J.Marples Trial 1 Square Review By: I.Ball

Category: Squares

Manufacturer: Joseph Marples

Tool Type: Try Square

Tool Range: Trial 1

Model No's: T06, T09, T12

The Joseph Marples 'Trial 1' squares are the top of the range squares from the Marples squares range.

These Sheffield made, Joseph Marples try squares are made to traditional designs with tempered blades blended with stocks made from Rosewood which are finished with brass parts that contrast and complement the rich Rosewood.

The Rosewood stock is fitted with a thick brass plate on both the inside and outside edge of the stock; a feature which most try squares of this type don't have.

The brass plates are 3mm (1/8 inch) thick and are machined for accuracy.

The additional brass plate gives the stock extra weight over the other Joseph Marples square designs and most similar try squares.

The brass plates also have the function of helping to protect the square from damage, maintaining accuracy, and giving the tool a great look of quality.

The Joseph Marples Trial 1 squares are made to the British Standard BS3322 with each square checked twice during the making of the tool for accuracy and once again just before leaving the factory.

The testing includes checking the inside and outside faces with the testing for the internal angle checking for accuracy which is twice as accurate as the British Standard.

Each Joseph Marples square comes with a 'certificate of calibration'.

The Joseph Marples Trial 1 try squares are available in three sizes:

- 6 inch
- 9 inch
- 12 inch

The Joseph Marples 'Trial 1' squares form part of a range of 'Trial 1' tools which can be purchased individually or as a box-set.

The Joseph Marples 'Trial 1' range is based on an old Joseph Marples square design from about the 1940’s which also went by the 'Trial 1' mark.

Joseph Marples Ltd advertise the Rosewood used as coming from managed, sustainable sources.

The Joseph Marples tools are made in the 'York Works' factory in Sheffield, England. The current 'York Works' factory was purpose built in 2001.

Note: there was also an early Joseph Marples factory called the 'York Works'.

The Marples name has a long history in tool making. Different factions of the Marples name have been synonomous with good hand tools for many, many, many years.

Joseph Marples Ltd continues the family line of Joseph Marples which has a lineage back to the 1840’s.

The tools made today combine modern technology and traditional manufacturing methods to produce traditional tools.
