It's coming when I eventually convert to PC/LinuxCNC controls. A feed
screw for an expeller oil press is on the A axis project agenda.


Pete, I know it's fun to just "make stuff". But I suspect that by the
time you buy the stock and spend a cutter and hours of machining time...
that you'd have been able to buy an Acme screw for less.

I have built several 'dough extruders' for pyrotechnic manufacturing.
There's just no recognizable benefit (if costs count) for making a lead
screw. Too many manufacturers make them for _really_cheap_.

It's not an Acme screw or other lead screw, it's an auger kind of feed
screw. Take a look at http://www.piteba.com for a small example.

That expeller looks very flimsy to me.

It certainly isn't up to my over-engineering standards, but as it turns
out it is very reliable and more importantly simple to maintain for the
3rd world market it's largely for. Search for it on youtube and find it
in use in all kinds of interesting places. For my use I want to make a
slightly larger powered version.
