Enco, sells 3' pieces of both water- and oil-hardening drill rod
in all sizes. Fast shipping. Prices are reasonable. If you buy $50
or more from them shipping is free:
In addition to the mentioned catalog houses, McMaster, MSC,
ENCO....I think maybe even Grainger...
A lot of local based industrial distributors will stock the O-1 and
W-1 drill rod...usually fractional sizes...i.e. 3/32, 1/8, 1/4, etc. A
3' section is not expensive at all...
As mentioned, the stuff comes annealed, and if you have a gas stove
in the kitchen, one can heat treat most of the smaller sizes...
To temper (final harden) it, or do a draw as I seen it called....a
toaster oven will even work... I suppose a regular oven would work
