How to Build a Cyclorama Part 2

I am finally getting around to part 2 of how to build a cyclorama. I left off with a completed frame for the vertical radius (check out part 1 for full details). So now it was time to skin the corner. I used 1/8″ masonite or MDF tempered hardboard, this was attached using 1 1/4″ crown staples and construction adhesive.

Next we primed the corner with 1-2-3 primer (this has to be done before you can tape and mud or the mud will not adhere to the hard board), then used sheetrock self-adhesive drywall joint tape on all of the seams and  joint compound. The reason we did our mud now was because once the horizontal transition was in place it would be harder to get to this corner.

Now it was time to start the horizontal radius around the floor. In part one I discussed how we created the ribbing pieces and all of the blocking was already precut. We planned out the spacing on the ribbing before cutting our blocking so that we could use our blocking to space each rib correctly. The blocking on the floor was attached using 2 1/4″ tapcons. Each rib had a piece of block on the floor and one vertical on the wall. A level was used to make sure that the vertical blocking stayed plumb.

We then attached the horizontal blocking for our masonite, attaching it with crown staples. We staggered the blocking so that we were able to staple them in, and began to skin the radius. Because the lower part of the radius (where it touched the floor) had little support and was likely to be stepped on, we used thinset to fill the gap to the first piece of blocking. Roughly troweling it in, then applying out construction adhesive and crown stapling in the masonite. We continued this process until we reached the sheet before the corner where the vertical radius met the horizontal radius.

This is where the process got a little tricky. After carefully thinking we decided the best was would be to make 4 pie sharped pieces. We cut out the ribbing for the corner after leaving a 4 inch section on the backside of the radius of the ribbing. This allowed us to put blocking on the top (connected to bottom of vertical radius) because we were not able to put a vertical block on the wall. The blocking going down the ribs were cut into 3″ pieces and staggered down the ribs and we places more blocking on the under side of the vertical radius to attach the masonite to. We then used seamless paper to create a pattern for the masonite.

The pie shaped pieces were then glued and stapled into place using thinset to reenforce the bottom area. There were a few gaps but we didn’t worry about it much because we were going to use joint compound to smooth out the corner anyways. (Note: We used a massive amount of joint compound, 20 gallons to be precise. It had to be layered in with 7 different coats. Because it was so thick I would recommend using 20 minute joint compound. It will greatly reduce the dry time.)

Once all of the masonite was in place the board needed to be primed before it could be taped and mudded. We used some Henry’s skimcoat to  smooth out the transition between the concrete floor and the masonite and began to tape and mud the seams.

After final sand (this took a couple time of sanding and coating) and all the seams were nice and smooth, it was time to prime everything. We used 1-2-3 primer because it seals and well as primes. We coated the floor twice.

Once everything was primed, we painted the floor and walls with a washable and scuff resistant panit. The last thing I did was construct a custom 10′ x 30′ lightbank. The frame was welded together by a local welder and I bought a silk and ultra bounce to cover it. I hung it from the ceiling joist using a steel I beam and a engine hoist.

How to Build a Cyclorama Part 1

We spent good deal of time researching the many different options before deciding what worked best for the studio. Prefab style cyc walls can be a good option, but we decided it was a bit out of the studio’s price range. After cruising the internet and talking to some contractors we took bits of information from each source and came up with our own way of building it. The finished product was a custom 30′x30′x16′ L-shaped cyclorama, with a 3′ radius curve and a concrete floor so that it would be easy to bring automobiles in and out (which we are very happy with).

Now begins the fun part, we started out with a empty warehouse bay that had a few issues that needed to be fixed in order to be able to have a nice cyc. Our space had an epoxy coated floor, one sheetrock wall and one concrete wall. The first issue was the floor, not only did it have cracks, humps and holes that needed to be patched, but it was also painted with an epoxy coating. This was an interesting and time consuming dilemma because neither concrete patch or paint would adhere to the epoxy coating. To fix this we rented a diamond floor grinder that worked great for removing most of the epoxy and flattening out any of the humps in the floor. We then employed Jasco paint and epoxy remover (warning follow the directions and use proper safety equipment, this stuff is nasty) to root out the rest of the epoxy. Then we used a concrete patch (we recommend Henry’s when used with a bonding adhesive) to fill all of the holes and cracks. We did not spend much time on the edges against the walls because I knew that it would be covered up by cyc’s curvature. In the end we had a pretty flat surface with most of the epoxy removed.

After we finished the floor it was time to start working on the walls. First we removed the lower 3′ of the sheet rock of the one wall so that we could cover it with plywood and give ourselves something to attach the curved ribbing to later.

Becuase the other wall was concrete we built a wood stud frame, using concrete anchors to secure it to the wall and floor.

Once the framing was complete and the wall secure, it was time to hang the sheet rock. We started by snapping a level line 3′ up from the floor so that we could place plywood on the bottom (again the plywood is there to give you something to attach the ribbing to). Then taking a couple of straight boards we screwed them off at the level line to give ourselves something to start the first row of sheet rock. Make sure that you are staggering the seams of the sheet rock.

We used a sheet rock jack to lift the sheets up (highly recommend).

After the sheet rock was hung we decided to mud the walls before we put in the radius so that it would be easier to get to. We also had to mud the preexisting sheet rock wall because it had holes and texture sprayed on it. Take your time with the mud; it will take a few coats to get it looking nice (flat wall finishing is hard to do, you may want to call in a professional finisher).

After we were satisfied with the mud we installed the plywood on the bottom of the wall.

The next step was cutting all of the ribbing pieces (arches). It might help to watch this demo video (or a half naked version with Ashley). We started off by cutting our 4×8 sheets of plywood in half making 2-4×4 sheets, this allowed us to get 4 arches out of each sheet. We used a small board with a nail in one end and a hole drilled at the proper length (3ft) on the other end to hold a pencil as a compass. Measuring in from the corner 3 ft down the edge and 3 ft in from the edge we placed the nail where the lines intersected and drew our radius.

Once the first one was drawn out and cut with a jigsaw, we used it as a template to make the rest of the ribbing sections. We used a few bar clamps to clamp all of the ribs together and sanded them to ensure that they were all exactly the same (the tip broke off a couple of the ribs but it really doesn’t matter that much). Then we spent some time cutting all of the blocking and runners (Important!! make sure that your blocking is cut to a size that the rib will cover but also long enough to give the rib support.) Precutting our pieces was helpful before we got started on the radius.

The next major step was to create the vertical radius. To do this we started by installing blocking at 3′ intervals up the wall so that the horizontal ribs would come up to the bottom of the first vertical curve. Once the blocking was level and screwed to the wall, we screwed the rib to the blocking. Next we measured up the distance of our runners and installing the next set of blocking (we made out runners out of 1 x 2 x 8 Furring Strip and cut them to 2′ lengths. You can go heavier if you would like, which will allow you to make you runners longer). After we had the next rib in place we attached the runners using 1 1/2″ crown staples.

This went on until we reached the top of the wall.

Stay tuned for the next installment of how to build a Cyclorama Wall. We will be discussing how we finished our radius and have some links that might help you decide what will work best for you.

I find Helicon Focus to be a piece of software that I use on a regular bases and thought some of you would be interested in learning more about focus stacking.

Ironhorse Sound Stage Shoot!!

Did a shoot at the Ironhorse Sound Stage the other day, what a treat to work in such a large space. I put in a lighting diagram and a set shot so that you could get a feel of what went into this image. I was able to work with a couple of other talented photographers and we built the entire set. It was a fun day. Let me know what you think.

Cheers
