I remember reading that article several years ago. Yeah, interesting perspective. Here's my story: this spring I overhauled a LeRoi Dresser 2 stage air compressor I've had for about 30 yrs. The thing is about 60 yrs. old and had a rod bearing knocking. The overhaul kit had two new pistons, rings, etc. and all needed for an overhaul. There were never any oversize pistons made for these and if the cyl. was worn past limits, you had to replace it. The high press. cyl. (2 in. bore) was about 1 thou. past limits. The only new cyl. I could find on the internet was insanely expensive. I'm lucky to have a very good machine shop close to me and they bored and sleeved that worn cyl. to original bore size. The low press. cyl.(4 in. bore) was still well within limits on bore. I had no cyl. hone big enough for this 4 inch. low press cyl., so just put in the new piston and rings and no honing. High press. cyl. got the same and the sleeved original size bore. Put it all back together and this thing was taking way too long to get to cutoff press. 180 psi. Much longer than before I tore it down. There's a chart in the back of the maint. manual on the compressor that shows the different models and how long they should take to get to different cutoff pressures. Mine was out of whack according to the chart. I ordered a new ball hone big enough for the unhoned low press. cyl., took it back off, honed it and put the compressor back together. I'd already rebuilt all the suction and discharge valves. Nothing else was touched except to hone the low press. cylinder. Ran it up to cutoff press. and the first time I ran it, the compressor made it to cutoff press. much faster. And got there in a shorter time the more I ran it. There's only one thing that was changed. Honing of a cylinder. No, it's not a gas or diesel engine, but it's cast iron cylinder and aluminum pistons. I'm calling BS on that article.
