We had another fantastic and very busy week exhibiting at this year’s Midlands Model Engineering Exhibition at the Warwickshire Exhibition Centre as we got a chance to meet some familiar faces, as well as welcoming some new customers to our stand. Its always good for our customers to engage with our Technical Product Specialists on the stand and to help with lots of different enquiries you may have.

We look forward to our next exhibition, keep a close eye on what’s to come.

Feeler Gauges are used to precisely determine the size of small gaps between two objects that are in close proximity and usually consist of several finger-shaped strips of thin metal which vary in thickness (also known as leaves or blades), secured at one end by a pivot pin.

Metric and imperial versions are available, each individual finger is etched with the thickness of the finger. Multiple thicknesses can be achieved by layering several fingers together to reach the thickness you require. If the gap is larger than the blade, and there is little or no resistance, change to a thicker gauge or add additional blades until the resistance feel is correct.

Feeler gauges are traditionally used by mechanics for the fine setting or verification of clearances between two parts, such as spark plug gaps, ignition ‘points’ on a petrol engine or engine valve clearances or ‘tappets’. Engineers would use feeler gauges to check the clearance between two parts, this may be checking a manufacturing tolerance, or measuring for wear or warping as part of a service or maintenance routine.

There has been a fantastic article written by one of our customers who purchased the Vertical Linear Digital Scale for his milling machine to eliminate backlash.

“On my machine, even with the spindle bearings correctly adjusted, there is around a millimetre (40 thou in imperial) of backlash, I assume this slack must be in the rack and pinion, the effect of this is that the quill clamp always needs to be slightly tightened putting additional pressure on the rack and pinion making it harder to move the quill. Failure to clamp the quill can result in a chattering cutter that can drift up and down when machining. I have seen people fit springs to hold the quill rack up against the pinion but spring rates change as the spring is stretched so the lift force gets stronger as the spring gets longer, again causing more pressure, hence wear, on the rack and pinion. What is required is a DRO device that will give a constant force at any length, in other words, a gas strut!”
