|Thread: PIDDINGTON TOOLHOLDER|
Many thanks Ady1 the photographs of the Model Engineer pages is exactly what I have been looking for.
Has anyone got the articles from Model Engineer by David Piddington describing making his extended toolholder for the Myford Dickson toolpost?
Back in Issue No. 147, Mike Crossfield wrote an article describing a low cost rev-counter. This used a disk with 60 slots to generate 60 pulses per revolution of the spindle.
Is there an electronic device, or a circuit using such a device, that would amplify/multiply the pulses generated by one similar opto switch once per revolution by 60 times. i.e one pulse per revolution increased to 60.
Back in issue No. 147 of MEW Mike Crossfield wrote an article describing a low cost rev-counter. He used a discs with 60 slots (or the 60 tooth Myford Super 7 bull wheel) to generate 60 pulses per revolution which directly read off as a frequency. Is there a device or a circuit incorporating such a device to allow one pick up ber revolution to be amplified exactly 60 times?
