Carpenter has been at the top of the list for decades, but there's a long
Another place as good is udderholm, and there's no waiting list.
I would make a soft core every now and then, and the first thing I would
do is throw it up on a dedtru to clean it up, and if it wasn't banged
sitting on the floor in shipping I swear it would take a couple of tenths
tops till it cleaned up. That was crs, hrs, and tool steel.
The esr steel literally would have no imperfections whatsoever inside.
Pretty amazing considering the bars are 8 feet long/
Just what tolerance do you think you need?
I use Fry's material in my Swiss almost daily.
Their material is +/-.0005" I hold .0002" with their material. Hell, I
hold +/-.0002 with cold drawn material!
The tolerance isn't really what's most important. What really matter
is that the bar is straight, and round.
What makes you think you need better than +/-.0005"?
D&S Wire, in Chicago.
Their prices are OK. For the +/-.0002" shafts I was running at the
time, the cost difference between turning Fry's material, vs. feed &
cut-off D&S's drawn material, didn't really lean in my favor until
quantities got over 10K.
IIRC, their price for drawing it into a coil, to run in an Escomatic,
was quite good. Straightening and cutting into 12' lengths is where it
began to wash out.
In March '08, they had a 3 week lead time. My customer only ordered
10k pieces and I was able to turn the parts from oversized material,
and deliver them, in less time than that.
However, if this customer ever gets production up to the 50k pieces he
originally had me quote, I'll most likely go with D&S.
