Sasquatch thesis on Billiards https://pipesmokersforum.com/community/threads/a-dead-ordinary-billiard.10910/
I copied the first post. I don't think we can move the whole thread over.
I posted this series of pictures elsewhere as an attempt to help newer carvers understand what a billiard needs to look like, some of the standard things to look for.
A billiard has some mathematical relations that make it look "right". You still need to make a nice looking pipe on top of this but understanding the basic proportions of the pipe helps.
Basically, relating only to itself, a billiard is a pipe with a fairly "tight" bowl, approximately 4 times as high as the shank is thick. The height of the bowl measured from the shank should be about the same as the length of the shank, measured from the bowl. The total length of the stummel, the bowl diameter + the shank should be equal to the stem length.
So.... we mark out a block. The drilling is going to be at about 3 degrees beyond 90 - if you build a pipe at 90 degrees it looks awful. So we cant the bowl forward a bit. In my case, I just literally cut the block so that the front and back ends are at 3 degrees - whenever I seat it in a vise or a chuck, the angle is there.
In the chuck, starting to have a shape:
Now I have bevelled the inside of the rim - this makes the pipe look lighter up front. Stem material is roughly shaped and the tenon is cut to fit.
At this stage, the new billiard-maker will stop, fearing he hits the chamber or something - keep going! This is not a billiard yet! It's a big ugly lumpy fist thing!
Tons of material has come off the bottom "chin" - now it looks a bit like a billiard. Notice that the bowl does NOT dip below the line of the shank. This is what we big time famous pipe makers call a "nono".
Et Voila!

Et Voila!
So at the end of the day, we want to see a nice tight joint between the bowl and the shank, we want the shank to taper just a little, the stem to taper more than that. The bowl is softly curved but not "fat".
Easy as pie after about.... #25 or so.
