Wondering what the setting is on the 3/8" Husqvarna...escalated

Question:
Wondering what the setting is on the 3/8" Husqvarna depth gauge tool, and if there are different tools available with different settings.
Details:
The reason I ask is that it seems the factory depth gauge setting on Oregon LGX is shallower than the setting on the Husky tool (meaning I can place the tool on a new out-of-the-box loop and file some material off of the depth gauge). This is consistent with my experiences of a chain filed with the tool cutting more aggressively than a new chain. Other depth gauge tools I own (Stihl) set it higher and the cut is smoother). In softwood it is fine, but too aggressive in most hardwood. I am using the hardwood setting.
Answer
Chris,
I have several different gauges and several different chainsaws, all 3/8 and .050 gauge including a stihl, I have noticed that most 3/8 gauges are set for .025 " depth for hardwoods, and .030" depth for softwoods, all of my gauges have both settings (Oregon, Stihl, and Husqvarna). Husqvarna makes two types of gauges also, one is strictly a gauge, and a very rigid gauge and well made, the other one is both a pocket file sharpening device with built in gauge, The gauge portion swivels underneath or folds up to make it more pocket friendly, however due to the swivel which is like a washer with a rivet, I noticed that this specific gauge will give a few thousands thickness less because its not completely flat.
Anyhow, I'm not sure this really answers your question but I have also seen a difference on what type of chain I am sharpening too, some have the safety raker, and others do not, so depth sharpening is a little different too.
I hope this helps.
PS. I have some brand new LGX chain, so maybe tomorrow I can do some experimentation, and check out your observation.

Chris,
Some additional information, today I measured a brand new "72 LGX072G" round ground chisel cutter chain. The raker links or depth gage links measured ( .506 ") from where it rides on the bar rail to the top of the raker link, and a cutter link measured (.531 ") from where it rides on the bar rail to the highest edge of the cutter, and the difference is exactly (.025 "), so that must be the factory setting. I used a Vernier Caliper, accurate to ( .001 "), and used most of the cutter link, and most of the raker link holding the calipers parallel to the links.
I am still not sure what the difference would be using different gages, but I am also sure that my hand filing or a local sharpening shop that grinds chainsaw chains is not going to be that accurate, anyhow I guess it is possible to get an in-accurately made gauge, since most of them are kind of crude design. Also over time as you flat file on the gauge to remove the tip of the raker to the correct depth, I'm sure you could change the depth gauge by a thousandth or two with wear from filing.
Anyhow, Just some more thoughts!
