    Anyone recognize this Delta/Rockwell drill press?




    Trying to figure out how much HP it has and if I can set it for low RPMs. I'm pretty sure I can fix it up.

    and this is its current condition..

    What's on the motor plate? That should tell you the HP that it came with. You can measure the pulleys and determine the drive ratio. Use that and the motor RPM to determine the lowest and highest bit RPM.

    Good machine, I have 2. Came with .5 HP and 4 speeds ~250 -~1100.
    Had mine reworked.

    I have that same drill press, manufactured some time in the early 70's. I think mine is 1974. 4 speeds/pulleys, but I am not at home now to check the motor HP. Good drill press but no hand crank to change the table elevation. Have to use the muscle method; not fun with my auxillary table mounted on it. Yours should clean up nicely and work great.

    We used to have one just like that where I worked. IIRC it had a 1/2 hp motor. Good machine! Sure would be nice if it had a crank up/down table. That thing's murder on your back.

    That's a nice find depending on price of course. You can shop-make table elevation schemes from simple to complex, it just depends on time and money- what doesn't?

    Here's a couple of links to review for ideas:
    Also, a used car jack, the scissors lift type can be employed as well.

    Don't forget too, you can use a jackshaft combo to get the speed range anywhere you want it to be.

    It looks to me like the mount is missing from the motor. If so, you will need a motor for it. I would also find out if it comes with the 4 sheave pulley for the motor. Those can be rather pricey.

    That motor sits in a cradle mount. The cradle is missing. You will need a cradle or a different motor. I'm guessing the step pulley is missing, too. Keep these things in mind when determining a value on the drill press.

    Could the step pulley be on the spindle or is it always on the motor side? I'm thinking it may be worth about $25??

    There should be a step pulley on each shaft to get the best speed variations. One is right side up the other is upside down. With two stepped pulleys you don't have to retension the belt when changing speeds.

    Well I got it for $40. It had been lying in the driveway for a few weeks and had gotten rained on a few times. When I asked if he had any of the missing parts he says oh yeah....goes to the trash can and pulls out the other stepped pulley!!

    THe spindle travels 6 inches and there's no play in it. However when you allow the stop screw to stop the spindle, it pulls to the right as it stops.

    Heres some new photos

    Some things I've noticed so far....

    Model No. is 15-665
    Pretty sure its called a 6+6, I've downloaded several manuals from vintages machines but none of them have the exact model number.
    Theres a black tensioning wheel that wont turn
    There is a place to put machine oil but it just dumps into the cavity that contains the spindle.


    Getting the motor running will be the first step..
    Not sure if it will run on 120v...says 208-230/115v
    all the external wiring was not included. (power cord and between switch and motor)
    Looks like I'm missing the motor junction box
    I found a used Baldor 1hp motor with mounting bracket on craigslist for $35...may be easier just to go with that. Its 220 only so I'm going to pass.
