Today marks 75 years on the planet. It has been a minute and things have changed. The phone I’m posting this on didn’t exist even in science fiction back then!

More Milton aftermath: about an 80’ oak tree downed on our property, the top is up against the (distant) neighbor’s house. Had it fallen the opposite direction we would be homeless. Thanks, Milty, for your forbearance!

Addendum: did a proper measurement, the oak was 84’ tall.

Lost power Wednesday evening. Due to my 24/7 oxygen needs we bugged out to a neighbor/friend with a generator. 48 hours until power was restored. Tons of tree debris and water standing on our eastern acre, but the house was untouched. Tamara & houseguests got stung by black-face hornets in a nest on a downed branch by our front porch (pictured).
Other than that we were spared the worst of Milton!

It is with great sorrow that I share the obituary of my brother, Richard Chapman. He was a man of intelligence, warmth, and humor, and is sorely missed.

“Old mold makers…
just mold away!”

I’d like to indulge in a recap of my experience in sculpting, mold-making, and casting.

In my elementary school years I was bedridden with mononucleosis and my amazing mother taught me how to sculpt with oil-based clay, building forms from simple rolls, spheres and discs.

In 1964 I made my first molds and casts to create a monster-themed chess set. The only available materials were latex rubber and a funky translucent pink polyester resin from the Castolite company.

My professional career has been a wild mashup of overlapping and interleaving jobs. I spent 8 years as an archaeologist, 10 years as a museum exhibit technician, over 6 years as the chief mold maker at a manufacturer of artificial cadavers, 2 years as the sole mold maker at a concrete statuary company, 2 years as the custom mold maker for concrete stamping tools, over 1 year making molds for ceramic slip-casting – all interspersed with creating monumental-scale sculptures, molds, and resin replicas for private individuals, commercial display companies, and theme parks and entertainment companies such as Universal Studios, Busch Gardens, Nickelodeon Studios, and the Orlando Dolphin Hotel.

Now it’s wrap-up time. I have been diagnosed with acute pulmonary failure – fibrosis and emphysema, including “particulate groundglass infiltration” of my lungs from years of fiberglassing (despite my rigorous adherence to wearing organic fume respirators). After 2 weeks in the hospital, I am home under the care of hospice services. I will be on oxygen 24/7 the rest of my life, with my activity level severely curtailed. My molding and casting days are over, although I hope to keep up a little sculpting. I’m going to be offloading tools (including a large motorized rotation casting machine), materials, supplies, cast resin products including fossil replicas, and usable molds.

I may be withdrawing from the field – but, hey, I figure 60 years was a pretty respectable run!

As well as Valentine's Day, today is the birthday of my mother, Eleanor Eliza Finley Chapman. She was a woman of so many talents - author, artist, professional illustrator, to name a few. She read me aloud The Lord of the Rings trilogy in its entirety as bedtime stories, and taught me to draw, paint, and sculpt. She was such a genteel, urbane, and loving woman. After 37 years I still miss her deeply.

Started on a different kind of project - feline gravestones in the style of old New England monuments. The tricky part is figuring out a way to cast them with changeable epitaphs, rather than having to carve the letters into concrete.

I’m finally able to post pictures of my latest project – one hundred 6” tall figurines of a cliff diver, for the Rosa Mexicano Restaurant in the Swan and Dolphin, in Walt Disney World Resorts, Orlando, Florida. (The restaurant is inside the Dolphin Hotel.)

John Gay, the Project Manager, sought local artists rather than farm out the work to distant corporations – an attitude I respect and for which I’m grateful! It was a rather tight deadline. I had 23 working days to create molds of the figurine I was given, then cast, finish, paint, and deliver them. I made 2-piece poured block molds as that was the most expedient. The rubber was SmoothOn Rebound 40 (turquoise color), simply because I had it in stock from a previous project, and didn’t have to wait on shipping. It’s good material but this was not the best use of it – I “burned up” 4 molds producing the figures! I then switched to Rebound 25 (salmon color) which I also had in stock. The pieces were poured in SmoothOn Smooth-Cast 305, a polyurethane resin. It has very low viscosity and a longer working time than many others, allowing me to cast 3 figures at a time before the resin began to gel.

I admire the way the figurines were installed. They are mounted on vertical panels of wavy, blue-green tile, reminiscent of water. The figurines form vertical columns that are like stop-frames of a cliff-diving video, with the divers upright on the top row and sequentially tilting forward until the bottom-row figures are head-down. There are 2 panels, each with 2 sides facing adjacent rooms in the restaurant. In total, 84 figurines were mounted, with the remainder reserved as replacements in case of loss or damage.

This was the largest number of casts of a single object that I have made in one run, in nearly 35 years of professional mold making and resin casting!

I have been making jewelry molds for Debra Peisner of Creativeflow Jewelry Design & Repairs in Tampa, Florida (see link in comments). The rubber I use, Nicem 940, is very translucent and correspondingly hard to photograph!

Here is a typical mold I produce, from which wax copies are cast before investing for casting in precious metals. This set of rings has decorative elements that protrude on each side of the shank (the main body of the ring). I rolled a thin layer of clay and imbedded the rings up to the shank on one side. Reusable walls made of cut strips of melamine board were built around the array and the first half of the rubber poured over them. (I vacuum degas the rubber before pouring and place the mold afterward in a pressure tank at 60 psi.)

The first picture shows the rubber half with the ring models still in it and the bedding clay partly rolled back. Notches are cut into opposite edges of the rubber to provide registration for the second mold half. The second photo shows the mold half with the melamine walls reassembled around it. Amaco Permoplast clay is heated in a microwave, quickly rolled into coils, and finger-smoothed around the seams to prevent leakage of the rubber. This takes far less time than using tape or hot glue and is reusable and easy to remove. After the second rubber half is poured, I cut sprues with a sharpened brass tube and widen their outsides to form a cone that fits the wax injection port. The mold is labeled on both halves using a small metal cutting gouge. The final picture shows the final mold - and demonstrates how unphotogenic the material is! Only a few of the 8 sprues can be seen.

It took a few molds and feedback from Mrs. Peisner before we found a procedure that yielded consistently usable molds. Wax is fussy stuff!
