I want to machine some aluminum bronze for some bushings but have never
tried to turn it on a lathe. Is it tough and tricks or tips ?

I've never had any solid Al-bronze to work with but I have built up some
shafts with AMPCO 200 and turned that down to size. I used TNMP-321
uncoated carbide inserts and it went well. These were in my tool
holders

which give 5degrees positive rake. I say uncoated because they are
sharper than coated.
