so I got a new/used dirty rock saw, actually my first ever, blade has a big notch in it so it needs to be replaced, took it apart got the arbor/blade assembly out, but can't get the blasted nut off. WD40'd the crap out of and it's sitting, um so which way to I turn the nut, I certainly don't want to make it tighter, do I turn it the same direction as everything else in the work? Left? I just want to be darn sure before I go make it worse.

Turn it in the same direction the blade turns when in use.

Facing pretty much any manufactured machine from front, nuts on the left will be left hand thread and right side right hand. The only thing I've found not so is old wood spool polishers and the newer Gy-Roc saws. Gy-Roc went from a left hand threaded shaft to a 1/4" - 20 center drilled threaded hole. According to him right hand threaded cap screw works fine. Cheaper to make and no left hand nuts.

ancient encrusted grit nuts are some of toughest to crack No matter which way they turn
I had to angle grind off the nut on the saw I refurbished that was after I drilled holes in it oiled it for weeks and had a huge breaker bar and enough weight to make grown man shudder good luck! Ed

heat it up with a torch, then while it is still hot pour ATF fluid on it. When it cools down you should be able to get it off.
Good luck............Tony

I soaked it in wd40 and let it sit over night, I then put a 1" ratchet one it and hit the handle with a heavy rubber hammer and finally it loosen up, had the blade in a vise too.

When you put a new blade on, do what I told one of the gals to do with set screws the other day. Go to the auto parts store and get a tube of anti seize compound. Clean the arbor threads real good and put a thin coat of the compound on them. It should solve any future problems of nuts freezing up. Be warned though. The stuff is hell to wash off your hands. The more you wash, the more it spreads around your flesh.

Anti seize, Never Seize are graphite based products. They really work. No longer legal for plumbing work so mostly just found at auto parts stores.

Any manufacture who assembles metal to metal items that have to come apart should be required to use this product or be shot! Especially in wet or corrosive environments. Should be installed on pulley & bearing shafts. Works good on other moving parts on your saw. Every mechanic has a bottle of this in his tool box. Like Don said, not only get any on your skin but avoid getting on your clothes too. Otherwise your wife will be so pissed off, you'll be doing your own laundry from then on. I speak from much experience! Permatex & Loctite makes this product which is available at all auto parts stores. LarryS

That be the stuff ! It should be pointed out that unless you're rebuilding masses of equipment, a bottle that size will last the average lapidary a lifetime. Probably the next generation of rockhound too. Just a tiny bit goes a long ways.

went to an auto parts store close to where I work, first he showed me locktite I said um no I actually want the opposite of that. They had a small tube, like the travel size tooth paste tube for less than $4.00
so basically any moving parts would benefit from a little bit of this stuff?

Yep, any part you have to take off. Think the list price of this small jar is just under $5. That's ok, the little tube will last you forever. A little dab goes a long ways.
