    Default ER32 holder for 3/4" lathe square mount?

    I am looking for a tool holder that will fit my new to me, well used TL2 with the 4 position auto change post. I would like to use ER32 holders but can not find anything available online for them? I am sure I am just using the wrong terminology.

    Looking for somthing like these:

    Those look like boring bar holders with ER adapters sorta stabbed in there.

    I would probably weld a chunk of rod or DOM to a piece of 3/4" square CR, bore a hole to fit the ER thing and drill/tap for a setscrew.

    I think what you want are called "collet blocks"? . Google ER32 Collet block and see if that is what you are after.

    Can you buy or make a morse taper er35 collet holder? A morse taper qc tool holder is common. Or a boring bar holder and get an Ar35 with a straight shank.

    I bought a square and hex collet blocs for an ER40 collet set. Just like the common 5c sets. Stumbled across them on E-Bay a few years ago. They were pretty cheap. Don't recall the seller.

    One of our own members fabbed up a batch of hex and square for ER40 that was an improvement as to clearances. Several of us took one of each. Nice goods.

    ER32 is easier.

    What Garwood said.

    Be aware that the common straight shank ones are often Metric at the best price-points is all.
    BFD. Not that boring a block of steel cares.

    Just make it to fit wotever you need it to fit.

    Most people use turret bushings in a CNC lathe. You just make them. I have never seen a laydown style turret that small though. Seems like a very primitive turret.

    If I needed to hold, say, a 3/8 drill bit in that turret I'd mill a 3/4" tang on a chunk of steel and use a drill chuck held in the lathe chuck to drill and ream a hole for the drill. Add a setscrew and done.

    This might be what your looking for? ER32 1" ER Collet Chuck Tool Holder with Straight Shank It's an example and not an endorsement for the supplier though.
