    To quote Captain Jack Sparrow: "It's a very pretty boat". Bravo Chris!

    For the record: tung oil and linseed oil are highly unsubstituted vegetable oils. They "dry" through oxidation. Oxidation is exothermic and thus the fire potential if stuffed in a ball without proper ventilation. Used engine oil will not ignite from oxidation because it has already been thoroughly oxidized in your crankcase. Solvent soaked rags are not heat generating but if the room temperature exceeds the flash point of the solvent and a spark source is nearby fire will result. Keep rags with drying oils and solvents away from your home Jaxboat

    Hi Chris, Great to see you back. Best of luck in your new ventures. You have not mentioned your canine apprentices. Hopefully they are in fine fettle Best Jaxboat

    I am very cognizant of acrylic resin properties as I sold acrylic water borne and solvent borne resins to paint companies (including artist paint manufacturers) for years. "Acrylic" refers to a whole family of polymeric emulsions and resins that differ by molecular weight, composition, water solubility, solvent and alcohol tolerance, flow and leveling etc. Additionally, additives also enhance paint properties. My favorite brand currently is Vallejo. I think they have an excellent balance of properties. However, while brushing and spraying properties have improved immensely, they still aren't as good as an alkyd solvent borne enamel or acrylic solvent borne lacquer. On the other hand, the acrylic water borne products are much more environmentally friendly and offer easier cleanup of brushes. I have used Jo Sonya paints too and really liked them for their brushing properties (haven't sprayed them) and vivid depth of color. I have not found an acceptable water based product for priming metals especially brass. I am going to try Ed T's Rustoleum process.

    But Druxey, me thinks not enough suffering and existential angst in getting them right with this method. Jaxboat "That which doesn't kill you makes you stronger" -Fred Nietzsche

    Jaxboat's rule no 2: Chances are that anything that reacts chemically at room temperature quickly will also react with you!

    I have experienced high temps with CA if the part was wet. Best Jaxboat

    I agree with all of the comments on this blog. I also had some plan reading issues but they were minor and I was able to recover quickly. I am building Confederacy which is a big model and the building slip has been a very welcome tool. I also use an Amati hull clamp but it proved too small for a project of this size and weight. However, it will remains my choice for more modest sized models. I also purchased and use the paint brush stand which again is very nice. I have my shipyard in my garage in Northern Florida. Our humidity is world class in the summer and so far no issues with the MDF. Best Jaxboat

    Hi Rusty, Great work as always. Your ladders look great. How did you cut the grooves (file? razor saw?, table saw). My first attempts at the confederacy method were OK but not as nice as yours. Best Jaxboat

    The shoe dye that Druxey mentions work very well to simulate ebony. It does have one drawback. The stuff has almost zero surface tension and will flow through any size aperture including a tightly closed bottle cap if the container accidentally falls on its side. Trust me, I know! RE carbon black: a most interesting material. The stuff is extremely hydrophobic and is very difficult to disaggregate and disperse in water (special wetting agents are required). Carbon black is rated by particle size and "jetness" i.e., blackness. These properties are controlled by what is combusted and the amount of oxygen used during carbon black manufacture. Best Jaxboat

    Canute makes a distinction between enamels and lacquers. For the record: Lacquers can be re-solvated after application. Nitrocellulose, CAB and thermoplastic solvent borne acrylic resins are commonly used in lacquers. Enamels cannot be re-solvated readily after they fully cure. Both enamels and lacquers have superior wetting properties to water borne acrylics although the acrylics are rapidly catching up. Water is just a lousy solvent with very high surface tension (beading). For my money Colour Coats are the best solvent borne hobby paints I have ever used. They brush well and spray well after proper dilution. On the water borne side Tamiya and Vallejo are my faves with excellent pigmentation and wetting for a water borne. I use water borne paints whenever I can for the ease of use and lack of solvents

    I think you could use a solvent based paint with no issues. Paint adheres to a surface through one of two mechanisms: mechanical adhesion or chemical adhesion. To get good chemical adhesion you need excellent surface wetting which a solvent based paint provides. If you use a water based paint on brass that has fingerprints on it, the water based paint will not adhere properly because it can't "wet" the surface properly. I like the alcohol vinegar combo before applying water base paint and I will try that. Sanding would provide for mechanical adhesion in all cases but some parts are so small that it would be tedious or impossible. IMHO Best Jaxboat

    Don't know what blue pigments were available in 18th century other than ground lapis lazuli (ultramarine). You could certainly tone that down with a little carbon black. Any comments, Druxey. The frieze is beautiful, Chuck! Best Jaxboat

    Interesting topic. As a kid I used Floquil but mostly Testors, From everything I have read Floquil paints were superior. Stricter VOC regulations effecting both what solvents you can use and stricter postal regs as well as ever improving quality of Water borne paints like acrylics have reduced demand and commercial viability. I really like Vallejos and they make a water borne line sold through Micro-Mark that have the same colors as the old Floquil railroad colors. Give them a try. I have to chuckle about people buying old Floquil metallic paints. Solvent borne metallics would be the least stable of the old solvent borne paints Best Jaxboat

    I would add one more step to Chuck's comment. Make sure the false deck is thoroughly dry before you plank. Good luck. Great suggestion by Chuck and Druxey. Jaxboat

    Totally agree about the need for safety. A material safety data sheet (MSDS) is the place to look for info in the US. Jaxboat

    Thanks for the info Chuck. Formaldehyde is really nasty. Most likely the other producers use a phenol formaldehyde resin saturant. The heat from the laser unzips the resin and releases formaldehyde. Some of us are old to remember when we dissected frogs in Biology class in high school . The frogs were all preserved in formaldehyde!

    Pigment is prepared for incorporation into paints and inks in various ways. The general term is grinding. Energy is applied to the pigment to disaggregate the particles and wet them. I have made water borne acrylic house paint in a lab with a Waring blender. The finer the pigment the smoother the finish. House paints from home depot are not going to have the finer sized pigments of a good quality waterborne paint. BTW: not all waterborne paints are latex. Latex emulsions are totally insoluble in water.They are stabilized in water as emulsions by surfactants (soaps). Some waterborne paints have limited water solubility and are called water reducible. Such solubility aides in pigment dispersion and flow and leveling during application either by brush or spray. Waterborne acrylics are very sophisticated and chemically complicated beasts.

    Hi Telp, I was in the US Navy when they still used red lead primers and I agree with you. They were a dull red color similar to Red Ochre. Certainly they were not the eye-popping red on the video. RE: Ochre Pigments: they can go from black to red to brown to yellow. They are all oxides of iron. The color is made by changing the oxygen level in a furnace as well as the moisture content.

    Excellent film. Thank you for sharing with us. I did not know that red lead was that brilliant. It will be interesting to see how she looks once the linseed oil "dries' (oxidizes). I would imagine they used turpentine for brushing consistency. I wonder if lead poisoning was an issue for the crew who painted her or the yard workers who mixed them. Today if you opened up a bag of red lead pigment to do paint grind you would probably be in a hazmat suit! BTW: you must grind (apply energy) to the pigment/ paint vehicle mix to wet and disaggregate the pigment particles into their smallest size. This optimizes hiding and stability. In water borne exterior house paint the pigment is ground in a water soluble resin know as a pigment dispersant. Once the "grind" is finished it is "let down" poured mixed into the primary waterborne polymer emulsion paint vehicle. Best Jaxboat

    Frankberge: Thanks for the info even if it was sad. Now I can put off saving for the home addition I would need to display it. I was in Stavanger several decades ago. Charming and beautiful place. Remember you could have reindeer about a dozen ways when you went to a restaurant. Ulises: Sorry you will be disappointed (for now). Was looking forward to following your lead on the build Sounds like some evil marketer is the problem Best Jaxboat
