DIY Cable Carrier

[epineh]

I still think that the red stripe would be faster

I think if you improve the chain any more you had better put a patent pending on it lol

Looks like I might have to go looking for some small plastic bolts. I know normal steel ones will be easier to find, but might as well keep it plastic.

Good work.

Thanks Russell, and OK, I bow to your greater experience of the optical frequency/velocity ratio controversy.

So you admit that red would be faster then ?

I'm prepared to accept a position of aquiescence, until experimental verification is able to provide unequivocal evidence to the contrary.
I propose to paint the top stripe blue and the lower stripe red and then see which way it curves.

Lol while we are waiting on the verdict on the red/blue quantam physics anomaly, I guess I should get some more duct and see if it will work.

Then I can test the nominal velocity of propagation within the different colour spectrum.

Here's my diy cable carrier. I used 12x20x2mm aluminum U profile and some flexible plastic belt. The aluminum parts are cut to 40mm lenght with 10 degree angle and riveted to the plastic belt. Works like a charm

Hi jetijs,
Nice carrier. How well does it resist drooping when the gantry has extended it fully out ?

Russell - how far does the carrier have to extend when fully out ?

John

Nice work jetijs.

John, well I guess that would be a bit over half the Y axis travel, say about 400mm.

Thanks Russell, but I should also have asked what sort of minimum cross sectional space your going to need for the cable, so I can get a good idea of what the load is going to be pulling the carrier downwards.

Very little, I am only going to have the Z stepper cable, one limit/home switch cable (fig.8 or speaker cable) and the router power cable, lets say the combined thickness will be about the same as your average thumb, a 16 by 25 mm duct would be heaps.

I have some 20mm loom tube that I was going to use initially.

I seem to have hit a wall as far as progress goes on the machine, maybe this weekend will see something happening.

Have a good weekend - I'm trying to shift a propshaft off a transit with twenty years of torque tightening the bolts up !

all of this is great, but i have to interject that a yellow stripe is definately faster than red or blue... hehehe

and i'm beginning to think that some old shopvac hose will be good enough for my machine, yea itll droop a bit, or maby i'll just leave it droopy in the first place... kinda like the hose in a self car wash, it just hangs from the roof, and droops and follows you around...
