A while ago we built an outdoor fire pit, we've wanted to be able to grill on it, but grates that either fit our fireplace or were the right one we wanted were too expensive. I rescued the grates from an old gas barbecue and fabricated a better grill than you can buy!
Step 1: FIND YOURSELF SOME GRATES!
Here are grates I used, I took them from a big gas bbq we were getting rid of. You can use anything you find or buy that will put up with open flame.
Step 2: PLACE THE GRATES
Whichever way makes you happy. I ended up pushing the grates together for one large surface. Use a Sharpie to mark the rebar where you will want to cut it. I moved the whole thing around quite a few times until I figured out how to place the grates on the rebar in such a way that I can move the finished contraption around on the pit and NOT have rebar sticking off of the edge of the pit! OUCH!!
Step 3: ATTACH REBAR TO GRATE PHOTO 1
It's wise to attach before cutting. I used 1" diameter hose clamps to attach the rebar to the grates. Whichever ones you use, they will need to be skinny enough to fit between the grate bars, and long enough to stretch around. I kept them loose until I was happy with the placement.
DISCLAIMER!! I don't know if these will disintegrate in fire, immediately or over time, if they do, I'm going to get some stainless steel wire to twist tie them together and will update.
Step 4: ATTACH GRATES TO REBAR PHOTO 2
Here's a photo of how I used the clamps to attach them together. The clamps can be tightened with a flat-tip screwdriver.
Did you make sure to place the rebar so no one will bump into the ends??
Step 5: CUT THE REBAR
Use a hacksaw or angle grinder to cut the rebar.
Step 6: FILE DOWN THE ENDS AND ENJOY!
After you cut the rebar, use a file to smooth out the ends.
