    In looking at the picture of the arch I wasn't aware that Pittsburgh-Des Moines Steel was involved in it .PDM was a oil tank,water tank builder that sold out to Chicago Bridge and iron .Funny according my references CBI only ever built one bridge .

    You can see the arch from miles away on interstate 70 going into St Louie .

    Interesting thread .I think we get caught up with modern methods which just use the same laws of physics similar to old school methods that have been around for thousands of years .If it worked then,it will work now,nothing has changed .

    If you are going to case harden a bolt first heat it up to cherry and toss it in a can of brown sugar .Of course it will catch fire .After it cools heat it up to orange and quench it in oil .Sugar is c6 H12 o6 .You burn off the hydrogen and oxygen and the carbon infuses into the steel so it can be hardened .You could heat and quench mild steel a hundred times and it will never get harder < that trick BTW is older than the hills .

    There is a local guy who started a reclaiming,recycling place .He has a giant tub grinder and a regrinder and will take about any woods type product .He lays this stuff out in 1000 foot long rows and turns them with a John Deere 450 dozer then sells bulk mulch .He's doing okay with it and the tree trimmers or anyone has no dump fees .He's also got a small herd of buffalo and elk .

    A lot of being able to find odd ball stuff is just related to a persons environment . In my case it's not that I'm all that smart but I've worked around industrial machinery all of my adult life .Now if the subject was smart phones or some such thing I couldn't touch my azz with both hands .One mans poison is another mans meat they say .;)

    Those shock mounts might be okay unless the rubber has deteriorated .We use a similar design at work on high pressure piston pumps used to cut the flash from crankshafts .Around 8,000 psi with 75 HP motors . For that matter although I haven't checked McMaster -Carr might have something like that .

    You know it's kind of funny how certain things are illegal until they figure a way to tax it .Doesn't really make a difference what it is .

    I haven't seen them all but what I have on knife bolts were all socket heads .The tannic acid from oak chips can just play a tune on high carbon steel bolts .Which is why I suggested some type of anti seize compound to be used .Money and time well spent .Fact it might be money well spent to just replace knife clamp bolts on a knife change in the long run .These things can be a black hearted whore at times to work on .Been there several times,skinned knuckles and all .

    For general info grade 12 (metric rating 12.9 )only exists on metric fasteners which is about the same as grade 8 SAE .Depends on the reference .I think one rating on 12.9 might be 175 PSI tensile while some grade 8's are 150 thou .Then again it just depends on the reference used .That said it would take a lot to break or have failure on either one .

    The millwrights at work use the DeWalt impact wrenches .For no larger than they are they do have some amazing power .I don't own one myself but do have a collection of air impacts from 3/8" to 1 inch .The 1" doesn't get much usage but my heavens does it take some air . In addition I have a couple of reduction right angle drive air wrenches.No impact but they could very easily break an arm .

    Just a thought on that Morbark ,not trying to be a smart alec but by all means use some never seeze on those knife bolts .I drilled the bolts out twice on Toms machine and it's a black hearted beech to do .Those grade 8 cap screws are hard as twice hammered hell and it takes a solid carbide bit to do .
