2021 what did you do today?

[Buemaker]

Was it dark in there?

[Crooked Stic]

Bue me thinks Roy in the dark a lot 

[Flem]

I don't use much EA-40, but I was needing some thick epoxy so I  grabbed it. This stuff is 4yrs old!
It's also still good!  I opened the hardener and after the initial stank evaporated in a minute, it had the normal Corn Nuts smell.
I'm using it in a non stress application, so even if it is compromised, which I doubt it is, it will not matter.
Don't throw the stuff away because its supposed to have gone "bad"
Like Mr.T said; "Rules are for Fools"

[Roy from Pa]

Mine is 2 years old and I worry about it...

[Flem]

If it's still good I'll let you know in 3hrs

[Flem]

After 1hr @ 120-130deg

I could barely get a finger print in it

[Flem]

Extra material popped cleanly out of the mixing container @ 2hrs
Already difficult to flex

[Roy from Pa]

Great news.

[Longcruise]

Didn't Smooth-on recently modify their shelf life statement?

[kennym]

Didn't Smooth-on recently modify their shelf life statement?

They told me 2 years now. That’s prob unopened but prob has a safety factor for them also.

What I use is never white like Flem tho

[Crooked Stic]

Two years on an open can.

A little hard maple some black dye Cactus juice some vacuum and curing heat.
And you can turn plain looking wood to look like something. And here is a further back shot of the big burrs.

Nice stic

I got fired up @ the Classic looking at some of James Parkers bows.
I've made 1 BBI R/D from roy's setup.
I want to try a Recurve with Boo back and Ipe belly with maybe Boo flooring core with the riser built in.

Last observations on the vintage EA-40. Mine is white because I put 1 drop of colorant in it, which is more than maximum considering the amount of resin and theoretically should weaken the mix. Speaking of mix, I used a 2A/1B ratio.
After cooking @125deg for 3hrs and after cooling down to 76deg, I could not break this disc without more leverage than my thumbs and forefingers provide. It's about 60% of a 2.5"dia disc, maximum thickness of .070".

I would use this "old" glue to build a bow without hesitation

Elegant.   

[Roy from Pa]

Mark that is a sweet looking profile..

Thanks Flem makes me feel better about my glue.

I use ea 40 mostly for tip overlays but sometimes to glue a riser on.

Mike they seem a little big to me but maybe not to others.

Sharp looking bow though.

[kennym]

Stic, is that a farmer's bow?  Looks a little John Deere ish!

Flem that should be plenty strong...

Mark, that's gonna be cool!

[Crooked Stic]

Kenny never thought of it as being a farmer bow. Was a farmer growing up. We always said tractors were like watermelons Keep the Red and throw the Green away.

ROY big burrs may make good conversation.

[kennym]

Mostly green around here. For a long time every red one for sale said good TA. bad TA, or needs TA... 

[Flem]

Was mostly green around here until this morning..........
