Mustafa,

 

I thought your Pickle was an excellent build, but this one is a tour de force!

Thank you Phil. Pickle was a great rest stop for me after Essex.

I made the double eyebolts for the gun tackles out of 0.5 mm brass wire,blackened and installed them to the bulwarks.

I assume you used a 1 mm drill for mounting these double eye bolts into the bulwarks?

Yes Peter, I exactly drilled them with a 1 mm diameter drill bit.

All fife rails are complete. At this stage I decided to make the canopies. While making the canopies I will solder the connection points. I will not be able to make the cube shaped elements in the connection points on the real ship in this scale. The canopy in the photo is a prototype I made to design how to do the job. I will not use it. Now I am working on a jig that will do this job properly.

[Der Alte Rentner]

Ah!  The dreaded canopies..  Looking forward to seeing the final product.  I assume you'll be filing away excess solder and then painting them brass?

Yes Peter, that's the plan.

As we have all learned, there is no easy way to make the canopies due to the fragility of the brass rods to hold their shape and all the required connection points. For me, the hardest point was figuring out how to handle the center hub. If you stack the rods as they cross each other, the structure becomes distorted. If fabricating a center hub where the rods meet at the same level, a jig must be designed so that the multi-joint can be soldered, glued, or mechanically connected in such a way that it is aesthetically appealing as well as strong enough to survive the installation process. This requires patience, tenacity, ingenuity, and it helps if you are a bit eccentric. Builders like xKen (Ken Forman) have the skills to solder and manipulate brass pieces. I came up with a mechanical method which seems to be working for me. It’s a bit out of scale, but it works. It looks like your method will work for you. Looking forward to seeing the finished product.

I admire Xken's metalwork, but there's no way I'll ever reach that level. I didn't try to join the rods together by making a central hub, I concentrated on joining them together by soldering neatly in the centre. Because I couldn't convince myself that I could make such a hub to scale. After a few unsuccessful attempts I found a method that gave me a satisfactory result. As can be seen in the photos I fixed the 0,7 mm diameter rods on a flat surface and soldered them all together in the centre. Here only the diagonal rods are in single piece, the other four are separate pieces. I then bent the rods using a jig and fixed it to a jig to solder the horizontal rods. I find the result satisfactory but the excess solders still need to be filed down.

I completed two of the canopies. 

[Der Alte Rentner]

While zooming in really closely to examine the junctions of the canopies, I took another look at your carronades and noticed the unrigged pair of eyebolts.

I'm happy to see the example and fully intend to follow in your footstep, when I get that far.

If you mean the eyebolts on the gun beds, then yes, I won't be adding tackless to them. Because I added a tackle to a carronade to try it out and I didn't like the look because it looked too crowded. After all, the model is ours, we can do whatever we want.
