There’s more to mortises than the boring machine, as enticing as that device is, it’s only the start. I wait until there’s several joints laid out, then bore all of them…then tuck the machine away & go on from there.
Here’s one of the through-mortises that’s all bored, three 2″ diameter holes:
Then it’s chisel work. This is actually a different mortise, but the principal is the same. Here I’m chopping the end grain.
And here paring the side walls/cheeks of the mortise.
I went to pick up my 2″chisel the other day, and there’s a ladybug crawling around. In January?
This mortise is chopped. Now the timber needs to be reduced to 5 3/4″ at the joint. It’s how we compensate for the various sizes of 6x6s in the frame.
First, saw down to the scribed lines,
then knock out the waste with the chisels,
then pare it flat.
then cut a bevel along the bottom end of the mortise, where a corresponding one on the tenoned piece meets it.
