The time you will save and the accuracy will more than pay for it. Bob Perkinson Hendersonville, TN. RV9 N658RP Reserved If nothing changes Nothing changes Only vaugely rotary related... I'm driving myself nuts trying to build this thing level to within 1/8 to 1/4" ! I'm using a gardenhose, terminating in clear PVC tubing at each end, to get reference points at the four corners. The thing is that the level varies 1/2" or more over hours. One end will be up, 1/2" over where it was an hour ago and the other end down. Then it changes, etc. How can a guy get a reliable reading this way? Is the friction in the hose too big to reliably use this as a level? Do I need to terminate each end in funnels to get bigger ambient pressure? Finn (frustrated)
