Q: There are different types of polyurethane, including oil-based, water-based, and other synthetic mixes. Each type has different characteristics, so think about where your wood is located and how it will be treated in the future to pick the right product.  For example, oil-based poly will stand up better to the elements outdoors but it takes much longer to dry and cure than water-based products. Water-based poly won't last quite as long outdoors but can be washed out of tools easily. When picking out a product, you also need to decide between a glossy and matte finished surface. Place the wood on a surface that can get covered in polyurethane. Either brush the polyurethane onto the surface of the wood or soak a clean rag with polyurethane and then smooth it around the face of the wood.  Polyurethane is self-leveling because it is thin enough to spread out on its own. This means that you should not have to worry too much about achieving an even coat. Make sure to use extra polyurethane for the end grain because this is the most absorbent part of the wood. The end grain is the exposed, cut part of wood on the end of the piece. Use long strokes with a clean brush or rag to spread out the polyurethane. Work from one side to the other, trying to keep the distribution of polyurethane on the surface of the wood equal and smooth.  A rag with wipe-on polyurethane is the easiest method. Wear gloves during this entire procedure to avoid staining your hands. Use fine 400 grit sandpaper to rub down the entire surface to eliminate imperfections. You don't need to push hard but be sure to lightly sand the entire surface. After sanding, wipe down the surface with a rag in order to remove any dust you have created. Apply several coats of polyurethane to the surface of the wood, waiting for each coat to dry completely in between applications. Sand between coats to smooth out any uneven areas.  Keep an eye out for any polyurethane drips, and smooth them out with your brush or rag to avoid a bumpy finish. Drying time varies, so make sure you read your polyurethane's instructions and keep an eye on the ambient temperature and humidity as well.
A: Choose a polyurethane product that works for your project. Apply the polyurethane onto the wood with a brush or rag. Cover the entire surface with a smooth coat. Sand between coats of polyurethane. Apply multiple coats of polyurethane to achieve your desired finish.

Q: A club must be active in order to be successful! Make sure you meet regularly, whether that’s five days a week or once a month. Encourage every member to attend the meetings. It’s also a good idea to create a clear agenda for each meeting so that you stay on track and complete any tasks or goals you create. Be sure to give every member an equal opportunity to speak during meetings. You may also want to assign each member small tasks to help them feel involved and invested in the club. Being part of a club means feeling included! It’s a good idea to send out a brief synopsis of each meeting to members who aren’t able to make it. Or, you could post updates on your club forum or social media page. You could even create a weekly or monthly newsletter that updates members on new developments. Encourage discussion between members outside of meetings through phone, email, forums, and social media. Ask your members to advertise the club to their family, friends, classmates, and coworkers. Word of mouth is a great way to find new members! Post or pass out flyers that advertise your club around your community. Be sure to include the date, time, and location of the next meeting or your contact information so people can learn more.  You can also continue to post ads on classified and social media sites to find people who are interested in joining the club.
A: Host meetings on a regular basis. Stay in touch with the club members. Continue to recruit new members.

Q: Draw a line of hot glue around the clear, plastic circle at the center of a CD. Quickly press the top of the wooden spool into it. Make sure that it is centered. Repeat this step for the other three CDs.  You can use old, scratched up CDs or blank ones. Hot glue sets up quickly, so work one spool and CD at a time. The button needs to be big enough to cover the hole in the middle of the CD. Use a standard 2- or 4-hole button, not a shank button with a loop on the end. The button will cover the hole and keep the wheels in place. If you can't find any buttons, cut circles out of thin cardboard, and use those instead. Slide two rubber bands onto your first wheel so that they make an X shape on the front. Repeat this step for the other three wheels. This will give your wheels some traction. The rubber bands should be wrapped tightly around the wheels. You may need to wrap them more than once. These will go between the wheels and the cardboard tube. Place the wheels onto the ends of the dowels. Make sure that the cardboard tube is centered, then measure the gap between the spool and the cardboard tube. Cut a straw down to fit those measurements. You will need four pieces total.  Your first/front set of straws should be about 1-inch (2.54-centimeter) long. Your second/back set of straws should be about 2¼-inch (5.71-centimeter) long. You can use plastic or paper straws. Consider using a color that matches your car. Take the wheels off of the dowels first. Place the short stoppers onto the short dowel, and the long stoppers onto the long dowel. Place the wheels back onto the dowels and test the fit. If the stoppers are too long, take everything off and trim them down again. Once you are happy with the fit, take the wheels off and add a drop of white craft glue into each spool. Place the wheels back onto the axles, and let the glue dry. The wheels should fit snugly onto the axles. If they are too loose, wrap some masking tape around the end of the dowel to thicken it.
A:
Hot glue a  1-inch (2.54-centimeter) wooden spool to the back of each CD. Hot glue a button to the front of each CD. Wrap some rubber bands around the wheels. Cut some straws down to make the stoppers. Add the stoppers between the wheels and the cardboard tube. Attach the wheels.
