I am at it again, I am making a tubing tool to put in droplines into the laterals.
I have the handle part done and the top part that will hld the 2 visegrips. My idea uses 2 6" 5/16 bolts to keep the visegrips parallel to one another. You can see it in the pics below.
I am thinking of adding a spring to pull the handles together so that once a place a fitting between the ends of the tubing I will not have to have a 3rd hand to squeeze and hold the fitting. we'll see.
It took a little calcuting to get the distances from the central pivot to the ends to get enough travel that I had room for the fitting between the tubing.
I will post more pics and also the design plans, they are on my other computer, once I work on it tomorrow.
