I present to you, the twist drill.
A
modern day version of what was a relatively new tool developed in the
1860's. A rather unassuming tool, and mostly taken for granted in the
21st century although it is used in manufacturing
everything today from the car you drive to the chair you are sitting
in now. Yes, the lowly twist drill, so taken for granted, so much
ignored, so, so... boring! (pun intended!) But without this little
keystone of modern industry, this may not have came to
be:
That
of course is the very Confederate ironclad ram built in a cornfield
along the banks of North Carolina's Roanoke River in 1863 and early
1864. The same ironclad which was largely designed by Gilbert Elliot,
a native North Carolinian of 19 or 20 years of age, with the help of
John L. Porter who would polish the design and bring it to fruition.
She was the monster that aided Major General Robert F. Hoke in
re-capturing Plymouth, North Carolina which surrendered on April 20th
, 1864. Without the Albemarle that would have been nearly impossible
although Hoke's men outnumbered the Federals, they were well
entrenched and had five US Navy gunboats in support. The place would
be a tough nut to crack indeed. All of this is interesting but what
has a drill have to do with all of it?
Gilbert
Elliot had difficulty obtaining iron for the “skin” of the ram
and would finally get his hands on some in the Autumn of 1863.
Framing of Albemarles hull was completed in early October, and on the
6th, Albemarle was launched, sans armor, into the waters
of the Roanoke River, which happened to be running high at the
time.[1]
With
the beast in the water and iron ready to hang, the work to transform her into an engine of war began. The problem was that the
armor plates had to be pierced with a number of holes, one and a
quarter inch in diameter, so they could be mounted to the hull and to
each other. This was not an easy task, and it would be time
consuming.
In the Spring of 1864 the
Confederacy did not have time to waste.
As Gilbert Elliot puts it ,
in an article in “The Century” magazine:
“But
one small engine and drill could be had, and it required, at the
best, 20 minutes to drill an inch and a quarter hole through the
plates, and it looked as if we would never accomplish the task.”
Discouraging yes, but work continued. Now enter our subject, just now
being devised. Elliot continues:
“But
'necessity is the mother of invention', one of my associates in the
enterprise, Peter E. Smith, of Scotland Neck, North Carolina,
invented and made a twist drill
with which the work of drilling a hole could be done in four minutes,
the drill cutting out the iron in shavings instead of fine powder.”
[2] Thus the Albemarle was completed in the ensuing five and a half
months, and be ready for the fight at Plymouth. This is not to say
that the twist drill altered the course of the Civil War, but it did
make one episode brighter for the Confederacy at a time when
brightness was quickly fading into memory.
It is also said that this twist
drill was the first twist drill devised but that honor goes to the
Northerner, Stephen A. Morse of Massachusetts, who invented a twist
drill in 1861 and patented his design in 1863. But he was not
operating in a cornfield. Be that as it may, the twist drill is yet
another invention that came out of the “First modern war”, and
still has a place in society today even if it is in the shadows.
