Sweet - so I've had a sepcial(ish) PH-LAM from the start. I had no idea. Thank you!
Unless it has the logos on the wings...no, sorry. You actually had the most-common version. The one you're trying to repair is somewhat more uncommon.
Now... anyone else have good close up pics of the first run PH-LAM to help me determine best way to file these two halves back together?
Remove the damaged parts, file them flat, hopefully it's just the joints. Drill holes for pinning, pin the parts and then use green stuff or some other putty to go over the pinning and sculpt as jointing.
