CAD model of a BD camalot number 1

did a CAD model of the BD number one cam if anyone has use for it you can find it here:

Twist the stem and trigger 90 degrees. Once you twist the trigger, switch which wire goes to which lobe.

And i've got access to CNC.... profit???

Why is the stem trigger twisted off axis?

yea, the trigger is twisted, my bad I will try and change that when I get a chance, it actually will rotate in the model but then the wires will go haywire.

also yes lets make some cams, I have an idea or two about improvements too... this was a start in that direction

Kyle,

I don't know where you got you spec's, measured or received. But I noticed it looks like you've got a few models up you made for, fun? So if you want to take on a small project, I could toss you an idea your way, and you might even be able to generate some money from it having Shapeways produce/ sell it. Would involve modeling the threads on a Kleen Kanteen.

Very much in the realm of no.

One obvious use would be in rendering animated films (CG) with a rock climbing theme. You can get models of common objects - chairs, cars, people - at places like turbosquid, but cams are super specialized and without someone sharing an asset like this you'd likely be stuck modeling it yourself.

Edit: wow, there actually is a cam on turbosquid but it's that other brand...

Its fun. The info is not necessarily useful except as a reverse engineering exercise or someone that wants to make their own cams, which while not an inherently bad idea, just doesn't make sense time/money wise. They are cool little gizmos to learn about though.

Software it was modeled in is solidworks, but you can open it in pretty much any CAD program because I posted the .step and .iges files also the .stl but idk why you would need those. Will try and fix the model this afternoon or next week, and will post an update here when I do so.

specs were hand measured with calipers and are pretty rough, although the lobes were scanned and then traced, they are likely the most accurate.

You could profit from this but you are trying to catch the speeding train that is black diamond. If you are looking for profit it would be smarter to zag in the market place and patent it.

will need to check out turbosquid havent hit that up yet.

Tom Sherman-PM me your idea and/or some contact info no promises but lets talk

like I said in my original post this is a start to understanding current cams in the hopes I could improve on them, mostly in the area of walking, open to others ideas as well.
thank you everyone for the feed back

Just how quickly can you knock out a complete cam?

Hint: It'll be faster to get a minimum wage job and earn enough to buy one from BD. In fact you can earn enough to buy an entire rack before you'll finish the first cam.

Has nobody on MP heard the "1.____, 2.____, 3. Profit!" jokes?

So was just playing around with this in CAD, I didn't download yours, but drew a logarythmic spiral and was screwing around.

Initial thoughts. Does double axle design not actually increas range per say. (Range is inextricably linked to a function of cam angle) But rather double axle increases range relative to overall unit length (width whatever you call it). So that two untis of equal cam angle and equal size, the one with the double axle will have a greater expansion/ contraction whatever???

This is pretty cool stuff! Thanks for the morning buzz.

No love for cam talk here? I only drew one logarithmic spiral and then took the original one and shrunk it by a scale factor relative to Δ distance between two arrangements (axle centerline in single vs. double axle). AKA uniform scale of spiral should be maintaining standards? Correct?

I think you stumped us Tom, I know I cant answer that question without a lot of research.

For the rest of you, I updated the model and fixed the noted error with things being off by 90 degrees, also added some new renders

It looks very nice. Thanks for sharing!

Apparently MP folks don't know about the Underpants Gnomes and their 1. Collect underpants. 2. ? ... 3. Profit! meme. A shocking lack of cultural literacy for a 'net forum... ;-)

Nice job dude. That is some solid work!

I think I learned something.

Cam angle/ logarithmic spirals are a function between planar x/y and so keeping that function a constant, your working in the same game. By using a double-axle or effectively offsetting the axle CL, they are able to package the, call-it, x-gains of a larger value, but packaging it in to a smaller unit by offsetting. pretty simple, but really cool to understand. It's like a headstart. I don't understand the cam angle function enough to draw differences between Metolius and Black Diamond, but would be interesting to see.

OK Kyle, now draw an X4 so I can learn that variable axle bullshit they got goin on there.

It's way better than anything I could do! But... Gotta work on the thumbloop/stem. Something's off there.

But still pretty darn cool!
