|Thread: Viceroy AEW|
Me mate Trevor has an AEW and has given up on it. Nicely made and so forth but the vertical head sits on the end of the horizontal spindle and as a result there is really no room between the vert spindle nose and the bed: like 4" no room. He's planning to pass his on and bought something much bigger.
They are probably a nice horizontal but no use as a vertical
|Thread: Turning Perspex rod|
Just a few observations to add the excellent info above. I CNC-route sheets of Perspex for a Chandelier-maker. We rapidly discovered the difference between Cast and Extruded grades. I machine using large dia cove cutters at 18000rpm to sculpt the surface of 15mm and 20mm thick sheets. The cast grade is decidedly easier as it doesn't weld to the cutter, but comes off in large curled snowflakes. The sheet, which has had one entire face removed in the process, stays flat, which is not true for the Extruded. I imagine that the extruded has stresses built-in which become unbalanced once cut.
I also machine one side off of 30mm rods from time to time and these machine beautifully using the same settings.
If these experiences have any relevance here then it might be to suggest that very high speeds in the lathe would be worth trying, along with a range of feeds and DoCs.
