The screw lift does take up a lot of room, but most of that room is used to store balls, so it's not wasted.

Ah, the designs my former team has produced for a screw type lift only accommodate one ball. What are you planning on driving it with?

anyone have any pictures of a ball lift mechanism?

I know that in 2006, my team used a conveyor belt to bring the balls up to a launcher. We used a conveyor belt at the top and guide rails at the bottom. I heard that it worked very well.

The screw is VERY large! and it's not the part that turns.

Our web page has some pictures of the prototype.

Any suggestions on fattening up the center of a PVC pipe to drive a belt?
We intend to use 2 1/2 ID PVC with guides on the way up, aprox 30" long total. The alignment issue is controlled by two eyebolts at the top and a very rigid frame.

Re: Conveyor Belt
 
Maybe you could thin down the edges instead? run the motor that drives the pipe, and hold a file on it. Should only take a day or two to get the profile you want :)

Or if you can find thin sheet PVC material you could glue on strips of it.

There are certain materials that we have discovered to grip orbitballs extremely well..... (a little hint: bedroom would be incomplete without a dresser that can hold clothes in place....) My advice if you cant figure this out, is to bring an orbitball on a date to a hardware store an run it through any materials.

Im looking for some urethane belting material and am trying to find a cost effective way of bonding the stuff. Anyone have any ideas?

Re: Conveyor Belt
 
Does it need to be urethane, or would something like neoprene work? You might experiment with some Pliobond contact cement.

Re: Conveyor Belt
 
It's kinda funny how things work out.

In the last 3 weeks we've tried everything we read on these forums, and it was always one thing or another that went wrong. Finally, last night we came up with our own solution to this that hasn't been suggested on these forums. What we found left some black residue behind, so once we test 2 more materials that are coming in Thursday I'll post what we've done. I knew once I found this stuff when spelunking through TrueValue in Week 2 that we should have used it right away, but alas I'm not the only one on the team.

My tip: stay away from Lowe's and Home Depot when in a search of local hardware stores; they're too big and you'll spend way too much time looking for the right thing. Start with the mom and pop shops that are small and have everything closer together without all of the non-relevant items in between them. On top of that, usually you can touch/sample a material without opening an entire box. Then, once you have an idea of what you want, purchase the sample and test on the prototype.

We are trying to use the surgical tubing is there an easy way to connect the ends so that they don't come apart during competition?

Your answer is most appreciated!!

We have used a conveyor belt material manufactured by Intralox. It comes in multiple widths and uses a variety of sprocket diameters.
