Hi everybody!

There's a lot of work going on here on aircraft 2d panels, MVG and I are involved in some of it.

Yesterday he brought to my attention an historical fact that I want to share with everybody here, it's very interesting.

http://www.acontinuouslean.com/2013/04/05/a-better-way-to-screw/

Philips-head screws were not present on German and Italian aircraft of the 1930's. The blueprint shown in the link above indicates they were US-patented in 1936.

They were not seen in Europe before 1940 and, here, they were first seen on US-made vehicles and aircraft.

This makes instantly obsolete any 2d panel made for Luftwaffe or Regia Aeronautica birds, I believe even French or Russian airplanes, showing gauges installed with Philips-head screws. Regular slotted screws should be seen, instead.

Before yesterday, I would have never imagined it. It also goes to demonstrate what level of aviation history knowledge Manuele Villa, a.k.a. MVG, possesses.

A couple of pictures, from the desk of MVG3d, shoving both the slotted screws and the amazing detailed glass-reflection eye-candy he's capable of.

Soon to be released.....

Cheers!

Hello Kelticheart,

I knew WHY Phillips Screws were invented but thought they were invented a bit later.
This issue comes up often in gunsmithing with older guns which simply don't look right with Phillips screws.
A Percussion Gun or Flinchlock simply doesn't look right with Phillips screws.

I'd think an old gun would have pins or the old blacksmith rivets. When were screws in general invented?

I don't go back any further than Flintlocks but I am pretty sure that even as far back as Matchlocks, guns were assembled with screws.
From my own aesthetic viewpoint, Phillips head screws just don't look right on a gun though you find them often enough in modern guns.

You know I never thought they went that far back. I figured maybe late 17th century at best. At least a type like we might recognize.

Now THAT is a very curious thing. I have actually never fired my own Flinchlocks though I have fired plenty of others.
It just doesn't seem safe to be priming the pan with a slow match a few inches from the powder.

It is pretty obvious that the flint would be held in by a screw mechanism. What could also be seen on the opposite side of the gun would be where the lock is typically held on by two screws.

Thanks for showing such an odd thing.
