It's early in the morning here, I've just come off of two 18 hour days, busy as can be, still I snuck down to the Dungeon to try this new toy.... er.... tool out!
From the time I opened the box to the first joint cut was 45 min, that includes swapping out the regular blade for my dado set.
The boards are just whatever size, so I did not bother messing with that, but the fingers fit together so nice!!
I'll play with this more, but all I can say is that I'm impressed!
Now I need to buy new dado set, the one I have leaves little ear like cuts. Maybe I'll get a box joint set or...?
