thanks, it was a lot of work...but my dad's a handy man actually, all the home-made stuff works great, the bought stuff a little less (I need to back up my fixed clamps, and the gripper needs a peice of cardboard) works like a charm though
I got a package deal for the clamps/rails/linear gripper at www.powertennis.nl it's the dutch retailer for pro's pro, and I'm contemplating getting some good fixed clamps...Either they slip, or crush the string (no breakage at those points yet, but it looks nasty at the start) and I'm constantly re-adjusting them because the adjustment screw slowely back out the clamp...
Ohh I see. So they're pretty much Eagnas clamps. Yes I'm in the market for some good badminton clamps myself. I really like the rounded ones that Eangas copied from Babolat, but I've heard enough consistently bad stories to keep me away. I can't seem to find any information on where to obtain genuine Babolat ones or the price (I'm sure it'll be a hefty one).
