Quick and easy cutting guide for a plasma

[PTsideshow]

I was looking around for a way to make up a cutting guide, for the plasma. When it hit me I could screw a couple of super magnets from hard drives that I saved when I was scrapping computers for the mortgage companies that went under.

Since I was just cutting out the good section of box tube from scarp I first tried using ½" ply wood and short wood screws. Next time I will use ¾" plywood and put through bolts and nuts as after 5 or 6 times of moving the board the screws pulled out of the board.

Cut only thing is it doesn't work good with the thin ply on the curved end I think the thicker material will help some.

Plus the added time saver/hassle of not messing with clamps! Posted Image

I will add something in case somebody reading this, doesn't know the plasma cutting stream can be affected by the magnetic fields of the magnets. Since I received a wild e mail from another forum  , about the dangers of it. I don't know that it will do anything other than effect the cutting flow or disrupt it if the magnets are to close.
I only use 5"/6" wide boards, and not the thin ones, placing the magnets at 3"s away from the cutting edge. I prefer the wider boards as they provide  a very nice surface to move the gloved hand holding the torch across the item being cut.
