Tired of cutting those pesky cardboard forms to fit some curve so you can
trim a piece of prepreg to fit the first try?  Boy, so am I.  I found just
the hot ticket at Staples the other day.  It is made by Steadtler-Mars and
can be found with the drafting tools in the Steadtler section of the store.
It is a 25 inch long rubber
coated square flexible steel tool for copying any curve.  It comes loosly
coiled in a blister pack and it is electric blue.  It's pretty hard to miss.
For me, it works much better than the duplicator made of many small diameter
rods and it is much longer.  I'm thrilled... hope you will be too.

Wish I had a piece of that action...


[I used a similar device that was made with a spring and a piece of
flexible flat stock, but it was pretty tiny and could only copy gentle
curves that were less than 12" long.  Having worked as a cabinetmaker for
many years I had many opportunities to scribe the shape of a wall to a
countertop or backsplash in preparation for that final installation.   A
foolproof and inexpensive method that has served me well over the years
invloves the use of a simple compass (not the NSEW kind, but the kind that
has two legs that are hinged at one end with a receptacle for a pencil
in one leg and a scribe point at the end of the other.)  Place the
material to be scribed tight against the shape being scribed to and set
the compass legs as far apart as the widest gap between the surface being
copied and the part it's being copied to.  Keep the tips of the compass
parallel to the direction the part will be moved in after the shaping cut
has been made and just follow the contour with the scribe end of the
compass transferring the shape to the part with the pencil.  Works every
time.
