Here is my Drill Holder made from a piece of 2x4 rectangular aluminum tube.
Its all set up, for tap drills, along with the associated close and loose fitting
drills for the body of each size of screw.
It also has places for various sizes of countersinks.
I have thought about this project for a long time, finally got around to building it.
In my opinion this is way better than any chart, were you have to look up
each size and then select the proper drill.
Combined with the drill rack mounted on the other side of the drill press,
I should be able to do about 90% of what I need to do with out ever
looking at a chart, or searching for drills.
Rarely, do I ever use any fine thread bolts, so no sizes are included
for them other than 10-32.
I painted the ends of the drills to match the colors on the label below.
This concept could be adapted for all sorts of holders, for other tooling as well.
Should give you some ideas....
A groove was milled into the aluminum for the labels to set into.
The labels are made by printing onto photo paper, and then placing a plexi-glass cover over it.
The plexi is held in place with three 4-40 stainless steel, button head capscrews. (using the proper name here)
I used a piece of 3/16 thick x 3-3/4 wide cold rolled steel for the center divider.
Its bolted to the aluminum tube with four stainless steel button heads.
I drilled through both layers at the same time.
Once the drilling operation was completed, the center divider was un-bolted
and all holes were chamfered with a countersink.
Thats a 10-24 bolt extending from the back, to keep my smallest countersink
from falling through, as its shank is not long enough to reach the back of the
aluminum tube
Here it is mounted on my 1955 Walker-Turner.
The hole at the top right is for a future 1-1/2" countersink when I find a good deal for one on E-bay.
Thats a standard Huot fractional drill stand mounted on the other side, and
has been that way for 20+ years now.
Shot taken from the bottom, looking up at the ceiling.
Center divider is 1/2 longer than the aluminum tube to add a little space
between the drill press casting.
Another small piece of cold rolled was TIG welded to the center divider
to form an angle that was drilled for two 1/4-20 button heads which
hold the whole unit in place.
I think its going to be a lot faster/easier to drill for bolts now.
