Thank you very much. That is just what I needed.
In the past whenever I ran into this problem I would "triangulate the hole center". I would put the
edge of the covering material where the hole was and run a line upwards. Then I would measure the
distance from the bottom of the underlying piece to the hole center. It gave accurate enough hole
centers but this method is lousy if the materials are cumbersome and when multiholes are needed.
So I was thinking of someway of inventing what I call a reverse screw where I have the holes and screw
into them some special screw that has a very pointed tip or a marking point and then lay the covering
material and these special screws then mark the center of the new holes to be drilled into the new
covering material.
Trouble here also is that some materials are awkward for such a method.
So I am really looking for a method that is almost universal in application and is easy and not time
consuming. Jim may have spotted the universal method in the idea of making a template and once the
template is at hand to imitate the old-surface as much as needed and then put that template onto the
new-surface to get the exact hole centers.
Jim's method is superior to mine because it is more universal.
Hole triangulation is okay for non-precise needed jobs. But where precision is needed and where
multi-holes and awkward materials and irregular shapes of covering make it difficult then the universal
means is to make a template.
I was thinking of an invention of something I call a "behind the wall pencil" where you screw in this
special screw that leaves a mark or hole into the new covering. But I see that such is not as universal
as Jim's idea of a template.
So thanks, it is a template that will solve this problem.
