BobP,
I do not insert the dryer with lures attached. The wheel stays fit on the axle of the motor. I take a lure holder, clamp the lure in it, topcoat it, then I turn off the motor (if there is another lure for drying), insert the small stick (handle) of the lure holder into the hole of one of the 4 rubber discs on the wheel, then turn on the motor again. For the first lure which I put in the dryind wheel, I have a "false" lure on the opposite rubber disc, to balance the weight on the wheel. Also, I put a false lure for the 3rd lure to dry. Or, I would better say, I will do that if I ever put 3 lures at a time to dry, but I don't think this will be the case, because I don't have more than 2 lures at once on the wheel.
When I insert the lure holder, I must keep the other hand on the wheel, opposite the lure, because the wheel is flexible, and otherwise it would flex or move.
The drying wheel has 3 parts, but I see no reason why I should not glue the linking part to the disc. What I like about this dryer, is that it is very easy to assemble or dismantle. It takes me less than a minute to stop the drying wheel and put it in a wardrobe.
