16” SB Spindle Taper

I think I have a caliper that that I can reach in and measure the taper.
Otherwise will try the MT #3 taper. The #5 has plenty of metal to work with.
Will turn 1or10 out of scrap first to get it right. Will try turning on my 10” Logan so I don’t have to keep removing the 12” Chuck on my SB
Thanks

If I remember I'll measure mine tomorrow at least you'll be able to compare it to the chart to see where it falls
 
Wow furpo,

Those charts are great. I have the spindle sleeve for my 11" and would like have the collet closer setup but making one is out of my depth at this point, would really like the see the project in progress with the metrology and setup.

This is what mine measures, Large dia. 1.630 / Small dia. =1.483 / Length 3.000 Hope this helps some. Mine is a 1942 South bend single tumbler if that makes any difference :dunno:
