Next I am going to set the barrel back where it should be. Then scribe lines down the entire barrel to show its profile.
Pretty basic now.. I stab in just inside the lines and start removing wood with a gouge.
Next I start removing wood from the octagon area using chisels..
Now this is where my little 90 degree comes in to check the depth of the cuts. Once the sides touch (where I have the profile of the barrel cut in) along with the point (touching the bottom of the channel) the barrel is roughly 1/2 way inlet.
A bit more to go down.
There…
Works on the round barrel channel too.
