SLED BUILDING

 

 

 

Mr. Holly, Industrial Arts instructor from Valley Middle School helped our class with the sled building project. Not only did he redesign the sled plans on a computer program, but he also pre-cut the lumber to size for us. He allowed us to use his workshop, tools, and provided us with some much appreciated assistance and supervision.

The handlebars were one of the first things assembled. They were then set aside to be attached to the bottom of the sled later.

Here, one of the groups is working with an uncle helper to begin one of the first steps on the sled. The bottom, or carriage of the sled was assembled after the handlebars.

Mr. Holly is tracing the pattern for the runners. On the original sled, the runners weren't curved up. We felt that the sled may dig into the snow when pulled. Mr. Holly made a template to use in order to assure the correct angle curve. We used treated lumber for the runners only. We felt that since they would be the parts in the most snow and needed more protection against warping or cracking.

It was very important to use appropriate tools to measure angles at which parts of the sled were attached. Various degrees of angles were used throughout the sled. Some 90º were important as well as less angles for braces on the side.

 

Check out the sled plan to see the different angles required to complete a sled.

 

The crossbar pieces provide support for the handles and upright boards of the sled. Sleds had to be built carefully and both sides needed to match up in order for the sled to be even and not crooked.

The bottom of the sled has been finished on this one. The crossbars were done first, giving more support for the next step.

Each group constructed the sled they were going to be racing. Much personal satisfaction and consideration was being taken during the building process.

The angled braces were then attached to the handlebars and bottom (carriage) of the sled.

They provide support for the sled, handlebars, and musher during use. Not to mention that without them, the sled wouldn't hold up.
