This jig will not only do centred dowelling, but it will dowel boards of different thicknesses to one reference face; the assembly is perfectly flat on one side and all thickness variations are on the other side. This saves a lot of planing and scraping time. Using a dial, each micrometer clamp head can be set from 6mm(1/4") to 13mm(1/2") from the centre line to handle work from 13mm(1/2") to 25mm(1") thick. The setting is positive and accurate to a few thousandths of an inch. The movable clamp heads will grip work as small as 13mm(1/2") x 35mm(1.3/8"). With boards of constant thickness, you can set the jig for centered dowelling. For boards of uneven thickness, you set the heads for a constant set back from the reference face.
By using the tapered pin to register off the last hole drilled, you can quickly chain drill dowel holes for tabletops or panels. The movable bush carrier comes with 3 hardened steel bushings: 1/4", 8mm( 5/16"), and 3/8". Other sizes are available. All turnings are solid brass. Machined parts are anodised aluminum.

Very useful for limited applicationsThis jig effectively comes from the Veritas 32 Cabinetmaking System with which, I assume, it works very well. A problem with the jig on its own is that it is quite difficult to locate/register the position of the first hole. When used with the Veritas 32 it has its own dedicated depth gauge (also an accessory to the Dowelling Jig - but not supplied with it) which no doubt assists with the first hole registration on the type of cabinets that the Veritas 32 is designed to help with. However, such a depth gauge is of limited use in other situations. I have found that the trouble is that the frame clamp fittings extend beyond the frame in many narrow end board situations and make measurement to the frame end extremely awkward. The jig has no other immediately obvious reliable way to locate/register the first hole and no help is provided by the instructions. You can get round the problem, but with the design chosen by Veritas, I repeat it is awkward.
