Tips and Tricks
Work Holding, Drive Centers By Leon Olson
Today there are a lot of drive center options. Typically, lathes come with a four prong drive center. We had the same four-prong drive center fifty years ago. Now the choice of drive centers depends on what you want to do.
There are woods that are hard enough that pressure from the tailstock is not enough to drive the prongs of a four prong drive center into the wood well enough to hold. If you use a four-prong drive center without using a mallet to drive it in, there is a chance it will fly off the lathe.
There are a number of types of drive centers. Each with their advantages and disadvantages. I no longer use the four-prong drive center except to check the alignment of the headstock with the tailstock. Michael Hosaluk likes the Oneway Safe Driver or cup drive because he does a lot of off center turning. If he has a catch, the wood stops and the drive just spins against the wood. The center is spring loaded. Alan Lacer likes the Safe Driver as well but he wants a little more traction so he grinds the three notches in the cup edge.
I have seen professional woodturners use two prong drives because they can rotate the drive until they get both prongs imbedded into the uneven surface.
Barbara Dill uses the small four prong drive for her smaller multi axis turnings because she can use less tailstock pressure. She also drives both the drive and the live center in for each center line she is using before she does any off center turning. Once she has started turning, there is not enough strength in the remaining wood to drive them in.
Some of the aftermarket four-prong drives are easier to imbed in the wood.
Sorby tools came up with the Steb drive which is my favorite. They come in multiple sizes and are used on both drive centers and live centers. The center point is spring loaded. At this point most manufacturers have their own version of the Steb drives for a lot less money. There are occasions when you have a catch and the drive keeps spinning and cuts like a saw. You just clean out the chips and start again.
When your blank is heavy enough, none of the drive centers shown above will have the grip to drive the blank. Your choice will be either a faceplate with screws which requires that the surface be flat and perpendicular to the spindle or you can use an Elio drive from the Woodturning Tool Store. https://woodturningtoolstore.com
I am certain there are many options and you could even make your own. Necessity is the mother of invention (or perhaps desperation).
