Acetate ?

[todd8137]

Hi every one I would like to no we're I could get a piece of acetate with a printed 16" circle on it with a X in the centre of the circle ,

Why ? To center spot my mirror as I can not find a compass and the ole string and drawing pit is not good enough ,so does any no where I could but this from I dare not take the mirror out the cell and this is the only way I can think of doing a safe way unless some one can make me some paper circles or no we're I can buy them ?

Thanks in advance

Cut a piece of paper to a 16" circle, fold it 3 or 4 times where the creases meet is the middle cut out the middle and thats you template....

Hi tinker I have no compas that will draw a circle this big ? I have tried the pencil string and tack it's a pain trying to draw a perfect circle and holding the pencil at the correct angle all the way round

Thanks

It doesn't have to be a circle - cut a 16" square of paper and fold on each diagonal to find the centre.  Open out and fold into quarters (ie two more folds that will also meet in the middle).  Open out and cut off the corners (quite a rough circle will do) and you have a useable template.  The folds will allow you to align it adequately.

To get the right size circle just lay the mirror on the piece of paper and draw round it ... 

Then fold in half and mark the centre of the diameter .

I keep thinking that the spot as to be mm perfect on the primary ?,what if it was of by say 5mm ? How much would it mater ?

If you fold the circle in half and then into quarters the intersection of the creases will be exactly central , then just clip the corner off with scissors to give you the access for spotting.

use a large dinner plate or pizza flatplate or anything of the right sort of diameter. get it as central as you can. check the dot by measuring four ways before sticking your centre circle down.

taking the mirror out makes it a lot easier though.

You must have a healthy appetite to need 16" dinner plates sir ...

I do unfortunately hence my supposed diet!

Better to have Starter , Main and Pud all on one big plate , saves on washing-up ...

I will get there in the end
