Has anyone used Plasma to Mod a case?

[tinker dave]

I have a Miller Plasma cutter and was wondering how it would work on cutting out patterns on cases.The problem I have allways had with it is that it very hard to hold steady. Other then that it cuts very fine and fast. Any thoughts on this subject?:) Thanks.

The cut may be fine, but the edges left by a plasma cutter are typically very jagged. Alot of filing would be required. It would be difficult to end up with a perfectly round hole IMHO. It's kind of overkill if you ask me, unless of course, you posess some "mad plasma skillz".

A properly set up hole saw, jigsaw or my personal preference, a dremel cut are the best bets.

If you decide to try the plasma, keep use posted (with pics) on the results, good or bad, so everyone can see.

Good luck!

I did some of the sheet metal work on my last case with a plasma cutter since I don't have a shear. No matter how steady you are with the plasma cutter you will have an edge that needs to be ground off if its a cosmetic part. Not that that's any reason not to use it. If I were going to cut my case i'd make some templates, cut the parts, and take the edges down with my die grinder.

The only time I've seen plasma make a clean cut is on a CNC machine.

Guys, Thanks for the insight.

Even then, you're going to have some slag on the backside.
