Anyone with experience building a 3 foot machine?

They looked like NEMA 17s but they were about four times bigger!

Thanks, that does actually give me a start!

I literally throw HUNDREDS of steppers every week, often they are $200 each and made in japan, but once a photocopier is end of life, they get trashed and we often just don't have the time to pilfer them, but I am starting to mass a really good collection of extremely high torque 12v and 24v steppers - some of them are $500 ea..
