My osage backed Ipe experiment

[Osagetree]

:(  Hate to hear that. Thanks for the update and my fingers are crossed for your next attempt.

Psych, I used a plastic resin glue to build a duck boat a few years ago. It had a different name but I'm pretty sure it was basically the same as weldwood. At first I measured carefully each time I mixed up a batch but it was such a pain to get the ratio exact, so I started mixing by putting some water into a small cup and adding powder as I stirred until it came to the right consistency. I never had a glue failure doing it this way. I do remember though, that it did work better with lukewarm water.

I'm trying joe.    

I had to work 12 hrs Wednesday and Thursday night from 7pm to 7am and didn't get to sleep much when I got home this morning. That makes my already mistake prone brain extra clumsy. Ill wait to reglue it until tomorrow or sun when I'm mentally capable of being careful.  

[psychmonky]

Got her reglued and all clamped back down. That glue looks a lot better when you mix it correctly. I guess we will see tomorrow evening weather it stuck this time.

[psychmonky]

Well, to answer the question, No. It does not look better just because the glue is mixed properly. I'm beginning to think it may just be the glue... I don't know if it was just a bad batch or this particular glue isn't made to handle the stress that an R/D profile puts on the glue joint. All I know is that when I unclamp it I hear what sounds like rice crispies and in a few minutes it looks like this:

 

Now i KNOW people have used this stuff to make bows. The only two things I can think of are:

1:  The glue is just bad. I know it isn't expired, but perhaps that date is just a ballpark, or it was just a bad batch?

2: The "roller coaster" nature of the backing with all the humps and dips is too inconsistent to allow a strong glue joint. It takes quite a bit of clamp pressure to flatten out some of those high spots, so I'm sure they are pulling against the glue pretty hard. You would think that the "low" spots would be glued fairly solidly though...

I'm working on acquiring another piece of osage, and I'm going to build a hot box and get some Smooth On. Lets see if eliminating all of these variables can't produce something I can at least glue a handle to and start tillering.

No, it isn't. The big brown globs you can see are sort of the consistency of a rubber eraser. SOME of the stuff that was squeezed out was hard and brittle almost like really thin glass. That stuff breaks apart when you try to peel it or bend it.

I know it was mixed well, and it should have had plenty of time to cure (36 hrs+.) I even had a space heater next to the bow so the temp was 80+.

I dunno.

[Osagetree]

Oh no it didn't!    

I didn't catch the name of the glue... One thing is for sure,,, it aint worth nut'n.

Remember, to much pressure will squeeze out all the glue (starve the joint).

Where ya getting your osage from?

[psychmonky]

It was weldwood plastic resin glue. I had seen a thread a while back that mentioned it, and a couple of different people had apparently built bows from it.

My new piece of Osage is coming straight from Kennym. THANKS KENNY!!! It should be a lot closer to an actual backing strip. The only thing good about any of this is that my original piece of Ipe is still useable. Ill get it stuck together somehow!

[DVSHUNTER]

That sucks. I've been there.

[joekeith]

If ya want to borrow a hot box I've got one you can use for a couple of months.  I live in Dittmer if you'd be interested let me know....

Scott,
The UBM Festival is in,Jeff City beginning of Feb. Mike Horton will,be there and will probably still have some Urac 185.

[psychmonky]

Keith,  

I may take you up on that if I go the Smooth On route. Right now I'm leaning toward unibond, simply because I don't deal with glass so I'm not sure I can justify the cost of smooth on.

Mac,

If its the first weekend in February I will not be able to attend. It's my 10th wedding anniversary and if I spend it at an archery festival it'll prolly be my last....lol.

Thank you all for all the advice and offers for help. I know without all the support from this site, I would have never even tried an experiment like this. Now lets see if I can't get it to actually work with some good Kennym Osage.

[macbow]

Scott, just bring the Bride and stay for the whole weekend.
Decent dinner at the banquet.
Got good friends that celebrate there,every year

[psychmonky]

NOW we're cookin'!!! A huge thanks to KennyM for this. Its been said before, but the man doesn't mess around.

 

Now All I have to do is wait for my new glue. In the mean time I can clean up the Ipe from the last glue up and lay out the profile on the backing.

[bowhntineverythingnh03743]

I just picked up some Unibond 800 which is the new Urac 185... cost about $30 for a quart of this stuff with both parts. I will let you know how that works but says it is the same thing as the urac...

Can't wait for it to come in and give it a shot!!

[psychmonky]

Yeah that's what I got too. The place I got it from also has different colors of hardener, so you could theoretically turn your glue line into a really thin accent stripe if you were so inclined.

[psychmonky]

Whew! It's been several days since I could work on it, but I finally got my unibond and got her all glued up. Now it's a waiting game. Ill keep y'all posted once I unclamp it and get it all cleaned up!


 

[bowhntineverythingnh03743]

I justed glued up a BBO fixer... what a difference unibond is. Did you find that it is setting up quicker than urac. I just got done and it was deffinatley setting up quicker IMO.

Love this unibond way better that that Weld whatever it is. I don't think I will ever change from Unibond and will actually be ordering a gallon of it.
