Cheap drag chain idea

Post by tklus » Sat Nov 15, 2014 8:50 pm

Hey Guys,
I am working on building up my first shapeoko 2 and came up with this clever idea for cable management. I am not sure how good it is going to work yet but it looks very promising and extremely cheap. I just stole some of the kids hot wheels track and cut small notches in the sides to allow it to bend.
Think it will work?

You probably haven't seen what cheap Chinese chains go for on eBay... ;-)

Drag chains have a special property; they only bend one way.
(Makes the 'loop' look more tidy, really)

Also, they have the pivot point in the middle of the side, not at the bottom.
Because of that, your chains will 'compress' the cables slightly. Or at least try to do so. That doesn't make for a narrow radius in the bend.
(Commercial chains have a radius of half to about 2/3 of what you seem to achieve)

But if it works... it works... And it's a nice colour :-)

How do you plan to fasten the cables?
(Expect to 'mess about' with the cabling quite a bit early on)

Various sorts of plastic strapping have already been used --- they work quite well, even w/o the one-way bending constraint:

This is a really clever idea! I'm looking forward to hearing how this works out!

So I finally have the machine almost done. The hotwheels drag chain is working great! here are some pics and I plan to get a video up soon.

Thanks,
Tim

Excellent!
Although it does bring back childhood memories of my mom whoopin' my butt with those hot wheels tracks. :(

Heh, this is really cool. But you really do need to epoxy a couple cars onto the tracks like they were zooming around the place.
