derim 22LR and sizing brass with pneumatic press!

[Spanners]

Nearly there, your idea is defeatable by holding / jamming your safety button down!
The real way is to have to actuate both buttons within a short time...


Anyroad I've said my piece, carry on guys!!!!

Deffinatly - I do the same when playing with my hydropress, however you can only do your best to design a safe item - when people mess with it can you really be held responsable?
people will always try to get aorund things - can only do your best so that when used as designed here is no issues

[Hammer]

BT - You have done it again! Great idea. BUT!

Having to go back and ADD safety after the accident won't help your business liability insurance rates one lick!

Glad to see you chasing the 22 LR to .223 market. Welcome Aboard.

Thanks guys,

At the moment this machine is nothing more then a personal item that I chose to share a short video on. Yes I have already discused with the designer how safty buttons and measures would have to be taken if somthing like this was ever to be offered to the public. At this time it is not avialble yet.

Yes having to go back and add safty would be a bad thing in case of an accident. Just to clarify, there has been NO accident as it could be read in "the accident".

Good shooting and I'll keep it safe.

Thanks

A second less powerful pneumatic piston could move a feed bar back, similar to the annealer I posted.

You could also use a motor, and do something similar to the Magma bullet sizing machine, with auto feed:

YEars ago, I was the New England sale guy for a rivet making company out of Waupun, WI. They also made and sold riveting machines.

I sold a machine to a company in Concord, NH, and normally the machines would ONLY go out the door IF we installed a proper safety mechanism. The customer got to choose from three different methods.

This particular customer decided that they would install their own safety.

I still had an obligation to be on site for the start up run, and to do training.....

I arrived at the factory at the appointed hour, but was stunned to learn that the lady that was going to run that machine has already put a rivet through her hand. The company never installed the promised safety.

I hope that lady sued the crap out of her employer.

Google " two hand NO Tie Down air control system". Look for a set up that requires button push at the same time and that has the button facing 180deg apart so that they can not be bridged with a pusher bar.

Very Cool looking gadget BT.

If it can happen it will happen.

If one is going to sue for a accident caused by a hydrualic press can I sue the reloading die makers when I jab the decapping pin in my finger.

Too many lawyers takes all the fun out of making anything.

OK Brian, I just could not let you have all the fun.

So I tried to make an air powered ram, like yours, for my RockChuck press.

I did not know what size cylinder you used, so I started with a cylinder with a 1.5 inch dia bore.
NO GOOD, not enough power.

I then found a 5 inch dia bore with a 4 inch stroke.
It has all the power I need, with 100 psi, to derim 22 LR brass.

I used a 4 way electric air valve with a hand held push button to operate it.
I put the brass on the punch with one hand and then push the button to activate.

It also moves a slower than the one you have, which is a good thing.

My press has the Dr Blackmon mod done to it, which has the swage dies on the ram, not in the top of the press.
The top of the press has a floating punch holder for the top punch.
This gives it a auto eject system on the ram down stroke.

As an extra feature, it will also squirt my 22 cal cores from my lead wire.
It will seat the cores in the jacket and put the point on the slug as well.

I made about 2 dozen 55 grain HP slugs tonight to test it. Works GREAT.

No, I WILL NOT make one for anyone else. Just mine.

Cool,

Glad you got it up and running. Be careful, it makes you lazy, next thing your going to want is a Hydrolic Swage Press

Good Shooting and Swage On

Guys how did you attached into the press.
It uses leverage or it is straight powered from the bottom?
Thanks for your answer.
One picture is more that thousands words

[DukeInFlorida]

Brian and I talked about this recently. It's nice that rasto asked about it.
What Brian didn't show in his video is the actual pneumatic cylinder, etc.

So, Brian... when you get a moment, would you get out your video camera again, and show us what the cylinder looks like, how you hooked it up, foot pedal, air consumption and psi ratings, etc, etc, etc.....

Would love to speed up the derimming process.

[rasto]

Duke you right as alfloyd stated previously the cylinder should be strong enough to withstand and provide necessary power.
To make things easier I am planning to place the cylinder beneath the Lee classic cast and simply attach it directly to the press valve.
No leverage, no special tools or components.
For this reason I decided for this cylinder
http://www.smcpneumatics.com/CDQ2B80-100D-F7PV.html
which should be able to provide pressure of 3170N/0.7MPa what should be far enough for just derimming
PS check ebay for half of price

You guys have it right about the two button safety. My dad had to go to Mexico to train the new employees that were now going to be taking over American jobs. He came to a machine that was already in use. It was a large press that stamped out plates. There was two guys on this press, each of them holding down a button. As you can imagine, my dad freaked out and explained to them need for ONE personae to operate the machine at a time. Nice to know in Mexico they have plenty of money for the labor. Two guys for less than the price of one.

After this incident, he quit the company. He didn't want anything to do with them anymore.

I have a box of pneumatic solenoids and a few cylinders laying around, I need to get to work...

[rasto]

It seems to me that we need to use our own design.
Solenoids are the way to go together with at least 50mm cylinder pumped by 0.7Bar.
Maybe some speed regulator would be nice to have on the way to cylinder

[jonblack]

Like someone else said, just use an optical switch, like a garage door opener. There is a video on YouTube of a can crusher with optical safety.

Sorry to drudge up an old thread but I was curious if alfloyd or anyone else who has made a pneumatic setup for their press.. Derimming manually sucks! And my back sure as hell doesn't like it... Thanks.

[BT Sniper]

I have the necessary components in the works. The support arms necessary for the Lee Classic cast press are ready. I am sending the new rams for the press in to be nitride processed.

I plan to offer the components in a kit form. Haven't done so yet simply because I'm simply trying to catch up on current orders first. I'll have pics, plans and supplies ready very soon. Entire press can be put together for very reasonable price.

You guys will need to provide a bit of the pneumatic knowledge required to complete the simple build as all I plan to provide is some of the basic structures required for the build. This keeps BTSniper llc. out of any liability issues should anyone ever punch a finger or blow up a press.

[USMCamp0811]

Awesome my back much appreciates that news!

[BT Sniper]

Oh... Believe me I understand! Two things I can't live without when it comes to swaging....... an auto eject system of some sort and a form of power for deriming brass.
