I recently purchased a Hypertherm 30 and have a few projects in the works.  But, I need a cutting table / grate for these projects. I don't have the garage room or the flooring for cutting in the garage, so I needed to design and build a cutting grate that is portable and easy to set up when needed.  I have a few sets of steel saw horses that I keep outside so I thought that would be a perfect "table" to place the grate.I fabricated the grate so the top of the verticals were level with the angle brackets that capture the horses.Can't wait to start cutting!
Reply:Slick idea with the metal folding saw horses. Very portable. Good job.

Reply:Looks good. Nice idea
Reply:If I made one of them I would likely knock into one of the saw horses and drop that grate on my foot. Why not make the support tabs a bit wider to span the width of the saw horses and then with a downward bend to provide a hook to keep the saw horses from being knocked out from under it. Dropping it on your foot would be very painful.CharleyMiller MM252Miller Bobcat 225NTMiller DialArc HF / DIY Cooler2 Victor O/A TorchsetsMilwaukee 8" Metal SawMilwaukee Dry Cut "Chop" Saw 5 Ton Wallace Gantry Various Grinders, Benders, etc.
Reply:Nice idea.  I would add that if you had lengthened the cross pieces and made slots in the vertical part of angle (easy to do with chop saw), you could have removable slats that first can be turned over when they get cut up, then replaced as needed.  My table gets pretty sliced up in the center were lots of cuts take place.  A bungee wrapped around it all would hold it together when leaned up against the wall for storage.  But then again, maybe the slats being loose would be a bigger pain than it's worth.Really like the portability.  In good weather I could do all my cutting outside and leave the mess out there instead of coating everything in the shop!

Reply:Originally Posted by anickodeIf you look closely, you can see the grate is bolted into the sides of the saw horses.  The bolts are just visible in the corners.
Reply:You could weld pins to the bottom of the tabs and drill holes in the top of the saw horses for the pins to drop into. Also be careful not to cut into your saw horses when making long cuts. done that with my skillsaw before then I look around to see if anyone saw me do that.
Reply:Yeah you definitely want to secure the horses to the table somehow.  I have a similar set up as a working table (using a pair of old trailer ramps) as it is all I can fit right now, and knocking the table off the horses is a big problem, especially when dealing with heavy or awkward items.  You could possibly just turn your L-brackets into C-brackets that hook over the back side of the horse tops.  It wouldn't secure it from all possible movement, but would help a bunch.-DaveXMT304 with: 22A Feeder, or HF251 Hi Freq DC TIG air cooled
