Hi Druxey, Love this discussion. White lead carbonate was used in house paints (exterior) as late as the early 70s. It had the advantage of resisting mildew. However, it turned grey if exposed to sulfur fumes H2S, SO2. This was a common problem in Southern US regions near wet lands (PC term for swamps). I would expect a similar situation in any marine environment. Red lead (minion) is Pb3O4. PbO is Yellow lead oxide. Bizarrely, PbO is still used widely in the US for painting lateral delineators on roads. In the case of Victory, perhaps some of the lead oxide was off spec and had a touch of red lead in it. Even a tiny amount would effect how certain people would perceive the color. Kind of bazaar, though. I can't envision Nelson fighting Trafalgar on a pink Victory/Victoria Jaxboat

2015 NRG Conference Update - MYSTIC
Jaxboat replied to Chuck's topic in NAUTICAL RESEARCH GUILD - News & Information
Great to see the Model collection at least in pictures. Mystic had many of these on display in earlier years. Not sure why they keep them out of sight. Best Jaxboat -
I did a little research on "Milk Paint". The binder is casein which, indeed, does come from milk. Many of the pigments they use were indeed available during the great age of sail. (iron oxides). Ultramarine is a synthetic version of Lapis Lazuli which was used in blue paint but was extremely expensive until the synthetic version was accidentally discovered in the 19th. Chrome oxide green was not available until mid 19th century, All of the pigments I saw listed were inorganic and very color stable under normal UV and temp conditions. Best aspect of these paints is their total lack of toxicity. I would be somewhat concerned about their durability from a UV exposure and moisture resistance standpoint. Jaxboat

Making Moldings

Hi Druxey Does the heating process permanently soften the blade or do you have to complete the filing while the blade is hot? -
Essex - Process and corrections to the new Model Expo Kit
Jaxboat replied to samueljr's topic in Wood ship model kits
The Confederacy is a much better bet. It is a beautiful kit. It still suffer from terrible castings like the Essex which is no fault of the designers. Chuck Passaro's company (Syren) sells a resin cast figure head and beautiful cannon replacements. Enjoy Best Jaxboat -
Essex - Process and corrections to the new Model Expo Kit
Jaxboat replied to samueljr's topic in Wood ship model kits
Hi Stefan, Check the date for the parts list. If it is recent, then the kit is the new version. The same holds true for the Instructions print date. The ship's plans were not updated to the best on my knowledge. Be aware that the laser cut parts were improved substantially and now fit but the metal castings remain awful. Best Jaxboat -
Fiebing's Leather Dye
Jaxboat replied to JohnB40's topic in Painting, finishing and weathering products and techniques
HI Greg, I can testify that dye spills are a disaster! The dye seems to have near zero surface tension. In my case, it flowed through the cap (tightened) when I accidentally knocked over the bottle and did not notice it had fallen over. What a mess . Since dyes have no solids like paint and do not form a film I know of no reason that you could not use the same adhesives on dyed pieces as you would on undyed pieces. My clumsiness is legendary so I have switched back to paint out of fear! Still, there is no denying the dye has a wonderful degree of "jetness" that is hard to obtain with paint. Best Jaxboat -
Fiebing's Leather Dye
Jaxboat replied to JohnB40's topic in Painting, finishing and weathering products and techniques
It gives an excellent jet black appearance but is very difficult to keep from getting all over things where you don't want it. It's best to apply the dye to parts before you assemble them. Best Jaxboat -
RE: Fatty acids. Yes fatty acids would have less acidity than Muriatic acid because the acid group's effect would be diluted (COOH in chem speak) by the long fatty carbon chain. For example Tall Oil fatty acid (the word "tall" in this context has nothing to do with height) is a derivative of pine trees. It is the active ingredient in Murphy's oil soap and is a C18 fatty acid.

Druxey raised my curiosity about beeswax with his comments on conservators wax. I was selling beeswax and its derivatives into the personal care industry at the time. I confirmed all of Druxey's comments with a beeswax/wax expert. Beeswax is a natural product with a very broad range of chemical substances many of which are not "wax". In the long term, beeswax does become slightly acidic. Do not know what the time frame is for the pH effect to occur. Microcrystalline wax is a 100% hydrocarbon based wax with no acid components either as supplied or upon aging. There are different grades of MC wax based on melting point range. I don't remember what the range is for the conservators wax. There are also different grades of beeswax also, depending if it was bleached to reduce color or distilled to increase melting point. If I was looking to finish a model with wax, I think I would choose carnauba, a plant based natural wax. It is harder than beeswax. For those of a certain age, you might remember Du Pont's Simonize Car Wax. It was almost all carnauba wax with just a touch of a hydrocarbon solvent to make it workable. "Wax on, Wax off", grasshopper . Best Jaxboat PS: OCD Chemist peeve - you "dissolve" wax into turps, not melt. You can "melt" wax with the proper application of heat

Essex - Process and corrections to the new Model Expo Kit
Jaxboat replied to samueljr's topic in Wood ship model kits
HI Bill, I was able to secure Essex replacement parts from ME very quickly once they were available (that was another story). A couple of suggestions: if you bought the kit directly from ME include your date of purchase and order number, call directly to find out what the issue is. Best Jaxboat -
HI Dave, I did not like it at all. I apply glue from a syringe device and I could not fill the reservoir easily with the stuff. To get the no run no drip viscometrics of No-run No drip you would have to have some kind of additive. Don't get me wrong, Titebond has an excellent product line. I would just use one of their conventional flow PVAs if it were me. Surprised about your comments about Weldbond. Isn't it a PVA too? Best Jaxboat

Essex - Process and corrections to the new Model Expo Kit
Jaxboat replied to samueljr's topic in Wood ship model kits
ME is either laughable or sad or both in their inability to carefully proof instructions or even labels for their kits. My Mark one Essex kit label said it was solid hull. Obviously, someone printed off a label from their old Essex kit . They use reputable, talented designers then totally screw up on execution. I just don't understand them. Best Jaxboat -

Essex - Process and corrections to the new Model Expo Kit
Jaxboat replied to samueljr's topic in Wood ship model kits
Received correction package from ME. I made my request along the lines of what Terry said he received. The new laser cut parts look to be a real step up from the stuff I originally received and weren't made from "mystery" wood. I also received a new instruction book. I did not ask fro new plan sheets. Can anyone comment if I should have? While I appreciate MEs supplying the new parts, I would like to respectfully point out that they could have saved a lot of angst (and expense) if they had built a second prototype out of production parts to catch any problems BEFORE they shipped out the early kits.

3D printing tests (Form1+)

Interesting idea, Druxey. I think it would be relatively easy to design the right casting wax. You need precise melting, flow and set Best Jaxboat -
MDF for laser-cutting new frames
Jaxboat replied to rshousha's topic in CAD and 3D Modelling/Drafting Plans with Software
MDF gives off formaldehyde. It would be trivial from the amount in a model ship. However, I would not want to laser cut the material without a substantial fume removal system. Best Jaxboat- 25 replies

Hi Terry, Very encouraging. Did you have to enumerate what you needed or did ME offer a standard list? Best Jaxboat -
Essex - Process and corrections to the new Model Expo Kit
Jaxboat replied to samueljr's topic in Wood ship model kits
Based on comments here and the obvious availability of the kits now on ME's website, ME is finally shipping backorders. I wonder when they will make replacement parts available to early purchasers. I note that they have the new instructions on their site but not the parts list. Has anyone obtained corrected bulk heads? This whole situation is very annoying Best Jaxboat -
Hard to say without knowing the chemistry of the glue. I world contact the manufacturer and ask for a Material safety data sheet (MSDS). This document details the chemistry of materials and safety hazards, Maybe one first step is just to ask the manufacture what general kind of polymer he is using. This glue maybe a PVA with modifiers to make it easier to apply to a wall without drips. Such a modifier would change the "feel" of the polymer. If the chemistry is PVA or Acrylic I would say it should be ok. Another slower way to determine suitably is to coat fabric as you would for your sails and stick it on the most sunny window sill in your house and see what happens. Does it yellow, does your sail become "brittle" etc. One year should be enough. Best Jaxboat

The "glue" you are using may be a PVA (white glue) based. I think the wall paper you are referencing may be what we would call "vinyl wallpaper". Most true paper is non woven but some are woven such as papyrus.
