Any tips on freeing up the hinge joints (I'm using Dubro hinges). The control surfaces are a little sticky, not as free as I'd like. I was thinking putting a drop of denatured alchol and working it, but would this degrade the glue? Any suggestions would be appreciated. BTW I put vaseline on the hinge before installing.
Thanks,
Pat

I always check that's is straight, also the slots were originally CA slots which I increased the size for Dubro. I'm thinking that maybe where the barrel part of the hinge was rubbing against the wood maybe some glue got in there and increased the resistance. When I install them I give a little more throw than recommended by the manufacturer to reduce the hinge gap, but when I got done it seems that the throws are reduced alittle (but still within manufactures specs) I'd like them to be where I set them and be very free throwing.
Thanks,
Pat

Status: online 		Are these the flat hinges? What glue did you use? I've had to cut flat hinges before and used the slot machine (very carefully) to cut a new slot in the same place. If you used epoxy, a modified razor blade or square tip exacto blade in a solder iron would loosen epoxy up. Keeping in mind you have to be real careful doing this or you ruin the existing slot. In that case, you glue a plug in and re-slot it. If round hinge points (I have mostly robart and gp), I use a dremel to route them out and re-glue using gorilla glue.

Status: offline 		I have used the solvents & tried to pick at the glue to free them up. I have had little success freeing up hinges in general.  I have had them loosen with use. Generally I have failed to align the hinges properly in all axis.  One binds against another as they are moved.  Prehaps just one is the offending character & can be replaced?

Canopy glue is the best glue & most forgiving glue to put them in with.
