Milling & Mortises

While the walnut rested after it's initial milling, I got to spend time at my bench, cutting & fitting the mortise & tenon joints for the doors. They're through mortises & with wedged tenons, doubled up for even more strength. This meant deep mortises 3 1/4". Cut with an end-mill & sliding table on the drill press. Time to pull the trigger on a slot mortising machine. With the tenons being so long, I roughed them out on the bandsaw first, then used the new 184 delta tenon jog to dial them in (really like the rapid fire macro adjust, & micro-adjust to creep up on it, nice jig), then did the final fitting with handtools. A card scraper works well to dial in the radius on the tenons, after initial shaping with a chisel or file.
Here's the Walnut all milled up to final thickness. moving these 8/4, 10 footers between machines takes some time. Setting up co-planer in-feed & out-feed work support stands becomes a Zen art form. How about a support stand with rack & pinion adjustment, & how about some levelling feet. I see Lee Valley has stands that look pretty good. These planks are tense. beautiful grain, but seriously tense. Dealing with such long lengths must be partly to blame, but maybe also because it's kiln dried, so probably drier on the inside than outside. But they just want to bow like madmen after a pass, and resawing really pissed them off.
