Continuing somewhat destructive de-construction; removed top sheeting of fuse from LE of wing aft. Used punch to remove hatch latch. Tried heat on sheeting but ended up using brute force, a planer, and aggressive sanding tools. Looking to deepen fuselage by an inch and a half or so to make it TLAR. Wood is strange - very brittle - think they call this Luan.
Also began pulling off ailerons and uncovering wing panel.
