Making your own leveler can be a great way to get the job done quickly and easily. First, you'll need to find a flat surface such as a piece of plywood or metal that is large enough for the workpiece. Place the workpiece on top of this surface and then place two small wood blocks at each end of it. The blocks should be placed so they are slightly higher than where you will be measuring from – usually about 1/8 inch above the workpiece's surface. Then use either an adjustable wrench or an Allen key to adjust one side block until it is perfectly level with the other side block, making sure to double-check by using a spirit level across both blocks. If everything looks good, then screw in some screws at each end into both ends of your workpiece to ensure it stays put while you measure from it using your chosen tool (such as a ruler). And that’s all there is to creating your very own homemade leveler!
