Roof Bevels Using Steel Square

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. Creeper 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. Creeper 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. Creeper 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. Creeper 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. Creeper 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

10. Purlin Edge Bevel using Steel Square

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

12. 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

13. 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

14. 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

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

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

17. Hip Edge Bevel using Steel Square Remember to Keep Track ofthe required angle
