Can anyone let me know the best way or tool to use for putting a tapered bore in a piece of cherry. It is a 2″ sq. block about 4″ long. The smal dia. is .615 and the large is .688. I currently chuck the block up in a 4 jaw chuck and put a 9/16″ drill bit in my jcaobs chuck and feed it with the tail stock. This works great, then I have a spiral reamer with a 1 degree taper that I put into the jacobs chuck and open the bore up to the above dimensions. This however leaves spiral groves in the bore. I need a smooth and acurate bore. I have changed speeds on my lathe from 500rpm all the way up to 2850 rpm. This is the way I would do it with steel but it does not seem to work in wood. Iam using a reemer designed for steel. Any suggestion would be welcome. Thank You
