Automated my Freechex III

[altheating]

I finally finished my automated arbor press for making gas checks with a Freechex III. Works like a charm. YouTube video coming as soon as it uploads.

Great work! Now send the plans to China so we all can have one.

Very clever. But first impression was, "what on earth" this is unbelievable.

Cool!!!

I keep seeing a broken hand when the rocker comes down.

I watched the video.
I think I'll stay with the manual arbor press system.
That plastic cam looks to me like a " hand wrecker ".

Nice job, it continues to amaze me what members here accomplish. Thanks.

Its far enough away that my hand doesn't hit it. You can stop the cam by hand. The shaft that goes into the cam is actually slip fit so it will spin free instead of binding up the motor or damaging anything. I will eventually make a linkage system to run the ram when my son designs it for me on the computer. If I were to do it over I would have mounted the motor 2" back farther which would have moved the cam back farther. It works as is, I did over 7000 checks this afternoon.

Tie that handle down with a bungie to prevent all that slamming. Otherwise I think it rocks.

Thats tomorrow's project. I have some medical tube I'm going to try. Great minds think alike.

I'd like to have a foot pedal activating it. There is a reason machines have guards and redundant safeties built into them. The ingenuity is great. But not having any control of the motion is a way to get hurt.

All machines start without safeties. Its hard to add a safety feature without testing the mechanics. I'm sure he'll get there.

Maybe I see things from a different mechanical point of view. Having the motor operate only after some sort of user activation would have been my first thought. I had my hand pinched between a pulley and belt once. Not something I wish to repeat.

It is that difference that we all share here that actually makes this place worth frequenting. Not saying you're wrong, rather I'll assume he's contemplating his own safety.
Thanks for sharing about the belt. I realize that kind of thing happens, I build fully automated systems for a living. We almost always add safeties after realizing the risks involved in operation. Some are designed in, but most come after some use. Its kind of the carriage before the horse.
I'm also willing to bet the op was just so excited to see this working that he was ready to post and share.

I'm looking for a sewing machine foot pedal that will be rewired for a on/off switch.

[altheating]

Excited, yea, I punched out 1000 checks before I realized it was working.

[JeffinNZ]

Gold. Absolute gold.

And still some folk want to cut a disc and form it in a separate operation. They don't know what they're missing.

[Bored1]

That is nice! A sewing machine pedal would work great I would think!

[altheating]

Today I put the guard in front of the cam and added the rubber band to stop the slamming of the handle. Works even better without the slamming going on. Had to make a notch on the end of the handle to keep the rubber band in place. With the guard in place I can keep OSHA away. Now my hand can't get near the cam either. All is good. Still need the sewing machine foot pedal.
Anyone have a old sewing machine foot pedal they want to dispose of?

Got a link to the motor you used? Post up some pictures of the guard too if you would be so kind.
