Veteran Sculptor Repeats Seminar, "Learns Even More"

	Sculptor Pat O'Neill produces miniature historical figurines by casting Poly 15-6 liquid plastic into molds of Poly 74-30 RTV liquid rubber, which capture astonishingly perfect detail from the originals.

In October 1998 sculptor Pat O'Neill attended our Moldmaking & Casting Methods & Materials Seminar/Workshop for the second time; his initial participation was in May 1994. After the latest session Pat said, "I learned even more at the second workshop than at the first. I didn't do a project myself but followed the progress of many of the other attendees. This allowed me to see all the different techniques and new materials that were used."
Pat's business is K&C Associates in Vienna, VA. He sculpts historical military figurines finished in exacting detail, as well as larger custom pieces. When Pat designs a new figure, he collaborates with an archivist who researches the uniforms, and then with an artist who produces an archival print. Working from this print, Pat sculpts his figures in epoxy putty (available at hardware and plumbing-supply stores); it hardens at room temperature to an extremely durable material that can be sanded and cut with woodworking tools. The epoxy figures make excellent permanent models for his Poly 74-30 molds. The finished figurines are sold to museums, collectors, and shops and at military-themed miniature shows. Pat will do custom sculpture as his time permits.
Classic Poly 74-30 mold rubber and Poly 15-6 liquid plastic have been Pat's materials of choice for years. He is now experimenting with our new 1:1-mix PlatSil® 71-20 silicone mold rubber because it demolds in 4 hours, allowing faster turnaround. He is also experimenting with Easy-FloTM 60, which is more fluid and faster setting than Poly 15-6. For producing cold-cast bronze figures in the same molds that he uses for the painted figures, Pat uses PolyPoxy® 1010 and Poly Cure 1212. He is also experimenting with bronze-finished Forton MG and is planning to use Polytek®'s Hydrogel® for some life casts.
Pat left the second seminar with many new ideas that he wants to test. He can be reached at (703) 319-0642.

Moldmaking Scenes, Summer '99


	Bruce Olsen of Thiokol Corp. needed a hand. By using Hydrogel® N and Poly Wax 15, he got one.

		A face only a mother could love—the casting, not the caster. EasyFloTM parts pop right out of this soft and tough TinSil® 70-20 mold for Michael Ford.


	Paul Burrowes displays his Poly 74-30/Cab-O-Sil® brush-on mold and cold-cast bronze casting made at the seminar.

		Using a block pour of Poly 15-3X as a mother mold and a TinSil® flexible liner, Lynn Spitzer produced this PolyFoamTM part.


	Burnishing with 0000 steel wool exposes the metal powder and gives a metallic luster to Susan Long's cold-cast bronze sculpture. The Polygel® 40 mold in its Polygel® 75 shell is visible in the foreground.



	Bernard Thomas of Princeton University made efficient use of his time at the seminar. He was able to produce several cold-cast bronze pieces in addition to a mold and casting of this Aztec calendar.




	Polytek® resins make building a tough, lightweight mold shell as easy as mixing a cup of A and a cup of B. Eugene Ratych chose Poly 1512X thickened with Poly Fiber to build his mold shell.


	All hands on deck! Poly 74-29 stretches as necessary.


	Dennis Pennant of Princeton University made a seamless mold of this architectural part using Polygel® rubber and Polygel® plastic.

		Janese Hexon constructs a parting line before building a mother mold over her Polygel® 40 brush-on mold.

1999/2000 Seminar/Workshop Schedule

October 7 & 8 and December 2 & 3, 1999, are the dates for the last Seminar/Workshops of this century. April 6 & 7 and October 5 & 6 are definite seminar dates for the year 2000. Overflow dates are May 18 & 19, 2000, in the spring, and November 30 & December 1, 2000, for the fall seminar. The overflow seminars will be held only if the two definitely scheduled seminars are oversubscribed.
The two-day sessions will be held at Polytek®'s well-equipped 5,000-square-foot moldmaking and casting demonstration and shop area in the Easton, PA, facility. Each session can accommodate up to 30 people.
A complete review of all Polytek® materials and methods of use is followed by hands-on moldmaking and casting. Each two-day attendee does their own project with the assistance of Polytek® technicians and chemists. In addition to seeing many different materials in use, the objective is for each attendee to make their own mold and casting. The fee for both days, including all materials, is $300 and includes a Manual & Catalog and a video of a portion of a previous session. Advance registration is required.
