made some headway as well as some serious mistakes today.
1. finished the mortises/notches for shelves of bookcase
2. finished through tenons
3. started mortise for tenon in top of bookcase.
ok, fine, but:
when going top-down on the mortise with my chisels, i blew through the bottom side and got some serious tearout on all edges. i thought that by clamping the board down on a sacrificial piece of ply i would be ok, evidently not at all! so that wil require a serious bit of care and touch up, possibly with wood filler/finish+sawdust. CRAP.
also CRAP is that when on my way to finishing the mortise i DROPPED both the 1/2 and 1” chisels i was using and they hit the concrete and got some nice gouges in the blades. so that was extremely discouraging. the 1/2” was worse, so i figured I was done for the day and to punish myself i got down to rehoning it immediately. took a while even on the 60grit paper – the gouge was in a corner, where it could do the most damage, and about 0.5mm into the shank. The 1” chisel got dinged much less worse, that wont need to be completely reground, i think.
on the plus side, i did get good experience using the chisel on those notch mortises.
always approach a through mortise from both sides.
never drop your chisel. definitely dont do it twice in one day. hah.
