In addition to 2 of the LOAC tools, I also own a Line Viper. I find it works well but is heavier to carry than a LOAC 2 hand. I also own a LOAC 1 had but far prefer the 2 hand.With all of those, both my BIL and I tend to use my original 1 hand tool for repairs, it fits in a pocket and is less bulky. The one I use for that is a simple design, but it only is designed to work on 5/16, I carry a split piece of 5/16 to slip over the 3/16 to use it. I just looked but didn't see one like mine. It is built on a large size slip joint type pliers frame, but is not slip joint. When I open the handles far enough it opens a clamping jaw, as I squeeze the handles it tightens the clamp and pushes the end of the tubing towards a flat section with a slight curve and a slot in it. If installing a connector or T the opposite part extends thru that slot. It also has a low tech cutter on it but it still works well. I think this was the first tubing tool I ever got in about '04. Before that I used a thermos full of hot water.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
