    Hi Martin, thanks for catching up, and for your nice words to the harbor tour pics... I`m glad you liked them Nils

    Hello Doris, I was missing your posts over the last months and hope you may find time again to share your brilliant work with your MSW fellow members. I am with Druxey and Michael with my compliments and gladly look forward to your progress with this new project. Es ist wunderbar ! Nils

    Thank you very much Piet, I`m pleased you liked the engine room pics (bringing back steamship operating memories). I was myself surprised that the engine room crew had no objections in letting me down into the engine room, also through a tunnel in the coal bunker, and right before the boiler furnaces.... With the "closed" boats reproduction I`m quite pleased with the result so far. I`ll give it a try for the open boats as well, perhaps it may take several trials, in order to find out the critical points of the procedure, Thanks for your input on the possible help for peventing tearout on those "canvas cover" details Nils

    Carl, many thanks for your appreciative words,... the first casts unfortunately show some places where air bubbles had been trapped especialy in the fender rope region, but that could be solved with applying a little more seperation wax there. In all I`m also very pleased with the detail reproduction, I thought it would be more complicated... Nils

    Thank you Greg, for your nice words and that compliment... there is really a mass production of boat halves going on right now, the first boat (halves) are glued together.... Nils first boat "cloned" (next to the master boat)

    Wow B.E. what a lovely display, and that beautiful casing. Love that little side table she is standing on. Congratulations to your wonderful rounding up of the project, an awsome looking piece of maritime art... Nils

    Update : further with boats production....... It is my first attempt to make parts in silicone molds and to cast them out in polyurethan resin. I`m quite satisfied with the result so far, and pleased that it worked out so easy.... Here a little documentation to share of the procedure (to whom it may concern) Nils making the boxes for the silicon molds, comprising baseplate and side walls positioning the master model (halfside by halfside) into the box frame, holding it in place with a simple but adjustable support device checking the horizontal centerline position.... two component silicone mixing relation 1:1, for the mold seperating wax for the mold the first mold half in silicon, the master inserted slightly more (0,5 mm) than half deep removal of the master half..., the lapstrake structure and even the fender-rope mold out well and precise two components othe polyurethan resin and its catyliser (mix 1:1) casting three halves at a time. The activated polyurethan resin has a working time of appr 2-3 minutes after mixing the two components together, before it starts to polmerisate and to turn to white coler as it does so the result of the first attemt to cast the boat halves, now ready for fairing, trimming. The activated resin batches (every batch at a time) is measured for 5-6 boat halves

    Many thanks Greg and Igor, for your kind comments.... Greg, yes, I was very pleased especialy to stand next to the men in the boiler room shoveling coal into the furnaces, and also to watch the engine crew obeying the machine telegraph, reversing the engine (mighty "Stephenson reverse device") at work Igor, am pleased you liked the Photos...... I tried in vain to add some videos, but they were much too big for posting (appr. 30 - 60 MB) Nils

    Part 2 most of the ships carried guests Original steam winch entering the machine room, here the tripple expansion steam engine cylinder covers (2200 Psi) machine control stand a look into the crankrod section the machine telegraph receiver gave orders every few minutes, was continuiously in action, here a young lady is driving the engine round about midnight, a shot at the bridge deckhouse and finaly arrival back to the point of departure at 01:30 past midnight Nils

    Short excursion to Hamburg Harbour... Some 50 Km from my home.. Yesterday evening my wife and I had an invitation to take a river trip with the live museum steamer and steamship-icebreaker, (built 1933) "Stettin" on the Elbe river. This weekend was the 828 th Hamburg harbour aniversary, and the ride went from 21:00 to midnight. It was rounded off with a beautiful firework over the harbour, and to be watched from board the ship. The selfmade pics I would like to share with MSW fellow members in two parts.... Nils Part 1 Maritime museum pier at Övelgönne for traditional ships and work boats, (Elbe river This is the stem powered icebreaker "Stettin" at the river mooring ponton The "Aida Prima" cruise ship passes by The ship hull, all structures and interior make a very good impression Bridge Machine telegraph I had the chance to be down in the engine- and firing room at the boiler furnaces during departure. The sight of the steam engine at work, the reciprocating piston rods, crossheads and cam levers in live action was just amazing and wonderful. The orders for the machine control came down per machine telegraph, the accompaning "ring, ring" was continuosly heard in the background Bridge wheelstand with rudder position indicator and compass Other side of the river was the container terminal, and during the ride many types of sailships were busy on the stream.... to be followed by part 2....

    Beautiful done schooner Peter, I love the boats, they look real good, in fitting out and in scale. You mentioned in one of your posts .... the raw boat and the finished boat, just a question, if I may ask, is the raw boat made as resin cast, and what source are you using for it ? Nils
  12. Mirabell61
    Very neat and nice work Bob, all the frame joinings and some of the frame shimmings for perekt straking look great Nils

    Hi Rob, wow, nice to hear that you have dental laboratory experience (making and working also with silicone molds, etc... ? ) Yes, for the closed boats I`m intending to cast hull and (underneath) cover in one., whereby the boat will be in two halves, port and stb.. These will be fine faired and port and stb half glued together afterwards. For the open boats I wanted to cut away the inner portion of the cast on dummy cover, so only a handrail around the boat remains standing. For the bouyancy tanks, the seatings and the inner bulwark structure I want to make a wooden plug comprising the later. The plug will be used to hang it into the same negative silicone mold as for the closed boats during the resin-casting. I will prepare some pics of the whole procedure later on... It will still take some time and "learning curve experience" to start with the open boats..... When the casting procedure turns out OK, I`ll put on the "girlande" looking grab ropes around the boat outside, and lash on the canvas covers to the closed boats. Nils

    very nice boat Don, you did an excellent job so far, love those amphores down in the cargo hold... Nils
  15. Mirabell61
    Thank you very much Denis, I just received the two-component silicone for making the first mold for one of the boat halves. I`m waiting for the silicone to cure and to see if the seperation wax worked well. I`ll post some pics of the process later on Nils

    Hi Peter, thanks for sharing your pics of the museum...., The lines on the loft floor can really be tempting to build a real boat, the same approach as for a model... Nils
  17. Mirabell61
    Hi Greg, excellent work and super details ..... also nice color giving... Though it has something threatening for me, the close up shots remind (gunslinging midships section) me somehow of a fighting unit out of "Star Wars thrillogie"... Nils

    Hi B.E. nice to have a face along with the the fellow builder`s lovely model Nils
  19. Mirabell61
    Hi Mark, lovely model, very nice fitting out, masting, yards....., the fastening of the cannons per dowel is a good idea Nils
  20. Mirabell61
    Hi Albert, the wood tones used and the accuracy of your joining works, makes ones heart beat higher, whilst watching your build, it looks wunderbar Nils
  21. Mirabell61
    nice progress Dan, was there a certain reason for using the 5-side beads for the portholes, or just in lack of cylindrical ones ? Nils
  22. Mirabell61
    Very nice work Doug, also the white underwater coloring is a nice alternative to the coppering usualy shown here... Nils
  23. Mirabell61
    super investment castings Alex !!!, Nils

    Many thanks Rob and Michael, for your input on the boat covers and your kind comments and suggestions.... Rob, I think I understand how you meant the process you are explaining..... Unfortunately I did`nt find the detail "boat cover" on heritage lifeboats on the web yet.... Trust I have to start with fabrication of the boat hulls first, when I received the forming silicone and the resin for casting.... Michael, I think there is some kind of support element along the centerline, probably a spar, or a tight spaned rope, also there is a connection line between the davits upper points, from which short strap lines could hold the canvas cover up. That is the way I usualy covered my dinghi cockpit when at the bouy mooring, or on the trailor over winter, to prevent sagging by rain and snow. In KWdG boats application I have wooden support cover under the "canvas" for shaping reasons. (last pic of my post #2332 ) I would be pleased if someone has a pic or two showing this detail on the actual ship better than the enclosed pic borrowed from the web... Nils

    Hi Peter, I like that detail "hauling the boat up", it looks great... it could just as well be "setting the boat out" Nils
