American 7260 crawler crane

I think that most of us using those types of machinery have either access at work or contact a local company. I have had a couple different companies heling me ($$) depending on what type (thickness) the part will be done from. I have used the laser cut parts because it give me an acurance that I have problem to achive. I don´t have any education on metal working so every step is big for me. But , yes it´s a dream to have a small laser, but hard to see that coming. Maybee a CNC mill is closer (i hope).
Eef, a question about that EDM, it looks like a wire between the heads, how do you get that wire into a hole? And isn´t there another machine that can partly cut through a plate to get difference in height??

Hi Dan

The wire is shot in with a small but powerful water jet ( you need a small start hole )
The water jet acts as a guide for the wire and it keeps it perfectly centered.
The wire goes done with jet while the machine slowly feeds the wire.
On this machine i used 0.25 wire but 0.1 or 0.05 mm wire can also be used.
Don't know exactly what you mean with the second question , make me a simple drawing so i can answer that one.
here is a nice youtube that explains a lot
