    Default Indexer Question

    The max diameter for the Desktop indexer is spec'd at 3.6". Is there any reason why the indexer could not be lifted by 1/4" so that a 4" diameter piece could be machined?

    I believe it's spec'd as a measurement between the center and the table. If you want more diameter, you'll have to jack up the indexer and tailstock as you've indicated.

    One thing that makes tiny clearances dicey is that you have to perfectly situate a round blank in the indexer. If you already have a lathe, that should be easy.

    I believe they spec diameter, not radius. From the Shopbot website:

    Yes, the measurement from the center to the table TIMES TWO. I apologize for my mistake.
