Klein Tools Fox Wedge, Stainless Steel, 4-Inch 7FWSS10025

Product Information

For this instructional we will have two bare-faced edges to the tenons, so shoulders to two wider sides. even when the joint is cut tightly between the end walls, that wood does yield, especially in less dense woods like oak and the wide range of soft-grained woods. when double wedging, you are using RIGHT-angle triangle shaped wedges rather than isosceles triangles? This will stop the wood from splitting as the wedges tighten when the tenon aspect of the joint seats fully against the mortise piece.

Because of this, you are unlikely to ever see or even know such a joint type has ever been used let alone existed. The wedges then serve to fill the gaps causing the play, giving a mechanical boost to the strength of the joint and allowing glue to work properly. They are also handy if you need to split flanged pipework as you can remove the bolts and knock a wedge in right on the edge of the flange that will give you a gap large enough to get a new gasket in etc. Bear in mind that the maximum cutting capacity of the Rage 2 is 6mm and that the forks are about three inches by 1.

Inside the mortise, after you’ve chopped out the main mortise, pare down the end walls at an angle to gradually widen to the bottom of the mortise, giving room for the wedges to spread into the vacant space and so give it the dovetailed effect that the joint depends on. Fox wedging seems to be touched on as a theory of hidden mortise and tenoning with a concealed mechanical dynamic. I have quite a number of steel, brass and bronze wedges for jobs in non spark areas and refineries etc. I can see this in many applications of boatbuilding and for several good reasons not the least of which is the permanence of swollen wood once the dried-down peg is inserted and living in wet areas permanently and then the non-erosion of key metal components through exposure to saltwater and water in general.

Somewhat often the author will mention and name of someone influential in the field and then mention a book that chronicles their work that also contains measured drawings. hi paul, this is a GREAT article, and putting in the wedge the ‘wrong’ way initally in the video was a useful learning moment for me.I try to gauge the thickness of the wedges by estimating the play that is present in both mortise and tenon, and the amount of existing material I have to work with. If you need to position or move the wheels on the shaft you loosen the screw in the split collar but then you need to create a gap in the split collar before you can move the wheel (there is a split collar at each side of the wheel with a stainless pin going right through the wheel). Foxtail wedging is the use of a wedge for expanding the split end of a bolt, cotter pin, dowel, or tenon to fasten the end in a hole or mortise to prevent extraction. Another common use for steel wedges is to raise and position steel columns, a wedge will lift it as required and also hold it in position whilst fixing down and packing. I started off making 6 wedges, two for myself and two for two other fitters on the day team, then I made 4 more for two of the shift fitters.
