The Porper Cocobolo cups are truly excellent. He also made some in Alder, which is a very popular wood for electric guitar bodies.

One of the problems with wooden cups is overcoming wood's natural tendency to change its shape when new surfaces are exposed to the atmosphere. Joe's solution for this was to use two pieces of wood that were assembled in such a way that the grain basically counteracted its own tendency to move.

I have to say, though, that Angelo got it right on these first cups right off the bat. That first set in cocobolo and ebony has been here for a few weeks. These are rather large cups. They could be difficult to handle except for the way the rings are installed. The rings are at just the right point to make picking up the cups and putting them down a matter of ease instead of a task. The first time I picked them up at NEMCA last year, I could feel that they would work very well.

They do.

These feathered cups have given me some really odd ideas. I believe Angelo is approaching cup creation and design from a new point of view. This is quite refreshing.

I didn't see Keith's post about the two-piece Porper cups when I posted that information.

I'm not a skilled wood turner (nor did I ever play one on television!); however, I do have a wood lathe in my garage, and I have been known to make rather large pieces of wood into small pieces of wood surrounded by immense quantities of sawdust. If you think that sawing through a board makes a mess, try turning a bowl or a cup.

One of the big considerations when turning something from a piece of wood is how the wood is going to react once the new surfaces are exposed to the atmosphere. With some woods, you may have to finish a piece over a period of weeks, just to make sure that the wood has a chance to recover.

One of my alternate vocations is as a banjo player and set-up man. About 20 years ago, divers began recovering logs from the bottom of the Great Lakes, where they had been resting for a couple of centuries -- the result of the large flotillas of logs that were floated down the river from the old forests in Canada and the Northern US. This wood had aged anaerobically, producing a type of wood that was radically different from the wood that came from the same type of wood that had aged in the actual atmosphere. The wood, itself, was not waterlogged. The lake water only penetrated an inch or so into the logs, which were usually several feet in diameter.

The tonal qualities of this wood were amazing. Banjo companies started making the wooden rims that form the bodies of the banjos from this old growth "submerged" wood. Two basic methods were used. The rims, themselves are turned from a piece of wood that is basically a circle slightly over 11 inches OD and about 9 3/8 inches ID. This circle can either be laminated from three pieces of wood that are a little over 1/4 inch thick, bent under steam pressure, or it can be made from blocks of wood. I have some of these rims on instruments in my collection.

The rims that were made from the wooden blocks generally warped less and remained truer than the ones that were laminated, which tended to become oval. The biggest problem was that if the wood was not aged correctly over a period of approximately two years, it could collapse if subjected to sudden extreme dryness. You can't force this wood to dry.

If you have ever gone to a market where they sold pecan wood bowls, you will probably recall seeing bowls that were made of wood that was about a half inch thick, but they were oval. They weren't oval when they were turned. This happened after they had aged a few weeks.

This two-piece construction allows the wood to expand and contract proportionately, so the cups do not become oval over time.

Just visited the Joe Porper web site and got a closer look at the cups. One thing I noticed about each cup is that they are not turned from a single piece of wood, they are turned from two pieces of wood glued together, and therefore half of the cup is different from the other half.


Keith, I can see what you mean form the photo on the site, however the cups I have are not jointed but a single piece. Maybe it depends on the pieces of wood Joe gets?

Angelo, lovely cups! The leaf covered ones bring to my mind the Green Man, there's lots of possible presentational ideas there loosely based around Pagan, Wicca, Solstice etc.

My cup pictured above was made by Angelo Iafrate and is very similar to one pictured in the Cups and Balls Museum. I bought a set of Mike Rogers chopped manipulation balls and a load ball for it, being inspired by Bill's photo of his Museum cup. I bought my cup on the Café Let's Make a Deal section and it's one of my prized possessions.

I used to do some wood turning, but not even in my dreams did my skill approach Angelo's. I found a source of air dried black walnut that I used as my stock. Even with naturally cured wood, it can warp overnight if you put a finish on only one side.

You need to see them "in person."

The join in my Porper cocobolo cups is almost unnoticeable. You can't feel it when you run your fingers over the wood. That's the sign of a great joint.

Cocobolo is very hard and "flinty" to turn. You don't get shavings from cocobolo you get bits and pieces and lots of dust. Most people who work lotsa cocobolo may not be allergic to it when they start but have to stop using it because they have developed an allergy to it over time. So far I'm still able to work with it

So far the bodies of my cups is made from one piece of wood. the beads are added onto the cup. the single bead is set into a recess and the double n=bead rim has a mortice and tenon joint so that they will stand up to any routine. I have, waiting in the wings, Bocote, Padauk, several sets of cocobolo, walnut and maple burl

There Aint No Such Thing As A Free Beer == a take-off from TAANSTAFL, which had to do with a free lunch.

@angelo -- If you want to see something gross, turn ebony without a repirator, then blow your nose. Smile

The feathered cups arrived this morning. They passed "the wife test" with a "WOW! Those are beautiful!"

They are on the photo table right now, awaiting photography.

They should be in the database tonight, and maybe on the regular pages as well.

I'm working on that right now. I have four sets to add tonight.
