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 a choice
of Rosewood or Walnut which are finished with brass parts that contrast
and complement the rich wood.
The wooden 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.

Trial 1 Rosewood Marples Square
J Marples Carpenter's Square
From my observations,
I believe in around 2019 Joseph Marples began offering Walnut alternatives to their
Rosewood tools due I would imagine in part to the approaching new CITES updates on the import/export
of Rosewood. From what I saw, the Rosewood version remained the popular option amongst
retailers and woodworkers at this time in the UK.
From my observations, the choice of Walnut began becoming a mainstream
option in around 2020-2021 when I believe there were Rosewood supply
problems to the UK (possibly globally), I believe due to Covid related disruption,
this I would imagine opened the door for some retailers to start stocking the Walnut
version.

"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."
