Segmented Turning


What do you think of this? 

This is an example of segmented wood turning. 

You start off with a set of 9 sticks, 5 of one wood type and 4 of another. They must be made all the same size. In this goblet, they are 11/16” square. Five of them are Red Gum wood and 4 are Hard Rock Maple. This makes up the inner core.  You alternate the wood types in the core so that your colour of choice is in the center which then makes the stem of the goblet.

This glue up turns out to be square, or at least it had better be!!! These are then surrounded with the next layer which in this case is Cherry.

You then mark the center being very pick, you have to be dead center on the center core piece or the whole thing will be off center and is a total wast of time. Then comes mounting this in the lathe.

Then go ahead and turn a goblet. I always just round the whole thing first, then true up the ends and mount it in my 4 jaw chuck. If you are turning a long goblet, use a steady so that the tail stock can be backed off and used to bore a center hole so you can set up the depth of the upper part of the goblet. Use as many different sizes as you like to get the size and shape you are looking for. Complete the inner shape, sand and finish it. Because you are cutting all end grain during the hollowing of the bowl of the goblet, you need to have a set of tools that will cut end grain and not tear it. You also need a tool rest that will let you get inside the goblet. 

Once the inside is done and the finish has dried, you can remove the steady and put the tail stock back to work. You may need to make a piece that fits in the goblet for your tail stock live center. Then you can turn the outside of the goblet, turning the small stem last. 

Then part off the base from the part held by your chuck only after you have done all your sanding and finishing.

If you are planing to use this goblet for your favorite beverage, you better make sure you finish it with a product that is impervious to it. I use one of the new rub on Polyurethanes. Easy to put on and looks good. Once it’s dry it is food safe.

Good Luck.
