The issue is the amount of force and the travel involved to make 9" inserts. As of right now, my machine maxes out at 5.5".
I could create .670, .678 and .685 inserts fairly rapidly, as that is material ID I stock. All other sizes are custom created.
so are you stretching them open with sime sort of hydraulic ram? Or i saw tubas being created on how stuffs made and they were using hydraulic fluid to force ball bearings through a tube to get the correct id.
