Hi, I'm starting to buy stuff for an extruder, Tommalise style. I've got most of the materials I need, and I'm just wondering if anyone has found a good source of nichrome wire? I'm located in Ontario, Canada, but I suspect I'll have to order from the States. Er, that's Canadian speak for the US. ;)
I have an order just about to go out to DigiKey, but of course they don't seem to have nichrome there.
BTW, I think I'll be focusing on extruding ABS plastic, it seems to be closest to what I need.
Thanks for any leads!

If you are only going to make one or two extruder barrels give me your address and I will send you along the 15 inches or so to do the job in the post. I can be reached at fshiggs@yahoo.com.
I'm a little worried about your using ABS at this point. I've got filament for the job but the stuff is right at the edge and maybe a little bit beyond the edge of what my Mk 2.1 can handle. HDPE is working fine and HPP works pretty good. The Mk 2 polymer pump body just doesn't seem to be able to put enough pressure on the filament to pump ABS as well as it ought with the springs I have. I have to use a clamp in addition to the springs to make it work. I'm going to be making a beefier polymer pump for ABS and HPP out of HDPE as soon as I can get Tommelise printing well enough to do multiple layers.

Thanks guys! I'm seeing lots of 50ft spools, for around $20+ US plus shipping. ;) Forrest's offer seems very good right now!
Now about the ABS. I noticed it is at the limit viscosity/pressure wise, but my strong point is fabrication. (That and 3D modeling I suppose) Building a few assorted prototypes is not a problem. Schedule wise I should now have some time available in the evening. :)

YvanRoy,
I get mine from a crowd called Pelican down in Florida. You can get the website for the nichrome from the Tommelise website at...
