When machining on the CNC mill, it’s necessary to blow the flood coolant and chips off the parts for inspection. I tried a tool holder mounted fan, but it wouldn’t get all the chips and coolant out of the deeper areas.
When the timing cover or block has no dowel pins, or the dowel holes do not fit snug on the pins. Take an old damper and hone the center so that it is now a slip fit onto the crank snout. Use it to hold the cover in place while tightening the bolts.
I needed a narrow grooving tool to quickly clean carbon from piston ring grooves for an engine restoration project. All the usual grooving tools were too wide.
Whether you own a shop or work in a shop, take care of your investment in measuring tools.
