In one sentence, describe what the following article is about: Always wear gloves and eye protection when working with contact cement. It might even be a good idea to don a respirator if you have sensitive airways. Since it contains potent chemicals, you'll want to limit direct exposure to the adhesive as much as possible. Short-sleeved or snug-fitting clothing is a must. You don't want to accidentally drag a sleeve through industry-grade adhesive! Contact cement is most often used in construction and industrial projects. Due to its involved application process, it isn't the best choice for arts and crafts or minor repair jobs. Instead, it's useful for activities like applying Formica to countertops. Contact cement emits flammable fumes which may be unsafe to breathe. Set up your materials outside, if possible. If you're confined to an indoor workshop, open a door or crack a couple of windows and keep a fan running to allow the fumes to escape. If your project is taking a while, take frequent breaks to limit your exposure to fumes. Spread a thin coat across the entire surface, being cautious evenly cover the edges, but not to let the cement overlap them. Contact cement only sticks to itself, so it will be necessary to apply it to both pieces. When the adhesive is sticky to the touch but doesn't rub off on your fingers, it will be ready for joining. Use the smallest amount of adhesive possible. Before you start brushing on the contact cement, clean both surfaces thoroughly. Contaminants on your project surface can affect your bond and create an uneven surface. Arrange a series of dowels or scrap wood across the bottom piece and set the other piece on top. This will allow you to make minute adjustments. Once you've got the pieces where you want them, slide the spacers out one by one. Spacers will come in handy when joining pieces with precise edges, such as countertops or laminate and substrate. The cement won't bond to the spacers because they don't have any adhesive on them. Go over the top piece with a roller, or tap it lightly all over with a rubber mallet or similar object. This will complete the bonding process and help form a stronger connectionno extended drying time required. If you don't have any other tools on hand, you can use a piece of lumber wrapped in a towel to flatten the top piece and work out bubbles and other inconsistencies. The heat of the iron will reactivate the cement, making it pliable again. Run the iron over the area that needs fixing for a few seconds until the pieces begin to lose their hold. Then, adjust them carefully by hand and leave them to dry. Keep the iron on a low-medium setting to avoid damaging either surface. Clean up accidental drips, streaks, and smudges using lacquer thinner.
Summary: Use the proper safety gear. Work in a well-ventilated space. Roll or brush the contact cement onto both pieces. Use spacers to help align your materials. Apply direct pressure to the joined pieces. Correct mistakes with a clothes iron.

In one sentence, describe what the following article is about: In standard tuning a really simple one of these is on the 12th fret, any string.
Summary: Set your guitar to the bridge pickup. Hold down any fret, on any string, this works best on natural harmonic notes. Choke up on your pick so there is only about a half or quarter centimeter showing. Pick the note, but barely brush your thumb across the string as you pick it (should be one motion). Put a nice vibrato on the note (optional).
