    Was going to reply to this yesterday and forgot. Richard is right for
    one way to do what you want, except for the "T" part. Some people use
    teflon wire for it, and it's not as easy as he says - the wire is
    molded in place and has to be cut carfull so it always goes back. Not
    so hard, but he makes it sound easy ;}. But that's not going to get
    you a "T" hole or an "X". My real suggestion is to mold the piece,
    cut it normally, cut the rubber off that goes into the holes so they
    leave a depression, and then drill it after. Otherwise you have to
    cut all 3 or 4 pieces so they meet neatly in the center - you can
    pull each one out, but you just can't pull a "T" shape, obviously.
    The problem with that is that a formation like that is hard to get in
    place when shooting, and the thinner and longer it is the more the
    rubber will float out of place when shooting waxes. You can use
    Richard's wire idea, but again you'll have to have 3 or 4 wires
    meeting in the center, and you can get the same issues of blowing out
    of place in shooting waxes, but much less than rubber. I would leave
    dimples of rubber for the holes and drill it after - making it in one
    (2x1 part) or two halves (1x2 parts) and assembling after is the
    truly proper way to do it, but that's much more complicated.
