TIPS FOR USING PLASTIC HOT STAPLER & WELDER 

What I think. First, you have not yet completed the repair on the oil pan. As is, it's gonna leak. I believe as you use this device to do actual repairs. You may change your opinion. After you cut the pins off and grind them down, you are gonna need to melt some plastic down that crack, probably on both inside and outside. You may find it easier to do with the pins further apart. I believe that it depends on the project just which way you want to put the staples and also the thickness of the plastic. On some projects I would put the staples cross ways with space between so that i can staple from the other side also. Each project and how you are gonna want the completed project to look when you are finished will dictate how the best way to staple it is. Wouldn't mind seeing more videos as you use the tool more.
