Thank you, gentlemen! I didn't know there were rules here. Cool, thanks! :) Will fix

[Olli Sukunimisson]

Well, the construction has changed, but I still love the wheels. They're so round! And they balance the cannon!

I'll paint them black.  

 

[Waldemar]

 

Well, let's have that consensus . Thanks for the pleasantly correct general appearance already .

Judging visually, the original parts from the kit have quite the correct proportions. The usual culprit in such situations is an undrilled bore in the barrel, which shifts the centre of gravity forward a lot. So either you can drill that hole, or fix the gun to the deck with glue, mechanically or both (or some other similar way that will take care of the problem).

 

The hole in the barrel is just a few mm deep, as drilling them deeper caused production difficulties (and a lot higher production price).

I just glued them in position with a drop of pva glue underneath it.

Oh my... Sorry Olli, but as a lover of old artillery my heart is heavily bleeding... Please bring back the original design of the carriage. That is, the barrel's trunnions just above the front axle, the barrel's base ring above the rear axle (should fall on it preferably in an arc, not vertically), and the trucks of wood only (no metal on the perimeter).

 

 

You might find this interesting: we have started some time ago with the development of a kit of a 17th century bronze canon. This should come to live somewhere this year.

 

 

@ Olli, sorry for interrupting your log.

An extremely attractive cannon barrel indeed, Hans (and the carriage, too). Is it resin or metal cast? Or 3D print? What's the scale/dimensions? From the authentic looking details I estimate it to be based on a real specimen. All in all, fantastic effect. Congratulations .

It is resin (credits to my son who designed it after an original 17th century canon), 3D printed on a resin printer. 
I coated it with real bronze powder, soluted in schellack, and gave it a ammonia treatment to give it the authentic weathered look.

We can print in in almost any scale, but the maximum length is roughly 20 cm. 
 

The carriage is made out of oak, but for the kit this will be most likely elm (which was the most used wood for carriages, according to Blom).

 

I am still “struggling” with the size of the weels, as they might be a bit to large.

@ Olli, sorry for interrupting your log. 

Cool. Something completely different.  Now I have a reference I can use for inspiration.

I can only reiterate that the effect you achieved is already sensational. However, if you'll allow me to hint at something, I'd say that, in practice, for the diameters of the trucks, there weren't any ‘standards’ that had to be strictly adhered to; these diameters were simply selected so that the barrel fell in the middle of the gunport. But already the diameter of the axletree arm (spindle) was typically equal to the calibre of the gun, as was the thickness of the trucks.

I realise you may already know this, but perhaps such general guidelines may be useful to others.

Below is a reproduction from a Swedish work on artillery from around 1700 (D. Grundell, Nödige underrättelse om Artilleriet till Lands och Siös..., Stockholm 1705, Plate X), where in the the lower right corner it is demonstrated how to select the diameter of the (front) truck to get the correct barrel height.

I’ve got two barrels now, one plain first try, and the second one with all the decoration and modifications in the size. 

This is okay:

 

size of the spindle and diameter of the inner barrel

No, no, no... I have meant the diameter of the wooden axletree arm/spindle (of the carriage), and not the the diameter of the barrel's trunnions. The latter is indeed okay in your gun, as you have just shown.

Hi Hans,

Not only according to Blom, also Van IJk mentions elm as the better material. Compared to the drawing in Van IJk and compared to the ‘Hollaendische Zweidecker’ as photographed by Winter, your wheels  are indeed ‘oversized’

The model is deceptively ‘real’, its your furniture that gives it away

Well... it's closer to the reference. But I'll keep my fancy wheels—I'll set them for Koningsdag and De intocht.

But the cannons, along with their gun carriages, will tip forward. How do we deal with this?

Secure the carriages with a screw... A bit over designed, but effective 😇 

[Olli Sukunimisson]

Hm... I love this solution! Sure, I'll think about something like this. Thanks, Patrick!

[Olli Sukunimisson]

Well, the fittings are more or less done. I'll set up the cannons next, and then comes the scariest stage—masts and rigging!

[Baker]

Very nice 👍
