List has been real quite lately... or did I get dropped off? ;-)
TAP Holder:
Good idea's from Strictly IC (a magazine devoted to small "home
built" internal combustion engines) somone had a good idea of
keeping your taps seperated.
Simply a hunk of 0.6" thick alumimun: 1.5" x 3" drilled to
hold 24 taps: #0 to #8 taps (3 deep for tapered,standard,bottoming).
[all, but the #8 taps were the same size hole]
I Also made up two more: 2.5" x 4". One to hold the normal NC & NF
of #10, 1/4, 5/16, 3/8" (once again three deep in each section).
(F,P,W drill sizes were used).
Couldn't stop while I was at it: made up another one for my commonly
used metric taps: 6mm, 8mm (1.00 and 1.25), and 10mm (1.00 1.25 and 1.50).
[F & P drills were used, but SOME of my 8mm taps were larger than
others... so I made my holder to suit what I had]
Nice thing is this keeps the taps from rolling into each other (dulling
the cutting edge) and I KNOW when I am missing one. Much quicker than
searching a bench drawer each time.
[No reason wood couldn't be used... still you get the idea].
OTHER TAP THOUGHTS: I've found a new tap to sometimes make an
hold slightly oversized. Guy Lataurd (who puts out the "machinist
bedside reader" books) recommended tapping a hole into some scrap
aluminum, then coating the tap with some jewelers rough. Run the
tap in and out of the hole a few times, to remove any mfg burrs...
then it seems to cut a "normal" size hole for a better fit.
THREAD chaser for bolts: Tap a hole near an corner of a steel block.
Then cut 1/4 of the hole away - nearest the corner (hackaw will work
but I like using the milling machine for this). Clean the edge with
a file. Run the bolt in two or three times will nicely clean the
threads, leaving the "junk" to be easily brushed away.

use enough odd sized SAE and metric bolts to explain
why I eneded up with so many odd ball sized tap/dies)
Sigh... why couldn't they have kept Whitworth ;-) ;-)
