    Default Columbian L6 JB three blade bronze cleaver

    Hi, folks!
    I recently acquired an old Columbian cleaver "L6 JB". Diameter is 10 1/2" and pitch looks to be around 14"-15". Hub is cushioned, 20 mm smooth bore with shear pin. Fits to some 60's OMC? Hub has spun, so I'm going to fit a 14-spline Chrysler hub and run it in my '71 Chrysler 55 hp/15ft monohull racer from the same era. I would be very happy if somebody could tell me more about this propeller. Name:  IMG_0984.jpg

    dont knowanything about these, but looks a nice prop in pretty good shape.
    hope your going to give it a nice polish up ? it deserves to shine .

    must be plenty of folks out there who know these props, I am in England uk and have heard of them but never seen one.

    I bet ron hill knows about these, or one of his buddies.

    well worth trying it, and if its not enough pitch being bronze could be worked on easy to take it up a couple of inches by a prop shop.
    plus a few other mods and make it a great prop for you motor.
    plus dead easy to keep it polished and look real nice ha ha .

    Cleaned it a bit with 320 grit paper. Next job is to make a press fit sleeve for the hub and put it all together. Truing and a test drive after that. Wish me luck... Name:  IMG_0986.JPG

    That's Chrysler 14 spline hub, going to make it solid. Yes, MSSA is in my plans, hope I will make it to Puumala this year. If I'm lucky, maybe even back to Lappeenranta... =D

    once you get it done, remember to balance it !!!! and a polish up once its done would make it look that bit better.
    also a highly polished prop helps you see if any cracks start to appear.

    Balancing the prop will make it run a lot better and save the life of the hub and your gears too.
    be surprised just how out of balance a prop gets, especially as when new most are way out of balance.

    if you dont have a balance they are easy to make.

    here is what I made recently and works a treat for any prop upto about 16 inch diameter. the cost of this was zero as everything made from old scrap bits lying around.
    you can buy a motorcycle balance that works just like this does, but making your own is better for the wallet.

    simple to make, and when balanced the props do run a bit better.
    got to be easier on the shaft bearing life too ?
