Shop Project/Cuts and Joins

 

-first step is the ‘concept sketch’, think about what you want to make

Consider:

-what material will you be using (in our cae probably .5 inch plywood)

-what function do you need your object to perform (if for instance it is going to hold books…how big are the books, what depth of shelf for instance will be needed for a binder, a sketch book, etc)

-what space is your build object going in to (if it needs to be sitting on or below your desk, then you need to take the dimensions of your desk into account)

-add dimensions /measurements to your concept sketch

-make a cut list of all the pieces that will be needed and their dimensions (the shelf below has a double walled construction which your objects won’t have…but it gives a general idea)

top 12 x 16

bottom 12 x16

sides (have to consider widtly of ply take 1/2 inch off sides and also depth

17 x 11.5 ”

Back 16 x 17

shelf,

-make a pattern for how these will be laid out on on a sheet of plywood. Remember when cutting the plywood you have to cut full length and full width of plywood.

 

 

Detials about joins: type of joint: butt joint

the shelf slides in but has a support piece

 

Layout for how you are going to cut it out of plywood, maximize plywood material.

 

Method of construction/attachment

Glue,  then brad nail from nail gun, then screw for greater strength

Types of Joins

Butt Joint (you see the end grain), Miter joint, 45 degree angle,  (you just see a line, and there is more surface contact area, so it is stronger)

The more you increase surface area with shoulder joints, dovetails, angles, etc. the more you increase the strength.

Other types of joins: Dowel, biscuit, Rabbett joint
