STEP BY STEP GUIDE

STEP 1

Select a straight, knot-free section of timber from 45mm x 30mm stock
Measure 155mm from one end using a steel rule
Use a square and a sharp pencil to square a line all round (You can use a marking knife to improve the accuracy of your work-ask your tutor how this works)
Secure the timber on a bench hook and use a tenon saw to cut to length. Make sure you saw on the waste side of the line as you have been shown in this video

STEP 2

Measure 50mm from one end and mark the shoulder line as shown
Use a marking gauge to scribe the cheek line
Hold the timber in a vice and carefully make the cheek cuts.
Make the shoulder cut using a bench hook to hold the timber

STEP 3

Mark a centre line on the cheek

STEP 4

Cut a second piece of 45mm x 30mm timber 200mm long
Mark a centre line as shown

STEP 5

Put the two pieces of timber together as shown with the centre lines lined up
Mark a line on either side of the top section as shown

STEP 6

Use a pencil and square to mark lines as shown at (A)
Use a marking gauge to scribe a line (B) 15mm down as shown

STEP 7

Carefully cut the shoulder lines with a suitable saw
Use a sharp chisel to cut away the waste
Clean up the joint with your chisel and check that the two halves fit snuggly

STEP 8

Once you have a good fit, mark the centre of the halving joint as shown
Use a combination-type countersink bit to drill a hole for the countersunk screw you will use to secure the joint

STEP 9

Apply glue to the joint and assemble
Secure the joint with a suitable countersunk screw
Allow enough time for the glue to dry before moving on to step 10

STEP 10

Remove the waste with a saw and sharp plane
Remove any pencil marks
Clean off any glue residue and lightly sand the finished assembly
Remove the arris (sharp edges)
Show the finished piece to your tutor who will help you to assess your work and complete the sign off sheet for this task
