Mount a straight plunge-cutting bit in your router and set the router bit to cut about 3/8 in. deep for the first pass. A plunge router works best, but if you donât have one, hold the router above the wood and start it. Carefully plunge it into the wood and begin moving it counterclockwise around the circle (Photo 2).
Decision Matrix Analysis works by getting you to list your options as rows on a table, and the factors you need consider as columns. You then score each option/factor combination, weight this score by the relative importance of the factor, and add these scores up to give an overall score for each option.
With a good understanding of space needs, the relative merits of the factors to be considered should be weighed. First, the critical factors must be identified; then the others, even though not determinant, should be reviewed. An explanation of the factors to consider follows. In addition, a matrix of decision factors has been provided to define the possible optimal solutions based on these factors. Note that not all projects fit neatly into this matrix; it is simply meant as a guide and special circumstances will require exceptions.
