The Rockler Router Bit Center Depth Gauge (55010) is priced at $19.99 and can be purchased exclusively online at or at Rockler Woodworking and Hardware stores nationwide, as well as through the Rockler catalog. The head of the gauge also includes a flat "depth" section for measuring from the edge or the top of a cutter, allowing the gauge to be used to set bit or blade cutting height. Holding the gauge against the bit shank, the user adjusts the router table fence until it's tight against the broad foot at the bottom of the ruler and locks down the fence. Then the user moves the gauge up to the bit, fitting the correct half-round slot – 1/4" or 1/2" – tight to the bit's shank. To set up a router table for cutting grooves or dadoes, the user slides the clear beveled indicator to the desired metric or imperial mark on the 12" rigid steel ruler and locks in the setting by tightening the knurled knob. The Rockler Router Bit Center Depth Gauge allows users to quickly set their router table fence a precise distance from the center of the bit, says the company. "The Rockler Router Bit Center Depth Gauge allows you to do both quickly and accurately." "Setting the distance from the fence and the cutting height of the bit are two of the most important operations when routing grooves or flutes," said Steve Krohmer, Rockler's vice president for product development.
The gauge also can be used to precisely set the cutting height of router bits and saw blades. The Rockler Router Bit Center Depth Gauge () enables users to quickly set the fence on a table-mounted router – or an edge guide on a handheld router – an exact distance from the center of the bit, which is essential when routing dadoes, grooves or flutes. 10, 2019 /PRNewswire-PRWeb/ - Rockler Woodworking and Hardware has developed a tool to help make it quicker and easier to achieve pinpoint accuracy in common router setup operations. Your state government probably maintains a database of drillers' logs that have water levels recorded when a well was drilled, and hydrologic consultants often have reports that contain water level data from shallow boreholes.Ĭonsulting any or all of these sources is a good first step in finding out the depth to the water table.MEDINA, Minn., Oct.Use their Data Portal to zoom in to your area of interest and click on any site. The National Groundwater Monitoring Network is a compilation of groundwater monitoring wells from federal, state, and local groundwater networks across the nation.Click on any red groundwater pin to access the data (need to zoom in to change the dots to pins). A convenient way to find data for your area is by using the NWIS Mapper and selecting "Groundwater Sites" in the menu on the left. The USGS National Water Information System (NWIS) has depth-to-water measurements made in the present and the past.The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.ĭatabases containing depth-to-water measurements can also be helpful, though they don't always have current data: When water-loving plants start to grow again in the spring and precipitation gives way to hot, dry summers, the water table falls because of evapotranspiration. During the late winter and spring when accumulated snow starts to melt and spring rainfall is plentiful, water on the surface infiltrates into the ground and the water table rises. The depth to the water table can change (rise or fall) depending on the time of year.
