Defined; In a woodworking context a dowel is a loose piece of wood cut so the grain runs down it's length, which is usually round in section, often fluted and is inserted in matching, opposed holes in pieces of wood to be joined or dry aligned. If both ends are glued it forms a joint, if one end only is glued dowels can be used for location of pieces in knock down situations.

The use of dowels as a joining method for woodwork goes back in antiquity to the earliest days of humankind's use of joined wooden structures. Dowels are found in early Egyptian and Chinese pieces which have survived centuries.

Why Doweling?

Doweling in woodwork has survived and flourished for the best of all reasons, simplicity and, when done properly, unrivalled strength. An array of dowels of good quality, closely sized and accurately set with a quality adhesive performs very well in both sheet joining and post and rail type structures.

The majority of doweling jigs on the market have a self contained clamp whereas the Joint Genie requires clamps as an accessory. The magic of the joint Genie is that it needs only two adjacent accurately and consistently machined faces to work from. This opens up doweling to waney edge work which cannot be achieved with clamp style jigs.

Why Joint Genie?

The use of a jig to accurately space and position dowel holes is strongly advised for all doweling operations. If you have tried to pull together a joint made more or less by reckoning or from the use of dowel points you will likely be aware of the essential requirement for accuracy. Joint Genie provides this.

The bars and precision ground finger offsets, which are the core of the system, offer flexibility far more varied than is immediately obvious. You can replace the M6 set screw which holds the fingers to the bar with a length of threaded rod up to as long as you can obtain. This allows, for instance, ultra precise placement of dowel (or shelf pins) up to a metre in from the reference edge assuming you use metre lengths of threaded 'booker' rod.

Bars can be joined end to end, in T formations and the set screw which attaches the spacer fingers can be substituted with M6 threaded rod to allow extended hole offset spacing.

The bars are end drilled and tapped M6 which allows bars to be ganged up for long arrays of dowels.

Joint Genie jigs are British made.

Joint Genie Offers

  • The ability to work with both sheet and post & rail stock with ease.
  • Many joints performed in seconds.
  • Minimal markout other than marking reference faces.
  • A range of dowel sizes, 6,8 and 10mm.
  • Some bars with dual arrays.
  • Bars which can be joined end to end.
  • Bars which can be ganged side by side to quickly set multiple rows of side by side dowels.
  • Bars which can be arranged in T arrays for carcase work.

Doweling Best Practice

  • Use a jig which offers accuracies to the micro millimetre.
  • Work with stock which has a minimum of two adjacent faces accurately milled. (Alternatively fasten a temporary straight edge and work from that).
  • Carefully mark reference faces and always work from them.
  • As a readily breakable rule, design for half the length of dowels to be in each piece.
  • Use quality hardwood dowel (the standard in Australia is a very tough eucalypt called Tasmanian Oak).
  • Use fluted dowels to allow for distribution of the adhesive and allow squeeze out. Failure to do this can mean exploded joints due to clamp pressure on the trapped glue.
  • Drill a combined hole a little longer than the total dowel length i.e. just over half a dowel length in each piece.
  • Use a quality adhesive and attain the skill of using enough - neither too little or too much. See HERE for a slow cure hard cure PVA perfect for doweling.
  • Assuming you have a glue with some time before grabbing clamp up in stages to allow air to escape and any squeeze out to occur.
  • Where feasible test fit with a dry assembly. This can be scary with tight fitting dowels so may need to be skipped..
  • A brad point doweling bit cuts a cleaner hole in wood than a jobber bit which is optimised for metals and may tend to grain follow.
  • Seek out metric dowel. Be aware that 5/16 inch (7.94mm) dowel is often passed off as 8mm and 3/8 inch (9.53mm) as 10mm.
