I wish I had seen previous reviewer's post about Woodcraft before I bought this one.  After spending an afternoon trying to rig various fittings to this thing I finally decided, no, I'm not going to have another duct tape covered Rube Goldberg eyesore in my shop.  And so now, after paying $9.00 shipping to get it here and $17.00 to send it back, I purchased the Woodcraft product and paid whatever it is they charge for shipping only to discover that the same item is now offered on Amazon with free shipping.  Color me pissed.
