The first lathe machine was developed by the Egyptians and was then called the two-person lathe machine. There were other modifications of the lathe machine that were developed in different time periods. No matter how the lathe machine may have been modified, the basic parts are still similar and form the integral components of the machine.
A stone projectile point is made by a sustained effort of chipping and flaking stone called flint knapping. Flintknappers work a raw piece of stone into its shape by hitting it with another stone (called percussion flaking) and/or using a stone or deer antler and soft pressure (pressure flaking) to get the final product to just the right shape ...

Now it's time to set and glue the seam. We use a pair of seam setters called Gorilla Grips from Monument Toolworks. We pull the seam together and then separate it just a tiny bit before leveling (leveling with the pieces touching can chip out the seam). Then we use the cams to level the two pieces.
