Removing wrinkles from the screen

Just to clarify what is meant by ‘wrinkles.  We typically don't see wrinkles like you might see in clothing coming out of the clothes dryer.   Typically, they will be larger and more like a billowing effect.   

Tension on the screen is the key to minimizing these larger wrinkles.   Tension on the screen is secured with bungee cords.  They are elastic, and therefore they will stretch.     

You can add stronger or additional bungee cords to increase the tension.   I have also used strong plastic zip ties.  You can buy them inexpensively at a Home Depot or similar store.   The pros/cons of the Zip tie is that they are quite strong and not elastic.  You can use them to tighten the connection from the screen to the frame.    Since they are rigid, they can snap (break) over time as the sim is used.   If many golf balls hit the side of the screen near the zip tie, that will increase the probability they will snap.

Determining where to tighten the screen depends on the location of the wrinkle.  Generally, you will want to increase the tension along the perpendicular line to the wrinkle.   This can take some experimentation.   

Consider the following example.  In this sim, you can see two wrinkles on the left side of the screen.   The arrows are perpendicular to the wrinkles.  That is the direction where you want to increase the tension.  Tightening in the upper right side of the screen should help.

One word of caution.  It can be tricky to get everything in balance.  Over-tightening and pulling the screen too tightly can introduce wrinkles elsewhere.

Hope this helps.

After adding zip ties to pull up and right, there were still some wrinkles visible, in a new location, as shown below.  The next step is to add additional zip ties, applying pressure upward perpendicular to the remaining wrinkles.

For example, here is the sim we have in our Demo room.  When the projector is off, you can see there are some small areas with wrinkles.  When the projector is on, they are much less visible.
