*Structure Building Jigs
A Jig is a gauge, pattern, or mold used as a guide to the form of a piece being made. They can be 2 dimensional or 3 dimensional. You do not have to use a jig but using a jig helps you build consistently.
ANY JIGS USED BY THE TEAM MUST BE BUILT BY THE TEAM
2 Dimensional Jigs
3 Dimensional Jigs
At some point you will want to assemble your two dimensional sections into a three dimensional structure. This can be done without the use of a jig by using carpenter’s squares, a steady hand and patience. You may also want to create a 3D jig to use in assembling your structure.
|The picture on the right shows a variety of materials that can be used to construct a 3D jig. You can use aluminum tubing or blocks of wood to assemble a jig.|
There are lots of options to choose from when creating a 3 dimensional jig. You may decide to make your own using materials such as those shown in the photograph. You should also visit hobby shops and home improvement centers and look for materials that can be used for a 3D jig with little or no modification. Hobby shops have plastic boxes and florist foam in various sizes. Home Improvement centers have blocks of wood in various sizes and shapes. Just remember that the team must create any jigs that you choose to use. This does not mean you cannot use something that you have purchased from the store as a jig. It does mean that if the thing you purchased requires modifications to use as a jig – then the team must make the modifications.
Final Notes on Construction Jigs
- You do not have to use a jig to construct a structure.
- Jigs should be true. If you want to end with a level structure then your jig has to start level.
- Any errors in the construction of your jig will magnify during the construction of your structure because no one is a perfect builder.
