It was supposed to be free shipping but I just got the invoice and there is a $10 and change charge so it worked out to $177 to the door. It has not shipped yet.
Extra smaller pulley?? good question... I don't know. I have a couple of pulleys that I tried on the clutch motor. These have .75 in. bores so I will have to come up with a bushing. Apparently the servo has a metric shaft so possibly a 5/8 bore pulley could be bored out. Not a big deal for me. I can see the extra mechanical advantage of the smaller pulley but I really don't think it is necessary. Just because someone said the clutch motor would sew thru plywood I tried 4 layers of vinyl and a piece of 1/8 aircraft ply and asside from a horrible noise it didn't even slow down. It did cost me a needle. The servo is supposed the be even more powerful.
Actually I'm trying to get to the skill level that I won't need the very small pulley. Dan advocates just using the hand wheel for tight spaces and I'm already comfortable with that. It will be nice to be able to poke along at my own pace instead of the zip, stop, zip, stop that the clutch motor requires.
