The two fixed pins locate all square-ended blades and irons up to a width of 2-5/8 in. (67 mm) or skew blades up to approx. 2 in. (51 mm), depending on the angle of the skew. The sprung 'dissappearing pin' copes with Lie-Nielsen skew blades.
The location pins give you exact repeatablity. The rollers are 'Ertalite'® - a very expensive low friction material. Note: the spring is carbon steel, keep it away from water.
Any other skew is easily accomodated by making up a simple slip of hardwood to fit either next to the fixed or sliding pin - as skew angle dictates. Put a hang-up hole on it and write on what it is for. Thus you achieve excellent repeatability.
This guide is made to interchangeable limits and pin positions are held to + - two thou. in. max. deviation from normal position. Everything is made by R. Kell and checked at every stage.
The required wedge tapers 1/4 in. to 1/2 in., over 2 in. + heel, say width 1-1/4 in. Remember to orientate the grain the right way, use hardwood and ensure the wedge fits snugly at right angles to axle bar. Wedge and blade is NOT included!
The combination of sprung pin for skew, combined with wedge clamping make this guide unique; both are excellent solutions.
Blade projection determines bevel angle. Measurement for this is much less critical than on the 0-1 in. R. Kell guide.
This is a high end quality tool making all plane irons easily handled.
