The key to attaching and detaching guitar cases to Tukhemin is the top right peg. It can be loosened and tightened quickly and easily by using the wing- nut. Once loosened, it slides left and right in the slot. So to attach a guitar, banjo, or whatever case, loosen the wing-nut for the top right peg and slide the peg to the right. Set the case in the embrace of the other three pegs and then slide the peg to the left until it is snug against the case. Finally, tighten the wing nut. To release the case from Tukhemin, reverse this procedure: loosen the wing nut for the upper right peg, slide the peg to the right . . . slightly is all you need, and lift the case up and away.
