Training device

[Chris Nagel]

Hey John, you're in the right place. This is the training section of the board.

By the way, we had a related thread that you might be interested in. You can read it here: http://www.saddoboxing.com/boxingfor...ternative.html

I think that a machine that can punch straight out is a good idea. Having a thick pad behind the punching machine would be helpful, since it's natural to throw a counter punch after slipping a punch.

Chris, I read that thread and it is nice to know people share my thoughts. It would be nice to have realistic punches come at you. I tried this in a few other forums and it was about 50/50, some liked it and others thought it was a waste. It IS a waste in thinking it can do all that a sparring partner could do. To me, they missed the point but we all have our opinions.

So I gather it is ok to post the device and it could be looked at here:

Ignore my poor presentation, take it for what it is rather than what it's not, and let me know what you think.

It was extremely hard to find the right parts to mimic human jab speeds and yet not hurt like a human punch does.

Hi John, sorry that your post didn't show up at first. Our forum is set up so any posts by a new member that contains a website link is blocked until a moderator approves it. It's just a safeguard against spam. Again sorry for any inconvenience.

Here are my thoughts:
That's really nifty! Very dynamic, especially with the feedback. I'd like to put a kiddy boxing glove at the end of it and tape it so that it's rolled into a fist.

I think it would be nice if you could get closer to it without the compressor and punching bag getting in the way. That way I can step forward after avoiding it's punch, or I can just bend a little at my waist so that my head is moved off to the side, and out of the way of the punch.

Anyways it's getting late over here (EST), and like to talk about this more tomorrow. Thanks for sharing!

Chris, thanks for the feed back and I appreciate this forum letting post what I have so it could be made better.

Real quick, I can not add gloves as it is now because of the weight it adds. I may be able to do a fake glove sometime that is filled with a light foam but that will disfigure in shape in no time at all. At least with the size fist it has now, if you can stop it slipping into you, you sure can stop a glove.

About the compressor and bag in front, that is just a traveling version I made to possibly show at some gyms. In reality, you can just attach the arms or arm to a wall, put them at any height, width or angle and have nothing else in your way.

About getting closer, I have data what your reaction time must be at the end of the 18 inch punch from slow to fast speed. When a person is let's say at 9 inches from the fist, your reaction time is about half because I had tested with radar the speeds at half way and they are just as fast as all the way. What I'm saying is, you have to be VERY fast at 18 inches let alone at 9.

[Chris Nagel]

Yeah that can punch really fast. Do you simply adjust the air pressure to change the speed?

[atgatt]

Yes, simply change to pressure to change the speed. Once done, the speed is very consistent. So let's say you got it down to slip a 7 mph punch, if you turn it up about 10 psi it will be a bit faster so then you work at that speed and so on.

The amount of punches and the sequence can be changed by the program setting. It could have numerous program settings. I'm only showing one.

An error people make is they say that they and others can punch much faster than 13 mph. So can I. My jab is 10 mph without cocking it first. My right cross is 17 mph and if I measure my long hook, it would be even faster. That only matters for power of the punch, not reaction times because those punches start from way back, and for a punch to start way back means some punch was thrown already to set up the long punch or the person moved a guard hand back to throw a punch from farther back. All of that takes time. So in reality, the true test of reaction time is WHERE the punch originated from the guard position and the distance it traveled. So a 13 mph jab (which may not be humanly possible) traveling 18 inches gives a reaction time of just 800 ms. If a person can stop that punch, they should be able to stop any of the others. I just don't think anyone is that fast but maybe some day a pro boxer will let me see if they can on the RBT. I'd bet they can't. Anyway, you get the picture.

Like the idea, but how was it tested, to do what it says it does. It doesnt add up.
