OILSTONE CASE STEP BY STEP INSTRUCTIONS
These instructions should only be used in conjunction with the appropriate
plans
Step 1
You will be given a piece of of timber that should be around 600mm long, 70mm wide and
30mm thick. If you piece is not 70mm wide or 30mm thick you will need to plan it down to
these dimensions. The length will not matter at this stage.
Step 2

Next take the piece with the 12mm rebate and mark it out with a marking gauge so that you
can plane it down to the required thickness, 25mm.

Again using your Marking Gauge mark a 5mm Aris around the top of the top piece.

Step 11
Plane down to the lines in order to form the Aris.
Step 12
Using the Oilstone Blank supplied by you class facilitator, test your recesses to ensure that
you have a good fit.
The base should be tight but not too tight so that the Oilstone is held in place without
moving around in the Case but no so tight that you break the Stone getting it out.

The Top should be slightly looser so that is easy to get it on and off.
Completion
Sand the job so you remove all pencil marks, place your name on the bottom of one of the
recesses so that it will be covered by the stone later on and give it several coats of Shellac
with a light sand in between coats.
When you believe that you are finished complete a Self-Assessment Check on it and then
present the Self-Assessment Check and the job to you class facilitator for marking.
