1. Roof Bevels Using Steel Square

2. Creeper Edge Bevel using Steel Square

3. Creeper Edge Bevel using Steel Square
Using our Knowledge of Similar Triangles
If we reduce all sides of the Triangle by the same ratio the angles formed will be the same

4. Creeper Edge Bevel using Steel Square
Therefore we need to reduce the full scale triangle to fit the steel square above

5. Creep Edge Bevel using Steel Square
Using our Knowledge of Similar Triangle
If we reduce it by a factor of 6 we have the triangle above left

6. Creep Edge Bevel using Steel Square
Using our Knowledge of Similar Triangle
If we reduce it by a factor of 6 we have the triangle above left

7. Creep Edge Bevel using Steel Square
In this case we
We are after this
angle
It doesn’t matter which blade of the square you transfer the measurement to so long as you remember the location of the angle you are after.

8. Creep Edge Bevel using Steel Square
We are after this
angle
If we place the measurements on the other blades
NOTE – Do not confuse this with the purlin edge bevel as it is not the same

9. Purlin Edge Bevel using Steel Square

10. Purlin Edge Bevel using Steel Square
Using our Knowledge of Similar Triangle

11. Purlin Edge Bevel using Steel Square
Using our Knowledge of Similar Triangle
If we reduce it by a factor of 6 we have the triangle above left

12. Purlin Edge Bevel using Steel Square
In this case we
We are after this
angle
.Remember it is important to keep track of the angle you want.
It is easy to confuse this with the creeper edge bevel

13. Creeper & Purlin Edge Bevel using Steel Square
I have always found it less confusing if the angles are put on the square as you see it

14. Hip Edge Bevel using Steel Square
From our previous work we developed the above dimensions
We need to reduce the triangle to fit on the steel square
Say Divide by 9

15. Hip Edge Bevel using Steel Square
From our previous work we developed the above dimensions
We need to reduce the triangle to fit on the steel square
Say Divide by 9

16. Hip Edge Bevel using Steel Square
Remember to Keep Track of the required angle
