DH.2 F.E.8 Lewis gun mount
« on: October 09, 2019, 06:31:45 AM »
Woodman's excellent Early Aircraft Armament book* has reproduction of a document from 1916 listing the guns and mounts for different aeroplanes. On page 248, the De H.2 No.4, Mark II. has a note: 'As in F.E.8'

I haven't been able to find a picture of the early DH.2 'wobbly mount'. Has anyone got a picture of the early mount on an F.E.8?

It may be: 'Rising pillar balanced by rubber and locking knob, no arm. With clamping handles for elevation and traverse'

Can anyone help with this?

Richard

OK, I was looking with my eyes closed

The mount is on page 52/53 - On a DH.2 and a F.E.8

Apologies

It's worse than that - the 'wobbly' mount is on page 50...

And finally....

The aeroplane I want to model probably has the later mount, which is in the Datafile

Research, huh - who needs it!

I've had a go at modelling the 'wobbly mount':













It gives all the range implied by the drawing - I haven't tried to model the knob attached to the sliding post, the knob is probably a bit big too. Buried in the cockpit of a DH.2, it's good enough

It's a frustrating bit of kit as a model. The arm rotates, the gun rotates on the arm and pivots up and down. Th only way of keeping it straight ahead is a tiny bracket which still allows the muzzle to slop from side to side. No wonder pilots complained

Cool work, Richard. A model of it's own.
Bye,

So, armed with my own tiny wobbly mount, I have worked out how the damn thing was mounted in a DH.2. Naturally, the solution was staring me in the face

Using the image from Woodman's book, and the drawing from the Windsock Datafile, I have this:



The patent drawing obviously shows a DH.2 and it scales out perfectly.  The problem is, according to photos and drawings, the gun should sit further back in the cockpit than with the RFC mount. But it doesn't:



It actually sits a lot further forwards. Using my model of the mount, I think I have solved the conundrum. If the gun is mounted properly, it sits well forward:



But if a pilot reversed the top arm, it sits well back:



And that looks like the correct position shown in photographs

Why would a pilot do this? Well, in this position, a pilot could either strap the swivel arm to the gun stock support, eliminating quite a bit of wobble, or strap the whole gun down onto the arm and stock support, locking it up completely

This sounds exactly like what a pilot might do, they would only need a leather belt
