I would like to know what type of material to practice on other then alumunium, to keep cost down on my 3 axis cnc mill?
Any advice would be greatly appreciated!

Thank you,
Jim Mill

Bar soap for small parts, 4x4 blocks of wood can be used as-is or glued together for larger "billets".

Thank you for your quick reply to my inquiry,
I will try all that has been suggested.

Thank you,

MDF is perfect, wax is another or just do it in aluminum and maybe you,ll get lucky and get it right the first time.......:devious: http://www.cnczone.com/forums/images/smilies/devious.gif

ZipSnipe, I think that I'm leaning toard MDF as I have so many parts to prototype. ( Measure twice cut once or something like that ).
Thank you for your quick response to my inquiry.
Have a Happy and Healthy New Year!
