Cylinder Honing Questions

[FernGreen]

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. I need to “crosshatch.” Does the flex hone do the crosshatching or is there a certain way you use the hone that creates the crosshatches? Where should I buy the flex hone from? I saw them on baileys but I did not find one that was 10% oversized (55mm). What grit should I use if I’m just trying to prepare It for the new rings? Also if you have links to any good write ups or videos that’d be greatly appreciated.
Thanks in advance!

I just use a red Scotch Brite pad to clean up the cylinder.

Ok so I figured out that you just order the size for your bore, the 10% oversize is already factored in. I also dug up an old thread of a bunch of guys arguing with each other about whether to hone or not. Has anything changed or is this still a heated debate?

Clean it out good with carburetor cleaner and run some scotch brite with kerosene or mineral spirits on a mandrel. Put new rings on it and run it like you stole it

One wrong move and your cylinder is trash. It’s not needed

I normally chuck a screwdriver in my drill and wrap a red pad folded over around the handle.

Awesome thanks for the idea I’ll give that a shot instead.

Man those look perfect! Those are just a scotch-brite pad on a wheel right? Where did you pick those up at?
