Guides to building props or using certain techniques and materials

Steel Headboard for “In the Wake”

The next play to open here at the Public Theater is “In the Wake”, by Lisa Kron. One of the props they needed was a headboard. The design was based off of an existing style of headboard, but as the bed was a custom size to allow it to fit between the scenery, the headboard would also need to be a custom size. In addition, the bed moved to the middle of the stage where the headboard would be freestanding, and I was told the actresses would be leaning against it. For those reasons, a store-bought headboard would not fit the requirements. It had to be built, and it had to be built out of steel.

Since the design of the headboard was based around a repetitive pattern, the first thing I did was break it apart to make a cut list. I divided the pieces so the cut list would be as straight forward as possible, with as few angles as I could get away with. I managed to come up with a way where most of the pieces were straight cuts, and only a third of the pieces would need 45 degree angle cuts.

Before I could begin welding, I needed to create a jig. As you may already know, a jig is a device to maintain the spatial relationships between your materials, or between your tool and the materials. In this case, I wanted a jig that would allow me to lay my pieces of steel down in a consistent pattern while welding them together.

I thought I was being clever by making only one section of the jig. The idea was that it would keep everything consistent. In hindsight, I should have made a jig of the entire piece. Then I could have dry-fit all the steel before welding it together, and adjusted the pieces individually to ensure they all fit. The way I did it, the piece as a whole ended up just slightly “off”, with the minute inconsistencies in my jig being amplified through repetition. Even someone as talented as me can still have learning lessons.

As you can see in the following photograph, I had to clamp it to make it fit even after adding just a few pieces.

I decided to TIG weld this project. In theatre, the majority of welding we do is MIG welding steel. TIG welding is useful if you need to weld stainless steel, aluminum, brass, or if you need to weld two different kinds of metal together. In this case, I was TIG welding regular steel; even though it takes a lot longer, I could weld with little to no filler rod, which left me with very clean welds, and no spatter. I felt it was important for this piece since the cleanliness of the lines was an important part of the design. Plus, I wanted to brush up on my TIG welding skills.

Even though I had TIG welded before, I still learned some new things about it. For one, the difference between using Argon and using an Argon/Carbon Dioxide mix is astounding. If you aren’t using pure Argon, you can literally watch impurities form on your tungsten electrode while you weld. Another tip I learned was that it is important to grind your electrode parallel to its direction, as opposed to in circles. TIG welding is so precise and exacting that little piddling tips like these really go a long way. Its actually a very Zen way to weld, if you have the time.

Once all the pieces were in place, my next step was to add Bondo to smooth over all the welds and fill all the holes. Bondo will cause nerve damage over time, so you must work with adequate ventilation and wear a respirator with cartridges that filter organic vapors. You should also wear gloves and sleeves to keep it off your skin, as it is a skin sensitizer as well. Remember that even after it hardens, you still need protective equipment while sanding it, as you release dust and fumes that can still harm you. With the proper safety precautions, Bondo is an incredibly versatile material for many projects.

After I sanded it all down, all that was left was to attach it to the bed, prime it, and paint it.

Fake Dead Lamb Part Three

Welcome to the thrilling conclusion of this fake dead lamb I’ve built. If you haven’t already, please read part one and part two so you can catch up and see what has happened before.

When last we left our lamb, I had given it a “meat pocket” to experiment filling with fake meat that the actors could eat on stage. The prop master (Matt Hodges) and the chef figured out what they wanted, so I had the go-ahead to carve out the rest of the pockets. The main one was going to be the ribcage: Matt had some fake rib bones that would be covered with meat. The actors would rib nearly the entire rib cage out and break it apart one by one.

As I mentioned in the last post, the silicone rubber peels right away from the foam body.

I carved away a lot of the foam, even making a hole through the body. The idea was to make the lamb appear like it would at the end of a meal; the fake meat would fill it in. I also wanted to put some contrast in the color, as the outside would have crispy, seasoned skin while the inside would be just fat and muscle.

The lamb needed a tongue. I decided I would carve one, mold it, and cast it directly out of Dragon Skin.

I cut it out of a scrap piece of MDF and carved it down as quickly as I could. I tried to add some taste buds and texture too by hitting it with pointy things. I took a piece of Kleen Klay, shoved the tongue inside and pulled it out. The Kleen Klay liked that. A lot of oil-based clays contain sulfur, which keeps silicone rubber from curing, which is not conducive to casting pieces in it. Kleen Klay is one of the types that is sulfur-free.

I don’t think you’ll find this method in Thurston James’ book on molding and casting, but it served my purposes fine; namely, I had poured a batch of silicone rubber within twenty minutes of starting the whole process.

After a little over 75 minutes, I broke the clay mold open and removed the tongue. None of the clay stuck to it, but I could tell it was still a bit tacky on the outside. Not to worry; the instruction booklet says that might happen occasionally. The solution is to let it sit out and cure in the air for a few minutes. If it remains tacky after a long enough time, you have to remove that layer; in this case, I was lucky and the rubber cured fully on its own. And I got some tongue!

That’s pretty much the end of the process. I added more thin coats to color and tint the lamb until it matched the research. There was one more meat pocket in the back leg; I carved it to look like it was eaten to the bone.

So there you have it: an easy-to-clean fake dead lamb with the ability to fill it with fake food for actors to eat on stage. As I mentioned earlier, now I know how to improve on my process for the next time I need to make a fake dead lamb.

Fake Dead Lamb Part Two

(This is part two of a series. Read Part One to catch up).

If you remember the body I built for The Bacchae last year, you remember I used Dragon Skin for the majority of the project. At the time, we were using Dragon Skin Q, which was a formulation that set in 75 minutes. I discovered this year that they renamed all the products. Dragon Skin Q is now Dragon Skin 10 Fast. Regular Dragon Skin is now Dragon Skin 10 Medium. They also have Dragon Skin 20 and 30, which are new products to give different hardnesses. I learned all that at the Compleat Sculptor, which is a really great store here in NYC.

Anyway, after I coated the whole lamb with a skin of Dragon Skin, I began adding more layers with different colors. Silicone rubber sticks great to itself, and it’s easy to color with a number of pigments that they sell. You can also control the translucency and consistency of the Dragon Skin you’re putting on, which makes it possible to create a very dimensional and realistic coating.

Again, it sets up in only 75 minutes. I was also adding Thi-Vex, another Smooth-On product which thickens the silicone rubber; just a few drops makes it possible to brush it onto vertical surfaces without oozing off. You can really build up a lot of layers quickly, which was vital for the short time-frame of this project.

More color layers added

At this point, I needed to reshape some of the parts to match the research better. As I mentioned in the previous part, silicone rubber doesn’t actually stick to anything but itself. The reason it stays on the lamb is because it completely surrounds it and until you peel it away, it has a bit of surface tension and suction holding it on. I needed to slice my lamb open though, and the “skin” peeled right away, even though the body is made of fairly fragile urethane foam. Once I carved the foam into a more-correct looking shape, I folded and sort of tucked the skin back around. Some more Dragon Skin “glued” it back together, and after a few more coats, the colors blended together so well you couldn’t see the cuts anymore.

You’ll notice in the next picture I also cut the front legs down, so they would match the research better. In a bit, the back legs will be chopped in half as well. You’ll also notice the colors are fairly exaggerated. The reason is two-fold. First, once it gets on stage under lights, it will look less exaggerated. I found in making the body for The Bacchae that subtle effects disappear into a muddy mess on stage, and a bit of overemphasizing of colors and details is necessary to read from the audience. Second, the whole lamb is going to get a brown glaze over it, which will dull down the contrast and colors quite a bit.

Looking crispy

Now, one of the additional tricks to this prop is that the actors need to be able to pull chunks of meat off of it and eat it in front of the audience. To that end, I carved out a hunk in the front leg as a test. We had a chef who was working on a vegetarian fake meat substance to fill it with. My goal was to make it look like what would be left after the eating is finished.

At this point, I was ready to start adding the final coats to bring the whole thing together. In the research, the outer skin looked like it was heavily seasoned. I found some coarse sand that resembled the crushed pepper in some of the photographs, and mixed it into a batch of brownish Dragon Skin. Platinum-cure RTV silicone rubber only reacts with a few things: sulfur and latex are some of the more common things to watch out for. Otherwise, you can kind of mix anything you want in there like it’s paint.

Fake Dead Lamb Part One

I was recently contacted about making a dead cooked lamb for The Little Foxes at New York Theatre Workshop. This was an interesting prop. The creative team made a film in which they slaughtered a lamb, cleaned and prepared it, and then roasted it on a spit. They played this video during the performance, and then the actors carried out a tray with what was supposed to be the same lamb. They then tear into it with their bare hands and eat parts of it. Obviously, they couldn’t use the same lamb as in the video, as it would only last one performance. Another curve ball was that some of the actors were vegetarian.

Thus, the idea was to construct a fake lamb which matched the appearance of the lamb in the video. This lamb would have “pockets” which could hold some kind of fake meat. Matt Hodges, the prop master, brought in a vegan chef to deal with the execution of a faux meat product. The whole thing would also need to be easy to clean, otherwise there would be serious hygiene and safety problems after a few performances.

I first mentioned Dragon Skin over a year ago on this blog, and used it extensively to build the body for our production of The Bacchae. You can reread part one and part two and see the various heads we had to make. If you are more interested in what it is or how to work with it, check those articles out. I decided on Dragon Skin for two reasons: first, I knew I could achieve the right look with it. Second, nothing really sticks to silicone rubber except silicone rubber, so it could be hosed down with water or washed in the sink with soap without worrying about it falling apart or dissolving. Finally, it is pretty fast to work with, and since I ended up with little over a week to turn this guy around, I couldn’t afford to work with something that took all day to dry.

To save time, we started with a taxidermy form. Matt Hodges had measurements and photographs of the kind of lamb they would use, and found a small deer form from Van Dykes which was the closest facsimile. Also, I hope I don’t need to mention that I had a lot of reference photographs to work from, which is integral to this kind of project.

The first step was cutting it apart and reassembling it. First, it was not in the correct pose. Second, it would look ridiculous to have a stiff lamb on stage, especially with the actors tearing at it. It needed some movement, so I had to make the joints loose.

Cutting the form apart

The neck was where the most movement was possible. I got rid of the entire foam piece, and replaced it with several pieces of thick rope. I also added some slices of PVC pipe to bulk it up and act as vertebrae.

I wired the whole thing together when I was happy with it. I spent some time tweaking the lengths of the different rope pieces and the placement of the vertebrae until it had the kind of movement that looked realistic to me.

I decided I would wrap the whole neck with muslin dipped in Rosco FlexBond.  When you mix Dragon Skin, it’s fairly viscous and runny; you can add thickener to it to make it thick enough to brush on and stay on vertical surfaces. Either way, you need a surface for it to stick to. I suppose the “correct” way to construct a prop like this is to make a mold of the body, and suspend the armature inside, then cast the whole thing with Dragon Skin. It’s how they construct animatronic creatures. That way would be far to time and money intensive, though. In retrospect, I could have slipped pantyhose over the neck to achieve the same thing. Ah well, I’ll keep that in mind for the next dead lamb I make.

The legs were also reattached with strips of muslin dipped in FlexBond. I realized the FlexBond took far too long to dry, so when it came time to attach the front legs, I just used Gaffers tape. Really, I only needed to hold them in place until the whole piece could be coated in Dragon Skin.

At this point I decided I would cover the whole lamb in sort of a “base coat” of Dragon Skin, and then brush on the various colors and lumps of flesh. As I mentioned above, silicone rubber only sticks to more silicone rubber, so you can peel it away from the foam which the lamb is made out of. The only way to keep that from happening is to cover the whole thing so it’s one continuous “shell”. I figured I would pour the first coat on rather than brushing it, so it could flow into every crack and crevice. I put up a “dam” with aluminum foil to keep it from running down the sides.

I made the base coat a very opaque off-white to match the foam. This would help give it a uniform color as well. In retrospect, I may reconsider these first few steps. It took a lot of Dragon Skin to cover up all the white Dragon Skin from the first coat. On the other hand, it’s always better to work from light to dark when building something up with many translucent layers. Again, maybe I can try something different when I build my next fake cooked lamb.

You may have noticed in the first picture that the animal’s head isn’t quite right; it has a section cut out with a wood plate hidden inside. It’s where you are supposed to mount the antlers of the deer you are trying to recreate. I needed to fill that area in. I decided to try a product called Magic-Sculpt. I’ve always liked doing quick modeling with epoxy putty. It’s easy to work with, it adheres to many things, and when it sets, it’s rock hard. Magic-Sculpt is essentially epoxy putty formulated specifically for modeling. It doesn’t shrink or crack, and with a little bit of water, you can smooth it to a slick surface while you’re manipulating it. You can also buy large quantities of it for far cheaper than you can buy the same quantities of epoxy putty from the hardware store. Their website says you can work with it sans gloves; that is absurd. Epoxies are skin sensitizers, and with enough exposure, you can develop severe allergies. Wear nitrile gloves when working with it.

I shaped a chunk of it to fill out the top of the skull. I also added some in the mouth to sculpt out some teeth.

For now, let’s let this little guy dry before moving on. Continue on to the second part of this build.

Paper Props from Capeman

We just finished our summer season in Central Park with a theatricalized concert version of “Capeman”, the musical by Paul Simon. Though it got less-than-stellar reviews the first time around (and cost $11 million for 68 performances), this reincarnation was very well-received and quite enjoyable. It was also a lot of fun to work on, sort of like a chaser to the stomach-churning intensity of the two Shakespeare shows in repertory we did at the beginning of the summer (though having one of them transfer to Broadway is a nice feather in the cap). Plus, production meetings at the end of a long day of tech become a lot more fun when Paul Simon is giving you notes.

Anyway, the show had a few paper props I made; these are two of them, one of which made it in, the other which was cut. If you’re unfamiliar with the story, here’s a quick summary so you can follow along. “Capeman” is a fictionalized retelling of a real event. In 1959,  during a gang fight in Hell’s Kitchen (a New York City neighborhood), a 15-year old named Salvador Agron stabbed and killed two teenagers. He wore a cape, hence the nickname; the story exploded in the news media. He was convicted and placed on death row, but his sentence was lessened to life in prison. The musical follows his early life in Puerto Rico, the stabbing, his imprisonment, and his search for redemption and salvation while in prison.

The airline ticket is given to Agron’s mother while they lived in Mayagüez, Puerto Rico, by a New York preacher who wishes to marry her. As the show is based on a real event within the last century, I was able to dig up a lot of historical information and primary sources right on the internet. Several sites in particular came in handy. Airline History has a database showing which airlines were operational in different parts of the world throughout the history of aviation. They also have a lot of images of airline tickets. The front cover is an early 1950s ticket from Caribair, an airline that flew out of Mayagüez during the time period of the show. I liked the artwork of it, so I copied it “as is”. I resized it to the size of a typical airline ticket at that time, which I found by looking at several 1950s airline tickets on eBay that listed dimensions in their descriptions.

Airline Timetable Images was another great site I used. Though they cover timetables throughout history, rather than tickets, the artwork is still the same. This is where I found the back cover for my ticket shown above. I resized it and changed the colors to match the front cover. Airtimes is another great source for these kinds of images and information.

Inside pages of the airplane ticket

These are the inside pages. I made these from bits and pieces of ticket images I found from the previously mentioned sites, as well as eBay. It’s always a little harder to find images of the boring parts of ephemera, since most sites only scan and display the fun colorful parts. Also, the actual ticket part is taken by the airlines which tend to throw them away, as opposed to the traveler who is more likely to keep it as a souvenir. I’ve never even bought a real paper airplane ticket in all the times I’ve flown, so I couldn’t use my own memories as a reference.

I think what I came up with was close enough, particularly since they never display the inside of the ticket to the audience. I even remembered to check which airports existed in New York City at this time period; she couldn’t very well have a ticket in 1953 from Mayagüez to JFK!

Several vintage postcard options

I also made some postcards. I made three, but they were only going to use one. I thought these three were different enough to give them some choices. I really liked the red one on the right, as it reminded me of “West Side Story”, which was happening during this same time period and which dealt with some of the same issues and locations as the real Capeman saga. During rehearsal, they decided to change the postcard to a letter in an envelope.

Back of the postcard

I found an image of the back of a postcard from this time period as well. I printed the stamp image out separately and cut it out with those craft scissors that give you a wavy edge. Jay has several postal ink stamps in his tool bag, so we finished this off with a cancellation mark and a date stamp. It’s the little details like that which add so much more depth to a paper prop without adding too much effort.
