B&S taper arbors show up on EBay and they do not go for a premium. Bob is right. Get a proper taper arbor. Don’t regrind that indexing head.
I picked up an old Burke model O bench miller. It took a B&S #7 arbor. I found a couple of arbors for it on the cheap by searching EBay.
I think one of them was a double taper collet chuck which even came with some collets. Anyway, they are out there. Not totally obsolete in my opinion. Tools-n-gizmos and Wikipedia “machine tapers” will give you all the specs to see which size you have.
Google eBay brown Sharpe 7 and/or B & S 7
( or if yours is a #9... replace that 7 with a 9 in your search ). They are out there.
