One Sunday, some time ago I was laying in the bath and had a brilliant idea (as you do!)
I had been having some trouble the day before cutting some cast steel which had some hard inclusions.
I thought what about using round carbide inserts in a flycutter?! I dismissed the idea as I figured the interrupted cut would chip the inserts pretty quickly. Surfing the net half an hour later and someone had just posted the same idea on another forum! He'd actually clamped his lathe profile tool into his flycutter and given it a try and it worked fine. This is the type of thing he used:

I think I still prefer a very sharp HSS tool to get a real shine on alloy but for most stuff I use the carbide now.
Here's mine.
