Rotation detection update

Thanks for all the great ideas!



One very key bit of information I should have included in my first post is that the DC gearmotor doesn't have to drive the load directly. I can run the load with a timing belt. Now I can put a spring loaded belt tensioner against the belt. I can make the spring adjustable and put a limit switch against the swing arm. If the mechanism jams, the belt tightens and moves the tensioner against the switch and kills the power. Now I don't need a torque limiter.


T'was a troll after all, eh? Aren't you the clever bodger!

Notice all the good ideas people sent? Seeds to nurture and grow. What do you mean by "a troll"? And, I'm certainly not clever, that's why I have to do simple things.

I'm going to fully automate a Dillon 650 reloading press. All of my engineers and mechanics shoot so, if I draw up some designs, they will improve and build. But, they have to be seeded or a project like this would have at least 4 computers, 20 gpm of hydraulics, 10 hp of 3-phase motors, exotic alloys, machine vision and $20k of funds if I let them. Then, they would never finish it.

I have an idea for a bullet feeder, I don't like the offerings on the market. Much simpler than a brush machine's subsystems. I'm sure there will be other hurdles. My initial target is 2-3k rounds/hr., 6 months and $1k plus the Dillon. One of the guy's son is a cop and the rangemaster for his little city. He is starting to save brass that they used to throw away. (GAKK!!!)

New business name. "Ohio Brush and Bullet" Has a nice ring to it.

80%+ of my sales today are in products we didn't make 10 years ago in a market (food service) we didn't even have a toe-hold in. Before that, it was all industrial and hardware markets. Nothing is a stretch.

The loading is just a fun hobby for now...How many cases of ammo can I put you down for?

Well, that's just it: you have to be clever to do simple. Complicated is easy, simple is hard.

ROTFLMAO!!! and CITKB!

Good one Karl!!

Coke In The Key Board?

When folks post questions but omit key bits of information and then later reveal that they've discovered a solution far more clever than any offered .... I sometimes wonder if it might be a troll. Perhaps that's mean of me. If so, , shame on me.

Sounds like a neat project. Pls keep us posted.

Will you be posting a video when you get this marvel working? Please?

I just saw this today and the thread might be dead. I hadn't finished visualizing the mechanism, I originally figured on direct drive until I realized it didn't have to be. Again, not clever...lazy!

I know that song well. Ideas, inspirations and inventions arrive when they're damned well ready. I thought I had an idea for a tool today, was so confident that I even zinc plated it before trying it. I now have a nice bit of decently-machined zinc-plated chromated scrap. Oh darn! Abandon that concept so another can find its way out of the subconscious or wherever they come from.
