Goblet

 
Close up of small knot after scraping cut

The area after the skew scraping cut. No more torn grain. Adapt your techniques to what the wood gives you instead of trying to make the wood do what you want. The wood is not going to change its characteristics but you can change your techniques.

Sanding cup outside

This is a fresh piece of wood and will warp slightly as it is hollowed so sand and finish the outside now while it is still running true. Wet wood will clog sandpaper quickly but as the surface dries it will clog less. Try not to generate a lot of heat while sanding or the wood surface may develop cracks.

Wet sanding will work also and help with the clogging of the sandpaper.

Outside of cup finished

The cups outside finished and ready for hollowing. The finish will help slow some of the moisture loss while hollowing and may help with warping to some degree.

Select a finish that you like to use. I do not turn these goblets for actual drinking so I do not use a finish intended for that purpose. There are plastic coatings and other finishes that might withstand having a liquid setting in them for a long time if you want a drinking goblet.

Setting the depth to be drilled

Setting the internal depth of the cup with a simple wooden depth gauge. I set my depth gauge to slightly less than where I think the finished bottom will be. Once I have hollowed and removed more of the waste wood from the bottom area of the cup, I will be able to match the inside to it. Better to stop a little short when drilling than to go to deep.

Marking depth on drill bit

Using the depth gauge setting to transfer the measurement to the drill. I use duct tape around the drill as the marker for the depth. I do not want to buy stop collars for all the different size drill bits I may use so tape is a cheap alternative.

Drilling a depth hole in cup

Drilling the depth hole in the cup. End grain is had to cut straight into so this hole will give a starting hole for hollowing.

Spindle gouge hollowing with the grain

This is an end grain oriented piece so the most efficient way to cut the wood fibers is to go into the center and cut out to the rim. The tip of the spindle gouge goes into the center of the wood and is pulled or pivoted out toward the cup rim.

Hollowing with spindle gouge against the grain

Hard woods and sharp tools will allow a cut against the grain that leaves a good surface. Try to see what the wood will allow while you are in the waste area of the wood.

I have the lathe rotation reversed so I can see the cut as it progress and I am not leaning over the lathe bed so far this way.
