"A Head" of Their Time
by Keith Goodrich

Two doctors from Loma Linda Medical Center, California, walked into Turn of the Century, an architectural woodworking mill located in Redlands, California, one day in the early 1980’s. They were looking for a 21” wide joiner that typically could only be found at a commercial woodworking company. We had one.

I was the “mill’s” operations manager. A young “bring-it-on” type in my early 20’s. All of us at the “Mill” were of similar ilk. We were confident we could do-it-all at the time. This attribute was in our favor as local cabinet shops and contractor’s would approach the Mill for tasks that they didn’t have the machinery or expertise to accomplish themselves.

Back to the Doctors....

One was a medical doctor and the other a dentist. They proceeded to describe that they were making a large (think coffee table type) book which contained multiple sectional views of a human head. The section views would be as follows:

- MRI (magnetic resonance image)
- CT (aka “CAT” for computerized axial tomography)
- X-Ray
- Cadaver Head (this is where I come in!)

They inspected (and approved) the joiner and I scheduled them for a day of shop rental to use the joiner.
The doctors arrived on time on their scheduled day and proceeded to set up simple 4x8 table on sawhorses near the joiner. They then set up their professional cameras and lights. Then came the small cooler...

In a small beverage cooler was a 12” diameter by 12” tall piece of 1/8” PVC tube. Inside this tube was a cadaver head centered upright in the tube and “in-filled” around the head with a two-part foam mix that expanded to hold the head firmly in place. This “head-tube” was frozen solid and kept cold in the cooler with dry ice.

This is where I came in...

They needed the head-tube cut in half (on it’s tall orientation) as they would be taking each half of the head-tube and running it over the joiner removing only ~1/16” on each pass. They asked if I would complete this task as I had more experience with the mills’ very large capacity band saw. I proceeded to make the cut and was about halfway through when the sawblade let out a loud screech! I completed the cut from the other direction and when the doc-team inspected the two-halves of the head-tube they discovered the cadaver had a glass eye! Upon removing the glass eye they were ready to begin their joining process.

They stored the head-tube-halves in the cooler and when ready, they would remove one and proceed to run it over the joiner (flat side down of course) to remove the requisite thickness. They then placed the half-tube on the table, marked the half-tube location on the table to ensure proper camera/tube placement, sprayed the exposed half-tube (with the now exposed section of the cadaver head), sprayed it lightly with a glycerin solution (to enhance clarity) and snapped a picture.

I provided a few brief initial tips on using and adjusting the joiner and they proceeded on their own for the rest of the day to complete their photo shoot.

As the day progressed, the shavings collected under the joiner (as any shavings do). However, these particular shavings thawed as the day progressed. This macabre pile of shavings did not go unnoticed by the two tabby shop cats who we continued to shew away until the doctors completed their work, cleaned up and left for the day.

I never did see the final book but I am sure that it was very informative and certainly a “head” of its time!
