    Default Haas Spindle Extension Cap RFQ

    Hello,
    I am looking to buy 10 Haas lathe extension caps. The old caps aren't made anymore and we would have to upgrade to their new system that isn't as good.
    The failure point is the 10-24 thread and gorillas tightening them to the point they strip the threads. Walls are not thick enough for an insert.

    The only critical dimension is the 3 1/2-4 8-Thread Series thread.
    6061 material
    External knurling would be nice.
    In the photo the part has an opening to feed barstock though but it would be better if it was closed.

    Attached is a link to my drive with photos and a basic CAD model.
    Let me know if you need any additional info.

    Or we are running into some machine limits and working around those maybe more expensive than getting someone else to make them for a fair price.

    Why not drill and tap a new hole next to the old hole, perhaps one on each side?

    We have done that on most of them. As we move the holes closer to the edge that need more force to close and thus strip out faster.
