Roger Pellett got a reaction from FriedClams in USRC Ranger 1819 by Cathead – FINISHED – Corel – Scale 1:64
Hi Carhead,
Two pictures added, hopefully better than the last. It looks like someday, I need to take the model out of the case to dust, but not today.
I don't think that there is any way to build this kit to accurately represent actual practice without major surgery. Assuming that the bottom of your transom now sits on the horn timber, you need to erect angular knees on top of it. These knees will be at an oblique angle equaling the sum of the rise of the sheer line and the slope of th transom. The lower part of these knees should be cross planked and the transom will be fixed to the upper. Since this vessel has no bulwarks, the transom will appear perched up somewhat as shown in the Lousiana picture above.

Roger Pellett got a reaction from Larry Cowden in USRC Ranger 1819 by Cathead – FINISHED – Corel – Scale 1:64
Hi Cathead,
Sorry, taking pictures through a glass case is difficult. Tomorrow AM I'll try to get a better picture outdoors.
Furthermore, my description was incorrect. The hull planking does twist up to the top of the horn timber but the transom does not sit directly on top of the horn timber. Instead, there is a series of transom knees that mortise into the top of the timber. The lower part (the more horizontal section) of the knees is cross planked and the rudder head passes through this area. The transom is fastened to the upper section of these knees. The profile of the Louisiana that you posted above shows this arrangement.
This arrangement accomplishes two things. First the structure protects the rudder head. Second, it moves the main sheet aft of the rudder head. As you will recall from building your longboat, otherwise, the sheet interferes with the tiller

Cathead, perhaps this might help. Planking on this type of vessel usually ran up to a horizontal cross seam at the top of the horn timber. not to the transom itself as you show. This required a major twist. Possibly, the manufacturers of the kit sought to eliminate this to simplify construction. The transom sat on top of this, the seam covered by a moulding.
The attached photo shows this same construction in my model of the pilot boat Anna Maria.

Roger Pellett reacted to bluenose2 in Contact cement for hull plating
Hello Roger, Les here. Solvent based contact is a good choice. Pre prime areas to be covered with a gloss coat of anything you like. That way the contact has a good bonding surface. Coat both sides with a thin covering of contact. Wait till dry to the touch then apply. Be aware however that grab will be instantaneous, with no way to reposition. When doing compound curves, pre form the piece before bonding otherwise you may get a crease when trying to laminate it. This applies to coverings that aren't backed with an adhesive.

Roger Pellett reacted to pete48 in Eel by pete48 - FINISHED - 3/4" =1' - SMALL - William Garden Designed Canoe Yawl
Finally the Roller furler was made along with the Jib, Bowsprit finalized , Standing rigging finished Solar panel made and installed along with Vhf antenna and Air cowl in the bow. In conclusion she took about 5 months to build, the Client was thrilled and said it looked even better when he saw it in person, She was a lot of fun to build

Roger Pellett got a reaction from thibaultron in Contact cement for hull plating
Thanks, Jaager,
I have a roll of .005 in copper approx 1/2 in at scale. Not too over scale for hull plating. Much softer than brass so maybe it might work better than the harder brass, which I hadn't annealed. Maybe this might work with the transfer tape.

Roger Pellett got a reaction from thibaultron in Contact cement for hull plating
For more years than I care to remember I have been building a model of the Great Lakes Steamship Benjamin Noble. A couple of years ago, I started to plate the hull with brass sheet stock using 3M transfer tape. This tape is adhesive deposited on a waxed paper backing. The tape is applied to the brass plate, the paper is peeled off and the plate is now coated with adhesive. Plates are approximately 1in by 3in. After laying down one strake of plating, I let the hull sit for a week or so and found that the tape had failed to hold the corners of the plates. The model has been sitting while I work on another project.
I am now to the point to try again, this time using copper sheet secured with contact cement but the brands of cement that I have found all say don't use with copper or copper bearing alloys. Considering the number of copper sheathed hulls that have been made, someone must have discovered a contact cement that is compatible with copper.
Any advice?

Roger Pellett got a reaction from -Dallen in How to deal with badly drawn plans?
The view that you shown includes water lines drawn parallel to the keel, station lines perpendicular to the keel and buttocks. Assuming that you have at least one more view (a plan view or a body plan) you have sufficient information to reconstruct a lines plan.
Start by preparing a table of offsets- x,y,z coordinates measured from the centerline for water lines and base lines for buttocks. Then plot them and pass curves through them. Whether by hand as I prefer to do or by CAD the process is the same. Your body plan (frame shapes) may be plotted from your other two views. Your curves may not pass exactly through all points and here is where some judgement on your part is required to produce "fair" curves with intersections that match exactly in all views.
Keep in mind that a definitive lines drawing that exactly portrays the shape of a known vessel is an illusion. Five naval architects making five lines drawings from the same table of offsets will produce five slightly different drawings because of the fairing process described above. The important thing is to make a drawing that accurately portrays the vessel's characteristics.

Roger Pellett got a reaction from Old Collingwood in HMS Argonaut (F56) by crabbersnipe - 1/96th - Leander-class frigate
My experience is that sharp corners and fiberglass don't get along well. The glass fiber wants to float on the resin precluding sharp corners. It might be easier to cast the sonar dome in place once you have glassed the hull.

Roger Pellett reacted to EdT in Albertic by michael mott - FINISHED - Scale 1:100 - RESTORATION - Bassett-Lowke Model
Micheal. maybe you've tried this but if not, why not mask with tape on either side of the brass flanges, apply liquid masking to the flange, allow to dry, slice the mask along the edge of the tape with a sharp knife to avoid jagged edge, remove the masking tape, paint the funnel, peel off the liquid mask?

Roger Pellett got a reaction from mtaylor in Jarvis Brace Winch
Daniel,
I don't know whether your query is to support construction of a model or for some different purpose, but another source that discusses brace winches and rhe ships that carried them is Allan Villers' The Way of a Ship. There is a good isometric sketch of a brace winch in this book by Harold Underhill. Villers' perspective is that of a practical sailor who actually used this gear.

Roger Pellett got a reaction from Mirabell61 in Jarvis Brace Winch
John Harland's book Capstans and Windlasses available used from Amazon for $9.98 includes a chapter on brace winches and the Jarvis winch in particular. Illustrations are not great, not as good as Nils posted above, but there is useful written descriptive material that would appear to be the kind of stuff that you're looking for.

It is thought that access was via the lapstrake planking of the great arch behind the forecastle. Some reconstructions show a ladder into the forecastle but I elected not to put one in because of space restrictions. I could be wrong. I am sure that there would have been a lot of variation.
Mariners of those time did not have unions or occupational health and safety officers. They took a lot of risks we would find terrifying e.g. reefing a sail without footropes.
