1. Sand the tractor body as needed.
2. Using a toothpick, apply wood glue to the bottom ½ inch of one of the smoke stacks. Make sure the holes in the top of the tractor are clear and gently push and twist smoke stack into one of the holes. Repeat with the second smoke stack and make one smoke stack a little higher than the other. If the smokestack holes on your tractor are a little too big, just add some extra glue so that when you insert and twist the smokestack, the glue comes all the way to the top of the hole around the smokestack. Wipe away any extra glue.
3. Using a toothpick, put wood glue inside of the hole on one large wheel. Make sure the glue covers all of the inside of the hole. Then gently push and twist one of the axles into the hole until the end of the axle sticks out a little on the outside of the wheel. Wipe off any excess glue. Then, using NO GLUE, hold the axle and gently push the other big wheel onto the axle. Do not glue it yet! This helps the glue on the other wheel to dry with the axle straight. Roll the wheels gently to make sure the glued wheel rolls straight up and down. Tip or adjust the glued wheel if it seems a little off.
4. Repeat this process with one of the small wheels. But with the small wheels, the axel should be flush with the outside of the wheel.
5. Set the wheels aside to dry for at least two hours.
6. Use your imagination to paint all parts of your tractor with colors to make it unique and fun. Don’t let the paint get into the holes of the last two wheels to make sure the glue can stick to the wood.
7. Once the paint is dry, check the wheel holes on the sides of the tractor to make sure they are clear to insert the axle. If there is paint or small pieces of wood that block the hole, use the tip of a knife and twist in the hole to clear it out.
8. Slide the large (unglued) wheel off of the axle and insert the axle into the hole in the side of the tractor that is highest from the bottom of the tractor.
9. Using a toothpick, insert glue all around the hole in the remaining large wheel. Make sure the glue covers all of the inside of the hole.
10. Hold the tractor, wheel, and axle in one hand. Make sure the axle is pushed all the way through the hole. Using your other hand, gently push and twist the large wheel onto the axle until the axle sticks out just a little on the outside of the wheel. Don’t let this wheel or glue touch the side of the tractor until the glue has dried. Wipe away excess glue. Roll the wheel gently to make sure it is on straight. Tip or adjust the wheel if needed.
11. Using the same process, attach the small wheel to the tractor into the hole that is closer to the bottom of the tractor. But with the small wheels, the axel should be flush with the outside of the wheel.
12. Once both wheels are attached, gently roll the tractor a few inches to make sure the wheels roll smoothly.
13. Set the tractor aside and let the glue dry for about two hours.
14. Once the glue has dried, glue the flywheel to the side of the tractor.
15. Touch up paint as needed.
