Mounting A Digital Projector From The CeilingFor top-down projection, the most secure way of suspending your projector is to mount it to the ceiling.

Factory Ceiling Projector Mounts

Perhaps the easiest and most secure method is to use a projector mount designed specifically for mounting to the ceiling.

Unless you are using a mirror, (see below) the projector will be pointing directly at the tabletop. Many ceiling mounts don't allow for this configuration. Consider attaching a wall mount to the ceiling to accommodate this need.

Pros:

• Relatively easy to install - the mounting plate is simply bolted to the ceiling.
• Adjustable - ceiling mounts are articulated to allow for adjustments in angle, height, pitch, etc.
• Secure - all factory ceiling mounts hold the projector safely and securely.

Cons:

• Cost - they are typically between $75 and $200.
• Permanency - removal of the projector for other purposes is often difficult.

Home-Made Mounting

The biggest concern in creating a home brewed suspension mechanism is security. A poorly designed or built mount could result in your precious projector crashing to the floor.

The design options in creating your own ceiling mount are practically unlimited, but there are a few basic options you should consider.

Bolts

The undersides of practically all projectors have threaded (4, 5, or 6 mm) mounting holes. You can take advantage of this by bolting your mounting device directly to your projector. Most professional mounts bolt to the projector this way. Look for finger bolts to facilitate removal and re-attachment of the projector without the need for tools.

Clamps

Clamps can be useful in stabilizing and securing the projector. I would discourage any rig that depends on clamps to bear the weight of the projector. In order to hold the projector securely enough, you would have to put too much pressure on the projector casing. There are two basic types of clamps that are appropriate for use: spring clamps and QUICK-GRIP bar clamps. Whichever you decide is best for your application, be sure that the clamp surface that comes into contact with your projector is padded and clean to avoid scratching.

Chains

Chains can be useful in securing and providing adjustment for your rig. They are strong, can be easily adjusted or cut to uniform length, and can be attached to your projector by a thumb screw. A simple and unobtrusive suspension rig can be made using only screw-in hooks, thumb screws, and chains.

Wire Cages

The storage and bathroom sections of your local hardware mega-mart have many rubber-coated wire baskets and cages that can be used for holding your projector. Just secure the cage to the ceiling and set your projector in the cage. This solution offers easy removal of the projector for other uses such as home entertainment.

Brackets

With a little effort you can build a metal bracket to house your projector. The bracket would be permanently secured to your gaming area ceiling. The projector could be secured or removed with, thumb-screws, wing nuts, or latches. This solution may be perfect for projectors that don't have threaded mounting holes.

Ceiling Mounted Shelves

If you plan to employ the use of a mirror (see below) a simple and secure method of suspending your projector is to use a ceiling mounted shelf. They are commercially available at your local hardware store, or you could build your own with little effort. This solution offers the best combination of stability and ease of projector removal.

Using A Mirror

There are a few good reasons for using a mirror in your setup. Projector manufacturers usually don't recommend operating a projector outside of a 30° angle. This would certainly include pointing the projector directly down. It may interfere with heat dissipation and bulb life. Getting enough distance between the projector and the tabletop can often be a problem. Finally, mounting a projector perpendicular to the ceiling can be challenging.

By mounting a mirror at roughly a 45° angle and reflecting the projected image, you solve these problems, but as usual, there are tradeoffs. Mirrors can cause loss of brightness or image distortion. You'll also have to devise a safe and adjustable way to mount your mirror. Good luck!
