I used a broken shovel handle and the seat back.  It worked surprisingly well, several times.  Make sure the vinyl of the seat can handle the handle end though.  Don't want new cracks.  Crack bleed screw, press brake pedal down with shovel handle, prop against seat back, close bleed screw, release handle.  If the clear tube is set up with an upward curve you can see if any air bubbles came out.

Get a endoscope camera from Amazon for $30, there are 10 ft. And longer camera leads. It’s blue tooth. Set it up watch your caliper or WC on video and watch for bubbles. Used this with the speed bleeders. One man job and you can watch the real time video. Works great. Cool camera, you can use it for almost anything…

You'll love the speed bleeders, I work alone too and they make the job so much easier.

I wouldn't have thought of the camera. Sounds like a great idea.

Did you see fluid coming out of the calipers when you bled? Did you bleed the MC?

Yes, some, but no bubbles. I did bleed the master cylinder.
