I have a brand new BB6 ER32 spindle. I thought that there was an internal stop for pseudo quick tool changes, but it looks like I was mistaken. It looks like what I really need is the old style 3/4-16 headstock with ER16 adapters or solid tool holders. If anyone with an old style spindle and a couple tool holders is looking to upgrade to ER32, I'd be thrilled to trade. If you have enough tool holders, I'd even be willing to throw in some of my Maritool ER32 collets as well.
