Step 2Build the Drill Mount and Attach it to the Slide
Start by cutting down the Auto-Centering Drill Press Jig. We cut it down to a couple of inches high. This allowed it to provide a good amount of support for the drill, but still be short enough to clear the twist-on/off valve on the drill.
We removed the excess sides of the self-centering drill press jig, and sanded all the rough edges smooth. The THK rail mounts vertically along the center. We used the measurement between the holes to drill through the drill mount.
The holes are easily centered along the mount by drilling in the V in the center of the mount with a small bit, followed by a larger bit and finally using a tap and die set to tap out the threads from the back of the mount.
This is the most critical step of the process, the Drill-Mount MUST be in-plane and square with the Linear Slide.
We then attached the other side of the rail to a small section of angle-iron. We did this by drilling out four holes that I had previously marked. Get these as close as you can to square with the Linear Rail.
If your angle iron isn't square (ours wasn't), then use a square and a sander to square it up.
This piece of angle-iron will be used to mount our Linear Rail / Drill Mount to the Frame.

Do you think a piece of angle iron would work in replace of the self centering jig? I am trying to save as much money as possible

You say it's 30$, but in reality, you also need to get an air compressor, and a welder, etc. This could end up costing many hundreds of dollars if you have nothing but the parts for the drill press. Call back when you have one that doesn't need to be welded, and runs off of electricity.
