smooth on

[Beanbag]

I read here that 2-1 smooth on is stronger than 1-1. Looked for info and found it  conflicting . Binghams is also confusing.??? Is it 2 pt's #1 (a) to 1 Pt #2 (b) or 1 pt # 1 (a) to 2 # 2 (b). Thanks Jim g

I never had a problem mixing 50/50.

[Roy from Pa]

2 A to 1 B is stronger

[LC]

I never heard about it being stronger, not saying it isn't but I recently read on the label mixing heavy one way or the other made it more heat resistant. Either way I've only used 50/50 and never had a single glue failure.

You boys from Morgantown live a sheltered life, I'm surprised ya even have internet service down there, LC:)  

[Al Dean]

I never measure exact.  Only by that looks about right.  Always make sure I have as much or more of A than B.  All epoxy I have ever used the slower the cure the harder the end result.  I suppose there is a point where you did not use enough hardner though.  I'd go 1/1 because what good is a 1/2 can of hardner when you are out of resin.

Roy is correct fer once...    


EA-40® Clear Amber Epoxy is an unfilled low-viscosity epoxy adhesive that can be spread easily in thin films that are
almost transparent after curing. EA-40® has a long pot life and cures in 24 hours at room temperature to provide good
mechanical and electrical properties. Mix ratio is 1:1 by volume. When mixed 2A:1B by volume, EA-40® will achieve
greater heat resistance and improved physical properties.

LOL Roy we just got it last month! Using a
Satellite  made from a 55 gallon metal barrel lid, a old transistor radio, speaker wire and of course Smooth on to hold it all together.  

[kennym]

Oh, I keep the part A in the qt size if you need some...

I always just use 50/50, never had a glue failure, only a couple operator malfunctions....

[Beanbag]

Hope you all got the wiring correct. lol Thanks for the info. I'm hoping to get some pics after I get er dun ,I'll try 2-1 for starters. Thanks Guys Jim G

I've got a 60/40 mix curing in the oven right now and will be stressing it tomorrow, unless the wife kills me in the morning when I give her the belt sander alarm 2 hours before shes ready to get up.

I mix 50/50 by volume myself. I buy plastic cups in sizes 2 oz and 3 oz and fill them to the top for equil volumes. I just Fill a 2oz and a 3oz of each part and that makes 10 oz of glue, On my first few bows I went thru 12oz of Smooth On, lots of squeeze out when I applied air pressure...I am getting better But I still put too much glue on the lams..

[Roy from Pa]

You glass bow boys are always sniffen glue, always worried about your glue mix. Ifin ya made real bows from staves, ya wouldn't even haf-ta worry about it...  

[bigbob2]

I mix mine 70g/58g by weight for a four lam straight laid longbow and works fine.Hey Roy we dont have to dodge worm holes in our glass bows          

[Beanbag]

Actually you can made a worm hole look pretty good under glass! lol Going to try some eastern red cedar for my first veneers. My boys were stationed Fort Lost in the woods MO awhile back. They picked up a bunch of old growth cedar and made some rustic tables out of it, pretty nice. Might be able to find some good grain in the stuff they brought back.I'm going to try Bobs method, might save a mess on my part. lol thks

[Roy from Pa]

Bob it hain't a real bow unless it's got some worm holes in it:)

[bigbob2]

Guess I could always drill couple holes in the lams then.
