    Default Very early K&T spiral universal center (dividing head)

    I acquired this dividing head at an auction for not very much money. I had no idea the maker until someone on PM pointed me to a cut from Catalog No 19, circa 1917. It seems to operate just fine. And besides a couple missing oil plugs, it seems fine. And itís over 100 years old!

    To be honest, I donít know if Iím going to keep it or unload or scrap it. Itís probably worth more at scrap prices than I paid for it. Or at least close. And there Doesnít seem to be a lot of information out there in it, so I doubt the machine this was paired to is in use today. Are there any others out there? I couldnít find even pictures outside of an illustration from the catalog.

    If someone out there has an interest in it, Iíd be happy to work something out. I hate the idea of scraping it, but itís taking up space and my shop is very small.

    Here is the catalog from about 1917 - thanks to Greg Menke for hosting it for me

    http://pounceatron.dreamhosters.com/...a1917-port.pdf

    Had a head like it, gave it away years ago

    Appears to have the extra shot pin ON BACK of index plate (like the one I had) - maybe for Differential Indexing?

    Don't scrap it. Hopefully you and rabler can come to an agreement, I've seen much worse saved.

    Very cool. My guess is they are from a similar era. The difference being the one I currently have can be driven by the table feed. I think yours is the "Universal Center"

    Similar era and design features but not the Universal head as shown in the image.
    The one I have swings 6 & 5/8" and weighs in at a trim 28 pounds.

    I need to get a scale and try and get a weight. It's got to be at least 80-100 pounds.

    If your Spiral Universal head swings 10" it will have the #10 B&S taper in the spindle bore and weigh 155 pounds.
    If the swing is 12" the head will have the #11 B&S taper in the bore and weigh 240 pounds.
    I wonder if that weight is with or without a K&T supplied chuck?
    Thanks to John Oder & Greg Menke for the link and hosting.

    Here is a tailstock that swings 10" and is similar to the K&T in the image.

    It does have a 10" swing, and according to my bathroom scale (don't tell my wife ) it's 113 pounds with the chuck. Maybe the 155 pound specification includes the tail stock? Or my scale has been lying to me all these years!

    I have decided to sell it and have a buyer pending. It's just going to take a while for us to connect.
