Circle marking and cutting guide template

A template device and method for guiding a marking implement in marking circular lines upon a workpiece and, interchangeably, for guiding a cutting bit, as in a hand held electric powered router in following the circular lines in a cutting engagement with the workpiece surface comprising;

• a) providing a guide plate comprising a planar member having paralleled opposed major faces;
• b) a plurality of guide holes of equal diameter extending thru said major faces;
• c) said guide holes comprising a plurality of at least three evenly spaced holes in alignment;
• d) said guide holes further comprising a plurality of unevenly spaced holes;
• e) the spacing of said unevenly spaced holes being different from the spacing between said evenly spaced holes;
• f) said unevenly spaced holes located at the end of said alignment of evenly spaced holes;
• g) a first bearing containing pivoting means for said guide plate;
• h) said first bearing comprising a bearing flange, bearing shaft and shaft center hole, said shaft being insertable, rotatable and removable within each of said guide holes;
• i) a second bearing containing means for marking;
• j) said second bearing comprising a flange, bearing shaft and shaft center hole, said shaft insertable, rotatable and removable within each of said guide holes;
• k) said second bearing interchanging within said guide hole with a like diametered means encircling and centering a cutting bit.

A template device for, interchangeably,. guiding a marking implement or guiding a cutting tool in constructing circular lines upon a workpiece surface comprising;

• a) a guide plate comprising a planar member having paralleled opposed major faces;
• b) a plurality of guide holes of equal diameter extending extending thru said major faces;
• c) said guide holes comprising a plurality of at least three evenly spaced guide holes in alignment;
• d) said guide holes comprising a plurality of unevenly spaced guide holes;
• e) the spacing of said unevenly spaced holes different from the spacing between the evenly spaced holes;
• f) said unevenly spaced holes located at the end of said alignment of evenly spaced holes;
• g) a first bearing means insertable, rotatable and removable within said guide holes providing pivot means for said guide plate;
• h) a second bearing means insertable, rotatable and removable within said guide holes containing marking means;
• i) said second bearing interchangeable with a like diametered guiding means encircling and centering a cutting tool within said guide holes in said guide plate.
