We are using the same arrangement exactly... white PVC rings on Black (ABS) Styrene pipe.
We actually ran our shooter using this system at 3500 RPM last night and it worked great... although you have to be careful with alignment at this speed.
If you are collecting you won't need this speed and the ring system should work fine.
We did purchase the mini-welding kit from Fenner... for the tubing...
It is about 1/2 the cost of the fancy one from MC and works great...and I believe it is worth the price...
Here is the link... I ordered directly from Fenner and also got the belting for about 70 cents per foot instead of the 90 cents from MCarr...

This is the link to it... around $250 but worth it if you are using a lot of belting.
Good luck with your design!!
