mpk Posted June 28, 2017 Share Posted June 28, 2017 Hi guys. I recently used CA and the results were not what I anticipated. What have you found the best glue for this purpose? Cheers. Link to comment Share on other sites More sharing options...
JMason5067 Posted June 28, 2017 Share Posted June 28, 2017 I would use superglue, or epoxy. mpk 1 Link to comment Share on other sites More sharing options...

LSP_Ron Posted June 28, 2017 Share Posted June 28, 2017 Not super glue, epoxy. Super Glue has zero give with metal mpk 1 Link to comment Share on other sites More sharing options...
ade rowlands Posted June 28, 2017 Share Posted June 28, 2017 I always use an Epoxy for that job. mpk 1 Link to comment Share on other sites More sharing options...
Hubert Boillot Posted June 28, 2017 Share Posted June 28, 2017 Agree with all the comments above. To add to what has been said, CA glue has excellent performance in tensile strength, and poor performance for any kind of shearing force. The best example is when you glue your fingers together. It will strongly resist the separation between the two fingers (tensile movement). In fact, the epithelial cells will give-in first. But if you apply any kind of lateral or torsional force to a CA glue joint, it will be very weak ... So for an undercarriage, a CA joint will very strongly resist if you pull off on the gear strut, longitudinally with the strut. But if you apply a bending pressure on the strut, the glue joint will probably snap ... This is why epoxy is better in some circumstances, or soldering when joining two brass parts at a right angle.

mpk Posted June 28, 2017 Author Share Posted June 28, 2017 Awesome again. Thanks guys. I've had epoxy in my drawer for over a year without using it. Tomorrow, it breaks out! CANicoll 1 Link to comment Share on other sites More sharing options...
Barry Posted June 28, 2017 Share Posted June 28, 2017 You should also try to have an "interference (tight) fit" between the gear mounting pin and the mounting hole in the plastic. Barry mpk 1 Link to comment Share on other sites More sharing options...
Bill_S Posted June 28, 2017 Share Posted June 28, 2017 JB Weld, Dale. Great stuff! mpk, Out2gtcha and CANicoll 3 Link to comment Share on other sites More sharing options...
mpk Posted June 28, 2017 Author Share Posted June 28, 2017 The fit is good. I'll try the epoxy, due to my having it. I checked out JB weld and will get some. Thanks again. Out2gtcha 1 Link to comment Share on other sites More sharing options...
Out2gtcha Posted June 28, 2017 Share Posted June 28, 2017 JB Weld, Dale. Great stuff! X2! HANDS DOWN vote for JB weld here. From my experience with it, you are more likely to break the gear itself than the JB Weld joint. Just make sure you have it where you want it, cause once that stuff cures, its there for good.

mpk Posted June 28, 2017 Author Share Posted June 28, 2017 Okay. JB Weld is currently in my eBay cart. BTW. Should I wait for it or just use epoxy in the meantime? Thank you. Link to comment Share on other sites More sharing options...
