Step 1: The Tools.
...Drill and bits (Bit size will be determined by the mounting hardware you choose)
...Marker or pencil
and finally (and most scary of them all...)
...A hand conduit bender (http://eaglemountainrentals.com/images/conduit_bender.jpg)
I understand not everyone has a conduit bender laying around...
...Many large home improvement stores have a tool loan program. Also if you have never used one of these I would suggest you purchase a few extra pieces of EMT conduit for practice. (it's cheap)
You will also need mounting hardware of some sort. The hardware you use will depend on how/where you plan on hanging the brackets. I used 1/4 inch toggle bolts, these say they will hold 185lbs. You'll find that in most case your mounting hardware will determine the strength of your bracket as the EMT conduit (thanks to the bends) will support much more than you think.
Finally I suggest adding some pipe insulation just to protect the items you hang on the brackets.
Step 2: Doin' Work
So... On to the manual labor.
Step 1 Measure twice, cut once!
Measure each piece to 30 inches mark and cut.
30 inches is a good length for most bends and general purpose hangers. With some practice you could use an entire 5ft stick and make some interesting hangers. (Sorta like the wall mounted garden hose hangers)
Step 3: Gettin' Bent
Step 2 Measure and mark you material. For 2 of my 3 brackets I used marks at 11 and 12 inches.
Depending on the size and shape you are hoping to end up with place one of your pre-measured marks under the index or start point of the bend and make your first bend. once you've got the first bend in, reposition the tubing in the bender and make any other necessary bends to complete the shape.
Step 4: Holy Wall Hangers!
Step 3 Mark and drill the holes.
Where you drill, what size you drill, and how many holes you drill will depend on the type of hardware you use to mount the hangers. I opted to use 2 toggle bolts per bracket. This will give me enough strength to use them for anything from surfboards, lawn chairs, and garden hoses to extension cords and power tools.
If you are using the insulation now would be a good time to slide it on.
Step 5: Hung Up
Total cost for all material = $15.00 (US)
