How to Make a Trigger for a Crossbow:

• Use the wood chisel to cut a rectangle 1 inch wide by 1 1/2 inch through the crossbow stock (top to bottom) at the point you wish to mount the trigger
• Using the drill and 3/8-inch wood bit, drill a hole through the center of the round side of the hardwood cylinder
• Using the narrow blade wood saw for the rough cut and the chisel for finishing, cut notches for the bow string and trigger into the hardwood cylinder as shown in the drawing
• Using the drill and 3/8-inch wood bit, drill a hole through the sides of the crossbow stock to mount the trigger block as shown in the drawing. Slip one of the metal rods, 3/8 inch by 6 inches, through as the trigger block pivot
• Using the drill and 3/16 inch metal bit, drill two holes in each of the 3-inch long metal straps: one being 1/4 inch from one end, the second being 1 inch down from the first and both being in the center of the width of the straps. Using the 3/8-inch metal bit, drill a third hole 5/8 inch from the other end of the strap and centered
• Clamp the 5-inch strap of metal in the bench vise with the last 3/4 inch of one end held in the jaws. Bend the strap so the last 3/4 inch is 90 degrees to the rest of the strap
• Epoxy the remaining 3/8 inch metal rod to the 5-inch metal strap at a point no more than 1 1/2 inches back from the 90 degree bend and perpendicular to the length of the strap. Allow epoxy to harden completely. If you have access to welding equipment, welding this pivot arm would be better.
• Fit the angled end of the 5-inch trigger bar into the bottom of the trigger block (see drawing from step 4). Use this positioning to determine the best point to mount the smaller straps to the crossbow stock (using the wood screws) to allow the 3/8-inch holes cut in the straps to hold the trigger pivot out at a comfortable distance from the stock. When a string is pulling against the trigger block, the trigger bar must hold the block in place. To release the string (fire the crossbow), the archer will squeeze the trigger bar up (from a grip behind the trigger pivot) which will pull the trigger bar down and out of the trigger block notch. This must be a smooth and comfortable action for the archer to ensure the best results

How to Trigger Flashes on Professional Cameras:

• Assess the scene to determine what kind of flash will be appropriate to use. The type of flash means how big the flash needs to be and how far from the camera you want it. There is a link to a helpful table below. Another factor for your flash will be your ability to use camera equipment such as a tripod or an umbrella stand
• Lock the flash directly into the flash port of your camera. This technique is for the highest amount of mobility and is probably the easiest flash set up to pull off. All you need is you camera and the flash. When you take the picture, the flash will automatically trigger
• Attach a bracket to your camera to give your flash a little more height and distance from the lens. This technique has its advantages, but it also requires more equipment such as the bracket itself and a short cord that will attach the flash to the flash port on your camera. The flash will deploy automatically when you take the picture
• Hook the flash to your camera with a much longer cord and mount the flash independently. As you venture into more professional looking photos, the brightness and distance of the flash is going to vary depending on your subject. This technique will require a separate stand for your flash, a much longer cord to connect to your camera, and a tripod to stabilize the camera itself. Once again, the flash will automatically fire when you take the picture
• Connect your flash to the camera via a wireless system. This is essentially another variation of step four, only there are no cords involved to trip people up or to prohibit flash placement. This is good for high traffic areas or shoots with particularly odd environments. These wireless systems can be bought for various prices which may determine the quality of their performance
