It’s a spiral rod. Type I moisture resistance is a stellar quality. See how much you know about different glues by taking this quiz. As for time I usually leave my blanks in string for three weeks before continuing with the process but I have a friend who is happy to continue within a few days of gluing up. (Vince Brannick), As I posted yesterday, DAP Weldwood still makes resorcinol, it's available from several sources.

Until about 10 years back I worked for a while with a mob that made polar fleece and Gore-tex mountaineering clothing. The dust can clog the pores in the wood and greatly reduce glue penetration. Note that the claret color is in evidence in the very thin traces. (Gary Marshall). For wood gluing, the volume of phenol-resorcinol used far exceeds straight resorcinol. My main question was really about moisture testing. Wonder if anyone who uses resorcinol has used it on darkly flamed cane and/or on impregnated rods and seen any color variations as a result? It is decent strong stuff and I have used it for various jobs in the past but it sets up much too quick for my speed of assembly. It is expensive but mine has stayed good a long time (years) kept in the refrigerator. What are the Advantages of Resorcinol Glue? I have planned on sacrificing the first coat of varnish at times.

I've glued up 2 rods with the new Aerodux resorcinol glue and I want to give the list a brief report on my experiences. It sounds worse than it is. Both surfaces can be roughened with a quick pass of a rasp. Paraformaldehyde decomposes to formaldehyde which is carcinogenic. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage. All in all, the stains worked poorly  on rod shaft - blotchy - may have been problem with glue not totally removed.

With the Aerodux I use the glue line is a plum/brown color perhaps the pure resorcinol is more distinctly purple? (Bill Walters), I'm wondering if that Resorcinol can stand 350 for say ten minutes? This would assume the stain would not preferentially migrate to the fibers. Resorcinol market by end-user industry (building & construction, healthcare, automotive, electrical & electronics, dyes, explosives and others). (Bob Brockett). As the name suggests they supply  spares and materials to Aero fanatics. However, removing them does save weight! Its kinda pricey unless you can find small quantities, but its worth it, IMHO. Failure can cross the glue line, but the glue line cannot be the failure point. Make practice joints and test them to destruction. Particularly liked the observations on planing Vs milling + heat treating regimes. Just so no one mistakes my color names for wrong colors, they are from that other coloring savant system, Crayola's red, orange, yellow, green, blue, purple, brown and black, and has been since 1903 or so. It may have been a change of manufacturers, and it may have actually been an improvement. The Spanish word they use for the process is "change" (cambiar) not "return" (devolver) which gives a lot of insight on the way the situation is thought about here. (John Rupp). Additionally, rising usage in applications like UV stabilizers, etc., coupled with inherent advantages offered by the chemical is anticipated to add to the growth of the resorcinol … These days there are a range of glues available. As a courtesy (BE NICE!) Would any of you know of further experiments to get rid of those damn, purple railroad tracks? By weighing again, after a long time, I’ve found the bamboo regains moisture to the tune of about 5%. (Brian Creek), The glue showing up on the rod after the varnish was a problem this is what I did. Its amazing what you can get in a few minutes with Google. Repeated skin exposure can produce local skin destruction, or dermatitis. After 24 hours I have it out of the string and sanded. If in fact the catalyst is Paraformaldehyde (and that makes chemical sense). (This can be an advantage when expecting repairs. Now, if we could just find some 4-year-old genius chemist to permanently lighten (or change) the cured color of this stuff, we'd all be in rodmaker heaven. A light duty staple gun such as the Arrow JT21 works very well. (Timothy Troester). (Michel Lajoie), Bamboo is not wood but is a "woody grass". Resorcinol adhesives have undoubtedly become established as reliable construction adhesives since they combine ease of use with the advantages of high strength, durability and long storage life. Even just gloves and safety glasses make a huge difference. I’ve determined that a typical culm, in MY basement, has about 6% moisture. They don’t show right away, but show up a couple months later. Fast setup time (especially for "Fast" formulation) Fairly expensive; Those dark resorcinol glue lines (Frank Stetzer, Hexrod, Taper Archive, Rodmakers Archive) "Moisture content of wood is most important and should be from 8-16%, preferably within the 10-12% range".

It shows the black glue line, but I chose the particular spot on the shaft because there is an area where I left a trace of glue on the shaft before varnishing. (Tony Young). Inflammation of the eye is characterized by redness, watering, and itching. Liquid hardener leads to thinner glue lines; Cures at cool temps; Long shelf life if kept refrigerated; General resorcinol toughness; Disadvantages. Repeated exposure of the eyes to a low level of dust can produce eye irritation. I was interested in your comments on glue usage from past UK makers. This can be observed on Mr Garrisons rods built after the late 30’s, many Phillipson rods, Gillums later work, etc. Another problem I've had with resorcinol is even after sanding the glue off, after varnishing and time somewhere a resorcinol stain shows up on the surface of the rod where I didn't get all of it off. (Tom Smithwick). Perhaps if enough people begin calling Chinese Red Goldenrod everything will work out the same in the end. And my brow gets heavier when I ponder the color puce. (Chris Obuchowski).

This is a list of various types of glue.Historically, the term "glue" only referred to protein colloids prepared from animal flesh.The meaning has been extended to refer to any fluid adhesive.. (Don Anderson), Reminds me of when I first started tying my pheasant tails with Uni-thread 6/0 “Claret” color more than 20 years ago. I discovered this right off so you will be able to distinguish this also. Considering the problems I had with nodeless rods using every other glue that's really saying something but the sentence in "the bible" about it being purple prob stopped a lot of people from even considering it and I tended to try to get to the bottom of what this purple thing was to the point that I was convinced that half the world was calling what I saw as claret purple. If they don't have resorcinol, it would only be because most people would prefer epoxy for most applications where you would need the other. For myself, I did just purchase a pint kit from Aircraft Spruce, so I'm okay for now. I like the idea and would like to see it look as authentic as possible. For the second rod I added 10 percent denatured alcohol by weight to make it a little thinner. The failure should be in the wood each and every time. The glue does darken with age, and so glue lines do look like they "grow" over time. the liquid resin is an alcohol-water solution of a partially condensed resorcinol-formaldehyde resin containing a suitable reinforcing cellulosic filler.

They charge a reasonable price for the product, so it cannot have anything much to do with bottom line. (Chris Obuchowski), Wear gloves. Aircraft failures have been recorded where the cause was cited to be poor glue selection during construction. The resin appears the same as what we are used to, while the hardener is a dark brown goo about the consistency of molasses. Excess glue shouldn’t be completely wiped away, as you need glue at the glue line to be absorbed into the wood. you will have to be gentle with it. The resorcinol polymer of claim 1 or 4, wherein said acid is mixed with said resin in an amount of from about 2.5% to … They sell in pints, quarts and gallons.

Skin inflammation is characterized by itching. I would wait a couple more days. I’m looking for info about Resorcinol glue, I came across this web site for aircraft building supplies. I have also used Aerodux for my last two rods with very satisfactory results - nice thin even glue lines! First of all I stopped cleaning the glue from the blank with sand paper and stated using a file. We call it that because we are selling you a full gallon of the liquid resin (9#), plus the appropriate amount of powder hardener to catalyze -that gallon, which = 1.8. Approximately 50% of resorcinol is used in rubber products. That is one of the joys of resourcinol. There might be other sources besides Aircraft Spruce now. The amount of tissue, damage depends on length of contact. This cost advantage apparently is achieved without any significant loss in joint performance. 11. The global resorcinol market size was valued at 59.0 kilotons in 2016. Also note tests conducted by a list member, whose name I apologize for not recalling immediately, suggesting URAC rods are slightly stiffer than those glued with other adhesives. Repeated or prolonged exposure to the substance can produce target organs damage. Good stuff there. After a thread colour discussion with a customer in the UK who wanted a lavender colour that in Canadian English turned out to be Royal Purple, for colour I finally resorted using the numerical values for the primary colours red, blue and yellow and plugging them into Photoshop. Then I started examining close after first varnish. Bamboo Tips - Tips Area The only downside is that it will turn jet black. (Doug Easton). We will see what happens after a couple years.
