By half an inch. There were too many lines drawn on it, because I had a hard time getting them off. And I starting cutting from both sides rather than going straight through from one. So now one side is cut half an inch lower than the other, and is too short. So I'll have to trim some off of one side, and keep in mind the half inch difference while I work on the rest of this thing.

My God! are you cutting that all the way across with the Dremel?
With the money it cost for all those cutoff wheels you could get a Jigsaw.

You may want to use a fine tip Permanent marker instead of a pencil.
I'm no expert :) . .But it looks to me like your going about it the Hard Way.

I have a jigsaw attachment for my Dremel, as you can see here http://www.thebestcasescenario.com/forum/showthread.php?t=10008


The problem is right now I don't have anything to put the whole sheet on to use the jigaw. So I worked on the floor, using the cutting discs. On some of it, I just scored it and then bent it off. It also doesn't matter what these edges are like, as they won't be visable at all, and it won't affect the structure.

The reinforced cutting disks will last quite a while. Can get through that with about 3-4, at about $1 a piece in the bulk pack.

That sucks, were you able to salvage it?

By the way where did you bought the aluminum piece?

Well I added half an inch to each side so I could bend it up to rivet the sides to. But I planned on putting one side on hinges so I could open it up. So after looking at the design, it really turns out to be fine, since I don't need to rivet the side with the door, so I don't need that part bent up. And I bought the aluminum at a local place.

i'm thinking about buying this (http://cgi.ebay.ca/10-DIAMOND-SAW-CUT-OFF-DISCS-FOR-DREMEL-ROTARY-TOOL_W0QQitemZ320148641568QQihZ011QQcategoryZ34087 QQssPageNameZWDVWQQrdZ1QQcmdZViewItem) kit since i ran out of reinforced discs.

Diamond discs do not do good at cutting metal. They're more for glass and stone and such.

Those reinforced ones are good. They're made from carbon fiber. And I suppose you could use the diamonds ones for acrylic, but the emory or reinforced ones would work too. And you can get special ones for cutting plastic. I've used diamond ones on acrylic though, and though do go through it fast and fine, as well as other plastics. But through metal, not so good. They're like a steel disc coated with diamonds.

I'd agree there. I have several diamond disks, and have very successfully used them to cut thru several kinds of plastic (for modeling miniatures). They worked OK on my pewter, but it was a lot harder on them and the reinforced disks did better there. The only real benefit of the diamond ones in that instance is the thinness of the disk, if material retention on both sides of the cut was an issue.

lol. I did it with tin snips. Works better than [insert evil pointy object here]. Just takes some elbow grease and headlight fluid.
