Fly press and correct mandrel

_well_ worth a read for the yanks

VASTLY under-rated tool, can do things you can NEVER do with a hydraulic press.

bit like listers, actually about 100 x as clever as it looks

On this side of the pond arbor presses seem to be more common. I'd never heard of a fly press before. What are the pros and cons of each?

You get that big flywheel spinning and when the ram hits, things move, or break.
With an arbor press all you can do is get a longer pipe to put over the handle.  Arbor press is a bit faster for repetitive light duty work like a push broach for a keyway.

nooooooooooooooo

flypress you can adjust, as exactly as you like.

a/ stroke length
b/ stroke speed
c/ stroke force

flypress is absolutely PERFECT for jobs like inserting or removing bushes, bearings, inserts, you name it, also great for punching, bending, forming and all sorts of other kinds of metalwork.

quite apart from the fact NO POWER SOURCE required, you can do everything from punching a 0.5 mm hole in a fresh egg to a 500 ton impact on the same piece of equipment, bed metal into rings of any diameter you like, make folded damask / katana type metals, cut, punch, shape, form, peen, swage, and even WELD with a flypress.

read the link I gave.
