Henry Grace a Dieu (Great Harry) by Louie da fly - Scale 1:200 - Repaired after over 40 yrs of neglect

Very nice, Backer, and explains the whole thing very well.

 

At first I thought the gonnar didn't have the nerve to stand to his gonne while firing, but the second run of shots using a slow match proved me wrong.

 

A very impressive display. I'd read that these breech loaders were rather inefficient because it was impossible to get a good seal between the cartridge and the barrel, so a lot of the explosive gases escaped instead of propelling the ball.  But maybe not, looking at this video. I certainly wouldn't want to be on the wrong end of something like that.

 

It seems to me though, that the gun wasn't built up from wrought iron staves, unless the finish is a lot better than would normally be expected. Maybe because of safety rules?

Here's the sequence I used in making the built-up cannons. Using a bit of 1.5mm brass tube set into my "poor man's lathe" - its main disadvantages are that you have to keep a finger on the start button (yes, I could bypass this but didn't bother) and that there's no support on the other end so bending of the tube is a risk. I overcame the second by sawing right up next to the jaws of the chuck, with just the combined thickness of the sawblade plus the reinforcing ring sticking out. Not so good either for the sawblade or the chuck, but I managed to get away with it. Then slide the tube out of the chuck by the same combined thickness of sawblade and reinforcing strip and do it again:

(I forgot to photograph the first cut, so the above is of the second.) Then the same thing again:


 

And again:

And then the "magazine", using a file:

20191209_213108.thumb.jpg.9f5858ee333c09e8bc7430e778c29109.jpg

And cutting the whole assembly to length

And here are the completed barrels. The upper group are the first ones I did.

20191210_102816.thumb.jpg.57c67f60bdb859065efb432acf522828.jpg

I later discovered I'd got my arithmetic wrong and they should have been longer, as are the ones below. I also didn't add magazines to them, but as only the ends of the barrels will be visible i decided just to forge ahead - any major differences will be hidden within the hull.

20191210_102802.thumb.jpg.bf5b8807c25d3b8627f2f9690a00d652.jpg

Note - I inadvertently cut the magazine off one of these, but I figure I can just put it on the carriage behind the barrel and it should be fine.

 

And I've cleaned up the "cast bronze" barrel I made back when I was 17, and I'll be casting a group of them which will be visible in the waist.

 

Plus one I turned on the electric drill for the gunports where only the end of the barrel will be visible. I think it's close enough to pass muster . . .

Here is the first attempt at a built-up gun and carriage, based on one found on the Mary Rose in the 19th century:

 Barrel and carriage (carved from pear wood):

20191216_125529.thumb.jpg.1ab5e85c6e8624e2e914486b0f4c221a.jpg 20191216_125558.thumb.jpg.a23f57bebf83cf5d51b971e9c048bf5d.jpg

Wheels:

 

20191218_134525.thumb.jpg.f26d13b157b1427795845500dd42ad02.jpg

Wheels on axle, plus elevation mechanism (a vertical wooden beam at the back of the carriage with holes to put a pin into to adjust the elevation). 20191218_134500.thumb.jpg.29a3a4792a259f9f799fbe9f6a121e3e.jpg

Carriage assembled - note as this is a preliminary version I haven't cut the axle to length.20191218_135226.thumb.jpg.4edd2f32177d2a2787770e2b037ed8a9.jpg

20191218_135253.thumb.jpg.614d95d381d65bd31e9e054e21455f2d.jpg

Barrel in place, (with magazine included as part of the barrel), and elevation mechanism cut to length. Axle cut shorter, but will have to be removed and cut to its proper length.

 

It became obvious that I'd put the wheels too far back - the elevation mechanism depends on the weight of the gun resting backwards, so the wheels should be a little forrard of the centre of gravity - and of course otherwise the thing tips forward, as it does here.

20191218_181754.thumb.jpg.b6bd9b13e6504db1b8014d222e2c799b.jpg 20191218_181800.thumb.jpg.dbbfbd18a496ac5d4c2be98b75c19c14.jpg

20191218_181853.thumb.jpg.87148318d9c000f36d06b070b7cb3e5b.jpg 20191218_181857.thumb.jpg.2368d937f5a6e6c7090ced4b9f1147f6.jpg

As I've glued the wheels and axle on with CA I'll need to dissolve it - am I right in thinking nail polish remover works for this?

 

And here is the "blank" for making the rest of the carriages. The holes will be cut in half to make the "beds" for the gun barrels.

20191218_182138.thumb.jpg.c93056f87c6018f427be41e5fef6108b.jpg

This is really only for my own satisfaction - the carriages will all be pretty much hidden within the hull - but it's fun doing it. The guy across the road (he drilled the holes with his mighty drill press) thinks I'm nuts.

Nice work Steven, pity you have to remove some parts.  Nail polish remover is just acetone which you can get at Bunnings fairly cheaply (may save you some grief  'borrowing' it from your regular supplier ;)  Not sure if IsoPropyl would be better but I think the latter is for PVA/Yellow glue not superglue/CA softening/removal.

 

cheers

What Pat said... just make sure the nail polish remover is acetone.   They are making many that don' t have it.   IsoPropyl won't dissolve CA.

Thanks Mark and Pat. I'll make sure I get the right kind. I don't think I want the amount of acetone you can get in Bunnings, so it looks like I'll be perusing the health and beauty aisle at Coles . . .

If not too late Steven, you can buy small amounts at Bunnings,  I have a 1 litre can but I think you can get even smaller.

Mass production of built-up cannons.

 

Gun barrels threaded onto a wire and painted black

20191224_141601.thumb.jpg.099a895542419a1f64104fe7aed8c7d4.jpg 20191224_141609.thumb.jpg.7d0227c4ea12b52c91ab31d3e6f5ab0d.jpg

The blanks for the carriages cut apart

20191223_085021.thumb.jpg.c2554cf4f26a4134bda7c1184ca87011.jpg And trimmed down to make half-round "beds" for the barrels.20191223_100732.thumb.jpg.57a85544546ede31b77c2d40099cb515.jpg

And separated into individual carriages

20191223_101237.thumb.jpg.7e4f39244f49483f013546bb915001e6.jpg

The third carriage under construction - As they won't be seen anyway, making full carriages was just to satisfy myself that I could do it.

20191223_103046.thumb.jpg.e109ccd85ef707765d0cc306a8660ceb.jpg 20191223_112239.thumb.jpg.1615e7ab3e8f46933019131f2a398cac.jpg 20191223_113903.thumb.jpg.44fb5bf4bb7d6417039ffe8cc26b3478.jpg 20200104_163529.thumb.jpg.4bf8e78521b24e08613d7ab757007cf0.jpg

So for the rest of them I just made blocks to take the place of full carriages.

 

20200104_202427.thumb.jpg.569c72466483df9baf11d0d5cee75c02.jpg 

 

More to come.

I've had to make some adjustments to the ship to allow the guns to be added. For a start, the forecastle doesn't have any internal decks for the guns to sit on, so I had to think of some mans of supporting the gun barrels without having to take off the top deck. It occurred to me that I could put timbers through the relevant gunports and cut them off flush with the inside of the sides of the forecastle and just manoeuvre them so their top face was level with the bottom of the gunport, and that would form a support for the barrels. Here is the forecastle with the beam sticking out of the gunports either side, prior to being trimmed.

 
 20191224_141339.thumb.jpg.9683186a33d3f60c9df52b10c8dd4960.jpg 20191224_141436.thumb.jpg.1c59f71a750e019b82cfc52a6fbec746.jpg 20191224_141330.thumb.jpg.3f6eeed50028fbcf42ae006e09a0488a.jpg

The timbers in the forrard gunports haven't yet been trimmed, while those of the aftmost gunports have - you wouldn't be able to see anything until the guns are inserted.

 

And here are the sternchasers:

20200104_204026.thumb.jpg.8006fc7ad2c93e8ec504313c233ac316.jpg 20200104_204029.thumb.jpg.83d9bedfb18c6c1d445fe0cf0fed66c0.jpg

As you can see, with the built-up cannons the barrel hardly sticks out past the front of the carriage at all, so it is only barely visible sticking out of the gunport, which perhaps explains the way they sometimes appear in contemporary pictures.

Good solution, a significant improvement of the model compared with what you started with.

Not too much, I hope. I'm continually torn between repairing it to be the same as it was when I built it, and putting in improvements in line with what I know now. 

 

The underwater hull shape was based on Mathew Baker's late Tudor drawings while the gunport configuration is based upon the illustrations in the Anthony roll, both of which the Mary Rose discoveries have since shown to be inaccurate. The colour scheme is also based on Mathew Baker, but contemporary pictures of ships show a much simpler colour scheme for the time of the Great Harry.

 

However, I'm afraid I'm not terribly consistent with this. I'm re-using all the existing superstructure as-is despite knowing the colours, upper structure and number of gunports aren't correct. But I've changed the shape of the underwater hull and I've made these cannons in line with the Mary Rose discoveries (not available when I was 17). The model as it stood had only one cannon.  I was planning to cast a whole lot more of them but never got around to it, so I feel (somewhat) justified in adding new, more accurate ones.

 

And the (lost - to my very great regret; I was and am very proud of what I was able to do at the tender age of 17) longboat will be double-ended instead of having  a transom stern as in the original, as this seems to have been the way they were at the time.

 

At least as far as the hull is concerned it will be possible to see the old vs new work because the colour of the wood is different. However, I'll be making the upper deck of bamboo as I did at the time, even though I could do it far more accurately now.

 

So, it's not really Arthur or Martha - neither a pure repair nor a "renovation". Still, I'm not too concerned - it's my model after all, and I get to decide what I want to do with it.

I've been working on the hatch cover. At 1:200 I don't feel capable of making the gratings using halving joints - my work is nowhere near that precise at the best of times. So I've made the grating the way I did on the original model, with one layer of thin  laths of bamboo in one direction, overlaid with another layer at right angles. Not perfect, but unless you really look hard it looks like the real thing.
