How about the treadle and so on from an old sewing machine?

My Mum's old Singer is still going strong and it has heaps of control when
used from slow speeds to flat out!

11 lathes, 3 milling machines, 3 surface grinders, 6 drill presses, means
you will only need 23 sewing machines and a few extra for the odd extra part
you need. Some of them even will have a lot of nice timberwork that could be
used for other projects as well. Hope you don't have a fabric aircraft in
you hanger when you pick them up 'cause it will take a month of Sundays to
sort it all out!

Hope this helps,
Peter
