Hi guys

I have a hobby mat mini lathe im pretty new to using it.

Im trying to bore a nice smooth hole which is fairly deep but i cannot get a smooth finish.

The outside finish is really nice. if i reduce the length of the boring bar i.e bringing it closer to the tool post the finish improves. Ill upload some images later you can see what i mean.

My question is really if i am using the correct type of boring bar or if there is a way easier way of getting the nice smooth interior finish.
