Hello Sung.
Are you still looking for taper bars for your lathe?.I made some they are at anodize and should be done soon,they are mounted on a 4 station indexing mount.You get 5 bars/patterns all patterns have the profile milled on them the finish patterns have room for adjusting the pattern.
It will come with shaft rougher,handle rougher,shaft finish,handle finish,and point mill angle, to use mill pattern you have to remove the handle rougher pattern.
I will have pictures of a set mounted on a lathe as soon as I reassemble it in a week or so.
Cost $500.+ shipping
