2011年12月11日 · Many posters on this great site may recall our spirited discussion about the pros and cons of 2 cycle cylinder honing about a month ago. The story ends with my saw being back together, running perfectly. Compression is up from 90 to 140. Investment= $28 hone and a $5 ring. Opinions varied...

2011年11月24日 · measuring piston to cylinder fit is an art form. pistons vary, as do cylinder bore. making a torque plate jig would take a while. honing process is an art form to get correct x-hatch and finish. even removing a hone takes care. cleaning cyl after honing properly takes a very long time. ring fitting, etc.

2016年12月7日 · In terms of cleaning up the scum layer to expose a fresh wall, at best the layer of scum is comprised of alum., steel, wood, oil , nickel and silcarbide or chrome. All of it needs to be smaller than the porosity and surface texture of the coating to exist and again honing will not remove it beyond the visible lines left by the hone.

2020年8月29日 · Hey guys so I’m trying to learn about cylinder honing as I have a stihl 044 10mm pin saw that I want to “freshen up” as the compression is around 138 psi. I plan to put a new oem piston and rings in It. So I’ve done a little reading on cylinder honing and this is what I’ve gathered so far: I need a flex honing tool.

2011年12月22日 · I've read several articles on cylinder honing, and recommended final grits of 240-400. I don't want to enlarge the bore, but just scuff the cylinder wall to receive a new ring set. What's the best to use?

2017年10月19日 · I'm currently trying to clean up a Nikasil plated cylinder from an 036. It had some aluminum transfer from the piston and some scoring. I tried please clean it up with sandpaper but the plating is very hard and it doesn't really do anything. So I went ahead and took some fine diamond lapping paste and put it on my little honing device that I built.
