I was lazy yesterday.Did a lot of other things that were productive, but never went near the plane.


Today I got off my lazy butt and got busy on the parallelogram jig. I SHOULD HAVE STAYED LAZY!!!!!!!!


I totally screwed it up. I have one parallelogram built. IT AIN'T RIGHT!!!!!! The wing support arms are off about 3/32 front to back.


I made a jig to drill all the holes in exactly the same locations. I used a 1/4 bolt as an indexing pin for each hole. I have checked and I have holes that do not perfectly aligned and found one the was a full 1/8" off.


The jig I made has a fence and a indexing pin hole. I checked and trued my drill press. My jig is very securely clamped to the drill press table. I marked the working face of each piece and also the front of each piece.


But I ended up spending hours turn 3/4" square steel stock into garbage.


I do not know where I screwed up. I did not rush this. I spent a lot of time brainstorming it out.


I have gone over my steps and set up, and just don't understand how I could have had holes out off alignment with each other.


I am so p***ed off.


I will post 1 or 2 pics here, but I think I need to open a new thread in the Questions and Answers section. maybe someone can set me straight.
