4x8 Plasma Table parts

[Nfabworks]

Hey guys,
I have been lurking for some time now and finally started getting my parts togather. I am for the most part copying Dnelso's build. Before I amke a costly mistake I would like to get some inputs on some of the parts I have chosen. And I am a newbie so if I ask a stupid question, that's why!

Here are the parts and prices I have been quoted so far, as well as the source.

Steel for the build will be around $600 and I am making the table 9' x 5' so I can come off the cutting area a bit.

If the space is blank that is because I havent gotten that far!

I have a few questions. I am looking at Anahiem Gear for a reduction unit. They are high priced but still within the budget $250ish for the direc drive and $500+ for the 90deg. angle.
The problems I am having is the gear reduction ratio to get and the resolution change due to backlash. There inline unit stated a backlash of (12 arc-min) and the 90 deg. unit is (22 arc-min) are these acceptable #s for Plasma? Also the torque ratings, everything I read is showing a 3:1 reduction is the best?


I am hearing 20* pitch on the rack?
Thanks for the help!!
