Edward Preston Square Review By: I.Ball

Category: Old Squares

Manufacturer: Edward Preston

Tool Type: Diagram / Architects / Tailors Square

Model No:


This Edward Preston diagram square, also referred to as an architects square is a folding square which opens to a 90 degree angle to form a small version of a tailors square.

The square can be used for all three uses / professions which no doubt is not the exhaustive list of what this square has been used for.

This well-made Edward Preston square is made from boxwood which is combined with a special 90 degree brass hinge and brass ends.

The outer edges on the top side of the folding rule square are bevelled to give a nice steady slope from the edges to the face; a feature which is common with old architect's rules.

The upper sides are marked 1-24 on each arm which are further broken down into 4 increments for each number. Each of the 1-24 measurements measures 1/4 inch.

The rule is marked 'E. Preston & Sons, Birm Eng'.

"Just stumbled across your website and an absolute treasure trove of information. I was recently given an old Stanley 110 block plane and wanted to know more about it. Your website told me everything I needed to know.

But there is so much more to read. I forsee me spending a lot of time just reading page after page. I can appreciate how much time this will have taken to put together.

I just wanted to let you know that your hard work is appreciated."
