So, this will take you about 2 hours to put together the first time, and about a half hour thereafter. Two people can do it, more people makes it more fun and go faster. An unleashed Old English Sheepdog puppy slows things up. Beer makes it lopsided.
Disclaimer: We're not responsible for any errors in this following list; you should confirm this with your supplier before ordering. If we messed up, it was the beer or the dog.
Here's what you need to put this together:
Tools
1 hammer
1 screwdriver (does not really matter what type)
1 circular saw (required if you don't get pipes cut at store)
1 circular saw blade for cutting EMT pipe (required if you don't get pipes cut at store)
1 DVD player source (laptop, desktop PC, portable DVD player, etc)
1 set of speakers compatible with the source
1 set of cables (you'll have to figure this out on your own depending on your source and speakers. Danny has a 50ft SVGA cable from sfcable.com, power extension cords, and cabling that came with his speakers. that's all he needed)
If you buy these at Home Depot or Lowes
or some place like that, get them to cut these lengths for you, it will
save a LOT of time

You can get the above fittings, bungees, and tarp from any of the following sites (with last price quote (less shipping and tax) provided, in order of least expensive first by the vendors):
This last website advertises the same type interfaces but we do not have pricing currently: http://www.craftcanopy.com.
(If you feel your firm should be listed above, contact us)
By the way, we said 30 and 20 for the numbers of 6- and 12-inch bungees you need, but they come in packs of 25, just so you know. You might find vendors that don't want to split up the packs of 25 and may charge you less for a whole pack.
Note that you can have an alternative configuration that provides for three front support legs, as we'll describe in the step by step. This would entail:
2 F4a (instead of 2 F3a)
1 F5 (instead of 1 F4a )
Here's the vendors that have parts for this extended collection:
These would replace the three front foundation fittings, and allow you to have
any length of EMT piping that provides better support against the screen going
forward — Danny is experimenting with that now. Theoretically, if the rear braces
are anchored well, you would not need this. We're also checking into a framed
version without the anchors in the ground, for asphault applications. Check
back here for more details as we flesh that out.
Warning
If there is one thing that has concerned us about the fittings is that
quality varies substantially. Danny is trying to ascertain which vendors sell
the best ones, but even that can vary from month to month. The screw eyes will
sheer off occassionally, so you should ask for extra screw eyes when you order.
The eyebolts will vary by source manufacturer on size. Some will come with smaller
eyebolts and some with larger eyebolts. You can't specify which you get and
right now they are a mixed lot- some are 1/4 inch and some are 5/16 inch (best).
What we are seeing is a transitional move to the larger eyebolts which will
take time to complete due to restocking. So you can't always request the larger
and be assured of getting them at this time. They can't be sure of what will
come in on the ship themselves! (Thanks to Donna at http://www.shelters-to-go.com
for this background) .
Putting it Together, Step-by-Step
The first step is an inventory to make sure you have all the right pieces.
Lay out all your fittings by group, make sure you have the right number in
each group, and you have the bungees and of course the screen tarp. Here are
the general diagrams of what you are trying to accomplish (Diag.
1 & Diag.
2). Two alternative plans that we are experimenting with include a version
with front supports and an alternate rear leg support system. The alternative
front support requires extra parts listed above (Diag.
3 & Diag.
4). We don't have a parts listing for the alternative rear support system
yet — (Diag.
5 & Diag.
6) shows how it can be done. (Screen
Diagram with identified parts)
If you bought the piping
at a place the cut the pipes for you, that's great. If not, you have to cut
them yourself. You can use a hacksaw, but the more lazy of us (Danny) would
buy a $1.49 blade for your circular saw that will cut the pipe. These blades
are made up of some sort of abrasive that is not only on the tips, but on
the sides too. So, after you cut the pipe, you can also use the sides of the
blades (while spinning) to 'sand' down the rough edges of the cut. (Naturally,
your manual probably says to do nothing of the sort, and you do so at your
own risk (<-disclaimer again), but it works. And the kids love the neat sparks.
Even if you get the pipes cut at the store, you might want to get the blade
anyway just for this purpose so you can have a nice rounded edge that no one
cuts their finger on. This stuff can be sharp. Watch out! Warning: Wear some
glasses, even if only sunglasses, as shards do pop off of these pipes while
cutting them.
NOTE: The instructions
from here on depend on which of the three framing formats you have chosen
to do. The instructions here will be for the first and most common format
— the anchored format — but you following the same general process and path
for the others as well.
Lay out the pipes for
the side trusses. Here are the pieces you need to make each end truss are
the following:
Start with the
end trusses by grabbing the top fitting in each, the two P4CL/R fittings.
This is probably the most distinctive piece of the frame because of the low
angle of the triangle — it's obviously the top piece for each end.
Remember: there is no piece
like that in the middle. Why? You don't want a middle brace because, in a
slight wind, the vertical middle brace would be visible in a wind-blown screen.
So the middle top bar piece is merely a T-bar like fitting, the FTa fitting,
to provide the need support from the back. But we digress.
Orient the top
truss fitting in your mind. Looking at it in your hand, you'll see part of
the fitting that goes out to the right (or left depending on the piece) —
this goes towards the audience. There are two downward fitting sockets that
go towards the ground. The vertical piece that will be exactly perpendicular
to the ground is the fitting that will actually hold the screen. The socket
that goes off at an angle is the socket that houses one of the back supports.
And the socket pointed towards or away from you, houses the horizontal cross
bar that also holds up the screen. Insert a 120-inch (10-foot) length of EMT
into the socket for the back support, and insert a 117-inch length pipe into
the vertical front brace for the screen. You should see two sides of a triangle.
Tighten the screweyes enough to hold the pieces in place. Do this for both
trusses.
Important:
Slide onto each angled, 120-inch bar, an adjustable fitting (AT). The nut/bolt
connector should be on the top, so that the socket is facing towards the bottom
of the frame. Hand tighten the AT into place up against the top fitting. This
is one of those "Oh Crap, I forgot the..." that you will want to make sure
is on there now.
Grab your next
two pairs of fittings for the trusses: P4EL (or ER, whichever side you are
working on) and F4a. Orient yourself again. These fittings have no audience
side socket, just a socket for vertical support bar and two horizontal support
bars. Take your 29.5 inch EMT bar into the two sockets that play the role
of the bottom of the triangle for the truss thus far. Orient this so that
the screen vertical support bar so that it is perpendicular to the front screen
supporting vertical braces. Do this for each truss and hand tighten.
Grab a 57-inch
length, a 60-inch length, and a 44-inch lengths of EMT pipe. These represent
the front vertical, rear support, and bottom foundation bars. Grab fittings
P3DW and F3a, and orient them the same way you did the middle fittings on
the truss. (Again, note that if you have chosen to get the fittings with front
supports, you would be grabbing fittings F4a instead of F3a here. And if you
have the full frame version, well that's something else we don't know yet,
but there'd be some differences the presumably you've figured out since we
didn't.) Slide the fittings/bar onto the base of the trust. Once on, the botton
horizontal bar should be parallel to the middle support bar of the truss,
and the bottom should be perpendicular to the front vertical screen support.
Hand tighten the fittings.
OK, now you should
have two completed side trusses.
Run your eye along the pipes and fittings and make sure that everything seems
pretty square and lined up. Measure the distance from fitting to fitting and
compare with the other truss. Even them up — you want this balanced. Once
you are satisfied with the appearance, use your screwdriver as a level on
the screweyes to tighten them a little more. Caution: Don't overtighten. These
screweyes can sheer off. We're hunting for higher quality fittings but until
we find them, this warning stands. Ask for extra screweyes when ordering,
or have some on hand...you'll need them every once and a while.
Now we are ready
for the middle truss. This looks just like the side trusses, except there
is no middle audience side vertical screen support bar. Start with the T-shaped
fitting FTa and a 10 foot EMT pipe.
Again slide an adjustable fitting (AT) onto the 120-inch bar. Don't forget
this! The nut/bolt connector should be on the top, so that the socket is facing
towards the bottom of the frame. Hand tighten the AT into place up against
the top fitting. Connect this bar into the same basic middle and bottom supports
as with the above side trusses. You'll need fittings 2-F4a, 1-P5E, and 1-P4DW,
as well as a 29.5-inch pipe and a 44-inch pipe. When done, the middle truss
should be as square, lined up, and proportioned as the side trusses. Use your
square and measuring tape again to make sure this is just like the side trusses.
Tip: The measuring tape is a good indicator of pipes that are not
seated all the way in, or of a fitting that cuts off prematurely due to some
weld spots in the pipe. So make use of it.
As the kids say,
"Now the fun part begins!" The rest of the structure goes up fast, because
you are dealing with mostly the long 10-foot EMT pipes and you are just piecing
things together. Align the trusses about 10-feet from one another, side-middle-side,
so that you can place the pipes in between them and connect. Tip: Do this
where you want the screen to actually go. You have to orient the trusses so
that the vertical screen support/audience facing supports are down on the
ground, and the slanted side of the trusses is on the top. Grab five 10-foot
EMT pipes, and insert them into one side truss. Do not insert any into the
middle truss until all five are seated into the side truss. Hand tighten.
Now move the middle truss into position, seating all five about the same time,
so that none bind against the fittings. Hand tighten. Measure with measuring
tape to make sure all of them are in the same length and it is square. Tighten
with screwdriver (as lever) again. Do the same with the other truss. When
done, you should have straight lines and clean angles. The three adjustable
AT fittings should be on top, all facing the right way, towards the bottom
of the frame.
Take three 10-foot
EMT pipes and fit them into the AT fittings. Have the EMT pipe extend about
1" above the top of the AT fitting. Make sure the AT fittings are on the support
pipes such that these back support bars will go straight back. Tighten all
of these down with the screwdriver (as lever). Add, onto the bottom end of
each of these three EMT pipes, the FCa fitting. Again tighten well. Measure
and make sure all the lengths are about the same (sometimes these bottom FCa
fittings don't have a mid-welding joint and slide all the way through and
so you want to make sure that your EMT pipes are only about half way into
the FCa socket, leaving room for the other EMT pipe to slot in on the other
side).
At this point,
you should have a fairly finished frame. Everything should be lined up well.
All connections should be fairly tight.
Whew! Now's the time to put the screen on. We've tried to think of some better
ways to do this, but we're still lacking a suave and sophisticated 007 way
to slink in and put the screen on and then get out without getting hurt. So
our process de jour is to lift the top of the screen frame up about 2 feet
off the ground, and prop it up at the three joints on something of similar
height, like 3 chairs, or three saw horses, or three kegs of beer (oops, Pat
said that). Grab your ball bungees and tarp. Unfold the screen tarp — do this
carefully because each extra wrinkle you add is one more wrinkle on your screen.
Use the 12-inch ball bungee to connect each corner of the tarp. (If you've
never used a ball bungee, they stay connected by the pressure placed on the
loop end against the ball, so you just tuck the ball into the loop part, under
pressure and it should stay.) Try to do opposite ends of the tarp first so
you can better center the screen evenly within your frame. Depending on the
size of the tarp and the proximity to the frame supports, use 6-inch or 12-inch
bungees to connect the tarp to the frame. Try the 6-inch ones first as that
will provide the best tension, but if it is too hard, use the 12-inch bungees
and consider wrapping them once around the EMT pipe before locking the ball
into the bungee cord. Adjust the bungees as needed to get a smooth surface
on the tarp.
Now you are ready
to put up your screen (Music Cue: Drum Roll.) So here's the last step. Oh
did we tell you that if you've read this far and are doing this, that you
should buy one of our books. Come on, it's only fair. Danny's got 4 kids to
put through college and Pat's got his beagle Opie to feed. Here are the URLs
again - one click and you've boosted our Amazon.com ratings:
So, thanks for
that. (Hey you in the back, you didn't order one!) So now is the time to use
the last three 10-foot EMT pipes you'll need (you may have a few extra left
over, but those are spares). Attach them to the three pipes attached to the
adjustable AT fittings. Tighten them securely with the screwdriver as a lever.
Don't over tighten, you're almost home free. Note: Check the wind
— is it blowing hard? If so, wait a while to put it up. If not, proceed. With
some friends, relatives, kids, neighbors, people driving by, etc., have three
people hold the poles while others 'walk up' the front of the frame, gradually
lifting it into position. The frame should stand firm and upright, and the
three far rear support poles somewhat free to move. Take three 18-24-inch
scrap pieces of EMT. You are going to use these as spikes to secure the rear
supports. Get the remaining three AT adjustable fittings. You will want to
slide these over the ends of the three rear support poles — with the adjustable
socket facing towards the bottom of the pipe (in other words, with the nuts
and bolts on underneath of the EMT and facing so that when the socket is swiveled
towards the rear support bar, it is facing down not up the EMT piping).
You want to hammer this into the ground at a 90 degree angle to your rear
support bar. Tip:Grab a spare piece of 2x4 or wood, and hold that
over the spike while you drive it to protect the endpoints of the EMT — this
pipe is somewhat soft and will dent, and then you won't be able to slide the
AT fitting over it. When done hammering it in, slide the AT fitting into the
now-grounded spike, and secure with the screwdriver as a lever. Do this for
all three of the rear support bars. Tip: The middle bar has an important
role in making sure the screen is fully taut. You can move this back and forth
a bit to optimize your screen — do that before placing your spike in the ground.
For most people,
the setup is now done. If you purchased the additional fittings to allow for
front bracing pipes, you can insert 24-inch to 30-inch pipes there now, and
then you are done. If you think you will have a very windy evening, it never
hurts to throw something heavy across the 44-inch bottom truss bars to further
weight them down, but we have not yet found that to be necessary. It's up
to you. While you still have to set up the electronics after this, the framing
part is done. Now you can call your spouse over so he/she can say, "Very nice,
dear."
We get asked a
lot about how long you can keep it up. Well, Danny shows movies every weekend
at our place in Maine, and he just keeps the frame together and merely take
off the tarp each time — no big deal. In Connecticut, he has just left it
up to see if it would blow down, and it has not in 2 months. In Maine, he's
seen it sustain 20mph winds, so it can hold its own in moderate weather, but
to be safe, you should at least take the screen down and not be as lazy as
Danny. (Danny keeps talking about a pulley-based removable frame but that's
all it is,...talk!)
Of course, NO drive-in/outdoor theater would be complete without the requisite
Popcorn Stand, where it's $1 for a bag of popcorn and a dixie cup of ice tea
(overly sweetened!).
Taking the screen
apart goes very fast. But before you go to take it down, you have a decision
to make. We don't have enough experience with this yet — and enough feedback
from people (please write) — to say whether what we are now going to propose
makes sense or not — Danny intends to do it. As you disassemble the frame
you can drill holes where each screweye hit the pipe. This will make for a
stronger and more rigid frame, and less likelihood that the screweyes will
sheer off when you are putting them in. It also means, however, that you need
to mark, with the permanent marker, all your joints, so you can easily put
it back together again — see, the fittings are not consistent with where they
put the screweye holes, so you really do need to match the EMT pipes with
their appropriate fitting sockets if you drill holes. If you don't drill holes,
you can put any 10 foot pipe where 10 foot pipes need to go. In any case,
do make use of the permanent black pen to mark things in your own way, so
it will go together faster next time.
Store the fittings in
a canvas bag like this
one. To make storing all the pipes easier, consider getting some velcro
straps like
these.
