Aluminum caliper - thickness gauge for measuring diameters and wall thickness of turned workpieces. 

Thickness gauge is a practicall, basic toll in every woodturning workshop - it measures thickness of walls and turned workpieces. Very simple, light aluminum construction allow the caliper to be used with one hand. Specially designed, round jaws allow for measuring the workpiece while simultaneously keeping the lathe going. Ergonomic shape will enable you to put the caliper inside turned workpiece. Measurment range between 1mm and 55mm with resolution of 1mm. 

Holes drilled every 5mm allow to block the gauge on choosen diameter, so that turned workpiece can be processed to this diameter.  

Parameters:

- maximum measuring range: 55mm, resolution every 1 mm (though the caliphers may be spreaded more if You need to)

- maximum depth of measurment: 55mm

- total lenght of caliper: 243mm

- caliper may be blocked with a pin every 5mm

- material: aluminum
