I don't think so. I'm sure this boat's gonna be as wet as the original and there's not a lot of room inside for the stuff required to make it work. I also think I'm gonna have my hands full sailing her.

I'll be looking into making at least some guns fire on Macedonian and if I can figure out a repeating system - one of Constellation's pivots.

A couple of weeks with a nasty chest cold and now prepping to move have cut into working on the model, but I did sneak some time into attaching fairleads for the bunts and leechlines on the square tops'l.

There weren't any reef points on the square when I was aboard, but the holes were there.

I'm moving. Moving 10 pounds of stuff into a 2 pound bag actually, and it's been a major pain in the, well, you know which part.

The models are in their new location, and if I can get my shop moved, I can do something to them.

Jib sheeting

This one is going to St Michael's with me to be displayed at the Maritime Museum's model expo. I don't have her ballast mounted on her fin, or a steering system set up as yet, so she'll just sit and look pretty.

On another note: Back in #207 I was looking at an idea for handling the sheets on the over-lapping sails. DanL, somewhere, suggested turning the servo around (I think, it sounds like something Dan would suggest). Well, I finally got to taking that suggestion and preliminary tests look very very promising.

In the attached drawing the sail-arm servo happens to be mounted with a 2.5" arm with two "slave arms" of 4.5" length on either side. When the arm is rotated to it's 90 limit on one side, pushing the slave arm with the sheet attached outward, it nets, in this case, about 5.25" of sheet pulled in, potentially doubled to 10.5"
Mean while, the opposite sheet is completely slack - which is what I'm after.
The sheet relies on the wind to pull it out when the arms are slack/centered, but that shouldn't be an issue.
Multiple mounting holes at the ends of the slave arms will allow more than one sail, with different sheet length requirements, to be controlled from the same arm. Of course, the length and pivot points of all three arms need to be adjusted to get the most from the set-up as well as fitting in the hull. This example would be about 9" wide with both arms spread, well within the 12" in Constellation or the 10" in Pride.
I could even add a non-overlapping sail, like Constellation's spanker, to the servo arm itself.

I'm hoping this will solve the plethora of overlapping sails on Pride and even Constellation, it sure looks like it might.

Tried the system out in Constellation and it appeared to function as hoped. A spring or bungee to return the arms to center would be nice, as the wind isn't always enough to haul out the slack sheet. A cleat mounted on the arms near their pivot points would make adjusting the sheets' length much easier too.

Neat design, well done Dan and Jerry.

You might think about a fairlead to keep the line away from the servo arm's brass post. I could envision slack (due to seas or slatting sails), flipping a line over the brass post.

There's a few refinements to be made. in Pride I'm thinking the whole arrangement may be installed sideways from the above example to make access easier.

Pride went with me to the Port Expo and before we left, I decided she needed to get wet.

This is the first time the model's been in the water since 2012

There's very little ballast in her, so she sitting very high, and the wind's making holding on to her difficult....

Topsail schooners are beautiful, and your Pride is exceptionally so.

Ok, thank's for bumping this back to the top!

I just finished re-reading the entire build log, which I didn't follow before, as its construction started after I wasn't active here. Very gorgeous work here Todd!

I'm especially interested in the hand made blocks (which I might decided to make more of. Also I'm extremely interested in the double armed, servo head sail system that you should.

Is it working as intended? I think I might be able to get that much space in Providence possibly. Something for me to tinker with in the CAD program to test configurations and rigging possibilities!

Thanks again for posting that!

The semaphore-sheeter is working great in Constellation. I may need two of them in Pride with that loose-footed fores'l; three heads'ls and the fores'l may be too much for one servo.

A peek at this neglected model

It's been a useless summer model-wise, haven't gotten much of anything done.

Today, I opened up Pride to do some measuring, hoping to figure out the sheeting setup. A pair of sail-arm servos with "Servo-Stretchers" in-line will handle all the sheets and running stays. One servo for the heads'ls, and the other for the fore and main. The tops'l braces will be attached to the heads'l servo arm.

Sheeting Arms

Let's hope this works....

I cut 4 sticks 6-1/2" long, 3/4" wide, and 3/16" thick from pine.

I tapered and sanded them. They stacked, two each, on a bit of brass tubing as a bushing to keep the pivot holes from wearing larger. A pan-head screw serves as a pivot pin and holds them to a common block so it's all one assembly.

There's a thin styrene "washer" between them and on top, and they sit on a 1/4" Delrin block to lift them over the servo arm.

The block will be screwed to the servo-tray between the two sail-arm servos, one pair facing port, the other starboard.

The servo arms need posts with a bushing to push the arms and all of it has to be able to slip under the shelf in the hatch opening - it's gonna be close.

Tracking shows the new Servo Stretcher should arrive today, so I may have some more to post tonight.
