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

Product Information

Though we never cut through a section as I did, it is comforting to see just how the wedges work to both compress the wood fibres and also close off any and all relevant air pockets and that there is zero splitting. In the video, you turn one of the wedges, saying something like: that one is in the wrong way (at about 1′).

Please include what you were doing when this page came up and the Cloudflare Ray ID found at the bottom of this page. One wedge secured the plug to the frame and another at the outer end of the plug secured the board to the plug. As mentioned, the fox-wedged mortise and tenon is rarely used but it is used as a rarer solution where pulling power is needed over long-term use. 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.In the old days a young guy starting of in the building trade, very soon came across the use of wedges. When the joint and wedges were in place, he took a heavy sledge and pounded the stile until it seated to the shoulders. I have quite a number of steel, brass and bronze wedges for jobs in non spark areas and refineries etc.

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. For us novices, drilling the end hole before cutting the slot may also help prevent cutting past the intended depth.Rather than the danger of pounding your joint and the tenon shoulders not closing, which would be a glue up night mare. It’s good to see additional areas like the ends of the wedges indenting into the bottom of the mortise and the retention properties afforded adjacent to the extended area on either side of the mortise opening. 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. 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. seen em used quite a lot in pairs,,, used them meself when we were putting the back veranda up to square it up.

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. Wedges are commonly used in building and DIY work, to hold on axe heads, the axe head itself, to wedge open doors, the ends of chisels and other cutting tools are wedges, the ends of nails etc. This maximises wood where it is needed and the shouldered sides seat the joint and work as long-term lateral stabilizers. If you try knocking the wheel with a hammer without knocking a fox wedge in each of the collars the collars bind on the stainless shaft and make a right mess of it (if you can get the wheel to move at all).That said, I have noticed a tendency for single, centred wedges to show traces of a split into the visible wood outside the tenon. Longer tenons flare out more readily than shorter ones which will offer greater resistance to spreading.
