    New Hermes Manual Rotary - I want to drag

    I have recently purchased a New Hermes Gravograph IM pantograph engraver. That is one of the smaller manual units. It came with a rotary belt driven spindle and I want to diamond drag.

    I have seen on ebay a listing that has a diamond stylus that is the correct fit @ 1/8" x 5" My question is can I use that to do diamond drag engraving without the motor.

    Second question. Where can I get plastic caps for my spindle.

    thanks Marty

    More than likely that is the right diamond for drag engraving. Obviously, you should test it on some scrap before using it. You would not use the motor.

    I'd be more inclined to buy from Johnson Plastics or one of the manufacturers such as Antares. That way you're sure to get a new one and one that is intended for general purpose engraving rather than one for calligraphy (doesn't work well).

    Thanks Mike. I will go ahead and try the 1/8 diamond. The seller has other items I am getting like belts etc.

    Do you know where to get the plastic spindle caps, aka nose cones, the thingy that prevents scratching of the piece as you engrave?

    And I am planning to color fill ABS plastic (thermoformed post engraved) and want a recommend on what tape to use. Rotary engraved ABS.

    thanks marty

    The nose cones aren't usually plastic, most are stainless, although I have a large nose with a vacuum attachment that's Delrin... the collars that hold them on are nickel brass, and they're not to prevent scratching, they're to regulate the depth of rotary engraving. And the irony is, the nose cones can scratch. You can buy them from Gravograph, but they don't come cheap.

    The 1/8" diamond tool will work great.

    Martin,

    Good place to go to would be Quality One Engravers in Cali.
    Talk to Fred and get nose cone and proper cutters if you did not receive in purchase package.

    1 - diamond drag does not need spindle motor to run (hence drag engraving)
    2 - rotary burnishing requires spindle motor to run and burnishing tool
    3 - rotary deep engraving use nose cone or depth regulator with motor running and proper cutting tool.

    The vacuum the Kev mentioned will do more to reduce scratching than just about anything else. You would likely be getting into more money than you want to spend so I'd advise using transfer paper to prevent scratching. Johnson's has engraver's tape to hold down your plastic material.

    thanks for the info

    Thanks to the replies and info. I have found several places that carry the gravograph brand of nose cones and they make several plastic and teflon styles that don't scratch.

    Here is the link for that: no affiliation

    I have just received a new set of sharp cutters and am waiting on a belt - I am ready to learn about rotary.

    cheers Marty.

    For spindle rotation, it's all sealied bearings, no lubrication, spindle or motor...

    For spindle Z-motion, sometimes the spindle and housing goo up. Usually working some light oil between the spindle and housing will work. If not, you need to remove the spindle from the housing- remove the screw attaching the handle to the spindle- it's been so long since I messed with a pantograph spindle, I forget where the spring is, but there's a spring --remove the belt pulley, remove the snap ring on top, the spindle should just drop out. Clean the housing 'tube' and spindle with alcohol, get them clean and dry. Smear some light oil on the spindle and in the housing tube, then with a paper towel, wipe off the excess until it's almost bone dry, no lube at all is preferable to too much lube, as it just collects dust and makes things gooey faster... Re-assemble.

    ** EDIT ** -- just looked at pics of an IM machine, way different than my old IRX-IV's, totally different pantograph setup, so dropping the spindle should be a simple matter of removing the pulley and the snap ring only...
