4 inch ball gate

Thanks first to PeterH1500 for a great design. This remix only changes the tub connectors to allow for US standard 4" connections, which I needed for my woodworking shop.

Follow directions from original. print

1 ball
1 lever
1 bearing
2 tubes, either male or female as needed

original design calls for metric screws. if in US, #8-32 x 3/4" screws work for all locations except the lever. there you can use 1" or ream design a little to sink screw.
