Router template for use when creating holes for Blum type hidden cabinet hinges. These hinges are commonly available from many sources, e.g. at Ikea (Utrusta, Complement and Integral).
The design assumes a router template guide diameter of 18.3mm and a 9.5mm bit, but this can be easily adapted. Also the distance between the mounting screws seems to vary depending on the model. 45mm seems to be the most common size, but I think 48mm and 42mm are also, or have been, used. When fitting, if you have trouble with the screw holes interfering with the main hole, try using a larger diameter router bit.
There are various templates on the market that do the same job, but they all require a 35mm bit for drilling. Some of the templates will also make a deeper central hole, which can be a real problem for thin walls. With this tool you only need your standard router with template guide installed and a standard cylindrical bit.
