The original Magna coupler has a 5/8" hole all the way through the centre.
Mounting the jigsaw and lovejoy connectors on the 10ER without the spider reveals that the spindle protrudes into the space where the spider is.

The solution was to was to remove part of the centre of the spider (I used a 5/8" Forstner bit).

The spider at the top of the photo is original the lower one has been modified.
How about a collar behind the left half of the coupler?

That would work if you have one sized appropriately (bore and outside diameter). I don't.

I have thought about the collar. It will not make the shaft shorter to eliminate the 'interference'.
So the dimple will still be necessary.
Not being on a first name basis with a 10 JS, does it lift off straight up or 'out' and up/off? I assume the latter since the original coupler was solid rubber center with metal ends.

It lifts out and up. But you still have to extend the quill as well (or, in the case of removal, retract it). When the jigsaw is installed, the end of the quill housing is extended to seat in a chamfer in the lower housing.

My problem is that you can't seat the hub all the way down on the spindle. And with the tapered flat on the spindle, they eventually work their way back on the spindle and come apart from the spider and other hub. I finally wrapped duct tape around the hub-spider-hub assembly to keep it from coming apart.
There is an original
10er jigsaw coupler just listed on Ebay.

I have an original coupler, but the glue between the rubber and metal broke down over the years and the pieces came apart. I'd be a little concerned about the same thing happening with another. Time does take its toll...

Time takes its toll, please have exact change.
I have not tried it myself but someone on the Shopsmith 10er forum said they had used the larger size Lovejoy connector (the ones with three lugs on each hub) that have center less spiders and/or spiders that wrap around the outside of the hubs available for them.
