Arbor Nut for a Saw Stop PSC Table Saw

[Mr. Ree]

My bad.  [embarassed] I dropped the arbor nut into the bowels of my saw, never to be seen again.  I contacted Saw Stop and ordered a nut.  Received same, but it would not thread onto the arbor screw without excessive force being applied to the wrench.  I confirmed with Saw Stop that I had the right nut (I was told there is only one size for all of its saws).  To Saw Stop's credit, they sent me another.  Unfortunately, same problem.  [crying]

Upon closer inspection, I note that whatever the outside of the nut is coated with (presumably powder coating) was also applied to the threads.  That, I assume is the cause of my problem, because the original nut's threads were not so coated.  I received the specs for the nut (5/8-12 Acme thread) but cannot find such a nut on the internet.
 
Does anyone know of a source for this nut (uncoated, of course)? 
Or does anyone have a suggestion how to remove the coating?

- we're all mindful of dropping that Arbor Nut into the bowels of the table saw. If a second attempt to retrieve yours is still unsuccessful, I would take a real close look at the "coating" on the replacement part you refer to.

Could it be a cosmoline type corrosion preventive packaging coating which can be peeled/ removed with a sharp knife?

I have never seen an arbor nut coated with anything intended to remain while in use. Ask Saw Stop support if the part comes with a coating intended to be removed before use - most likely.

There's always aluminum foil, two thin dowel rods and a 350degree toaster oven. Pliers and leather (welding)gloves. or try to burn it off with a MAPP/Propane torch outdoors.

let us know the solution / answer

Thread doesn't make sense.  Acme threads are for power transmission/motion  (moving flaps on airplane/etc), also 5/8-12 isn't a thread pitch for Acme threads.

I dropped the arbor nut on my PCS once.  I found it in the dust collection hose.    Suggest you look there.

for a few dollars you can get an extending magnet on a wand and go "fishing" for the lost nut.

[/quote get a magnet that has a hole and a mason line and drop it down. Monofilament Fishing line works too. Tie the knot end well so you don’t loose the magnet auto parts store sell 12” + flexible magnet extractors. Have fun fishing . I’m not sure if I would leave it there. Have you tried turning it upside down like a piggy bank and jiggling it till the nut falls loose? Maybe not a great idea.

As far as I can remember, the PCS has a short 4" dia. hose connected from the saw shroud to the exit hole. Disconnecting the hose should reveal where the nut has gone (either in the hose or stuck in the plastic shroud). 

 

[Mr. Ree]

Thank you one and all for your responses. 

As for searching for the nut I lost, I did open up the right-side cabinet and thoroughly searched without success.  I also disconnected both ends of the hose.  Still no luck . Haven't tried the left-side cabinet because I do not see an opening to it.

I have searched on the internet for a nut with the specs. I was given by Saw Stop and only found a nut that size (5/8-12) for an arbor nut for  Jet saw.  Unfortunately, I haven't been able to determine if it has the same height and width, and it is obscenely expensive (i.e., 4 times the cost of a Saw Stop nut).

I am still hoping someone can offer a suggestion for removing the coating.

Again thank you for your responses.

Regarding the coating, I can only describe what I see, and there is no doubt that the threads are coated with a black substance that appears on the outside of the nut. I know cosmoline. That is not what I seeing.  SawStop claims the threads are not coated, but I suspect no one has gone to wherehouse and looked at what they are shipping.  The metal of the nut (inside and outside)  is not "in the white" as it's called.  Initially, I thought it was paint, but I haven't tried a form of paint remover becasue it looks and reacts (i.e., impervious to scratching) like powdercoating.  I am afraid to try heat because I don't want to damage the strength of the metal.  Keep those suggestions comin' [smile]

[big grin] [big grin] [big grin] [big grin] [big grin] [big grin] I found the prodigal son!  I shall have a fatted calf for supper.

It somehow had attached itself to the back of the slanted bottom of the right-side cabinet door, which is at least six inches above the bottom of the cabinet floor - where I was looking.  I forgot a rule of tracking: "Always look up"

My profound thanks to all who took the time to respond.

P.S.  The original nut is not coated like the replacement nuts.
