I've never been a big fan of Gandy. They were alright tables but seem to always be a pain to move. The rail bolts go in real rough. And there always seems to be alteast 1 stripped one in there. And the slate just feels weird to me. Almost wrinkled.
I worked on a Gandy today where we thought we were going to have to grind a bolt down to get the cap off. And 1 of the peices of slate was I think 15/1000ths of an inch off on 1 side. Perfectly level in the middle. And 10/1000ths of an inch off on the other. It was basically a U. High on both sides and low in the middle.
