Thread: Self isolation gun projects

Now just moving right along there I have converted my long suffering lathe to a rifling machine. Hand cutting six groves .010" thou deep to give at bore size of .470" and a rifling twist of 1-48", the standed for muzzle loaders. Here you can see my improved set up, well sort of. There`s no such thing as" Can't do it".

, Cutter head pulled through .
, The sine bar that drives the rifling head at the back of the lathe, low down for slow twist.
