Epoxy Gluing Techniques
 

Does anyone know of a neat clean, way of gluing joints with Epoxy that doesn't leave a mess to clean up
and still give srong joints?

I use a cotton swab or a pointed skrew stick on small joints.  Helps control the amount applied.  I also use 30 minute cure so it is a little thicker.

Use a brush if coating the engine area and thin it some.

Try applying the glue with a pocket screw driver to control the amount needed for small joints and if any clean up is needed, use a small square of paper towel and rubbing alch to clean the area~ I also add ground up fiberglass to the mis most of the time... (Great planes makes the fiberglass) Good luck!

If joining large parts, like wings, you can put masking tape around the area you don't want epoxy on. After joining wings and wiping the joint with alcohol on paper towel, peel off the tape.

I have also put epoxy into a syringe for application, but it is only good once. You can get a "needle" tip that is rounded and dull (I think it is for injecting meds into I.V. tubes). This tip has a larger I.D. that will pass thick glues quite well.

Once I put mixed epoxy into a sandwich baggie and cut off one corner. Squeeze the glue out like a cake decorator does with frosting. It was rather messy getting it into the baggie, but still worked OK.

As stated by another post, use slow set (30 or 45 min) to give you some working time. ;)

For most applications, I just use popsickle sticks to mix and apply. If I need a smaller applicator, I just cut a piece of scrap wood to the size I need.

I use a pipe cleaner. It's more durable than a Q-tip and spreads the epoxy as well as a brush. After spreading the epoxy, I just cut off the used piece with a wire cutter and have the remaining portion available for the next application. One pipe cleaner will last for several applications.

Em, not nice to have the same thread in 2 different forums ...

When using epoxy to bond two pieces (as compared to fuel proofing a surface) I make sure that I have at the ready: paper towels busted into individual sheets, a jug of alcohol with the top off, painter's blue tape, wax paper, stir stick, epoxy and appropriate jigs to hold the pieces in place while the epoxy sets up.

I mix my epoxy on a piece of wax paper (rather than a cup - easy to toss) with a popsicle stick.
The paper towel w/ alcohol does a great job cleaning up waste or oops and cleaning up tools before the epoxy has a chance to set up.
I tend NOT the use tape as a boundary as it will result in a hard edge that will be a real B to sand flush but I will use it to keep things straight - like a jig or clamp (thinking about holding fins square, control surfaces straight while gluing hinges, etc.).

Next time - pick a specific forum for a thread.

thank you all for your responses Huck i tried the Q-tips worked real well especially pushing glue in cracks
I never thought of pipe cleaners and reusing them good idea
and completely forgot about alcohol and rag, all these respones will help me become better in the future
again thanks to all the advise you've posted
I believe if you don't know how, just ask someone has a way out there
