im building a guni. actualy my dad is but i helped design it.
it’ll make more people want to post on this thread.
I’m not one to +1, but here, I’ll make an exception.
Hearing a 13-yr-old proclaim he is about to take on a task that has proven difficult for engineers and machinists with decades of experience, I am left wondering… either I’ve been trolled or I’ve just met a dyslexic genius.
Yeh, it does sound rather ambitious!
Or perhaps he has the parts and is putting them together?! (doubtful…)
Well anyway, it doesn’t look like it’s being followed up very well with
what is a guni??
I’m building a Juni
We are going to start next summer. First I have to decide between pearls and diamonds. Actually my mom’s going to build it, but I am helping with the design.
Geared UNIcycle, like the schlumpf
Give the guy some time. He said his dad was building it and he helped with the design. Building a chain driven geared uni is pretty simple with a giraffe. A good chain design is a bit harder. A planetary design is fairly involved. All of them, however, take quite a bit of time to build parts for and assemble. The guy just posted a few hours ago.
ive already made like five pages of designs and ive figured exatly how it will work. i ran the idea by my dad and showed him everything and he is going to build it not me he works self employed at capo beach equipment rentals and he fixes things and makes thing for a living and he sayed he could do it.
Yeah, with some chain and sprockets, it’s not all that hard, it’s just that people have the lack of equipment to build such a thing, and it has to be heavy… unless it’s entirely titanium/carbon.
way to follow up with designs
I’m just going to assume it is a chain drive giraffe, in which case a full 5 page set of blueprints would be entirely unnessicary…you could even just take a normal giraffe and replace two or three parts…but your choices there…
Post images of the plans or the finished product when you have them available. I’m looking forward to seeing how it looks on paper and in its various stages of construction. I dont know why everyone else has it out for this guy it seems…If he doesn’t build it that really isn’t cheating any of you…its his own loss. I’m assuming it will be an externally geared system as that makes the most sense for a personaly project so I’m curious to see how it will turn out
ive found all the necessary sprockets and some extras. ive also found the tire the cranks the chain and the seat. alot of my parts are salvaged from old bicycles and unicycles should be done in a few weeks to a few months depending on how long the rest takes.
What size wheel are you using?
And why are you making this ? Will it be different from stuff on the market now?
Dude, that is awesome! I need your Dad to build us that 9 foot giraffe we talked about!!!
24 inch wheel and it will probably be a lot like the purple phaze but it will cost a lot less to build then to buy
Ah, so after all the R&D work you’ll have to do to get it working right, you could put a 1:1.5 ratio of cogs on and… well… you’ve got yourself a coker for twice the price and with less of the advantages. Cool!
Good luck with that. You should make it some crazy high great though. That way you can race it and stuff.
Any way that you could post a sketch of the mechanism you plan to use? This would be of great interest to the community and would allow you to benefit from their analyses and critiques.
The jackshaft design that Pete has produced has to be the best that I’ve seen at least for the big 36" wheel. I don’t know how well it would lend itself to smaller wheels and frames due to space constraints. It would be interesting to see if you are able to implement a similar design more simply.
This is what I would do.
Only more compact in the gears chain mechanisms…
I drew it on an angle for sense of great speed because I’m cool.
If I had the machines at home to do it, I would definitely have it built already, though I’m sure I could do it without “proper” machines, and just buy the gears and shafts that I need etc… but it would be very crude looking.
