Years ago an old school machinist told me "It's an end mill, use the end!" To that end there was an article in The Home Shop Machinist in one of the earliest issues on building a simple attachment for sharpening the ends of end mills. Try looking through their on line index for it. as I recall...

First recall that antifriction bearings are used on both ends of the rod because the combustion loads and the inertial loads combine to give a continuous compressive load which prevents developing a lubrication wedge in the bearing gap. Some engines can be designed with weighted pistons allowing...

Backing up 100 years aircraft engine design was focused on weight and cooling. A serious approach was the rotary engine that had radial cylinders on a crankcase that spun around fixed crankshaft. Pistons and cylinders were machined from alloy steel for maximum weight reduction. In higher...

I had a hard bolt break off in a mild steel bushing welded into the chassis of a car. I knew from bitter experience that any drilling effort would lead to a hole in the bushing.

Cumins was the name of the traveling tool show and I bought a rather good 7X12 Minilathe from them. The Cummins Diesel people made them change the name and they vanished soon after. Bill in Boulder

Fpr a 30 mile move consider getting a price from a tow truck. A friend had a Bridgeport mill moved across town (~30 miles) for $50. The tow truck just put slings around the mill, lifted it up, and rigged antisway cables to steady it. Set it down at the shop door! Bill in Boulder CO USA
