@Janderso, please post a link if you find them online. Pretty sure that's the size I need too.

Will do.
But, since Jacob’s website doesn’t offer them the only set I find is probably shop made.

Sometimes I can’t see the forest through the trees.
One problem with that, all the wedges in the master set are too narrow to fit around the arbor.
Oh wait, I don’t have a 6 set. A 3 is too narrow.

The pic is a 3.

Open them up ! Good to go .

An alternative to these wedges is a clam shell bearing puller which is also great for its intended purpose .

You sound like me Jeff . I have everything in multiples but the hardware store is 45 seconds away . Takes 4 hours minimum to find what I already have .

I knew I had a puller I found a gear puller. Heck, it worked.
Dave, if you hadn't mentioned it I'd be making a set. This took about two minutes to remove the chuck and 30 m inutes to find a slide hammer set and this gear puller.
I didn't know I had a slide hammer

Interesting...

Granger shows the 3JT wedges as discontinued. They are "currently unavailable" on Amazon. And McMaster only shows this thing from Taiwan that says it works for sizes 2, 3 and 6.

Kinda pisses me off how every product photo of those things shows the number 6.

Amazon, McMaster and even Jabobs' own website... Always No. 6

You sure it's not a Number 9, number 9... The Beatles had a thing for "Number 9" ..

in all seriousness, they are all the same, just different sizes, it really doesn't make it worth it to photograph each different one, when the only thing changing is scale.
