Will someone at Home Depot or Lowe's be able to cut this for me? If not, what tool should I buy and use?
Edit
Thanks for all the help! I ended up buying a Dremel. I went through 6 cut-off wheels in order to finish all my cuts. I was customizing an IKEA drawer to fit under my smaller IKEA table. Here is one of my noob cuts:
And here is the finished product:
Best Answer
Hacksaw
Lots of work. BORING!
Oscillating multi-tool or Rotary tool
You're probably not cutting 1/8" steel with this, but it's useful for cutting very thin metal.
Jigsaw
A little more fun, but still a bit tedious. Make sure you use the proper blade.
Reciprocating saw
More fun, but you may have trouble keeping a straight line.
Angle grinder
Let the sparks fly! Lots of fun, and it will allow you to plunge cut.
Torch
An Oxy-Acetylene, or Plasma torch will make short work of this job.
Punch press
Finish the job with the press of a button.
Lightsaber
Fast, but requires a bit of Force.
If you're using any of the saws, make sure you use cutting fluid to prevent the blade from overheating.
