Building the Mirror Blaze in Pictures XV: Integration Weekend V::We get the First Glimpse of Mirror Blaze at Night!

Last time, our intrepid crew had just finished the build of the internal part of the maze, and had tested the flame effects during the day. Now it was time to test them at night!

Initial reactions were very strong:

Mirror Blaze Night Flame Test #1 (blurry):

Mirror Blaze Night Flame Test #2 “There is a lot of light.”:

Mirror Blaze Night Flame Test #3 (blue flame and backdraft tests):
I really enjoyed the blue flame in this video, and whenever it happened at the event. This set of tests were mostly us calibrating the length of time we needed to open the solenoid to get the optimal flame. If we set it off too quickly, there would be no propane in the accumulator, and we would get a small ‘foop’ flame. Setting if off for too long would give a slowly dwindling flame. The trick was the sweet spot in between.

Complicating this was the backdraft issue, where you had to have some air flow pushing the denser-than-air propane up the tube, or it would fall down and ignite out the bottom of the tube. In practice, we found that warm air (from an immediately previous ignition) was often enough to supply this airflow upwards:

Also note that the tube was starting to get sooty.

Hellblazer also got in on the flame action[1]!

Building the Mirror Blaze in Pictures XIV: Integration Weekend Part IV:

Last time, we talked about what happened when Mirror Blaze encountered water. Today, it is time for fire!

But first, we went and consulted Magical Trevyn. He gave us some advice about scoreboards, and we continued on our way:

If you wish to make a flaming mirror maze from scratch, you must first invent the universe. You also need all of the components. First, we gathered the quartz tube and welded metal stand:

Then we did a few tests of Flamey[1], with Marc offering debugging help from (mostly) upwind:

Then was the part I was most afraid of. I had learned welding approximately 1 week before, and my first ever welded item was going to be supporting our dozens of pounds, expensive and difficult to source quartz tube.

And now we had to attach it to the ground so that nothing would fall over and break the tube. We had the brilliant idea of attaching it with rebar (1/2″ rebar just fit inside the square steel tubing), which meant hammering rebar into the ground (fine), but then aligning the stand with the rebar, and hammering it down onto the rebar. I couldn’t do it myself, and luckily, Patrick was up to the task of making sure my amateur welds didn’t crack under the strain:

Building the Mirror Blaze in Pictures XIII: Integration Weekend Part III:: Rain Strikes!

Last time, we saw our intrepid crew (constructing and) playing with mirrors. Today, this continues, as pictures of people and mirrors are fun.

First, a test of the mirrors (warning: not for the easily spun nauseous):

Then, more panel attachment!:

Then, just before we attached the last couple of mirrors, rain struck! Luckily, we had planned for this, and beyond making sure our gear was in our tent and power tools were covered, Mirror Blaze was fine (or so we thought).

It looked kinda cool with the water droplets:

Sadly, not all was fun and games, as we noticed that our two-way mirrors (the most expensive ones, of course) were susceptible to water damage, it seemed particularly around the holes that we had drilled in them:

Building the Mirror Blaze in Pictures XII: Integration Weekend Part II:: Playing with Mirrors

Last time, our intrepid crew had arrived at the back field, and had just started to build!

The first part of the maze that our crew built was the central triangle:

The following is probably the most useful (and one of the simplest) tools I’ve ever used. Patrick started using it when we were attaching mirrors to post hinges, and it allowed for much, much easier alignment. We ended up purchasing like five of them for the playa build. It is probably correct to say that this simple tool halved the amount of time required for the build. At Canadian Tire (where I purchased them), they’re called ‘Lineup Punches’.

This is the device that saved us.  Patrick used one of these to align hinges with mirrors, and we never looked back.  It would be correct to say that this simple tool halved the time of the build.

Building the Mirror Blaze in Pictures XI: Integration Weekend Part I

Last time, we prepared to set off for the integration weekend. Today, we talk about what transpired there (at least the first part of it!)

Marc had arranged with some friends of his for a large field to be available for the weekend. This allowed us to spread out and use a lot of space to setup. It also offered some interesting logistical challenges. You see, the large trucks (26′, I think) couldn’t make it all the way to the back field, so we had to offload onto pickup trucks[1] for the last leg of the journey. Thankfully, we had two on hand[2]:

Mike runs after one of the smaller trucks, on the way up the hill to the back field.

There was a lot to move, with teams at the large truck unloading, doing transport via pickup truck, and unloading the pickup trucks at the back field.

So, if you’ll recall, the purpose (for us) of this weekend was to do as much of a build as we could, an integration test to make sure that our design and construction for Mirror Blaze were sound. Here’s the overhead view:

The next couple of pictures should give you a sense of the size of the area that we were fortunate enough to have to play with for the integration weekend (and the incredible number of people who came to help out, my apologies for names I’ve missed). Also, you can see the staging area where the pickup trucks would drop off parts for the various installations:

Building the Mirror Blaze in Pictures X: Preparing for the Integration Weekend

Last time, we talked about learning to weld, so that we could build a stand for the quartz tube for the first integration weekend[1].

First, we had to make sure we had all of the parts for our flame effect (and that we had built it!). Luckily, we had purchased all of the parts during our expedition to the excellent Helios makerspace in Montreal (post forthcoming):

The parts for one flame effect 'Flamey'.
The parts for one flame effect ‘Flamey’.

A few days before integration weekend, I recall running around to hardware stores looking for non-abrasive things with high melting temperatures. I found the fabric below (in the welding supply section of a Home Depot, IIRC), along with silicone placemats (not in the welding supply section):

Also, we had not been camping in many many years, so I went to get some inflatable pillows. They were okay, but I would bring ‘real’ pillows next time, unless space was a critical consideration:

Inflatable pillows!  Okay in a pinch, but if space isn't critical, I would use a real one.

Then it was time to pack up and go! Trish drove the truck over to our place (Francis had been at least partially living in our garage for a while), and we started packing! We are still thankful for the many volunteers who tolerated our hinged posts:

Sara, Carrie, and Mike work to ratchet the posts into place.  The posts were extremely effective, but a total bear to move around (thanks for helping us move them!).

Finally, we noticed that the ramp on the truck had a broken phalange, luckily (I think) Trish had found a long (like 10″) nail[3] which we were able to use to solve the problem most adequately:

And then we were off! Stay tuned for next time, when we travel to the countryside and join forces with many other volunteers to build fiery mayhem!

Building the Mirror Blaze in Pictures IX: Learning to Weld

Last time, we paid tribute to some of the many people who came out and helped us build. Today, we’ll talk about our adventures in finding/making/etc. an appropriate stand for the 7’x1′ quartz tube. Your assignment is that you need to find or make or have made a stand that can hold 100+ pounds, is fireproof, and yet is gentle enough on the quartz so as not to cause abrasions or cracks.

This is the tube in question. From the original email, the Outer Diameter was 300mm, with 5.5mm wall thickness x 2134 mm length:

This is the quartz tube, in all its (still slightly packaged) glory.
This is the quartz tube, in all its (still slightly packaged) glory.

IIRC, when we had talked about the issue of making a stand for the tube at one of the S3FA meetings, Carrie had quickly sketched out a diagram which very closely matched what I ended up building. But, since I had never welded before, it took me a while to come around to the idea. We had a couple of weeks left to make this happen (before the integration weekend), so I first tried to go to a custom welding shop to pay them to do it.

Viking Engineering and Costa Railings were both recommended to me, and they both seemed very competent, but they were far too full of work to give me a hand with so little lead time.

I then stopped at a Structube on the way home, on the off chance that there might be something there that could be repurposed into a tube stand. I kept coming back to this chair, which seemed to be a reasonable height off the ground (we needed about a foot for the flame effect under the tube):

I also met these friendly brontosauroid elephants:

But then it was time to knuckle down and actually learn to weld. Dani was kind enough to teach us on very short notice, so I went and purchased the parts (square tube steel is surprisingly inexpensive, and available easily at Canadian Tire).

So, we were taught MIG welding, and here are the machine settings possible, to give you an idea of how it works (IIRC, we were using square steel tubing somewhere between 12-gauge and 16-gauge[1], and I think we were using the center column):

MIG welder settings.  I think we used the center column, somewhere between 12- and 16-gauge.

Welding was really interesting. MIG welding is even easier than soldering (after you get over the initial terror of using a metal chop saw, and only being able to see while the arc is actually arcing). You put your welding tip on the location you want to weld, and it extrudes metal with flux inside automatically, and welds things together. It’s easy to also dissolve the metal you’re trying to weld together, but you can usually fill that in.

Here, you can see a closer view, with a better view of the metal build-up on the weld:

The way we learned, it’s good to start with a small dot to hold things together while you do the more serious welding. Here, you can see the larger ‘H’ of one quarter of the tube stand taking shape:

Building the Mirror Blaze in Pictures VIII: More Friends Come to Help!

The following set of pictures are of our hardy team assembling the inner triangle which would eventually house the flame effect (inside the quartz tube). Note that the posts are 8′ tall, but the two-way mirrors are only attached to the top 6′ of the posts. This made assembly significantly trickier, as they had to be held up while being attached, but it was necessary so that we could attach a swing panel to the bottom so that we could access the flame effect shutoff valve in case of emergency. (Also, two-way mirrors are horrifically expensive, and the fact that they were 2′ shorter was a significant savings.)

Building the Mirror Blaze in Pictures VII: Friends Come to Help!

Last time, we had just made our first panel, and had convinced ourselves that our system would work to build another twenty or so.

Now we just had to make them. So, we put out the call to our friends (and the local burner community), and people came out of the woodwork[1] to help[2]!

Mel and S help Geoff drill the base of a post 5.
Mel and S help Geoff drill the base of a post 5.

Above, you can see Mel and S helping Geoff[3] drill the base of post number 5. If you look closely, you may be able to see that post 5 connects to post 6, that the drill bit is a spade bit, and about 18″ long, and the taped guide on the right side of the post.

You may recall that we were drilling the bases of the posts so that they could accomodate 1/2″ rebar. 1′ of rebar into the posts, and 1-2′ of rebar into the ground (1′ into the ground in the middle of the maze, 2′ into the ground around the perimeter). This drilling was surprisingly tricky to do at the correct angle. You couldn’t do it straight down (so that gravity would help), as the posts were 8′ long. The other issue was that when you tried to drill them sideways, you had to make sure that you were drilling straight in two dimensions at once. The way we solved this was to get them as level as possible, then attach a guide so that the driller could have a chance at seeing both axes at once. From above and behind, the driller can see yaw pretty well, but it’s easy to miss pitch, especially because the drill is heavy. The side guide helped considerably, so that the driller could line the pitch of the drill (and especially drill bit) up with the guide[4].

E literally came out of the woodwork (or at least the shrubbery around the side of the house). It was an eventful day. Even more people came to help! Stay Tuned!

[1]Literally! (Or at least the shrubbery…)

[2]It’s interesting to think about this. I know we’ve enjoyed helping people build large projects in the past. I think people like being part of something, like building something, and it can be very relaxing to work on a task that you know ‘needs’ to be done, and you can focus on the task and not worry too much about the larger project.

[3]Gillian was also there, but I couldn’t find any pictures.

[4]Other fun things were the placement of the hinges so that the hole could be drilled for the rebar without disturbing the hinge screws. Structurally, you would want the hinges attached as close to the bottom of the posts and mirrors as possible, but you’d really want to leave at least a foot at the bottom of the posts so that you could drill into them and not ruin your drill bit on the screws.

Building the Mirror Blaze in Pictures VI: Our First Panel!

Last time, we talked about the Tube(!) arriving, and various bits of design we had to do to safely encapsulate a flame in an acrylic maze. Today, we talk about how we started to build the ‘production'[1] maze.
