Grab the marble from the top (suction device of some type), and dip only the lower 1/4 or 1/3 of it into the glue, then immediately place it into the recess in the wood. Glue never gets on top of the marble, thus never needs removed. Or am I visualizing things wrong? I'm thinking the marbles are setting in shallow "countersink" type holes, with 3/4 or so of the marble sticking out on the "good side" of the board. If the marble is setting much deeper in a nearly full diameter hole, and is inserted from the back side, then I agree that getting glue off the bottom of the marble is a problem. It seems like in that case you need to apply glue only to the "equator" of the marble. If using a hot-melt type glue, grab it from the top as before, then move it to a glue dispense station and orbit over a stationary glue extruder nozzle, then move to the board and insert. If gluing into a countersink, the nozzle could point straight up, and you would orbit over it. If you want glue on the equator, the nozzle could be near-horizontal, and you would approach it horizontally, then use the spindle to rotate the marble one full turn while dispensing. In either case, there might be an advantage to holding the marble in the stream of a hot air gun before applying the hot glue. -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
