STARTING THE DECK...............

Image

The base is plywood and I am covering it with pine planks 2,5 cm wide, cut from tongue and groove wall cladding. This will then be varnished.
I have not yet decided on how I will build the ship's side as it needs to be strong enough to withstand the recoil of the gun. :) :)

Duncan,

I suggest a piece of aluminium angle along the base board and disguise it with thin planking both sides then continue above the anchor points with normal planking.

Yes, something like that, lost in a sandwich. The side needs to be at an angle if about 77º so 4 brackets might be better, one at each end and one at each side of the gun port?

Yes, Duncan, that looks a good idea and as there would be less metal you could use steel, and steel nicely coated with epoxy glue won't rust.
I was forgetting about the angle.

I do like the look of your cannon.

Picked up the bits yesterday Eoin. I also cut the angle at the edge of the deck. It is amazing but even after only 10 minutes work my arms are knackered and I have to rest then for a couple of hours. This Op is going to take a long time to recover from me thinks :evil: :evil:

Now that the deck is finished I have started on the side.
Basic piece is 10mm plywood with a gun port cut to scale (I think). It is secured to the deck at the front by 4 angle brackets bent to 75º to give the rake of the ships side. Secured by screws they will be hidden by the planking that will cover the plywood. I also intend to put a strengthener triangle at each side.

A bit further on now, interior of the hull of the gun deck is now complete. I can only manage about an hour a day at it because of problems with my right arm and a total lack of strength in it. Mind you, taking it slowly = fewer mistakes :loco: :loco:

Not as much bang as I would have expected and not any recoil to speak of.....but you are just shooting a wad and no ball ...right?

Right, 55 grains of ffg and 2 felt wads. I haven't been able to do any casting yet because of my right arm being so unsteady. :evil:

Need twice the powder to get the same report with blanks

Postby NuJudge » Sun Jun 21, 2015 9:58 am

I've visited Fort Mackinac here in Michigan, and watched them fire the canon there. The gunners there use a small charge of powder for the noon gun. They tell visitors that when firing blanks, they would have to use twice as much powder to get the same report as a normal charge of powder and ball. I would guess it would be the same for scaled down guns.

I was surprised you did not include an elevation mechanism.

Nice job.

NuJudge, they used the wedge... Don't think there were any elevating screws on this model gun. They were line of sight and close range. Not much need to correct the elevation. They used mortars for high angle needs.

Exactly right Robert. The screw elevation system on cannon probably started with Field Guns and moved to ship weapons once they became rifled..

On a ship at sea in a gun battle the pitch and yaw of the ship caused by the waves probably had more to do with elevation than any other factor anyway... I'd imagine.

I found this idea on YouTube, posted by a Frenchman and thought it was rather good.

The board is 80cm long, 17.1cm wide and 16mm thick. The guides are 10mm thick and the outer edges 12cm apart.
I am hoping to be able to cast some .69 ball tomorrow and fire some test shots out into the Gironde to see how far they travel................ :roll: :roll: :roll:

The only way to know what kind of recoil you are going to get is to fire the cast ball and see. I'll be interested in reading the results.

A couple of the cannoneers at my club use a similar set up Duncan, they work great.

Looks like you are making progress. 4th of July is Saturday. Maybe fire a salute. ... And yes, I know you have to cast some ammo and you are having some problems getting your right arm to click into gear still.
