Man, the windlass has been an adventure, let me tell you. I needed to cut an appropriate sized piece from rougher cuts. So I squared the piece I had, then I off an appropriate length and cut that piece down to the 3/8" square that I needed. And this is where I ran into trouble.
My first attempt was really close, within tens of a mm, but I thought I have enough wood let's try again and see if I can get it perfect. Well somehow I ended up burning out the next piece of wood and ruining the blade. Had to order a new one, still not really sure what went wrong.
So I took my first and only cut and went to work. First, make it an octagon.
I thought maybe I could use the table saw to cut off the corners and make it a nice clean cut but after angling the blade I realized the piece was too small to run through it without making a custom sled for it. So I hand carved.
Combination of using my single sided razors and sanding on a glass base to get each side as flat as possible.
Originally I was going to cut the three sections out by using the lathe. Didn't work out.
Instead, and ironically I don't have any photos, I used the mill. Turns out the square bit I have is the perfect width for what I was going for. I tried using the razor here first but I just couldn't get it straight enough. So I cut out 1/16" deep cuts in all three locations.
Tedious work having to remove the piece, rotate it, clamp it back down, line it up and cut 24 times, but the result worked nicely. At this point I started the taper and rounded the end cuts.
After a while it took shape. I had to carve the teeth into the middle cut, that took some serious cleaning. You'll notice it's a bit long on the ends, it'll need to shortened on the disk sander to be the correct length. I originally left extra so I could use the lathe without damaging the main piece.
Lots of sanding, cutting, and shaping later here is my first take on a windlass minus the square peg holes I need to drill in next.
