Black Friday Deal got me :)

One other thing about a supported rotary set up is if you have a stock width that will fit the bore of your set up you can reduce you cutting distance compared to cutting from plate. when you look at things like duty cycle that's a big plus when your cutting @ 60% duty. On top you don't have to wear your slats down either, so you reduce your operating cost. so, it makes sense on small parts to keep this in mind.

when you get to a point where you are processing a lot of sheets the skeletons of the sheet add up to quite a bit of wasted material. this is just something you notice if you are around it all the time. i know time is money and that's why it happens but looking for savings can't be forgotten about at the same time.

well i hit my first snag already i picked up 2 air cylinders with the intention of picking a few more up if the plan works out. turns out they no longer have the cylinders i got before in stock now. so i had to come up with a plan B so i found some on AliExpress but have to wait. I guess the silver lining would be i now have a better match for this project now. i should be able to make things smaller as a result.

always something it seems

Something like 3 weekends later and the rotational parts move as they should. I got lucky with my material choices trying to keep things cheap. I ended up with about .005 to spare on the surfaces that mater and ended up with some mismatched surfaces just from the stock not being round. I got lucky this time. now if i can get it to seal in the right places and direct the air in the right places I'm in business the rest is downhill on this on this side. the other end is more complicated yet
 

well, it seals at least. with no pressure it spins pretty nice, but my first pressure test tells me once you add pressure it gets tighter to spin. now i have two air zones by design and i am glad i did not add more to get fancy. once i add a solenoid vale and control the air flow i will only have one zone under pressure at a time and i hope the helps with the spinning. i would be afraid to try and cut the glands any deeper the shaft already pulls itself through the body with gravity when put together. i have to do more testing to see where i am at unfortunately.

This is the one I’m going to follow, I haven’t seen it before, but I started a similar idea in "show your stuff."

i was not happy with the force to spin this thing but it seems the bigger you go the greater the torque needed based on some digging with manufacturer specs i found. i found these that i could buy over seas but they require 3.5 Nm of torque. i'm not sure if that is breakaway or running torque? i'm thinking it's breakaway but i am not sure at this point. if i can figure out a way to test this so i can get a feel for it i might be at a fork in the road moment and end up just biting the bullet and buying these is it seems better than what i was seeing with what i was doing. 3,5 Nm seems like a lot of torque needed?
