First post on here, great site

I am looking to build a CNC table for my shop, I am not looking to break the bank with this machine. I like the cost factor with the oxyfule and it fits more to my needs. The material I will be cutting is 1/4" and 3/8" it never changes, I dont plan on doing any sub work, I am trying to keep my work in house. I am not concerend with speed either. What ever maching I build will probley be only used maybe 6 hrs a month.

I am looking to build a maching with a cutting capicity of 4'x4', I plan to use round lineir rails for both of my X and Y axis not sure what the best drive system to go with rack,belt or screw. I would like to do a single side drive on my X just to keep cost down. Now the question shopuld I go with plasma for this set up or the oxyfule? I have the torch set up now I would have to get a machine head but other that that I am 1/3 of the way their.

Any advice would be of great help I am new to this but have been intresed ig doing something like this for a wile.
