Cocobolo goblet

I hadn't turned a goblet in a while and with my current thin thing going on I thought i would revisit this fun project. Cocobolo, 4 3/8" tall, 1 3/8" max diameter. Stem is 3/32" dia. Finished with friction polish.

Great job, Chris. I wish i could use my skew so proficiently.

A lovely goblet, Chris, and deceptively small too. Until I read the dimensions, I though that it might be a foot or more tall. I like the small beads in the stem. So much to learn, so little time.

Thanks guys, I actually made a mistake in the description, which I corrected. The stem is 3/32" dia. not 3/16".

Oh, and by the by I did this with my 1/2" spindle gouge (40 degree grind), skews aren't my thing for thin items yet either. Wink

That is comforting to know that this can be done with a spindle gouge.

That's really a pretty, delicate goblet. And cocobolo is one of my favorite woods. It has a nice dense consistency that allows for a lot of detail and thin turning too. I'm curious how you steady it when the stem is so thin. I've been experimenting with using a piece of fairly dense foam rubber in the cup part of the goblet and using my live center in the foam. But I haven't turned that thin of a stem yet with that method.

You're going to hate me Curt, but I don't use a steady rest or similar method at all. All I did was stuff paper towel in the bowl portion before I started on the stem, run my 60 degree tail into the paper towel to center everything and then, here's the trick...use masking tape to "attach" the cup to the tailstock. Then, back the tailstock off a hair to apply just a pinch of tension to the tape. This helps to keep the stem from flexing from c-forces. Past that, I just use a very sharp gouge and a very light touch.

Nice job Chris. Your time spent with Stu is showing. Tell him I said hi.

Thanks Keith, with any luck I'll be boarding at Mammoth with Stu and some others in a few weeks. I'll pass on the hello.

I've pushed myself to learn skew use whenever I can, so that's what I'll use to finish the stems. I have also found that a regular, straight edged bench chisel works pretty well for me when doing the finishing cuts.
My bench chisels have a much thinner bevel and will take a finer edge than my skews so I use them to take off any imperfections I have left with other tools. I normally set the tool rest even with the top of the stem and hold the chisel with the bevel up, and at about a 45 degree angle to the stem. That gives me a flat contact surface to rub with so it doesn't dig in.
