    Default Another CSM setup

    Howdy y'all. This is my current setup: GB 44" double ender with aux. fuel tank and winch. My adjustment clamp for the powerhead side
    uprights are beginning to slip some. I am going to add locking collars to the uprights.

    Cool setup mate
    That log should have some nice grain and figure
    Was it 'firm' to mill or did it slice like butter?
    Is it Ash too?

    Ash was hard as a rock! Did a little more sharpening on these logs. One of the pictures I put some bar oil on and it really brought the grain out! Alot of ash on the ground and dead standing timber. The Emerald Ash Borer has wreaked havoc throughout the South.

    Apparently wacks into Elm and Walnut too
    And will kill large standing Ash trees in around 4 years
    Nasty little critter/bug
    Good to see you salvaging the logs
    I take it the larvae munch on the sapwood
    OR do they penetrate deeper into the heartwood?

    Here in Oz Ash would be considered a relatively "soft" hardwood.

    On a comparative scale
    Ash is nominally rated at 1300 lbf
    Tasmanian Oak (widely used here in Oz) is 1350 lbf
    Hickory and Pecan are about 1800
    Jarrah also widely used by Aussie furniture makes is ~1900 (I consider this a moderate hardness timber)
    Osage Orange is about 2000
    The most common timber I mill is Spotted Gum - this is about 2500 lbf. This is a weed in my state and commonly grow s way too big for suburban suburban yards which is why the tree lopper I work with has a log of these to take down.
    I have milled some Red Iron bark and that is about 3000 - now that was really hard and has the added complication of a resinous bark that picks up and retains grit - does nothing for chain sharpness.

    Is this normally the case when you mill Ash?
    Or is the log simply 'harder' than normal?
    That hardwood log is quite big and gnarly too
    She'd be firm cutting I reckon
    Have milled many species of Eucalypts over the years...and a few 'tough' exotics
    That's why I love milling 'Red Cedar' LOL
    That Ash is very figurative though

    Tallowwood is around 2000 and Brush box 3000
    I have milled some very large examples of both these species
    The Brush box was around 1500mm d.b.h with a short bole...very very firm wood!
    Probably much higher rating than 3000 i.m.o
    Tallow too can be very hard as well
    Particularly the big old paddock grown ones which tend to buttress
    Likely greater than 2000
    Age/size /provenance of the tree really makes a difference to hardness/density of the timber

    Yeah I forgot Iíve milled quite a few brush box. Like Tuart , some of the BB I milled output the odd spark, apparently itís from small silica grains deposited inside the trunk when the tree becomes water stressed. The tree looper told me about this. His crew removed dozens of street BB - those from high ground weíre the most eater stressed and all made more sparks than those lower down. Really knocks the chain around.

    Sapwood maybe 1 to 1 1/2" into it.

    I had let it season a little to long.
    As with any wood, I should have milled it right away. I did anchorseal the ends after bucking it.

    Default Hardwood milling

    Planning on sawing more poplar, sweet gum and hopefully sugar maple before Spring, I hope.
    I will keep an eye out for Hickory, I like it. Oh yeah, white and red oak ad well!
