PRACTICE SAW STOOL STEP BY STEP INSTRUCTIONS
These instructions should only be used in conjunction with the appropriate
plans
This job is a practice run for the Saw Stool Exercise. While it is not assessed
you will not be allowed to progress to the Saw Stool Exercise until you have
reached an acceptable level of competence in this practice job.
Step 1
For this job you will be given the following materials: - 1/90 x 40 Pine - 300mm long, 2/70 x
30 Pine – 300mm long, 1/250 x 200 x 12mm Ply

Step 2
Start by setting out the top of the Saw Stool. The legs are positioned 150mm from the end
of the top.
Note: This job has several angle and compound cuts that you will need to make however
they are all the same angle, 4:1 or 1:4. e.g. 1=50mm and 4 =200mm. You should mark this
out on a separate piece of scrap timber and keep it as a reference for the duration of the
job. Once set out you can use a Sliding Bevel to transfer the angle to your job.

Step 3
From the 150mm mark, mark the angle so it angles back towards the end of the Saw Stool
top.
Step 4
Next take one of the leg members and align it with the angle on the right hand side of the
line.

Step 5
Then mark the right hand bottom corner.
Step 6
From this mark square a line back up to the top of the Saw Stool Top.
Step 7
Square these lines across the top of the saw Stool Top.

Step 8
Mark a depth of 5mm on the top and bottom of the Saw Stool Top.
Step 9
Cut down the inside of the lines with a Tenon Saw, make a couple of relief cuts in between
and chisel out the waste.
Step 10
The other side of the Saw Stool Top is set out the same.

Step 11
Now you need to cut the tops to the legs of the
Saw Stool. Start 5-10mm from the end of the leg
and mark the 4:1 4:1 angle across the face of the
timber.
Step 12
Then continue the angle across the edge of
the leg.
Step 13
The next angle on the back face
should be in the same direction as the
one on the opposite face.

Version 1 June 2011
Step 14
The next angle should join the lines back
together.
Step 15
With the marks joining up you can make the cut using a Panel Saw
Step 16
Now you need to make an opposite of the leg that you just cut. The best way to do this is to
stand the piece that you just cut beside the one you are going to cut. Then mark the angle
on the face of the timber in the opposite direction to the one that you have already cut.

Version 1 June 2011
Step 17
The angles to the faces should be the same as the ones that you cut previously.
Step 20
Continue this around the leg, edges opposite faces the same.

Step 21
Once marked you can cut the second
piece, You should end up with a pair
of legs.
Step 22
Now that the first angles are cut you
need to mark out and cut a checkout
in the top of the legs so they fit into
the recess in the Saw Stool Top and
also fits under the Top to give it
additional support.
First, on the lower side of the leg cut,
mark a line 10mm from the edge.

Version 1 June 2011
Step 23
From the 10mm mark, the 1:4 angle down the edge
of the leg.
Step 24
Measure down this line 40mm, the thickness of
the top, and from this point mark the same
angle as the top of the leg
P a g e | 11
Version 1 June 2011
Step 25
Across the face transfer the same
angle as is at the top of the leg.
Step 26
On the back edge of the leg you can again transfer the same
angle as at the top of the leg and use the 1:4 angle from the
10mm mark on the top to complete the set out.

Version 1 June 2011
Step 27
Cut to the lines, removing the high point of the
leg.
Step 28
Repeat this process on the other second leg
remembering that the opposites will need to
be set out from the other side of the leg.
Step 29
Next you need to remove the front section of
the leg top to allow it to fit into the squared of
section on the saw Stool Top.
On the long edge of the leg, continue the angle
that you cut the leg across to the opposite face
of the leg.

Version 1 June 2011
From where this mark meets the face use the 1:4 angle to mark the area that needs to be
removed.
Step 30
Remove the timber. This can be cut or planed until it
fits tightly into the recess in the Saw Stool Top.

Step 31
Now the legs can be screwed onto the Saw Stool Top.
Use 3 50-65mm screws. The screws should be spaced evenly both vertically and
horizontally.
Step 32
Next you need to prepare the leg stiffeners for placement. As they are to be positioned tight
up under the Saw Stool Top the Ply needs to be cut at the 4:1 angle.
P a g e | 15
Version 1 June 2011
Step 33
Next place the ply in its position and mark
the angle required. When you do this you
need to ensure that the legs are in the
correct position. This can be done by
positioning a pre-cut template between the
legs to hold them in position. Ask you
facilitator for this template.
Step 34
Cut and plane the ply to the lines then screw
the ply to the legs with 3/25mm screw
evenly spaced down each side. Ensure that
the Ply is tight up against the Saw Stool Top.
