WOW!!!
I never would have guessed that those barrels are plastic ! Amazing !
Adi, Mirek, Grant, Gunter, Allan, Herman, Daniel, Jan, and Jeff - and to all the likes - my thanks for your encouragement and kind words.
And now mounted on the ship:
That was quite a project with lots of small custom bits and baubles... I'm happy to see it in my wake (I must have been thinking about these guns for a few months before I finally built up the courage to attempt them).
And, as always, thanks for stopping by to see what I'm up to!

They are looking great, Paul. And mounted on very nice stands.
Regards, Peter

Nice!Hello Friends,
Work this week focused on creating eight swivel guns.
Gun barrels were provided in the kit, but time has not been good to any plastic components so they could not be used. Knowing that, I previously purchased turned brass barrels as replacements, but when it came time to use them I realized they were too small. When I went back to that same after-market supplier I was sad to discover they no longer sold brass guns - only injection molded guns. Nuts.
I much prefer to use metal for those things on the ship that were metal, but I just couldn't find what I was looking for, so I ended up using the injection-molded versions. I did my best to hide the fact they were plastic. Yes, I know you all would have just had some custom barrels printed, but you weren't here to talk me into that. I'm already unhappy, so don't beat a man when he's down...
Swivel guns have a control arm (a tiller) so the first thing I did was shape those with a mini-lathe and file:

View attachment 503602
Next, the gun is supported by a pivot mount (which includes a vertical post and a yoke). It took me a few days to imagineer how to fabricate the yoke. My final solution was to cut a sheet of brass stock into an appropriate pattern and then shape that into something usable:

View attachment 503605
View attachment 503606
I then soldered the vertical post to the yoke:

And bent it into shape:

I blackened the metal components and did my best to turn a plastic gun barrel into an iron gun barrel:
View attachment 503610
View attachment 503609
To be continued...

...painted and treated with graphite powder.
You obviously have never seen my Vasa build

Funny thing is that I HAVE seen your Vasa buildYou obviously have never seen my Vasa build
and so has most of the rest of the world!
Good morning Paul. Brilliant guns. Those open gun ports, look very interesting in the photos with the look through into the hull. Are you leaving these like this? Cheers Grant
Paul,
Beautifully executed. Thank you for giving us some insight into your imagineering. It is that talent to which we all aspire.
Great imagination and engineering.

You mentioned that the guns were injection molded. Making even a single cavity injection mold is a huge expense as is the equipment that houses the molds, when compared to 3D printing or casting molds. I had no idea there were after market suppliers with injection molded barrels and would love to find one in the US to compare to 3D printed barrels and my own home made resin cast barrels.
I am also curious about the use of the graphite powder. 3D printed barrels can show flow marks, especially at large scales. Matte finish paint definitely helps, but I wonder if the graphite powder would help even more. Have you or any of your build log followers used this on 3D printed parts?
Thanks in advance!
Allan
Thank you, Peter. All inspired by your micro-work!
Thanks, Johan. No museums though my kids are already talking about how they will get rid of the Vasa when I am dead (can it just go in the garbage can?).
Thank you kindly, Peter!
Thank you, my friend. Likewise, your lion!
Thanks for the nice review.
It turns out that there were only a few gun port lids on this ship (only at the extreme fore and aft with the remainder being open all the time). If you look to the interior build-out it is only at the extreme fore and aft that the guns are in closed spaces (rooms with doors) - all the others are open to the air (though several are under a portion of either the quarter deck or the fore deck). Those port lids and hinges are up next when I get off the computer...
Thanks! That little project took three times longer than necessary while my brain warmed up to what I needed to do...
Ha! Dentistry is the thing I am good atVery impressive micro fabrication Paul! Have you considered a career in the dental field?
. Of course, there are some transfers that make my hobby time fun.
Hi Allen,
From your post I would have to say I am mistaken about them being injection molded (I didn't know that referred to a specific manufacturing process). I was using the term generically to mean they were not turned on a lathe nor were they printed. Perhaps they were resin cast. There is a horizontal bar with a series of sprues that each lead to a gun barrel - is that resin casting? They definitely came out of a two-piece mold because I can see the mold lines.
And no, I have never used graphite powder on a printed part. Indeed, I have never held a printed part in my hand
. Let's see if anyone offers up their experience... But I will tell you that the powder is a mere wisp of a thing - it wouldn't hide any surface irregularities...The swivel guns were from Chuck. I am sad he no longer sells brass guns.
