Homemade circle jig for plasma oxy cutter invention tool
I decided to build me a homemade tool invention which is a quick circle jig for my Powermax45 plasma and oxy cutter. I am cutting out some lids for some small BBQ grills as a test. The circle jig invention tool works great when doing lots of cuts as it holds the size once the nuts is tightened up. This invention seems to do the proper job and will be added to my tool box of homemade tools The Circle Jig tool could also work with a oxy cutting torch with minimal modification. This invention / tool is something to add to my Plasma Cutter tips and tricks. The circle jig tool can be made for under $14.

$5 Magnet'
$3 All Thread 1/2"
