I am building some small (5"x8") gift boxes out of small scraps in the shop.
Some of the boxes have hinged tops and I am using some small brass hinges
from LV -- the hinged use a #2 brass wood screw.
The latest box I am trying to finish is made from Honduran Rosewood -- a
beautiful, but very dense wood. I am predrilling holes for the #2 screws
using a 1/16" bit to the depth of the screw which worked fine in the
Mahogany I was working with earlier. The Rosewood, however is a bit more
fickle and I continue to snap the heads of the screws.
Anybody know any tricks to make this work ? I know about using a steel
screw first to define the whole but I do not have any #2 steel screws
Then use a #2 STEEL screw to cut the threads, then remove the steel #2
and put in the brass #2
If you don't have any #2 steel screws, maybe a run to the hardware
store is in order???

Many many years ago in high school shop we were taught to take a drill
bit and lay it along side the screw we wanted to pre-drill. When we
could just see the bottoms of both 'V's over the thichness of the bit,
we had the correct drill bit to pre-drill with. Don't know if thats a
1/16th in your case or not but its always worked for me.
Try some of the wax from a toilet bowl ring on the threads. Works great
and one $1 ring will last years and years.

Probably not. Since the machine screw has a different thread form, turning
a tap down the hole will attempt to cut the machine thread. When you
attempt to follow this with the wood screw, it would be like attempting to
thread a 10-24 screw into a 10-32 nut.
About the time I had mastered getting the toothpaste back in the tube, then
youre kidding me, 14.5cents for a small screw? even in stainless is
ridiculous... were those 2.60 for the 3 ought?... wow... wouldnt wnat to drop
those in a crack... if you used 3 or four of those in a hinge, it would be more
than the hinge.. holy crap...
McFeely's stops at #4 too, looks like.
So I'd try:
* use a slightly bigger drill bit
* lubricate the threads with Johnson's paste wax; drive while still wet
How big is a #2 screw anyway? I haven't really learned screw sizes, since I
usually just use the screws that come with my crap BORG hardware.
What I'm thinking is, might you not find a suitable screw in some little
toy, or a computer? I can think of lots of little steel screws I've seen
along the way, though I'd guess it's probably unlikely any of them have the
right thread pitch for wood.
