Other Computer Aided Handlpole Design

I love the curve!

Taco metals stocks the oval aluminum in 4" width, I saw a few other places where you can get 6" oval via special order

Really, I'm going to have to check that out!

For my future reference I took some measurements.

750sx (stock)
39.5 Length pivot to pivot
7.375 Pole Width (base)
7.5 Base Bracket Opening
6.5" Turnplate Pivot to center of grips
8.375" Steering cable socket to bracket (nozzle straight)
3.75" Steering cable Travel

SN SJ (stock)
39" Length pivot to pivot
7.5" Pole Width (base)
7.625" Base Bracket Opening
5" Turnplate Pivot to center of grips
7.875" Steering cable socket to bracket (nozzle straight)
3.25" Steering Cable Travel

All of the numbers are so damn close the poles could be virtually the same. with minor changes for individual cases. Can anyone confirm these numbers? I would appreciate values for other poles too.

Really the only difference between the two is the steering cable mount. Kawi and yamaha are on opposite sides. We run a Dales pole, like the one on the ski in my picture, on a SN just moved the steering cable mount and run a kawi turn plate upside down. Oh and a couple extra bushings in the pole bracket.

 

[eeerieski]

Technically speaking it makes zero difference to feel.. however to me the under pole turn plate mounting (kawi style) plays games in my head and makes the feeling of the pole very different (for the worse).

Plus having the turn plate above the pole will allow for the pole to be in a lower position when you are holding the bars at the same point compared to the underside mount thus lowering the centre of gravity of the ski.

Riser Bars?

I haven't stopped thinking, If I had an AC TIG welder I would try to tackle one of more of these. I've been doing some searching and those awesome folks over in china would be able to help me with this I bet. I wonder if I could get a pallet of extruded aluminum oval tubing shipped to the states for cheap. Maybe I could fine a manufacturer of extruded aluminum locally? There are at-least 3 places under 100 miles from where I am now, Sadly I would have short runs and changeovers cost a fortune I'm sure.

And some other thoughts I've had concerning the oval tubing, Bending would get more complicated, time spend welding could be cut by 50%, No tight inside welds between tubes, The bottom hinge tube I've been modelling could be tossed with bungs welded directly to the side of the tube for a hinge bolt. The base end could be easily capped in various ways too.

A saying I remember hearing somewhere: why weld when you can bolt, why bolt when you can rivet, why rivet when you can bend, why bend when you can leave the damn thing straight. sadly it doesn't fully apply to this "project". Prototypes would likely be straight though.

And not that anybody is following anymore... I've some up with a name that hasn't been taken as evidenced by a google search and a whois ".com" domain search: Stout Motorsports, not referring to the drink. On second though maybe linking drinking and motorsports in a name isn't the best idea.

Why would linking alcohol to sport be bad ?
Ain't that what the whole redneck racing league is all about ? What would NASCRAP be without its King of Beers ??

Where do you go to school? Im at georgia tech and we learned a good bit about inventor last semester except for the stress analysis part. Ive wanted to find a way to put what i know to use and it seems you have! Looks nice

Penn State, but they teach Pro Engineer, which I think is half as intuitive as inventor yet probably twice as powerful. I've taught myself inventor. The analysis part is dead simple and I recommend you give it a shot for simple structural work. That curve was fun to figure out how to make, At first I was trying to make a 3d solid cut but when that wasn't working out I remember the "extrude to" function and was able to successfully make the 3d surface to extrude to, 6 hours after figuring out the shape that I wanted.

That oval tube is awesome. Thats all I really have to add that's useful.

I might have to give this a try later this week. I have three exams this week but after that i should have some free time. Any idea for other parts that would be good to make in inventor? Poles seem fairly easy for the most part. Just do a sweep of the basic shape along the contour you want and its half done.

edit: this was out class project. It was pretty fun aside from the many many hours we spent in the library doing animations

Any updates on pole?

 

[eeerieski]

Due to my 750sx having a poorly shortened AC pole and my squarenose having a stock pole, I'm fairly certain I will be building at least 2 before summer rolls around. They will be a simplified version of what is shown in post 18. For construction my buddy has a miller synchrowave TIG welder that can do aluminum, Use of it can be secured with a case of beer. To make the radius I'll be using the previously mentioned harbor freight ring roller. I'll need to make turnplates too. No guess on the time-line sadly. I am not concerned about flotation or a spring yet, spring could be added later. I have a few questions:
What is the hinge bolt diameter?
What is the outside diameter of a handlepole bushing (not the flange)?
Where should I get the material? obviously A metal supplier would have it but anywhere cheaper? Machine shops?

 

[Liquid Graffix]

Not sure if this is helpful or not, but here are a few pics of handle pole that I really liked. I plan on making my own for a project this summer so I grabbed these for reference.

Each one has something cool about the design that I liked.

Thanks, you have some pictures there that I don't already have in my inspiration folder. I wish I had a CNC mill.....

How about this for a name..... jetwalker
The .com is available too.

Goose Pole Here. Looks just like the one above. I personally haven't heard of one breaking and I can't find a thread of one that has broke. I do see a lot of parted out skis and one of the first parts to go was the Goose pole. I'll sell this one for $800.

 

[eeerieski]

Another update, nothing to report aside from my lack of employment which is restricting my ability to move forward with this little project. I will not be doing what this guy has done, cheap new billet steering.

I'm looking for a mechanical/industrial/manufacturing/green engineering position or management position in a technical field. I have a BS in Mechanical Engineering from PSU and a Minor in Operations and Supply Chain Managment which is a fancy way of saying lean manufacturing. I'm now living in Columbus, OH with my long time better half who is at OSU to become a Veterinarian.
