Pipe Cutting Jig attached to a 2x4

thingiverse

I recently had to chop identical lengths of 12-1/2" EMT (Electrical Metal Tubing) so I came up with this easy holding bracket attached to a 2"x4". I am using a Rigid 101 Tubing cutter http://www.homedepot.com/p/RIDGID-101-Tubing-Cutter-40617/100075014 . I built the bracket so it was a snug fit against the cutter. I printed three brackets for the size pipe I was using and an EMT_Cut_Jig_8mmSpacer_Rev4.stl file. I only needed the third bracket when the pipe was really long. You need one 2"x4" slightly longer than the pipe you are going to cut. The second 2"x4" can be relatively short. I also used a small 1"x2" screwed to the end of the 2x4 so the pipe would butt up against it as shown in the photos. As the photos show, I marked the 2x4 where I wanted the cut to be and used the 8mm spacer to get the location of the bracket and used wood screws on hand to mount the bracket. Once the two brackets are mounted, it is then very simple to attach the cutter tight in place and remove it from the brackets to cut it. When removing the pipe to cut, it is better to pull it away from the end before pulling it out so it will not scar up the 1x2 board at the end. I included a customizable OpenSCAD file so you can make a bracket for most any diameter pipe. You could also use this for other pipe cutters; you'll just need to measure it slightly differently. There is a dimensioned image that shows the variables you might want to change in the OpenSCAD file. I made an STL file for the three main MPCNC style machines.
