Find out the shrinkage of your claybody (ask your supplier). Cut a
template of the the switch plate you wish to make. Find a copy machine.
If your shrinkage is 10%, make a copy of the template, but set the
copier for a 10% enlargement. Use this as your template.
Hope this helps,

Deb Erzen,
First I calculate the exact shrinkage of the clay I am using by test firing.
Then I take a standard light switch (or plug, etc.,) plate and scan the image.
My scanning software allows me to increase the size of the final image by any
percentage. I increase the size to accommodate the shrinkage. I the print
the enlarged image and use that as a template for the holes I need to cut,
etc. As long as I cut very carefully the plates fit perfectly.
If you have any further questions fell free to ask. Good luck.

A friend of mine told me of the following technique she learned in a
workshop. Make a ruler bar of your clay with careful measurements, fire
it to temperature and calculate the exact shrinkage of your clay. Draw a
full size template of a light switch and take it to a copier which
enlarges. Enlarge the pattern by whatever % your measured shrinkage rate
is and use the enlarged copy as a template.

Deb- zerox an existing plate- you say shrinkage isn't a problem- but if it
were, many zeroxes allow you to enlarge by your chosen percentage.

Go out to your local hardware store and buy a plastic switchplate and
start from there.

Hi:
I've never done this but maybe this will work. A friend makes switchplates
and she took a switchplate to a shop that has a good copy machine and had
copies done of the plate that were sized bigger, according to the shrinkage
rate of her claybody. I guess that copy machines can be set to enlarge
things on a percentage basis. Anyway, she said it worked perfectly.

Wonderful help! Why wouldn't this also work for replacing a lid for a piece
that has already been glaze fired? In fact, I think I'm going to work up a
'paper' that has several different size circles, so I don't have to continually
guess how large to make the neck of a small bottle so that my pump dispensers
will fit right....or for my 3" cork lids.....this could have several
possibilities...... Thanks

If you are trying to account for shrinkage by Xeroxing, in order to get
the right enlargement size, (even if you are just calculating the size)
you cannot increase by the shrinkage rate since this is working from the
finshed size. If your clay srinks by 10% then divide the finished size
by !00%-10% (1.00-.10=.90). This will give the proper size to make.For
example:
Finshed 12" platter with clay that shrinks 10%. The proper thrown size
is !2" divided by >9 = 13 1/3". That is the size that will shrink 10%
13.3 - 1.33 = 12.0".. If you enlarged The original by 10% the thrown
size would be 13.2" In a platter the difference might not matter but in
a plate switch, where the center to center distance of the screw holes
are very exact the slight difference will present a problem.
