I have been putting together a sig 4*60 arf and have run into so many problems with poor fitting parts. I followed the instructions to the letter and was fitting the vertical fin when disaster struck on the vertical fin there is a block of wood that is supposed to go over the wire joiner for the elevators. well i applied epoxy to all surfaces that were to be glued down and pushed the post on the fin into the hole it was supposed to go into this is where the problem started the block that is supposed to go over the joiner would not fit it seemed too long i tried and tried and in the end the epoxy cured too much and when i tried to get it out it snapped the post. I am devastated is there anything that can be done to get it out? if i can get it out i could order a new fin from sig. what would you do
