Follow-up Success on Honing Heavy Scratches - Arborist, …
网页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...
is this a ball hone - Arborist, Chainsaw & Tree Work Forum
网页Apr 20, 2007. #5. That is the correct ball hone and will work with your 47mm cylinder fine. They are already slightly oversized. Dip/soak the ball hone in a very light oil to coat all the balls completely before use. I give mine a short "break in" in an old cylinder or or water pipe - they are very aggressive when new.

网页2004年5月2日 — 2: Removal of burr. As metal is ground to thin cross-section (i.e., sharpness) it does not form a neat triangular profile: the tissue-thin edge and attached debris curl over into what is called the "burr" or "wire." We must abrade or fatigue this microscopic "steel wool," to expose the underlying solid edge, via the honing process.
Honing the Cylinder On a Stihl - Arborist, Chainsaw & Tree Work …
网页Jan 28, 2009. #2. A break cylinder hone will not go through nearly as soon as a ball hone. The ball hone is larger than the bore and hits the edges of the ports. That's where it cuts through. It would take a lot of honint to cut through with a brake hone. That the reason I like them. You just have to be careful pulling it out and hitting the ...
Best way to prep cylinder for new piston rings
网页2016年12月7日 — The longbar PNW. Jan 14, 2017. #2. If it is stamped Mahle or Stihl its Nikasil plated. Look on the sides for the name in the casting. Actually any OEM 026 cylinder should be Nikasil plated. As for new rings, I would deglaze the jug lightly with emery paper using a drill. I use a 1/4 inch paddle bit with a 1/2 inch by 4 inch strip of emery cloth ...
Re-Sleeving Stihl Nikasil Cylinders - arboristsite.com
网页Mar 24, 2007. #1. I was wondering if anyone had any luck re-sleeving the Nikasil cylinders with cast iron or stainless steel. Wiseco use to sell sleeves and pistons for my CR 500 back in my District 6 racing days. I have a 088 magnum that has a scored cylinder beyond saving, but I cant see paying 450.00 for a new piston cylinder set while I ...
Sawdust size while milling - Arborist, Chainsaw & Tree Work Forum
网页2017年5月4日 — IIRC about 20% of file (round not square) is a good amount to have above crome. Sharpens while leaving enough steel below the chrome as a support for tearing chips off, if the depth guages are low enough to allow a bite the power head's torque can make with out bogging down. A sharp ( small angle) edge is not supported & breaks away quickly.
McCulloch Super Pro 125C motor - Arborist, Chainsaw & Tree …
网页2013年6月17日 — Location. United States. Aug 6, 2013. #1. I bought a SP125C a while back with the intention to rebuild it and use for some large tree work and Slabbing. I have always wanted one and found one on ebay that was complete but had no spark. The saw looked in great shape and I wanted it bad enough, that I won the bidding at $320.
Honing a Shihl Cylinder. What's the proper grit?
网页Dec 22, 2011. #7. you cannot achieve a 45* crosshatch on a nic cylinder with nothing less than a diamond hone. a 280 alum-oxide stone is about the only grit available for these tiny bores. it will only rough it up. the color will change. chrome is softer and thicker by a few thou, but be careful.

网页2017年10月19日 — St. Petersburg, Russia. Dec 16, 2017. #1. Good evening, gentlemen! 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 ...
