STEP BY STEP GUIDE

STEP 1

Select two straight, knot-free sections of timber from 95mm x 20mm stock.
Measure 440mm from one end using a steel rule.
Use a square and a sharp pencil to square a line all round.
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 20mm from one end and mark the shoulder line, then mark the next line 20mm parallel to that.
Use a marking gauge to scribe 6mm down from the face.
Make the shoulder cut using a bench hook to hold the timber and a tenon saw.
Hold the timber in a vice and carefully chisel out the housings using a 19mm bevel edged chisel.
