Pacer hinge glue
 
Hi, does anyone know if you can use pacer hinge glue for CA hinges. I am very allergic to CA, but like the hinges.

They say most hinges but I've tried on CA hinges.

if you are switching glue....then switch hinges....

The GP or Dubro nylon flat pinned hinges are much more reliable.....

If you know anyone who is using the glue, ask them if they'll let you borrow the bottle for a test. It won't take but a tiny bit to try.

And you'll both learn from it.

In our hobby, the best way to find out something is to try it yourself. And some things like this, are very easy to test.

When I first saw the stuff, I knew I could use it for something if I didn't like the way it worked on pinned hinges like Dubros and Kletts. So I bought a bottle and setup a test. The test took 15minutes one night. I simply installed a couple of hinges into scrap balsa. I noticed right away how very much easier it was to use than epoxy. MUCH easier, and almost foolproof. The next morning I tried to pull the hinges out. Impossible. I could tear the balsa away, but it left a layer of balsa glued to the hinges.

Get some and try it. And then let us know. You'll go from a beginner to and expert overnight. At least an expert in the answer to this question.

You know. I think I'll go to the shop and setup a test. Get back to you tomorrow.... if I remember tomorrow that this thread is still here.

I don't know about 'more reliable'.

I use CA hinges, have been using them, and have had only one problem, on my Tiger 60 way back when. I didn't know that I should not have added CA again after the initial application. I ended up re-hinging the plane, with CA hinges, and still fly it.

My Excelleron 90, a pattern plane, Venus II, also a pattern plane, both use the CA hinges without any sort of problems at all. They hold, they function, and they are compltely reliable, as far as I am concerned. I used CA hinges on my Tiger 120 with no problems. I also used them on my Seagull Super Star ailerons, and when I get ready to finish up the tail feathers, will use them on the elevator and rudder.

It all comes down to a matter of what you use and like. I happen to use CA hinges and like them, so I will stick with them. I tried them on scrap as DA Rock did with his setup, and when I pulled them apart, with some difficulty, I might add, a chunk of balsa came out with the hinge.

I don't make recommendations because, as the saying goes, 'different strokes for different folks'. If someone asks, I will tell them.

As far as use of the Pacer glue is concerned, well, DA Rock has a great point. Try it using CA hinges on scrap and see if it works. If it does, then let us know.

DS.

OK, test is setup.

See you tomorrow. Time now to go fly.

RE: Pacer hinge glue
 
BTW, what I noticed about the installation of the CA hinges with this glue might be overlooked by some beginners.

The slot needed is thin, very narrow. And you're probably going to want to use the slots already cut into your ARF. The hinge glue is fairly thick stuff. I noticed that when I started using it with the Dubros. So I've thinned mine a bit. It still works great on the plastic hinges when thinned. I know that because I tested the thinned stuff also.

So when I did this test, I had to hold the glue nozzle firmly against the slot and squeeze for awhile. And I then slid a straight pin down into the slot and wiped the glue down into the hole. Then I coated the CA hinge. When I slid in the first one, the glue had a tendency to grip. That's not surprising. But I'd keep that in mind and be prepared when doing this on an almost finished airplane. On the second test hinge, after I'd filled the slot and coated the hinge, I dipped the coated side into a small cup of water to make it easier to slide into the slot. It went without a grab. I did 4 hinges into the scrap. Didn't do the other half of the job because I intend to grip the hinge sticking out with pliers.

time to go fly....... good sky, good wind, just a bit warm........ gonna be an EXCELLENT day! But then, any day flying is an excellent day....... see ya'

OK folks--I have two samples that I am trying. One is see if it will wick in like CA and the other was to put some on the CA hinge before installing. Let you know in a couple of hours.

Yeah, I'm retired and fly more days than not. Wasn't going today actually, but got a couple of students who're hot to go.

I'll try hard to enjoy it....... grin............. And I always think about how nice it is for me, and not for them what kain't be out there so try a little for them.

Hey DaRock--I am also retired and I just got back from flying my Aspire. I am a better builder than flyer. Every one talks about learn on the Sims--I have one but the missing ingredient is the anxiety level--none with the Sims, lots with the real thing.

RE: Pacer hinge glue
 
Installing them one at a time doesn't appear to be presenting any difficulties yet. How about when you attempt to do the "second side" and have to do 4 at a time? Will the CA hinges still insert easily into the hinge glue that may already be starting to "tack up"?

May want to simulate that for a test also da Rock.

Bruce--you always have to make it hard. guess I will build a aileron sample and see.

better to screw up a sample than a plane.[:@]

you got that right. I always appreciate your input, seems to be right-on

Glue tacking up over time? Or we could say the "pot life" could be too short. Truth is, I don't think it'll be a problem but for a reason. Read on.....

Using the stuff, I got the impression that would not be a problem. But I'm waiting for goirish's test results. Looks like we got some good teamwork working this problem.

When I looked at the problem first off, it's obvious the glue isn't going to wick like CA wicks. So the hinges need to have a prep coating to have any chance glue will be on them when they push the glue already in the slot further down in the slot. And I noticed awhile back that the glue seems to work just as good if it's cut somewhat with water. I've got a ready source of water in the shop. I figure we need to prep the hinge flat for the reason mentioned and also to squeeze glue into the slot to get glue penetration in the "flats area" inside the slot.

When I setup the test this morning, I figured I'd try one hinge with "wet" glue. So I did a couple with unthinned as the basic test. And then I took a third one that'd been precoated with the others and dipped the sucker into a little cup that just happened to be sitting there. (It was brush cleaning water. I'm painting the scale pilot for my H9 Corsair.) It appeared to give the preglued flat a slickness and that hinge slipped right into the slot. I've seen that glue bond like tig weld when it was thinned, so I'm not apprehensive a bit about how the test is going to come out tomorrow. But tests have proven me wrong before. It's why I do them.

But it's kewl when an experienced modeler throws in some insightful thoughts............. Like this: Will the CA hinges still insert easily into the hinge glue that may already be starting to "tack up"?

From what I've seen, the glue in the slot isn't going to be the problem. It doesn't see much air and doesn't seem to have time to get tacky. But the "tacky" problem does rear it's ugly head on the group of flats that have to be prepped before you stick that aileron on. And I'd think my dipping (or dripping or whatever works) helps that problem. I think.

Good observation, Bruce. Experience shows, don't it.

Hi, I did a test with the glue by seeing if it would wick into the hinge slot with the hinge already inserted--it would not. Then I put a thin layer of glue on the hinge and put it in the slot--after approx. 45 min. was unable to pull the hinge out. Then the next test was to do 3 hinges in a sample aileron--I wet the hinge first and then applied glue to the hinges--was able to put all three in both sides with ease. Flexed the aileron to line up the hinges and waited approx. 1 hr. was unable to pull apart. This maybe my answer to using CA hinges without using CA. If anyone else tries a test please post it. Thanks

You learn to think of things like this when you accidentally use the wrong speed epoxy on a project and end up cutting new parts. You MUST plan ahead.

Now, tomorrow, tear the test wood up and see for sure how far the hinge was glued. You'll learn a bit more about the techniques you're pioneering. I planned to do that in the morning with my test.

BTW, we used to do this destructive testing all the time back when we built everything. Reason was to find out what we'd done right and what'd been done wrong. And whenever we wrecked one that wasn't going to be rebuilt, it'd be autopsied. Hinges and their slots cut open, glue joints pried apart, etc. Best way to find out how well our techniques work.

Will do, that sounds like a good idea. I know that I can't pull the hinge out--tried with a pair of pliers.
