Mcpit,

Even with your sanding... that drop off is too steep at the connection between pipes. You need thinner tubes. There is no way around this, as playability will be severely hampered from that drop off.

Im not sure if this is the correct diameter.. as Im going by sight / memory. But here you can see the tubes at a local hobby shop, that fit into each other with perfect precision. Tight enough to fit well.. yet loose enough to slide freely. I used the same kind of tubes to rebuild my ICB machine. (had to sell it)

The company seems to have a website, and Ive also seen them selling on Amazon. (not sure if its a reseller, or them directly)

With a small amount of metal polish, these babies will look like a million bucks.

The height difference is like a fingernails difference. You wont even notice it, as the ball rolls over it with quick ease. Anything greater than this... and you will certainly have ball-sticking issues... and control problems.

*edit

Also note.. that ICB's often had failure issues at the connection joints where the pipes are attached. To Eliminate this on my machine.. after I rebuilt mine, I filled the ends of the tubes with hot glue to stiffen the pipes up. I think I also glued and or affixed the tubes with glue to the brackets as well. Filling in any areas, to firm up the whole thing.

It actually works nice! Contrary to the original, I made sure the outside tube was *no shorter* than the full width when in horizontal position. As a result the ball never needs to "climb" the joint. The outside tube always gets "pushed under" the ball when the slope changes from left to right.. if that makes sense..
Result is pretty smooth!

You're right I had great troubles finding the right material and diameters and ended up going with aluminium and slightly larger and thicker unfortunately.
Whereas the ones you found look like spot on! I'll see how far I can go with my current setup. If need be I'll switch to yours, now I have the exact reference numbers! Thanks heaps for that!!

Lucky consequence of my thicker tubes is that they're quite stiff and strong. My problem at the moment is more that the side brackets don't slide smoothly enough (just too much grip + belt too stiff + steppers too weak), I'll post a video. ;)

Thanks!

McPit:
Ball rod control first test.
Stepper motors a little too weak for now, you can hear the left one missing steps. Will need to address that, somehow.

you can share your project?

you can share your project?

Or the image to be able to print and make the holes?

I need if possible playfield design please.

thank you very much!
