Traditional Wooden Flask
Tuesday 19 July 2011
Nick Arnull creates this traditional wooden vase with inset panels which uses salvaged pieces of wood and timber offcuts

1.The completed traditional wooden flask
This is quite a simple project but it does require some thought and particular attention needs to be made regarding accurate multiple chucking. Flasks are often made from one piece of timber but I decided to make mine using inset panels. This would allow me to create balance and contrast in the design.
Too often I see items made using one colour of timber and find them bland and uninteresting. You can use figured timber to accent areas of a design to make it more visually dynamic. However, if doing this, I recommend keeping the design simple and letting the wood speak for itself, as this will create a stronger design.
Tools used: Side-cut box scraper, 10mm (3/8in) point tool, 10mm (3/8in) round skew chisel, 6mm (1/4in) parting tool, 10mm (3/8in) fingernail spindle gouge, 12mm (1/2in fingernail spindle gouge and 10mm (3/8in) square-grind bowl gouge
Turning the body
Step 1
Begin by selecting your blank and accurately marking the centres - as per the drawing - then drill a 15mm (9/16in) hole in the top, which will become your flask top. Next, using a drill bit to match your 50mm (2in) chuck jaws, drill a shallow hole into one face of the blank. If you are using a drill press, remember to clamp larger pieces to the table or accidents can potentially occur
Step 2
Mount the blank onto the lathe using the hole made by the 50mm (2in) drill bit - this is your first chucking method. Draw the maximum diameter circle you can and then another 10mm (3/8in) inside this which will be your cutting guide. Create a second 50mm (2in) dovetail recess in the middle - this will be used later in the project - but must be parallel to the opposite face
Step 3
Mount the blank between centres and begin to work towards the line marked earlier using a 12mm (1/2in) fingernail spindle gouge. This task is easier if the lathe is running at a good rate. Once the line disappears, the waste wood will be removed and, all being well, you will have a circle. Take your time and check your progress regularly
Step 4
Once the main body has been turned, create two parallel spigots at each end of the blank - this is best done using a 6mm (1/4in) parting tool
Step 5
Using a freshly sharpened 10mm (3/8in) spindle gouge, refine the shape but take only the lightest of cuts
Step 6
With the lathe stationary, you can now sand the turned edges
Step 7
Turn and create the outside shape of the neck so that it is 40mm (1 5/8in) long
Step 8
With the outside shape completed remove the piece from between centres and mount the spigot into the chuck using the tailstock centre to align the piece accurately. With the tailstock removed, soften the opening and then turn a shoulder into the top of the neck using a square-ended box scraper. Take care at this stage, then you can sand the neck
Step 9
Once more, change the chucking method and turn the piece across the bed of the lathe. Next, mount it using the 50mm (2in) dovetail recess created earlier, which will allow you to true the two faces/sides of the flask
Step 10
Now mark a 100mm (4in) diameter and create a parallel opening - this is where the inset panels will be fitted. It also creates another chucking method
Step 11
Reduce the centre so it will allow the chuck jaws adequate clearance later in the project - I used a 10mm (3/8in) square-grind bowl gouge. Now reverse chuck and repeat on the second face/side
Step 12
With the two face/sides complete it is time to change chucking again, so remove the piece from the chuck and mount between centres using a tapered scrap wood friction drive. Using a live centre in the tailstock, mark 8mm (5/16in) from the bottom of the flask; this defines the final length of the flask
Step 13
Carefully shape and refine the bead at the bottom of the flask
Step 14
Carefully sand, seal and lacquer the flask, then allow to dry
Step 15
With the piece finished you can now detail the underside of the foot, remove the waste material, and then finish by hand
Step 16
Final chucking for the body of the flask allows the removal of the centre - this will be saved for use another time - and will make the flask hollow. If you choose not to do this then your flask will be a little heavier than mine. Part in from one side then reverse chuck and repeat, taking care as you do so
Turning the panels
Step 17
Using double-sided tape, begin by centring and mounting your blank - this needs to be done on what will become the finished face. You then need to create a 50mm (2in) dovetail recess, before creating a spigot to match the flask opening. I found I needed to have the tailstock in place in order to keep the blank centred
Step 18
Reverse chuck the blank then make round and dome the surface, leaving a 3mm (1/8in) square edge. You can then sand
and finish
Turning the stopper
Step 19
I found it easiest to make the bottle stopper in two parts and then glue it together. Begin by creating the bung section - the bit that fits into the neck of the flask at the top - then create a spigot at one end to fit into a drilled hole in the decorative top section, which will simply be glued in place when both parts are complete. Take a piece of English sycamore (Acer pseudoplatanus) and mount it between centres, checking the fit constantly. You can then sand and finish
The decorative top
Step 20
Drill a hole into the blank then mount it between centres using a standard 60 degree live centre - this will sit into the hole that has been drilled - then turn to the shape required. The parallel section sits in the opening at the top of the flask's neck
Step 21
Once you are happy with the shape of the bung, sand and finish, then glue the two parts together before allowing to dry. The traditional wooden flask project is now complete
