Hello all, I've recently been thinking about buying a fly press, but in aus they're pretty expensive usually. Could I feasibly convert an old kick press into a sort of fly press? They are similarly shaped heavy stands but it isn't something I've seen anywhere so I doubt it's a great idea. Any advice would be appreciated 

I’ve sometimes had the same thought, but kick presses simply don’t provide the same amount of force as a fly press. They’re generally designed for tasks like pinching thin sheet metal and setting grommets, which don’t require nearly as much oomph as moving hot metal. 

There’s a good discussion of their pros and cons on THIS THREAD.

Yeah I ended up finding that in my research, would it be possible to turn a kick press into a fly press? Some have very similar style frames and I wonder if the "kick" system could be entirely removed and the body refitted with the threading of a fly press.

I doubt it. First, you have the trouble of sourcing the screw mechanism. Second, the kick press is designed to withstand downward force, while a fly press has to withstand both downward force and some pretty severe torque.
