Braces and Sheets on a Winch Drum

lucc,
The braces must be rigged with some way to take up slack that occurs as yards rotate. That prevents any problems with the lines coming out of the drums.
For the headsail sheets, there are no changes in slack as the sails go side-to-side, so this is not a problem on that winch drum.
The time when the lines can come off are when the masts and yards are taken down for transporting the model. When I take down the masts, I attach the braces in a way that keeps them under tension. If the lines hang loose, they can come off the drums.
This winter, I will take time to write more in the "details" thread.

A good way to glue a winch drum assembly

lucc - here's an addition to attaching the CD discs when making the drum. In addition to three fine screws or pins as shown, I also use CA glue with baking soda as a filler/hardener.
I lay in some CA, then sprinkle baking soda over the wet CA. It sets up almost immediately. Add additional layers to build up a strong bond.

Winter doldrums...

Haven't posted any Syren stuff for quite a while. Found a whole file of old pics - a lot of closeups. Thought I'd post them for winter entertainment for those of us nearer the north pole...
Probably some repeats, but I think many are new posts...
Same pics in a slideshow (not very good quality)

I love to look at photos of your magnificent ship. You have far more detail that shows up in the photos than when we are sailing because we are trying to concentrate on something other than the details. These are absolutely great.

Once again, DanL, several of your closeups just look too real to be a model. Your hand-laid rope is beautiful. Well Done.

i totally agree and very much appreciate you posting every picture you have of Syren
The into the rigging shots are incredible, one is hard pressed to tell they are not from a real ship!!

And Dan, i`m right now in Qatar, perfect temps, outstanding sailing wind and a clear blue sea... but you know what the torture is ? The models are 3000NM from here

DanL, the only reason I am posting this reply to this thread is to keep it from disappearing from this Scale Sailboat threadlist, which it seems about to do. The excellent photos and information included is just too great to lose to thread heaven. Not to mention the excellent model on which this thread is based!

Oyster - thank you very much.
Has been a busy year witha major move, etc etc, so not much new in the way of pics or sailing experience. But I really hope to sail Syren a lot this coming summer...

Firing Gun System - Multi Shot

Firing Gun System #1:
Here's a drawing of the system design so far. The concept and major components have been tested and all looks feasible.
More details as construction proceeds...

System consists of a delrin block machined with 5 barrels, lined with brass. Calling this the cartridge block. The other key component is the gun frame.

The cartridge block slides through the gun frame - one gunframe at each gunport.
So, stbd and port each have 9 guns with 5 shots each.

Ignition is with a thin nichrome wire that is replaced with each cartridge block reload. Replaceable approach is taken because having thick enough wire to be a permanent igniter slows the heating response and is not as reliable as a thin wire that "evaporates" when the current hits it. Also prevents situation of a failure mode where the heater wire stays "on" and something fries due to the high amp flow.

The blocks are advanced in the gunframes by a servo that moves all the blocks in unison. The blocks are linked to each other by adjustable threaded rods. Each barrel in the cartridge block, is, in turn, advanced into alignment with a "stub barrel" in its' respective gunframe. More on the advancing system later.
Actual firing of a rolling broadside is still controlled by a rotary switch.

More in post #2 as work advances.

Note - now there will be 90 BP loads onboard (vs 18 in the single shot gun system). I realize the potential risks. Don't try this at home....
