Samsung Washing Machine Ball Bearings

This is a great lens hood that quickly clips on and off plus will reverse-mount for storage. It is particularly good for vintage lenses made before such convenient lens hoods became common. One hesitation I had with the hood is the fairly high force to clip it on and off. I completely eliminated this problem by adding 4 grooves in the mount that align with the 4 ball bearings in the hood. The grooves are positioned such that when the hood is at 45 degrees from level, the ball bearings align with the grooves and the hood easily clips on or off. To secure the hood, rotate it 45 degrees to the correct level position. It is easy to align the bearing with the grooves because the ball bearings detent into the grooves when aligned. See the two annotated photos. To precisely locate where to make the grooves, screw the mount on to the lens that will use the hood. Put the hood on the mount at 45 degrees from the correct "level" position for the hood. Mark the position of the hood on the mount or tape them together. Unscrew the mount+hood assembly and repeatedly clip the hood on and off without rotating either until the four ball bearings mark the aluminum mount exactly where to cut the grooves. I cut the grooves with a Dremel tool but with patience could be done with small files. Slightly flare the opening to the grooves so the hood detents into the grooves when the are aligned. If you want to make it even better, you could slightly widen the ball bearing track (do not cut a groove!) at the four locations were the ball bearings sit when the hood is rotated to the proper "level" position on the camera. Then you have another detent where the hood is properly oriented on the lens. I wish these hoods came in versions specific for wide angle, normal, and telephoto lenses.

I have had these for over a year and I am happy to say that they have survived more than 20 times in the washing machine (i forgot them in there), many falls and stuff. They work just as great as they did in the beginning, would recommend to everyone and they are also very cheap!

these work great. works behind walls, ovens, stone walls and from inside washing machine. I was supprised on the reliability of this transceiver.

Thought i lost this little torch, 9 months later it falls out off my washing machine, got stuck behind the front rubber door Gasket, still has the original battery that came with and it turned right on, A little rust near the ring that's all the damage it suffered. I'm a fire inspector and use this a lot to read gauges and find hidden no no's in back rooms, this light rocks don't hesitate just get one!

I’ve had these for several months now. They’ve been through the washing machine a few times and still work and sound great for general purpose ear buds. I let my son borrow them the other day and he lost them. I was devastated. I’ve been looking for the same ones ever since. Well tonight he found them and gave them back and I am so thrilled. I never thought headphones would be a thing that makes my day better but c’est la vie.

Have had this gadget for a bit, I love it. I was sad when it went through the washing machine but guys it still works ?? Highly recommend

Lost this light at least 9 months ago, was pulling a load of towels out of the washing machine and this fell out........to my amazement the thing turned right on, original battery.....A little rusty put its definitely clean now, tough tough light.

Smooth bearings on the wheels and better sonstuction than the yellow/black carts.

Use for BxW negatives after washing

A very simple and affordable solution to print washing.
