6/29/2002 The secret to grinding high speed steel is to remember that HSS is abrasion and heat resistant. These two properties make it resistant to grinding. A grinding wheel is a cutting tool and the abrasive grains are in effect its cutting teeth. If the abrasive grains are dull from use they wear more then they cut causing friction thus heating the tool.

11/21/2018 A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.

7/8/2013 For hand held roughing of HSS I use a wheel with 46 grit in the I hardness. On a 6-inch grinder at 3450 RPM use the 7 x 1/2 inch wheels. These are 1 bore wheels so you will need to make a spacer and you could have some guard issues but I assure you that if you can manage it, it is worth the effort.

gravel to control water accumulation | home guides | sf gate

If puddles are the problem, gravel could be the answer. Unwanted water accumulation makes paths messy and slippery, turns beds and borders into waterlogged swamps and drowns container plants. Fortunately, wise employment of gravel can make all of those problems go away. Grand River Natural Stone notes that the best size gravel for drainage ranges from 1/2 inch to 1.5 inches in diameter, depending on the project.

Water drains more quickly through gravel than it does through most types of soil, so using rocks to divert water helps mitigate standing water in landscapes and on walkways. By diverting water or offering traction, especially in areas that see foot traffic, homeowners lessen slip-and-fall hazards. Puddles form less readily on gravel-covered pathways and borders than they do on soil surfaces.

Some landscapers recommend putting down layers of sand and crushed rock beneath gravel in order to stabilize the surface, but a simple 2- or 3-inch layer of gravel will deter puddling and will also avoid the possibility of the sand and rock working its way up through the gravel.

When water accumulation is more severe, the situation calls for a more elaborate drainage system than a simple layer of gravel, but gravel is still an important component in the solution. A French drain is a gravel-filled trench that directs water away from an area where it accumulates and disperses it somewhere more appropriate.

The simplest French drain consists solely of a trench that provides a pathway for water to follow; gravel in the trench prevents debris from collecting and impeding the flow of water. More complex drains utilize a perforated pipe placed at the bottom of the trench to better channel the water, and here too, gravel over the pipe keeps debris out of the drain.The best size gravel for drainage in a French drain without perforated pipe is 1.5 inches.

Because they are elevated above the surface soil, raised beds allow gardeners to plant in areas where water accumulates. However, raised beds -- especially those deeper than 18 inches -- may have drainage problems of their own as water flow is impeded by the sides of the bed. In deep beds, the best aggregate for drainage may be a layer of gravel at the bottom, beneath the soil, which allows water to move more quickly through the soil so that it won't accumulate around plants' root systems. Oregon State University Extension Service also recommends a layer of crushed gravel beneath filtration rain gardens

The University of Illinois Extension advises against putting a layer of gravel beneath the soil in containers, asserting that water tends to accumulate above the gravel layer rather than draining into it. A better recommendation is to use only a good soil mixture in containers and if you use gravel at all, place a layer under the container so that water evaporating from the damp gravel will increase the humidity around the plants.
