Obtuse mitre was correctly bisected
Architrave mitres tight without a gap exceeding 1mm plus
The architrave margin is 8mm within +/- 3mm
Mouldings were securely fixed with nails punched below the surface.

Merit

All the pass criteria have been achieved
The architrave margin is 8mm within +/- 2mm
There were no bent nails.
The task was completed with only one hammer mark.

Distinction

STEP BY STEP GUIDE

STEP 1

Mark parallel off the studwork/wall at all the internal and external joint areas

STEP 2

Bisecting the angle. Line up the front and back lines with the blade of a sliding bevel, and mark a line on the floor through them. This is the bisected angle used to mitre the skirting. The sliding bevel can now be set to this angle.

STEP 3

Complete the bisecting process for all the angles involved.

STEP 4

Always try and cut the longest sections of skirting first. This is because if it is cut incorrectly you can use the skirting for smaller pieces.
Place the skirting in the correct position
Mark the bisected angle vertically up the face of the skirting.
Then using your sliding bevel mark the mitres on the skirting, making sure they are the correct orientation.
Then cut.

STEP 5

Complete the above process for all the external mitres.
Fix the skirting back to the walls leaving them just proud, using either lost-head or oval nails, in pairs vertically. This helps reduce the cupping effect on larger softwood skirting.

STEP 6

Marking out for an internal scribe
Firstly take your bisected angle and mark the skirting up as if you were making an internal mitre.

STEP 7

Carefully cut along the internal mitre line.

STEP 8

Cut along the profile created by the internal mitre
The cut should be at the full angle,in this case 90 degrees.

STEP 9

Using the two methods described, complete the rest of the skirting jig.
Check all gaps are no larger than 1mm and that all nails are punched below the surface.

STEP 9

Mark a margin line 8mm in from the inside edge of the lining

STEP 10

place the lengths of architrave against the margin line and tack into position.

STEP 11

Using the same method as skirting, bisect the angle and set your sliding bevel to that angle.
Mark up the architrave ready for the cut.
Cut and fix in place, remembering to leave the nails proud ready for punching below the surface.

STEP 12

Place a length of architrave upside down to the uprights and mark it off for its overall length.
Using your sliding bevel mark on the angle to be cut

STEP 13

Cut to the line and fix in position.
Repeat step 12 for the final piece and fix in position.
Punch all nails below the surface.
