JSGerson got a reaction from Unegawahya in USS Constitution by JSGerson - Model Shipways Kit No. MS2040
The trick here is cutting the brass slots to accept 0.020” Ø brass rod. My fine-tooth miter hand saw is 1/128” (0.008”) thick, cutting very narrow slots. The slots were 1/64” too narrow and my files were too thick to fit in the cut slots to widen them. Using various drill bits in my variable speed Dremel at the slowest setting, the slots were widened by sliding the spinning drill bit up and down the slot cutting with the bit’s side. Sorry, I could take a picture of this, as I needed both hands to perform this procedure.

Fifth Attempt
Ok, let’s be more pragmatic and increase the diameter of the hub to 1/8”Ø and sacrifice a bit of scale. If I’m going to do that, I can also discard the styrene for the hub material and come full circle and use brass tube once again. Since I won’t be drilling holes, (the reason for the plastic in the first place), but cutting slots, I’ve eliminated the brass holes problem.

Fourth Attempt
The next development was the idea to make a double support such that the brass rod would pass into the hub and back out through a difference opening as a second support. This would mechanically fasten the brass rod to the hub. To do this, I would have to change the drilled holes in the hub to vertical slots so the brass rod could be dropped into the openings. It’s not like the rod can act like a piece of string that can be threaded.
This introduced a new problem. Once the holes in the styrene hub were converted to vertical slots, the remaining vertical styrene material was now narrow, flexible, and weak and would break off should anything tug on them…like the brass canopy rods. Additionally, more room is needed to accommodate the bends.

Third Attempt
My next idea would be to cut the 1/16” Ø brass tube leaving the 1/32” Ø rod alone uncut. Now there would be two 1/16” Ø brass tubes one on top of the other with a gap in between, wide enough to accept the 0.20” brass rods. This expose tube wall would extend the rail seat another 1/64”. Mechanically, it is slightly stronger than the previous idea, but still fragile. And how does one assemble 7 to 8 spokes into the hub and hold them in place precisely to glue them together with sufficient strength?

Second Attempt
I was forced to make a small dimensional compromise. The top part of the full-scale ornament is 2” in diameter which scales down to 0.03” (1/32”). This had to be enlarged to 1/16”Ø due to fabrication practicality.
At the center of the hub, is the ornament which consists of a 1/32” brass rod which is inserted through a 1/16” brass tube. At the bottom of the tube, the 1/32” rod extends out into the 1/16” brass bead. At the opposite end, the rod and tube were to be filed into a rounded point.
However, the enlargement forced me to remake the styrene hub component. The 3/32” Ø styrene tube’s inner diameter was about 1/64” was too narrow to allow the 1/16” Ø brass tube to pass through. It had to be drilled out with a 1/16” drill bit. This left a very shallow 1/64” tube wall rail seat for the 0.020” brass rod to rest on and glueing surface. Mechanically, this would be very fragile and would not secure the 0.020” brass rods.

First Attempt – Original Plan
As mentioned in my earlier posts, I had to forgo using a brass hub because I had difficulty drilling holes in brass and thus substituted styrene. The styrene hub 8 circumferential support positions, of which 7 of them for this canopy support, were drilled with a hole to accept an arched support. Unfortunately, drilling these holes practically cut the styrene tube in half.

To fabricate the arched framework, I had to work out how to make the central ornament. If I had a metal lathe (and knew how to use it) it might have been relatively simple...I think, maybe. But I don’t, so this is how, why, and what I worked out, based on the US Navy plans.

Attaching the “spider” to the stanchions went smoother than I had expected. The legs of the “spider” were trimmed and be approximately even with each other. Then a brass bead was added to each support and inserted into a stanchion, moving around the hatchway one by one in turn. The last support (unpaired) was cut to size from the “0.020” brass rod and added to complete the canopy. It’s not perfect, a little out of scale, and maybe a tad crooked, but it’s done. This one assembly took almost two months to complete. Now that I know what to do, hopefully the remaining four frames will go a little easier and quicker…maybe.

I might even be worse for the MS kit! That's why we have forums, to share ideas and learn from each other.

Unegawahya: I am making slow progress on my first canopy, working out the process (I've had a lot of false starts). My current method, so far, has worked out to be way more complicated than yours. I will post details and pictures once the fabrication and installation is done because I still don't know if what I have done up to now will be the final method.

Peter, that's a thought (now Plan D), but I would like to include the frames if I could.
It wasn't so much as to "keeping lines randomly scattered around the deck to show the ship in a state of action" but to show a working ship. There is a lot of stuff on the busy decks so they are not as neat and clean as many other models show. My ropes lines are loosely coiled because they are theoretically in use, not set up for formal inspection. Presently, I don't plan on adding sails (it's taking long enough as it is), so presumably this is what the ship would look like in dock for a while, in which case the canopy frames would be set up. But then again, they didn't exist during the ship's active fighting years. I'm working this out one step at a time.
I'm still trying to figure out how to attach the multitude of arched brass rods together at the hub. I've been doing a lot of thought experiments as how to precisely hold in place 7 to 8 rods, plus a ringed ornament securely enough at the same time and with sufficient surface area to apply glue such that the assembly won't fall apart as soon as I try to move or install them into their positions on the stanchions.
Mustafa, at the rate that I am moving, I suspect you will be working on these very soon. It should be very interesting if you method solves my problems.
