Title: D009 18" 20" oregon powermatch 3/8 bars
Post by: Cut4fun on April 11, 2016, 03:37:22 pm
Over the weekend I was comparing D009 18" 20" oregon powermatch 3/8 bars  for a couple guys.
When you have them side by side there isnt much difference in them length wise.  72 drive link to 68 DL chains.   Wonder why so close?
 8 more DL's down to 16" 60DL.

That's a normal observation - the 68dl 3/8" Husky mount bars simply are longer than "called", when the bar manufacturer follows Huskys specs.

64dl ones (also called 18") exist as an alternative, at least in small mount (K095). These really are 17" bars, like the 72dl bars called 18".

The "called" length of a chainsaw bar very seldom is accurate - and shorter than called is much more common than longer. Those 68dl bars represent a very unusual exception.

I just thought it was worthless having those 2 bars in D009 large husky mount so close together in length. I will take a pic later.

Not talking the small mounts in 64 66 etc.

The European seem to go for shorter bars 13, 15, 17 inch.  It may be that they are metric?

I've noticed that as well. Too small a difference and 20" loops are easy to find.

Not really, as those lengths look pretty "uneven" in metric, being 33, 38 and 43cm in theory.

The most common bar lengths here is 13" and 15" in .325, and 15, 18 and 20" in 3/8". 16" is uncommon, but my favorite on 50 - 60cc saws.

18" called bars in .325 (72dl) really are 17" bars, as are 64dl 3/8" ones, but that isn't a European specialty.

Also as usual, 3/8" lo-pro/picco bars are an inch or more (mostly more) shorter than called, as are Stihl .325 3005/A074 bars.

Mainly the options are the same as in the US, except for the 15" vs. 16" thing, where I prefer the US "line" (16", not 15").
