It's a bit overkill for just running a single motor, but useful if you want to drive more stuff.

Yes I know but found it cheap,

http://www.ebay.co.uk/itm/Arduino-Special-Motor-Drive-Shield-/280531168628?_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D5%26po%3DLVI%26ps%3D63%26clkid%3D2539622117301841963#ht_3396wt_1139

I can use it for other stuff too.

Cheers

Yes as I said before you might struggle, the key is getting a rod with a small number of TPI (threads per inch). The CD drive as a very spaced out thread on the spindle. I am not sure where you get these from.

Hello Jim, I sell linear actuators as part of my job , that speed you require is very fast, and you will have a hard time finding anything , you would have to go to a big linear actuator. even then they have a 10% duty cycle, this means you can run it for 10 minutes and then needs a 1 minute rest to cool down.

Ok, maybe I could half the duty cycle by doubling the motors, one moves one way then the other moves it back?

I looked at maybe using a rotating action into the linear but I think that the mechanism would be too big?
