@Nike00 - She only has use of one arm, and that is limited. She can't reach out onto the table. Picture the two kids in wheelchairs who do the Shriner's Hospital ads, then imagine they can only use one arm.
But what you show, on a wooden base, might do the job. She can manage that weight, which is about 1/4 what the brass one weighs. The way I would expect her to use it is have her opponent place it for her and then might scoot it around a little with the cue. I could make something like that, but you seem to have thought the cue rests out so I could probably buy one and make a base for it.
She did make some creditable shots with me holding a bridge for her. She almost beat me! It helps that I had not played pool for about half a century. She'd never tried a bridge before. She rests the cue on one shoulder and uses that arm to move the stick.
Her usual technique without the bridge is to bat the cue ball with the cue stick, kind of like baseball, which gives about the precision you would expect.
She also bowls, using a ramp. The important thing is she loves doing both.
@Nike00, your face looks a lot like a fellow with your name who works for NEC in Canberra, Australia (on Facebook). If you could accept messages there, that would work. I don't see a message app on this forum. I'm in the US. No rush. The young lady is going back to college tomorrow and I can give it to her on her next break.
