Victorian Door Knockers

Thursday 11 November 2010

Paul Loseby takes inspiration from the Victorian era and turns two matching door knockers from a piece of oak

1.The completed Victorian door knocker

The inspiration for this article came from the TV programme 'Victorian Farm' and in particular when they renovated a blacksmith's forge. The presenters made one of the old Victorian door knockers out of steel and I thought that a similar thing could be made out of oak (Quercus robur) using some simple techniques. I didn't manage a lion's head on the knocker but there is no reason why this piece can't be carved and decorated. In addition to the turning tools pictured below, you will also need a 150 x 25mm (6 x 1in) round blank of English oak and an 89 x 89 x 230mm (3 1/2 x 3 1/2 x 9in) piece of the same timber, plus a roll of gaffer tape.

Tools used: 3mm (1/8in) parting tool, 12mm (1/2in) skew chisel, 10mm (3/8in) spindle gouge and 15mm (5/8in) bowl gouge with double bevel

Step 1

The first step is to take your oak blank and with a 'V' shape, mark the edge of the large piece to ensure later alignment. Use a bandsaw to rip this piece lengthways, into three sections, the cuts being 32mm (1 1/4in) from one edge and a further 32mm (1 1/4in) from that same side. Glue these pieces back together by inserting newspaper between each section. Spread the PVA glue onto the wood evenly and to each of the four edges. The newspaper is then laid onto that glue and then a further application of adhesive is spread on this side of the newspaper before putting the next section of wood back onto the piece. Repeat this step for the next joint

Step 2

Clamp the piece together, and have two clamps on one side with a third facing in the opposite direction to ensure a thorough grip. Set the piece aside to cure and move on to the round blank that will form the ring

Step 3

Drill a suitable sized hole in the centre of the round blank for your screw chuck and fasten on. Using a bowl gouge, trim the diameter to 125mm (5in). Mark a circle at 108mm (4 1/4in) on the face of the wood. The piece is purposely too thick and so on the face side, make a spigot for your scroll jaw chuck. This centre piece, with Velcro attached, will make a sanding disc. Using a gouge, roll the front edge over and continue round and in. You are trying to create a half ring between the edge of the piece and the 104mm (4 1/4in) mark

Step 4

Now start to roll the left edge nearest the headstock taking the roll as far as possible

Step 5

Sand the ring as far as possible, then fasten pieces of gaffer tape - or equivalent - so that it holds the finished part of the rim to the centre section. Turn the piece around and fasten the spigot into your chuck on the lathe. You can now finish this side of the ring, but take care when breaking through. The gaffer tape will stop the ring falling off and getting damaged against the headstock and chuck. Flatten the face if you are going to make this a sanding disc. Sand and shape the inside of the ring, going through the necessary grits until you achieve the desired finish

Step 6

Back to the glued-up piece. Trim the length to 180mm (7in) but ensure, by cutting, that each end is square and flat. Glue a packing piece to each end and let it dry. We now need to drill two holes. These should be slightly larger than the diameter of the ring and have centres, midway along the length, level with each other and 21mm (7/8in) out from the paper joint in the middle of the piece

Step 7

After rounding off the blank, we need to create a sphere with the widest diameter level with the centre of the holes. Use callipers to measure the diameter of the piece and then mark this measurement lengthways, using the centre of the holes as the centre point of the measurement. Using a 3mm (1/8in) parting tool, reduce the diameter at those two outside lines to 25mm (1in)

Step 8

Turn the sphere section as round as possible. Whilst doing this, you will gradually be peeling back the edges of the holes - this is intentional. I tend to use a skew but you can use whichever tool you feel comfortable with

Step 9

Part down at the sides of the sphere you have created and allow the sphere to be further rounded, until you are left with two beads at each side. On the outer side of each set of beads, turn half a cove and part down to about 25mm (1in). Then sand through the grits, as necessary

Step 10

Part each end as narrow as possible and then remove from the lathe by sawing the ends

Step 11

Part the newspaper joints by using a Stanley knife blade and a small hammer. Tap a little here and a little there rather than just hitting one place. You do need to be gentle but you will be surprised as to how strong these joints are

Step 12

You now have two halves with one of these split for putting the uncut ring into the predrilled hole. For the piece on the left, we will saw the ring in two and join with glue and piano wire or needle

Step 13

With Velcro glued to the centre of the ring that you cut earlier, using loop-backed abrasive, sand and clean the joints. Changing the paper as necessary, sand each end of the piece

Step 14

Drill a screw hole through the piece for the uncut ring and screw to the door. Pass the ring through the centre 'hole' and glue back the outer piece to contain the ring. You then just need to lay the ring over the open hole and first, ensuring that there is free movement, re-glue the front of the ring, sanding and blending as necessary

Step 15

For the alternative method, take the solid piece with the drilled hole in, and decorate and finish as you wish. There are no other glue joints on this piece so we need to split the ring rather than this piece. Using a fine tooth saw, cut through the ring so that you have two half circles

Step 16

Drill the centre of each end - four in total - with as fine a drill bit as you have. This should be exactly in the centre but 0.5mm either way should not make too much difference. Glue a short length of piano wire or a short sewing needle into both ends of one piece. Because the ring has been cut in two, we need to hide the bottom joint. With the spare piece of timber that was cut off, drill a hole through it, slightly bigger than the diameter of the ring - so as to allow for the curve in the ring. Then just turn a small sphere or any other object that you prefer

Step 17

Slide one half of the ring through the hole in the main piece and slide the small sphere over the other half. With your preferred adhesive glue the ends and then fit together, the piano wire seating in the hole in the other half. Set aside to dry but with the joints at each side rather than in position through the hole and sphere

Step 18

When the adhesive has dried, apply epoxy resin over the joint that will go through the sphere. You need sufficient glue to stick the sphere to the ring so that this is the 'knocking' bit at the bottom. The ring must be allowed to move freely in the main section of the knocker

Glossary Rollover a term to view its definition

  • Bowl Gouge
     

    Bowl Gouge

    Bowl Gouge

    A cutting tool with a deep flute and a heavy cross-section. These are normally made from round bars and the flute is milled out. The round bar fits into the handle thus giving the tool a great deal of strength to enable it to overhang the toolrest a long way in order to hollow out deep bowls. Its primary function is for faceplate - or bowl turning - but it can also be used in spindle work. The bevel angle is ground to suit the user but is anything between 40 degrees and 80 degrees. Traditionally, bowl gouges are ground straight across, but many turners prefer to grind the wings back. There are many terms for a swept back bowl gouge - fingernail grind, O'Donnell grind, Irish grind, Ellsworth grind, lady's finger - to name a few. There may be subtle differences in these grinds, but generically they are all bowl gouge grinds where the wings have been ground back.

     
  • Parting Tool
     

    Parting Tool

    Parting Tool

    As the picture shows, there are several different types of parting tool - three of which are shown here. On the left is a narrow (3mm) parting tool which is very useful when parting work where the least amount of grain mismatch is desirable, for example when parting the lid from the base in box making. The middle tool is a straight sided, standard parting tool and the one on the right is a diamond parting tool where the widest part of the tool is at the cutting edge. This can be advantageous when cutting deep grooves because it means less of the tool is rubbing on the sides of the groove. Parting tools primary task is to part wood off in spindle work but they are also used to cut tenons or spigots and grooves. They can also be used to cut beads.

     
  • Skew Chisel
     

    Skew Chisel

    Skew Chisel

    An extremely useful tool but has a reputation for being difficult to control. Certainly you can get some nasty catches with it but it is worth mastering. It is used mainly in spindle work and produces a very fine finish from the tool, requiring little, if any sanding. Planing cuts, peeling cuts and slicing cuts can be made with the skew as well as turning beads, coves and 'V' cuts. Typically, the cutting edge is ground at 60 degrees to the axis of the tool - hence the term 'skew' and the tool has two bevels whose inclusive angle is anywhere between 25 and 45 degrees. Skews are now made in three styles - rectangular section, oval section and rolled edge section.

     
  • Spindle Gouge
     

    Spindle Gouge

    Spindle Gouge

    Modern day spindle gouges are made in the same way as bowl gouges - from a round bar of M2 high speed steel with the flute milled out. The flute is shallower and more open than that of a bowl gouge. Traditionally spindles gouges were forged from a flat, rectangular sectioned bar and some manufacturers have started making a modern day version of this, commonly known as the Continental Style spindle gouge. Like their name suggests, spindle gouges are used to cut details such as beads, coves and fillets on spindle work.

     
  • Bandsaw
     

    Bandsaw

    Bandsaw

    Bandsaws have a relatively small footprint and are often the first choice of machine as they can perform a variety of operations. A good quality machine accurately adjusted, with sharp blades can do rip cutting including deep ripping or even thick veneers, it can cut tenons for joints and various awkward shapes including tight curves if a narrow blade is fitted. For solid timber it is usual to fit skip tooth blades, these have a gap between each tooth thus allowing waste to clear quickly. For thin ply or MDF a fine tooth blade is needed.

     
  • Headstock
     

    Headstock

    Headstock

    This is normally made from cast iron or fabricated in steel and houses the lathe's spindle and one set of pulleys. (The corresponding set of pulleys it attached to the motor's spindle, which in some models can also be incorporated within the headstock) The spindle is supported by two or more bearings at the front and back of the headstock. Some lathes have their headstock fixed rigidly to the bed; others are designed to swivel and/or move along the bed. Rigidly fixed headstocks have their spindles in line with the bed and the diameter of work they are capable of holding is limited by the height of the spindle above the bed. Lathes whose headstock swivel are not limited in this way.

     
  • Cove
     

    Cove

    Cove

    A concave curve found on the circumference of spindle work

     
  • Screw Chuck
     

    Screw Chuck

    Screw Chuck

    This can be described as a small faceplate that has a single screw centrally located in it. Two types are common, The first makes use of a standard mild steel screw (the Record Power screw chuck is a good example of this) and the second is a parallel sided machined screw that usually fits into the jaws of a scroll chuck

     
  • Spigot
     

    Spigot

    Spigot

    A parallel or dovetail shaped projection protruding from the end of a piece of wood, suitable for being held in the jaws of a chuck in compression mode. Sometimes a spigot is called a tenon

     

handy hints

1. With any unwanted flat discs of 25mm (1in) or more thickness, fasten some Velcro backing sheet to both front face and edge. You can then use the front for normal sanding and the edge for concave curves

health & safety

Here, you are going to be paper gluing joints together. Sufficient time needs to be allowed for the glue to cure, and you also need to use solid timber packing pieces at the end of the block before turning between centres. The last thing you want is for the joints to break whilst you are spinning the block at 2,000rpm. Oak does not normally create breathing problems but old oak does generate a lot of dust, and if it does get onto your lungs, it does not just evaporate. Therefore, it is essential to use a suitable respirator or at the very least, a good quality face mask.
