Hi Paul As I already have the Action sound unit (Whitby lifeboat engine sound, my model) and a 20w amp I sourced some resonators from Holland www.soundimports.eu/. They were out of stock for the initial order so I bought two lower power exciters to see what they were like. Attached to the back deck of my Trent and plenty of volume but the vibration was very visible. I have now received some 24Watt (Dayton Audio DAEX25FHE-4 Framed High Efficiency 25mm Exciter 24W 4 Ohm) similar to yours and they are attached to the hull sides above the waterline and sound great on the bench. Will be trying on our lake as soon as the weather improves but should be as good as the big 8" speaker I was using and several pounds lighter so the model will sit correctly on the waterline. Thanks for sharing this sound medium Mine are attached by 3M VHB (Very High Bond) adhesive so I am hoping if I need to move or replace I can buy some glue to re-attach Dave
The maritime museum's event, scheduled for October instead of May, was cancelled as a hurricane blew up the coast and pushed water up the bay flooding a lot of coastal bay towns like St Michaels. I couldn't make the next Port Expo in 2016, but I tried to be ready for the maritime museum in October. I started making the forward bulwarks. The real ship had sections that folded down on bronze hinges a few of which still exist as she still had her forward bulwarks when she came to Baltimore. They could also be removed. I mad all the section as a single piece and I don't intend to make them functional, just something to snag and need to be repaired. As mentioned, the original winch drums warped and I made new ones with styrene drums instead of wood. These vanished around the time I moved and haven't been found yet, so I got some sheet plastic to take the place of the CDs and made a new pair. I have to say, I'm not happy with these at all. I did add a small block of Delrin to each winch to brace the drums against the pull of the braces/springs. Constellation's board at her entry port were carved. I took a photo of an original at the ship and traced it in PaintShopPro. Scaled it to the model and printed it. I glued this to some bass wood. I have some mahogany I can slice some thing slabs off of, and I may try using a rotary tool to carve a set for real, but till then, these will do. I tried to make the tops'l yard parrels which are iron hoops lined with wood. There's a pin for the yard's yoke to ride on, and the hoop can be opened and hinged to be removed. I wanted all that in case I need to remove a yard at some point without pulling down the whole rig. I tried it with some sheet brass, and again, I wasn't too hgappy with the result. We'll come back to that. So, I fiddled around with cutting combs to make hatch gratings, and actually managed to get something done, which led to making the main hatch cover. I had cut a bit of plywood as a cover, just to keep dust from going below while I was working - I based my hatch cover on this piece, framed the bottom; installed ledged for it to sit on inside the hatch coaming, and made gratings and fake beams on top. It's a bit simplified buy what the ship actually had, but it gets the point across. A couple of smaller gratings also got installed giving the deck a more finished appearance. I wasn't thrilled at bumping the bottom of a pool again, but the maritime museum is on the Miles River. I needed to be able to launch and retrieve the model at a boat-ramp or shore, so I started designing a launch-cart....
Wound the spare trawl onto the drum. Used an old washing bag that you put socks in! The material was soaked in PVA glue and orange poster paint. I have added some rings and sewn some thin thread in green and added some of the warp string too which I have frayed. Sprayed the whole thing in hair spray to hold together!
Wound the new warps onto the winch tonight while watching Glastonbury! Used a mix of green poster paint and PVA glue to stain the string. A lot of warps are wire with this green covering. Will add a little rust paint to some area so they look a little worn.
I began laying the deck on April 5th. It had snowed as recently as the week before, but it finally warmed up enough to use glue. The strips were cut to 6-5/8" length, about 20' in 1:36 scale. I used a black marker on two opposite sides to represent the pitch in the seams. The deck was laid in a 5-plank pattern to mix up the butt-joints as much as I could. My research on her decking found she's had various styles and plank widths over her life. The earliest photo showing her deck that I could find, showed it straight planked with 7 or 8" wide boards based on the number of planks between her waterway and the main hatch coaming. Her waterway logs seem to be placed ON the decking, as there's no margin planks or joggling - even today. The planking was set with gel CA. Gorilla sells it in a nice bottle with a metal pin in the cap to keep the spout open. It would up taking 3 of these bottles to complete the deck. The planks are cut at a 45 on the ends along the fore and aft access hatches, to try and hide this seam as much as possible. Once the deck was down, I scraped it. The glue is more resistant than the basswood is, so sanding would have scalloped the wood between seams. Scraping makes everything level. Some lite sanding, more to polish than remove anything, was done last. I had planned to stain the deck a very light grayish tint, but an active naval vessel gets holy-stoned regularly and wouldn't be gray as the ships that sit at a dock today are. In all it took 455 pieces to complete the deck and there wasn't any scrap longer than 1 inch left over. In all I have 3/4" deck beams, 1/4" plywood, a layer of 4oz cloth and resin, and a 3/16" basswood deck - I don't recall why I designed it so heavy, but it certainly doesn't hurt the model at all, and I think the 3/16" square strip will prove to have been easier to set than the 1/16" x 1/4" planks Pride and Macedonian will get. The deck go a coat of water-based satin poly, and I stared working on hatch coamings, cap log, and waterways. The cabin skylight and two hatched forward of it, including the capstan, and all combined into one hatch where the battery is accessed, and which hides the aft ballast rod and main power switch. The cap logs Are 1/2" wide x 1/4" tall basswood that was tren'led, glued, and copper nailed, onto the deck, flush with the outside of the hull covering this seam completely. The the angled wood waterways were installed around the inside of the cap log, and the deck got a coat of oil-based satin poly. This actually leeched in and made the marker seams bleed a little. In hind sight, I think I'll go with paint over marker for seams in the future. The coamings got painted black. I'm not sure why the Navy painted deck fittings black. It was even common to paint to top surfaces of tops black. I wonder how many injuries and losses this cost the navy that white paint would have prevented. Anyway... Constellation didn't have "solid" bulwarks, but rather she had hammock irons bolted to her cap log. These were removed when Baltimore tried to pass her off as a frigate and tossed in the bilge. When the ship was restored as a sloop of war, they found all but one. These irons are designed to have wooden rails at their tops, inboard and out, and have holes so several lines can be run through them. The Navy in it's wisdom though, decided to wainscot them to appear as solid bulwarks, despite the additional splinter hazard that would be in battle. I wasn't making all those metal stanchions just to hide them under wood and tarps, so I made wood blocks sheathed in sheet bass, scribed to look like vertical wainscotting. It was the end of April by now, and the Baltimore Port Expo was in two weeks. I wanted to have hammocks in the bulwarks, as she appears in the portrait, but there was no time to figure this out, so I layered on some balsa and shaped it so it looked like tarps were laid over the hammocks. When I figure out how I'll represent the stowed hammocks, I can pull the balsa off easily enough. The bulwarks on, I made some fittings for the spencer masts; installed the eye bolts at the base of the masts; made some bollards (or whatever name they gave those posts), made and installed the catheads, which are laminated 1/16" basswood. I then started setting up a jury rig and her controls so she could sail at the Port Expo. I set her t'gallants and all three heads'ls this time around. By the night before the Expo, she was ready to go.
Once I was satisfied I had all the fairleads I needed, or might need (I put in some extras, just-in-case), It was time to permanently close up the deck. The luan plywood sub-deck had long ago been cut into 2" strips to allow it to take the deck camber and sheer. I had also painted on it's underside except where the deck framing was, so the paint wouldn't interfere with the epoxy. I got a few very nice days in October (2014) great for dealing with epoxy, and to take on this major step in the model's construction. There's a sinking feeling about this, like you've just locked your keys in the car. First I removed the mechanical decks below, cleaned out the hull, replaced a deck beam whose joint had never set right, and dabbed epoxy onto things I'd never be able to reach again. The mechanical decks were painted white. The turning blocks for the steering were epoxied in place; having been hot-glued in all these years. Now I painted epoxy on the entire underside of each strip to seal it as well as glue it to the deck beams. Working from out-board toward the center-line. I clamped the strips down, but also used copper tacks to hold it down that would be left in. In short order, the sub-deck was epoxied and nailed in place. Now the only access inside was through the hatches. All the cracks and seams on the deck were filled with polyester putty (Bondo), especially around the deck/hull joint. When this set, I sanded it, filled missed places, and sanded some more. Then a layer of 4oz cloth, left over from glassing her hull 5 years before, was laid on the sub-deck. At this point the deck was an integral part of the hull. I ordered 3/16" x 48" square bass strips to plank the spar deck. I was going to cut this from a maple board I hand, but could get what I wanted safely from the saw. I was concerned bass (lime) wouldn't be hard enough, but it's been great. As holidays and cold weather reduced the time I could spend in the shop, I made up the rest of her spars and their hardware; as well as framing up and installing the fore and aft access hatches. I also cut the deck strips to their length. Then winter came and stayed until April. Meanwhile I hemmed the rest of her sails.
After test fitting the hose ends to establish the correct lengths the hoses were trimmed to size and the fittings were then glued into the hose ends with some epoxy. On the real boat the hoses are arranged to lay on the tops of the foam tanks and they are supported on the stern coaming by a bronze hook. I formed this hook from some brass sheet so that it holds the hoses firmly one above the other, this was primed and finished in gunmetal grey and fixed to the coaming with a couple of brass rivets and a spot of epoxy. For a bit of extra security I cut some large diameter heat shrink to form some bands around the hoses to hold them together. So now the hoses are all finished and I think they look really good, I’ll probably re-polish the brass fittings and apply a light coat of lacquer to keep them nice and shiny at a later stage 😎
The gun deck isn't modeled. I was building a model intended to sail in open water and didn't want to deal with open gun ports, hatches, etc. After glassing the hull, she got beams for the spar deck installed. 3/4" x 3/4", they're probably a bit more than was needed. Tubes were installed for 5/16" stainless threaded rods that would hold her external ballast on. The forward one will be disguised as her galley stovepipe, the aft one is hidden under the cabin skylight. The ballast is a 2" i.d. PVC pipe about 4 feet long, filled with lead bird-shot, and weighing some 42 pounds. With that much done, I took her to the creek to see her float, but I forgot the rods. A few days later I took her out again, remembering the rods, and put her lower masts in her. Now baptized, I applied the moldings and trim on her stern, and built up her enclosed head. Her gunport were molded in resin in the closed position with the guns clamped in the openings and a tampion in the muzzles. These were epoxied into gunports cut from the outer layer of glass and wood battens, leaving the matting in place as a backer. Then she got some paint, mainly because I was getting tired of her looking like a barkless log. The bottom was painted with copper paint, but three rolls of 1/2" wide peel-n-stick tape had just arrived and I started into coppering her bottom right off. Copper plates are nailed on with copper nails with counter-sunk heads through pre-punched holes in the copper sheets. The are FLAT with with a little hollow where they're driven in just beyond flush with the surface. They are NOT round headed nor look like rivets as so many models insist are doing. I pressed an impression of the nails into the face of each plate. Installing them pushes this dent back out and leaves a little circle that looks as it should. It took about a week to do one side, and I took a break to make the tops for the lower masts, then continued onto coppering the other side. It was bright and beautiful when finished, but it wouldn't stay that way. Copper doesn't turn green when submerged, any copper coin will show you it turns brown. I wanted her bottom to brown somewhat, but not too much, and I figured to let that happen naturally. When it got where I wanted it, I'd clear-coat it to lock it in. Two yards of Dupont Supplex cloth was ordered to make her sails. This is the stuff SC&H used on their square-rigger kits and it's great for making sails. Being a nylon, you cut it with a hot-knife, and use a pointed tip in a soldering iron to make grommets. I drew on the panel seams with a .03 marker as even the finest stitching is over scale even at 1:36. Top-cloths, corner reinforces, reef bands, etc, are all cut from the same cloth and glued on with fabric adhesive. The only sewing was of the bolt-ropes. These are done by hand much the way real ones are - I've sewn a few miles of real bolt ropes in my time. There's really no substitute for this if you want a functional scale appearing sail. A machine can't sew it properly, in the right position, or securely.
Here is my version. PM me if you want this and i'll send pictures and pdf with material list and detailed build instructions1/16th scale Fireboat Mast. MATERIALS LIST. Item A:- 1.6 Brass rod 45mm long. Item B:- 5mm dia brass Finial. (from dolls house shop) Item C:- 3mm Brass tube 47mm long. Item D:- 1.6mm x 4mm brass strip 64mm long. Item E:- 2 Off 3mm brass tube 68mm long. Method of build. Start by drilling Item B 1.6mm , then drill bottom 3.1mm x 2mm deep. Solder Items A,B, and C, together to form mast top. Then drill through Item B 90 degrees to mast with 1.2mmm drill for rigging line to pass through. Item D then needs shaping, by tapering on one edge only. 2mm at end to full 4mm x 26mm from end. Do this to both sides. (see sketch). Now drill centre 3.1mm and each end 1.2mm at 3mm from ends. Item E. Flatten one end to 10mm and opposite end to 8mm. Bend 10mm end to 120 degrees. Bend 8mm end to 150 degrees. Now trim 10mm end back to 5mm. Carefully radius 8mm end and then drill 2.2mm at 3mm from end. Now solder 2 x Items E to item D and locate mast top into centre hole and solder in place. The completed mast is held in place by two angle brackets which I slotted through cabin roof and glued with epoxy. These brackets need to be drilled and tapped m2. For the fixing screws 3mm from the top edge, then radius to smarten up.
Started on the upper-works/cabin. Ring saw came into its own again. Followed up by the small mini drill, similar to a Dremil but with a bigger chuck which is handy, using Dremil 1/2" drum sander to clean up the window inner edges. Used 1.5mm ply for the cabin sides as they are going to be veneered, found a pice of veneer under the bench it nearly had roots, and i think, think, it's Teak. This was all glued up under weight using a PVA glue, probably the one in the pics, but an Alphatic. then when glue well and truly dry, Using a No10 scalpel blade to remove the innards of the window frames, and a quick swish with some fine grade sandpaper, not sure about any window frames as yet. ( to many windows for me ... ! ) Regards Muddy....
The next piece I tackled was the bulkhead connector to which the assembled hose is connected. This is not a particularly complex piece but I had to engineer it’s attachment to the bulkhead to allow for easy removal. As with the suction pickup I added four short pieces of brass as turning handles to the ‘cover cap’ for the want of a better description, this cap would be undone to reveal the male connector of the pump intake and the cap would have a retaining chain. This chain would presumably be attached to the bulkhead in some way but I needed it to attach to the base of the fitting. I drilled a hole through the spigot on the cover cap and formed a loop from some brass wire for the chain attachment. Similarly I drilled the base and made another wire loop for the chain attachment there. I didn’t have any suitable chain so I thought I would have a go at making some by winding about 20 turns of brass wire around a piece of thin brass rod which I then cut through lengthwise with a hacksaw to produce some brass loops. These loops were then flattened, linked and closed to form the chain and a short length of the finished chain attached to the fitting. Very fiddly work and a test of the eyesight 🤓 As mentioned, I needed to make the fitting easily removable without using screws or a threaded stud as it needs to be removed without tools to allow the cockpit floor to be lifted out. To achieve this I put a 3mm thread into the rear of the fitting and then threaded a piece of 3mm brass rod to go into that. I made a retainer to go into the bulkhead that would provide a friction fit for the hose connector. This was made from a short length of 3mm I/D brass tube set into another short supporting piece of 4mm I/D tube and a piece of 14 swg brass plate, all the parts were silver soldered together with the 3mm tube protruding the plate by the thickness of the bulkhead. The 3mm tube was cut crossways to form some ‘fingers’ that will grip the 3mm shaft of the fitting. To provide extra grip I used a piece of rubber sleeve and a small pipe clip over the ‘fingers’. This piece was glued into a 4mm hole in the bulkhead with the end of the tube flush with the bulkhead. The hose connecter is then pushed into this retainer with a firm friction grip but is easily removed without any tools. Definitely getting the hang of working with brass now 😁 Still not inclined to by a lathe though 😜 The remaining fittings should be a lot easier...I hope.

Hi Octoman, I usual soak until pliant enough, then bend and clamp over a former, leaving over night same as others have suggested then glue and clamp to prepared formers, I personally have not tried steaming them. I added some pictures of a Funnel I made for my HMS Princess Beatrix model, as you an see it takes quite a curve with out splitting. :-P
