I find having auto control of ball direction counter intuitive to what the purpose of the machine is for. I.e. drilling the same type of shot again and again.

[@doremisol4760]

Glad to see your nice diy ball machine.

[@mattharvey8712]

Bravo......clever........now make adjustable ball size........speed on each wheel......maybe third wheel......cheers

[@michaelmariti999]

Great machine! Can you make a video tutorial on how to build this?

[@Swenser]

I too am trying horizontal mount. Im working on ball hopper mechanism now and think ball jams is the hardest thing to contend with. No.2 I found it hard to find matching wheels and couplers but eventually is ok. Thats the two hardest things i think.

Hi, great job on the quality of the construction. I'm currently working on my own (vertical orientation) and I would like to have more info on the material of the wheels and how did you balanced them so well. Also what kind of motor coupling did you use?

[@balapadmanabhan1085]

The wheels are custom made of nylon rod and then I had a cobbler stick a 8 mm rubber sole over it

[@andreasrist9578]

Hi, cool machine. Where did you buy the wheels?

[@avataronline9037]

Before getting this far with the current wheel . I tried at least 10 different materials and sizes. The wheel was custom made . Just wanted to know if you tried any wheels available in the market so far. At what stage are you with this project? I will surely help you out; so that you don't have to go through the same trouble.

[@Swenser]

Also wondering what happens before switch on when there is a ball already sitting at spinning wheels. I'm guessing the only solution is manual removal of the ball, right?

[@arsenasaturyan3506]

Hey, nice project. I have one point, why did you put wheels on the side of the ball? you won't be able to do top and back spins

[@balapadmanabhan1085]

My newer model has a vertical orientation . Thanks for the observation. Do you have one that you are working on?

[@analopes-rk2bs]
