The only thing that I see being an issue is those flat rollers may have difficulty descoring the centre tower. That’s why some have theirs angled inwards, so it can descore after being pushed aside by the PVC piping.
Otherwise, I love it. The indexer set up looks really clean and I love the trapdoor. Best of luck!
You can’t see it very well but it is in fact on a screw join on the linear slide that allows it to swivel inward and outward just enough to descore easily.
All the power to you. If it works, then it works. Personally I like that style better because of its simplicity in build, so if it works then it works.
Just keep in mind, we had too many rubber bands on our rollers last year, and while we could intake 10, both of our arms nearly snapped in half. The metal cracked and even ripped on both sides.
