Now with the material being fairly thin, I suspect I will not see much of a problem with the larger holes, however My question is, how precise with the smaller diameters be?
Thanks Alot guys

I am not currently a plasma user on my CNC table. I am however using Ox/Fuel on thicker plate 1/4" through 1" I can cut down to 1/2" holes that are very near drill quality holes. I can cut smaller diameter holes but get lots of rounding of the top edge from heat. Although the plasma stream tends to wander a bit as the cut process tales place you should be able to burn fairly small holes. Not sure if you can achieve good success on the 3/16" holes. I guess it will depend a bit on the accuracy you need between hole centers on bolt patterns.
If it works.....Don't fix it!
