This instructable will be showing you how to make a hacksaw from a piece of rebar.
Step 1: Designing The Frame
First draw out the design of the hack saw frame.
Step 2: Shaping
Now heat the rebar and bend until you get the shape you want.
Step 3: Cutting Slots For You Blade
Now get a cutting wheel on a grinder and cut a slot on each end so that the blade will fit.
Step 4: Drill Holes
Now drill holes for the bolts that will hold the blade in place.
Step 5: Welding The Nut On
Now weld a nut on one side.
Step 6: Putting The Blade On
Now this part is important. Because if you don't do it right the saw will not work. In order for the saw blade not to bend or flex while you try to cut a piece of metal you have to keep tension on the saw blade. So before you put the saw blade on you need to bend one end out a little so that once you bolt the saw blade on there will be a lot of tension on the blade.
