resorcinol glue advantage

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. Years and years ago I was a cabinetmaker and millworker. If you are used to epon, it might catch you by surprise. The following is an excerpt from both the Zing and Cloudster building plans (as of 7/20/2014) : All wood surfaces to be glued must be free or dirt ,sawdust, and oil. Its use has declined since the 1990s due to the ease of use and versatility of epoxy glues and fillers. (Timothy Troester), Resorcinol is very tolerant to heat have no fears here.

The failure should be in the wood each and every time. None of this really matters of course but it's a question that's rattled around for a long time and if somebody is going to the trouble of replicating the colour it does matter that the colour is established. I have planned on sacrificing the first coat of varnish at times. Advantages of Epoxy Countertops and Durability-Epoxy is exceptionally durable and lasts for years; no re-application necessary-Epoxy rarely cracks and it’s almost impossible to destroy short of a natural disaster-No other material compares to epoxy when it comes to maintaining a high-gloss look-Pattern, color and design possibilities are endless It is however more than adequate! The glue does darken with age, and so glue lines do look like they "grow" over time. If you look at this link of Crayola colours it may help: You'll see purple mt majesty, that's not resorcinol. Now considering we are RODMAKERS, the keepers of the keys as it were who concern ourselves with planing strips to within 0.001" and agonize over the colour of wraps on vintage rods and other details I should have thought that people would have been interested in knowing the true colour of the glue lines of Garrison's and other's rods rather than continue under a misunderstanding of such a basic thing but it seems I'm wrong. Advantages of Melamine Glue. Please be aware of the Material Safety Data Sheet on this: http://www.sciencelab.com/msds.php?msdsId=9927382, Very hazardous in case of skin contact (irritant), of eye contact (irritant). 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. The Orvis rods, because they are/were impregnated with Bakelite may not have had the same amount of absorption thus limiting the purple color at the glue lines. Cascamite was the adhesive used by the old rodbuilders e.g Hardy, Allcocks etc. (Frank Stetzer, Hexrod, Taper Archive, Rodmakers Archive). (Mike Biondo), Just emailed them to see if that's a kit of a gallon each of the resin & catalyst, or 1/2 gallon of each for a gallon total. (Harry Boyd), The active ingredient is paraformaldehyde. 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 … We also offer resorcinol-based resins, as well as melamine-based resins. It was then that I had to stop and wonder if people are calling something purple that I'd call claret but I'm just guessing. [citation needed] Well, I've never used Resorcinol, and don't know nothing about its color. Most people do it before final planing, although some do it afterwards. Slightly hazardous in case of skin contact (sensitizer). (Chris Obuchowski), Wear gloves. (John Channer), Resorcinol thinned with alcohol does penetrate into the bamboo fibers, but only at the cut ends (think of thin glass straws and capillary action). Repeated or prolonged exposure to the substance can produce target organs damage. Comes in two parts, a liquid resin (part A) and a powered catalyst (part B). I admit I’m probably the only person in the world nostalgic for the true purple glue line. (Brian Creek), The glue showing up on the rod after the varnish was a problem this is what I did. Let me know if any further questions. you will have to be gentle with it. (Paul Blakley), That’s cleared it all up nicely!

It's a ratio of 3:4 (I can't offhand remember which is which, but it says which on the can), with one part denatured alcohol. They can be reached at 800-861-3192, or at aircraftspruce.com. I really liked it, but it didn't seem too popular with the rodmaking community. But then again, as John Rupp mentioned a few days ago, AircraftSpruce.com sell it in pints for $19.90!!! He’s got two long articles about bamboo. But most of us, ahem, guys are wired to not give much hoot about "colors" aren't we? Years ago, I spliced a few strips before planing, and later heat treated them. We will see what happens after a couple years. (I was expecting a quart total.) (Vince Brannick), As I posted yesterday, DAP Weldwood still makes resorcinol, it's available from several sources. That's how you get an eyeful or a snoot full.

The amount of tissue, damage depends on length of contact. Look online for Aerodux 500. When gluing with Urac, many of us replace the powdered component with Ammonium Chloride. you can straighten out out twists after weeks. If in fact the catalyst is Paraformaldehyde (and that makes chemical sense). The only downside is that it will turn jet black. Craft projects or repairs requiring a flexible, quick and permanent bond. (Neil Savage), And it's good stuff. After 24 hours I have it out of the string and sanded. With a little over 100 rods glued with Urac I have a good idea on how the rods made with it will perform. This is however purely subjective!

It’s true that hide glue isn’t very water resistant, but this is more an advantage than disadvantage because it allows repairs to be done more easily. Even if you are building nodeless, I think the heat treating is done before scarfing and gluing. (Brian Smith), If I use resorcinol on a blond blank, will the glue stain (discolor) the flats? We only used resorcinol, and although the purple stains have long gone away from my hands and arms, I do still have my coveralls which are covered with purple globs and stains!!!

Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract, characterized by. 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? Surfaces cut with a sharp blade or saw are good, the pores are open. Outside conditions are not a deterrant for using this glue. A secondary benefit is that it cures at any temp above 50F which means  I can leave everything in the basement shop even in winter. they will supply it to us in quart kits. does it have the same character as wood... just a question!

(Chris Obuchowski), Wolfram Schott covers this in his "Bamboo Under the Microscope" which can be downloaded from the Power Fibers site. Sales - Service I mostly use epoxy these days, because of the long work time, long shelf life, and reliability. Aircraft failures have been recorded where the cause was cited to be poor glue selection during construction. (Tom Smithwick). DEVELOPMENTAL TOXICITY: Not available. It's my go to rod, has been absolutely thrashed and was once use to fend off a tiger snake (I also ran backwards very quickly with not a single jot of sangfroid remaining), not a thing wrong with the rod.

By weighing again, after a long time, I’ve found the bamboo regains moisture to the tune of about 5%. Those who attended the Catskill Gathering may have heard Jim Krul saying that he would like to see a Garrison taper rod built on the Garrison equipment now in the museum. Shipping isn't cheap on this stuff. This would assume the stain would not preferentially migrate to the fibers. Though I haven't tried it yet, I'm curious.

Notice the black or reddish glue line . They charge a reasonable price for the product, so it cannot have anything much to do with bottom line. Advantages. CARCINOGENIC EFFECTS: Not available. I think that is a ONE-gallon amount for $115. Would a similar glue result diminish the ability of the cane to accept finishes. They also have a long storage life. What's more it says very clearly that this particular resorcinol is two part, a dark wine-coloured liquid and the catalyst. The Cascophen PRF are the phenol resorcinol resins; there are several. The Vampire jet was built in 1948, these old boats I used to work on were all well over 50 years old. (Tony Young). It is a good bet the oil based stains would not, at least some of them.

My main question was really about moisture testing. When the parts are clamped together, excess glue should squeeze out around the entire parameter of the joint. They have always made the small amounts available as a courtesy to rodmakers. (Don Anderson), At SRG this year I picked up some resorcinol glue to try. It is one of the few adhesives around that stay strong when wet for extended periods. We specialized in reproducing custom redwood windows, doors, sash and other millwork for victorian homes. In the 6th para same page it goes on to say that some don't like the dark wine coloured glue line that is unavoidable if one uses phenolic resin glue.

However, unlike epoxy, it does not have gap filling properties, requiring joints to be close fitting and clamped under pressure to … when it is dry the timber of the sound you hear when you run you hand over the section will sound different than when yet damp. I have been informed by Chempoint that Aircraft Spruce buys from them regularly so that shelf life is not an issue. Another one that's not quite right but close enough for this level of explanation is brick red. Sometimes you can find resorcinol at boating supply stores which has turned over more recently than at most hardware stores. When I was starting out making rods, I had a boss that was into home built aircraft. Peter McKean, do you remember the colour of the Phillipson Smuggler? So it never gets back all of what you’ve driven out. This cost advantage apparently is achieved without any significant loss in joint performance. (Tony Young). (Chris Obuchowski).

That glue is Resorcinol or a cousin. Where are all those chemical engineers when we really need them? The question in this time frame, is where is Borden's resorcinol glue available if someone does want to use it? (Tom Smithwick). I'm just curious if anyone has tested the moisture level in a raw culm versus a "dried" blank. (Tony Young). I mix by volume, and use plastic disposable picnic teaspoons.
