Gary is right
I turn a bit of acrylic.....
Best advice is as always.... Sharp tools, allow plenty of time and don't be afraid.
Sharp tools,
yes we have all done it, "I'll do another and then sharpen" NO, sharpen first... Then nice light and easy passes, it will be brittle until you have it round and then it should come off in annoying long ribbons that wrap around everthing.
Time,
Don't try turning in a hurry or rush at it especially not your first time... Again nice light cuts take time, also stopping frequently to remove the ribbons adds to your time.... Finishing WILL take longer until you get the habit of going through your grits right down and then liquid polishes to make it pop
Don't worry,
If you can turn wood, you can turn acrylic, yes it behaves slightly different and each resin will turn slightly different again but YOU CAN DO It!!
Heck I do, my most expensive cast blank was in 3 figures, that took confidence!
One further thing, once turned, always check inside the tube... I use a small round file and a small bottle brush. If the fittings are in anyway to tight wood will give a smidgen Acrylic will not, sometimes tiny bits of casting resin can remain or liquid polish dries in the tube.... 60 seconds with a light pass of a file and then a couple of passes with a bottle brush saves frustration, I have been there more than once...
