In woodworking we often need a spacer Not quite! Perhaps we cut a spacer from this wood? Stop! We should save this wood! Let's design an adjustable spacer This design is made from MDF, 1 bolt, 1 nut, 1 tee nut and 1 washer We will make spacers at three different sizes The build starts by cutting all MDF The base MDF is 18mm [3/4"] and the top is 12mm [1/2"] I'm using 90s quick setting epoxy to glue the bases Please Subscribe at the end of the video, thank you! Here I'm preparing the 12mm [1/2"] MDF to make a circular adjustable top I use a forstner bit to drill a recess for the head of the bolt Routing the circular adjustable top I have another video that shows how this router jig works Next we need to drill a hole in the top for the bolt And another hole in the base for the tee nut and bolt Making good progress! All MDF is cut to size, glued and drilled Now we need to insert the tee nuts To start with I use a socket and spanner Then come back with a hammer to make sure they are flush Time to assemble the tops Then it's the final assembly…
Looking good! For the final part of the video, we will test the spacers in a number of different applications We can lock the spacer at a specific height if an additional nut is added Locked! First test: Screw a stretcher into a fake table leg Perfectly aligned The spacers worked well! Second test: Assembling a drawer made with pocket holes Great results! The spacers worked very well here Third test: Prevent vise racking With no spacer, you can see the racking indicated by the red lines Lets set the spacer to the width of the wood we need to clamp The spacer completely eliminated the racking as indicated by the parallel green lines. Perfect! Please Subscribe to my channel for more videos like this. Thank you!.
