Sometimes we need to use a dial bore gauge that is set-up directly off of a micrometer. It can be hard to center both ends of the bore gauge with micrometer's anvils. Simply cut a small piece of 1/4" rubber tubing and slip it on one side. The bore gauge end will slide...
When working with different manufacturers of blocks, lifting bolt sizes can vary significantly. Our solution was to elongate the bolt holes of our lifting chain on the links towards the end, so that larger diameter bolts can slip through. We then have the thread size...
VOLTMETER SPEEDOMETER For those like me who possess a head and block surfacer that employs a potentiometer to adjust the speed of the traverse, I install a D.C voltmeter on the voltage input of the D.C drive motor. Now I adjust the finish by the voltage of the motor...
MIC CHECK, CHECK One often overlooked item for regular calibration is the common block deck mic and depth mics. Simply lay it on the corresponding precision blocks on your mill table, or known true surface, and check them once in a while. Ron Flood Cedar Machine North...
PAIR OF GLASS PLIERS If you have trouble with flat-band spring-type hose clamps, try using a pair of glass pliers. The jaws are so wide that they hold any hose clamp very securely. They make it easy to compress the clamp for removal, installation, or repositioning....
DIAMONDS AREN'T ALWAYS FOREVER When using my profilometer for bore and surface readings, I hold the drive on the workpiece until the stylus has retracted and recorded it's reading. Then, I lift it off and let it retract without touching the workpiece. This effectively...
