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.

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.

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.)
