I've never heard of a cue that was 1.35" in diameter at the fattest part of the cue, which would be at the very end of the butt. That measurement then tapers down to the joint, so in the middle of the handle it would not be 1.35". If the joint measures 0.840" and the end of the butt measures 1.35", and the butt has a straight taper from one end to the other, then (1.35 - 0.84) / 29 is the change in diameter per inch, which is 0.0176" change in diameter per inch along the length of the cue. If the middle of the grip is 10.5 inches from the end of the butt, then the middle of the grip will have a diameter of 1.35 - (.0176 * 10.5) = 1.165 inches.
If the end of the butt is 1.30", and the cue has as straight taper, then the middle of the grip will be: 1.30 - (0.0176 * 10.5) = 1.115" in diameter. Most cues made today measure 1.25" and below at the very end of the butt, and Becue makes a 1.21" butt. For production cues, Viking makes a 1.30" butt. I'm not aware of any custom makers that will make a 1.30" butt, much less a 1.35" butt.
If you like a house cue, see if you can find a custom maker that will cut one in half and add a joint.
