joining
I did mine not long ago and it worked out well after I finally figured out what layer went out / in.
I went to walmart and bought a bunch of putty knifes but only used a few.
If you do send pictures it should be obvious to us who have done it before.
Also once I joined it up the first time we have a progress inspection (we paid someone with experience to inspect what we are building) and they said the inner tabs need to be bent better to lay flatter for riveting. So I took it apart again. Once I had done it once it was very easy to join it again. And once it is correct the clecos join perfectly.
Don't loose heart, read the plan again, have a cup of coffee and you'll get it!
And please figure out how to post pictures, it would make things much easier.
Have fun, Larry
