Brett,
Wow I'm glad I am not the only one who creates fires in the shop, My best was fiberglas resin mixing cups in the trash can with a nice dose of paper towels. Sounds like this product does not need a space in my shop. Your chair story is great, Kinda sounds like my totem pole from hell project. I have been injecting it twice a day for weeks now and caulking and painting. Tomorrow or the next day when I find a sucker , I mean a helper. I am going to invert it on its heat and pour away, This should be interesting. I can only imagine what was going through you hGad with that chair and how would tell the customer that you didn't quite fix it but just burned it down. Glen

Cyanoacrylate is.....super glue.? You can add thickeners and solvents to it to alter flow-out and cure times from the little bottles you find on the racks, but the biggest issue I've had is that CA has a shelf life and lower cost CA glues tend to have diluted performance, and the good stuff is crazy expensive on a per-unit basis. I buy a big bottle every quarter or so of Starbond and keep it in the refrigerator and pour off into 2-oz dispensing bottles to keep it fresh and active. I go for the lowest pricing between Mohawk, Starbond, and 2P-10, sometimes Rockler's Stick Fast (right?) or other house brands depending upon who is running sales as I view the premium brands commodity products. I also prefer the aerosol activator over the squirt-bottle variety, seems to be more accurate, less messy, and ends up about the same cost over time.
My favorite use is CA in insect damaged wood. I once had to repair a broken leg on a French Provincial piece imported for high end resale from the 1700s, thinking it was the intersection of bad design and fat people, until I opened it up and found termites had eaten all the soft wood inside the paint for about a 6 inch distance. Filling diligently with CA the first 2 ounces, wicking into the wood and exposing lots of curing area, the wood started smoldering in the chair, smoking out the pores and the heat outside the paint became so hot after 30? seconds we poured another 4 ounces in to choke off the oxygen supply, absorb the heat, and moved the chair near a water hose. That was a very scary afternoon on fire watch.
Well did a bit of digging on what I can get from my wholesaler and found all the basics including plastic resin. I did not find resorcinol but did find Cyanoacrylate. I have never heard of it , anyone knows what it is and its application? Thanks

Sorry, I thought you were starting on the 20¡¯ long DF project. You probably do not want to see reddish brown glue lines on that.
Imran? ? Mark and everyone, Thank you for all the feedback, To clarify I am making three curved ribs that are going to raters for my shop overhand at the door. The seat cut to seat cut 8 ft with a rise of 14 inches, to me a very easy bend. The net finish is to be 2.5"x 7" give or take. one of my suppliers has 1/2"' x 3-1/4 clear pine sized in stock so I can skip the planing process and at my cost of About 100 per beam, to spend a couple of hundred more to do a glue test between West and Plastic resin or resorcinol is worth it just see what's better.

The resorcinol glues today are of a much lower formaldehyde content then in the past, still a likely a concern but not sure if it¡¯s any worse then the others chemicals you would be exposed to in a woodshop.?
I have used it a little over the years for where I needed a hard glue line - bent laminations, burl veneers but I have also used yellow quite a bit with success. Would still recommend urea for a bent lami, however have used yellow and just added a little extra bend to account for the spring back which works if you are designing your own pieces but may not if you are working to an architects specs. I have some walnut burl tables and a Humidor that I pressed with yellow about 25yrs ago and they are still good. I also worked n a corporate/custom shop where we built 100k + boardroom tables and don¡¯t remember using anything special.?
With that said, today i would use slowset tightbond at a min on flat panels, it sets up pretty hard for a pva, no special mixing and I already have some, next would be unibond 1 which is an even harder pva and lastly urea (although I may use urea anyways as I am getting more paranoid in my older age).?
And i would never use epoxy unless it was a boat...?
