Queensland Railways (QR) 2'8" Buffer Height Gauge For: 1.64 Scale, S Scale on HO / 16.5mm Track Use: This simple gauge makes checking rolling stock buffer center heights easy and convenient on the workbench. Buffer Scale 2'8" Height Gauge: - The Buffer Scale 2'8" Height Gauge should be 12.7mm (+ or - 0.05mm), from the top of the rail to the top of the gauge (see the photo vernier calipers). - Make sure it sits between the 16.5mm gauge track rails (as per photo), showing the height of the center of the buffers. - The Buffer Center check is not for checking buffer length or buffer distance apart; these measurements vary depending on the prototype. How to Use: The tongue is narrower than the buffers, allowing you to get up close to the body of the wagon and determine if packing needs to be added or removed from bogie mounts. Note: The Buffer Center checker is not designed for checking buffer length or buffer distance apart; note that these measurements vary depending on the prototype.
