the repairs myself. Everything got redone, tore everything off, kinda had to.
