Cool Need to apply epoxy precisely?

Squirt both parts into the corner of a sandwich baggie and twist it up into the corner (like a cake frosting bag).

Then roll it around between your fingers to mix thoroughly.

Clip the tiniest part of the corner off and squirt it into the smallest of areas with precision.

No more mess, none on your hands; no more pieces of cardboard and toothpicks!

Works for epoxy, JB Weld and Bondo.

That's cool, but I like syringes.

That's pretty much the same system we use at work, we roll printer paper into cones and apply epoxy the same as a baker decorates a cake. Not sure I would mix in the bag though. You have to be careful with the syringes, the ones with the rubber plunger contain oil that will contaminate the epoxy.

Go and buy a cake decorating kit and it comes with tips and all you will need for fillets and small tight areas.

How do you clean the cake decorating kit after use? Or do you have to buy a new one each time?

Been using the Monoject 412 for precision application of epoxy and Gorilla glue for many years now, they are about $.050 cents each anyplace on line and they clean up with acetone and can be reused over and over, These work great for injecting hinge points as well.

+ 2 on the syringes .. Thats what I use for both Epoxy and white glue..The bags are an excellent idea and I like the cake kit because sometimes we need a larger amount..We should be able to use all the ideas at one time or another.. I use EPO GRIP Epoxy almost exclusively because of the Vaseline like consistency.. It is so easy to work with . It it the best stuff with hinges .. It does take a while to set..but it is strong ..I am surprised more hobby shops don't carry it ..

Me too, as well as syringes from bird stores that are used for feeding chicks. If using white glue, you can seal the tip with a small piece of masking tape until the next usage.

I like the original post idea though, as cleaning with acetone can get messy. Throwing away a bag is a lot neater and faster.

Syringes are 2/$3.15 from West System Epoxy and you can re-use them a dozen times or more.. Just filled and drilled stantion base bolt holes on my sailboat last weekend with one.

I heard that epoxy cleans up with vinegar. I have not tried it yet myself. But vinegar at $3.50 a gallon is a lot better than isopropyl alcohol or acetone at $15 per gallon. I have not cleaned my used syringes because the cost of the alcohol or acetone is more valuable than the syringe.

I find that i am able to reuse alcohol or acetone so that it is not that expensive to clean a syringe . I usually use alcohol

The epoxy just peels off the syringes if you let it dry. Straighten a paperclip or use a pushrod to force the plug of dried epoxy out of the tip.

You have got to be kidding ? I am going to have to try that.. I always assumed it would be stuck forever on the ones I forgot to clean . ..What do you do , pull the plunger after you are done ? I remember trying to pull the plunger out on one I forgot and the little rubber end stayed stuck fast inside .. I never though about pushing it out from the end . I think there was still about 1/2" of epoxy left inside too.. I guess it would be best too squirt it all out and pull the plunger ,then let it dry .. I still think it would be easier to clean it with a little alcohol .. but keeping an open mind is always a good thing ..I will try your way Charlie ..

Push the plunger all the way forward and let it dry - then pull the plunger out just 1/8". Push a wire (straightened paper clip works) in to work the plug of epoxy in the tip loose. Then pull the plunger the rest of the way out.

Sometimes the suction alone pulls the tip plug of dried epoxy out. Sometimes you have to push it. Peel as much epoxy off as possible manually and use 91% alcouol to clean the rest off the plunger head and other places as needed. If you let the epoxy dry it peels easly off poly-plastics.

I just mix epoxy on whatever is convenient: kitchen table, fine Royal Dalton china, antique dresser, etc. then use masking tape to delineate where epoxy goes. Once it sets up a little I just peel the masking tape away. Your models' perfect glue joints will reflect the beauty and execution of the exquisite craftsmanship you possess!
