John, the steppers are Motion King 34HS9801 ($55AUS each) and the drivers are Model 2LA860 ($95AUS each). I am extremely happy with both purchases. I had inititially thought about a geared belt drive, but find the resolution with direct drive quite impressive, and more than sufficient for my needs. I will post some more photos of the MM doing it's job, but later.

Here are some photos to show that my mechmate is not totally idle. The loo signs are in Gaelic, The Dory seats are ordinary C/D grade plywood that is finished with Stain and Varnish, The Scottish family crest is MDF also finished with Wattyl Teak Stain and Varnish, The serving tray is Merbou and cut with a cheap V bit that loses it's edge too fast. Also got off my arse to update my website, will update it again to showcase another invention. Link is http://jude.idx.com.au/

the cd ply boat deck turned out very nice

I thought my work commute was bad at just over 35 miles one way, but atleast I dont have to row to the mainland. :D How do you see over the top of those big fans to steer the hovercraft?
