About this deal

In the old days a young guy starting of in the building trade, very soon came across the use of wedges. 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. There are advocates for using small holes at the end of the saw kerf to work as stops to stop the wood from splitting. Dovetailed mortise, wedges ready for applying pressure via clamp or hammer blows in successive blows. A wedge for expanding the split end of a bolt, cotter, dowel, tenon, or other piece, to fasten the end in a hole or mortise and prevent withdrawal.

It maybe a regional thing, Wedges/fox wedges are a just a very useful tool that have multiple uses, always have a few handy .In a video I once saw the same technique used in wooden boatbuilding when fastening the outer boards of the hull to the frames with wooden (round) plugs. To the left side shows no extended wall which creates a fulcrum point that can cause a fracture across the grain at the sharp bend. First, chop the mortise to the exact width of the tenon with no allowances to the wide width of the tenon. In the video, you turn one of the wedges, saying something like: that one is in the wrong way (at about 1′). It may not be needed in this case where the mortise walls will be pressing inward on the tenon, combined with wood’s flexibility … but if you’re concerned, it’s a legitimate approach and it’s cheap insurance.

Longer tenons flare out more readily than shorter ones which will offer greater resistance to spreading. Drilling a hole to strengthen a slot or right-angle is a classic trick, distributing the forces that would otherwise tend to be concentrated at the intersection of the two planes. We also use them for lifting machines or creating gaps, you would be surprised on just what you can lift by knocking a steel wedge underneath a machine weighing a couple of tonnes. Of course, it is not always necessary to dry down further than the relative humidity in the surrounding atmosphere in which the final piece made will live. 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.They condemned two pairs of forklift truck forks a few weeks back when I was on site, they were destined for the scrap skip after a firm came in and NDT tested them and found cracks. My dad had popped his head into the garage every hour or so, taken the **** and gone back in the house. Because of this, you are unlikely to ever see or even know such a joint type has ever been used let alone existed.
