thin slices of PVC
90mm PVC pipe cut into pieces 40mm long then or rather cut at an angle.... I was tapered pieces 30mm wide at top then 10mm opposite...how would this be done.
I could actually use the 90mm joiners they would still work, slide pipe inside for extra strength and holding then cut that way,
or more intelligent ideas from you please.I would love to grow my own food, but I can not find bacon seeds

It cuts fine on a drop saw if you are careful or a grinder with a 1mm disk if it doesn’t need to be as accurate

90 mm pipe is stormwater pipe and is quite thin and my experience is that cutting very short lengths can crack and shatter using a drop saw.
I use a bandsaw with a 6tpi band to perform these sorts of cuts from longer pieces of stock.
If you want to trim short pieces and wish to keep your hands well away from blades, take a 150 mm length of ducting and cut a narrow strip out of it lengthwise, just enough so that it slides into the short piece. I make the strip slight tapered so that the small piece jams onto the inner piece of pipe.
Then cut slowly and carefully using a BS. Yes you will end up sacrificing the inner piece but this stuff is cheap as chips.
Be careful cutting anything round with a BS as it wants to roll and self feed into the band.
On one occasion the piece grabbed the band and forced the piece to twist and bent the band and it was a mongrel to disentangle it.
I use a mitre slide and slow deliberate movement - no whisking it through the band.

Duct tape!
I'm assuming cutting length wise. Make a jig out of a scrap of ply that matches the angle needed. Put a fence about the diameter of the PVC high along the cut point, The jig should be about 500MM long on each end. Use the duct tape to hold the PVC to the jig at several places along the cut. The deal is that as you run the jig and PVC through the band saw, you'll be able to feel if you deviate from the cut line. As you cut through the duct tape it doesn't matter as you've already cut that area of the PVC.
If I've got it wrong and you are trying to cu the end off at an angle, just make a miter box just wide enough for the PVC. Make the guide cut with a pull saw and use a hack saw to cut the PVC.
