Wouldn't a dremel eat away too much metal? I've heard people talk about a jewelers saw. I wanna know where to get one of those at.
jeweler's saws in my experience (I am not a jeweler) work best with softer metals. However there could be some training I missed. I do however have like 3 of them.
Only cut so far w/ a wheel then sand from there. I use mine w/ plastic all the time and have dabbled with cutting metal as well. Actually, I have to do more sanding w/ the plastic. W/ the right cutting wheel, you can get damn close to where you want to be on a piece of metal.
Wreckgar: Go to a hobby or craft store and pick up a razor saw. Get the coarsest tooth one they have -- die cast is a soft metal and likes to clog tools. A good-quality hacksaw blade of about 32 teeth per inch is also good, but leaves a thicker saw kerf than a razor saw will. A razor saw is about $3 and fits in the big red Xacto knife handle. Jewelers' saws are good if you need to cut curves. I haven't ever used one, but they say the blades break easily. I presume you are cutting apart a die cast model to make a TF from it?
I will make use of this information to complete a kitbash I abandoned due to only being able to find a die-cast of the car I wanted to use....
I second the razor saw comments. They cut very thinly. I use them for my 1:285 Battletech miniatures and I hardly lose any details. (And yes the jewellers saw blades break very easily.)
