Topic tags/keywords: arbor size tablesaw question

Ok so this is my first post but i have been reading and learning alot from this website for a while now.I have just bought my first cabinet table saw a powermatic 72.This table saw is awesome(did n’t realize that i had been using junk all along with my older contractor saw till saturday when I cut my first piece of wood on it).I just have a question about the arbor size.This saw has a one inch arbor which is very hard to find a blade for at your local hardware store not to mention the added cost of a twelve or fourteen inch blade.Then add a dado set and your really talking about alot of money.I was thinking of taking the arbor off and having it turned down to 5/8 at a local machine shop.Would I have any problems with that route or just better off buying more expensive blades?If the latter then where is the best place to buy dados with an one inch arbor without spending an arm and a leg?

I hope your joking about machining that arbor ! I dont know why you would be having a problem finding blades for it, unless your just looking at one local store . I certainly wouldnt do it to accomidate a dado set of all things. Nice saw by the way, but I would rather see you sell it to some one who would appreciate it rather than screw it up. JB

Sell it to a cabinet shop that can care for it and use the proceeds to buy something you’ll be happy with and able to find off the shelf parts for.

Ok I see that I might have hit a nerve with a few people.First of all I am very happy with the saw and I do have the ability to care for it(and I also appreciate it).Second of all it was just an idea seeing as i cannot find one inch blades at any of my local hardware stores(not just one store but all of them).I do not have a problem with ordering blades online and keeping several around.The main reason for asking this question was for a dado set because no matter how hard I search I cannot seem to find a dado set for this saw(at a reasonable price).So far I have found one online dealer and they are close to $400.Any help would be appreciated.

Just an idea but if you are up to machining the arbor how about machining the dado set instead?

Get a decent dado that will last a long time and have someone open it up to 1”.

You can re-drill arbor hole on the saw blade. Many saw sharpening/repair shops do it for $15-25 per blade.

Those hardware stores can probalby order blades for you. They seldom stock everything that’s available to them. You should also find anything you want on the internet.

Lots of 1” arbor blades available on ebay, for cheap.

Don’t turn it down to 5/8”. Foolish and you’ll ruin
the saw’s resale value.

I’ve not found blade boring to be anywhere near
$15-$25 per blade but it has been awhile. I had
a dado set opened up some years ago for a saw
I had with a 30mm arbor and it was probably $45
for the job. I had some other work done at the
same time so they might have done it cheaper
than normal. The shop had no reason to alienate
me by gouging – I just went in there and said
I was a pro and bought a blade from them too.

You can get a special kind of milling cutter and
do it yourself on a drill press. My brother who was
a machinest got me one to enlarge 5/8” holes to
3/4” for a saw I had. It worked great but I ran
it too fast once and smoked the carbide.

That was my first thought chuck,I had actually talked to a machinist about machining a blade set to one inch but he advised me to machine the arbor instead.
I had never thought about a sharpening shop doing it Ill make some phone calls tomorrow and see if I can go that route.Thanks for the ideas.

Also there are Onrud closeouts on ebay and they are
really great blades from a top-shelf maker with little
branding as a saw blade maker (onsrud is known for
milling cutters).

I am lost. The “standard” bore size for 12” and 14” blades is 1”. Unless you are looking at 10” blades most of a small suppliers 12/14” stock should be 1”. The difference between the 10” and 12” is probably no more than the cost of having a arbor hole enlarged at a saw filer. I suggest getting a glue line rip and a crosscut Onsrud on eBay, the pair runs ~$60 with free shipping for 12” blades. There aren’t many closeout Onsruds left on ebay so I suggest you hurry.

PS as others have said don’t even think or turning the arbor!

Have your say...
