Good Day All,
This week's heat wave has my loft shop over 100F and quite sticky.
I did find some early morning shoptime, and experimented with a new-to-me 4pc leg. (link)

My sample worked out fine, but proved fussy and time consuming. I am not
sure which approach I will use when I start my chair legs early tomorrow morning.(?)
I find Gary's legs to be very attractive and doable. I have until morning to figure myself out.
Nathan, I dug around in my shop and found my first try at through mortises
in white oak. I suffered nasty scalloping, as shown here. (tried to embed pics here, but they are at bottom)
I found that sharpening of both the hollow chisel and auger bit is crucial.
But, for me, the solution was to NOT leave a gap to drop the bit relative to chisel tip.
That advice is everywhere, but proved to harm, not help my efforts. If the bit extends too far,
it can engage the stock too soon... and also be horsed around from side to side.
Merely seating the auger bit and chisel fully, solved it for me. (!?)
I was honing the outside chisel flats on my waterstones, but that is wet
and messy. I now do the same with folding diamond hones from LV,
in 600x and 1200x. Quick, dry and tidy---but bonus, I can do it while the chisel is mounted in the mortiser. (link to LV diamond hone)

Inside the chisel I tune up with the fine and coarse cones as shown.
GZ's drillpress rig looks slick. I get by with softwood faces on vise to hold
her steady, and cones slowly in a VSR drill. Back to diamond to remove wire edge.
I use the auger file to deburr chip ejection port. It only cuts either on face, or edge---but not both at once, so no collateral damage!
The auger I also file the cutting flute, the scoring bevel and clean the points. I learned to hand sharpen twist drills on bench grinder in machine
shop as a kid. I am timid to power grind the auger, and find the hand file
works fine and not too aggressively. (your mileage may vary)
I am gonna try to get into my shop before my busy day, to beat the heat and get some bonus time to start building my chair.
In the original invitation post I had projected a July start.
If I can get something cooking in some very early mornings, I should be able to have my legs done just before July ends. (sneaking under the wire)
I will post any progress,
Walt
