Marples Trial 1 Rosewood Try Square

Handmade in Sheffield by Joseph Marples, these beautifully made brass bound rosewood try squares are part of Marples’ Trial 1 range of 70 year old designs. It has a hot blued steel blade secured with three diamond brass washers and steel rivets.Each square is tested for accuracy on both the inside and outside faces during manufacture and again before despatch to us. Marples own specification for the internal angle is twice that specified in the British Standard i.e.; better than 0.01mm/10mm blade length and with the solid brass edges – accuracy is ensured.Carpenter’s try squares are designed for squaring across sawn boards in preparation for sawing to length. Because the outcome can only be as good as the sawn surface that the stock is registered against, there is a limit to how much accuracy is relevant and this is reflected in the standard.Conforms with British Standard 3322 specification for carpenters’ squares and bevels.size (in)Inside blade length (in)Overall length (in)Stock length (in)445½4666½4½99116¼1212148
