Using an AMP Mate to automate a Giraud Trimmer (updated videos)

[F Class John]

I was feeling creative and bored these past couple days so I started working on a new project I’ve had on the back burner.

 

[Hoser]

Friggin cool.

 

[Shooter13]

Looks good!

 

[Chasin Beaver]

Cool. I wouldn’t even know how to start building something like that. How do you keep case from rotating while being trimmed?

 

[J F Johannes]

Wow! Way cool! Nice work!

Yeah they didn’t know it could be done either so they were pretty excited to see an alternative use for their machine.

I was able to modify it to have extra weight to hold it in place but I’ve been working with the AMP guys directly and we might test a second kind of head assembly once the software and such is totally sorted out that will ensure pressure to the brass. It should be pretty awesome when we’re done with it.

Love the stamped stainless steel support for the AmpMate, reminds me....of ME!

John, you definitely think outside the box. Very cool.

Thank you

I love your innovation. I have great respect for those who can juggle all of those design balls and not come up w a Rube Goldberg type of gizzie.
Having worked w several engineers to make their ideas come to pass, my hat is off.

I appreciate that. I still have my fair share of Goldbergs too...

Kudos John that is awesome and and a great use for the AMP Mate - fix the case dwell time in the cutter and then you can change my "used once on the amp" ampmate to the giraudmate or AMPtrim

John,
That is very cool and nicely done. That is the type of things I enjoyed doing with I had my shop. Looking forward to having the shop again real soon.
Again, great work.

For the WIN!

I love your cleverness and creativity, not to mention your mechanical skills, great idea!

The one thing I'm curious about is whether the trim/chamfer will be one-sided without any rotation of the case? My Giraud will not generate a uniform trim/chamfer all the way around the case mouth unless I spin the case with my fingers a couple times. I could probably improve the trim/chamfer by setting the cutter blade a little better than it currently is, but spinning the case seems to be a big part of getting a uniform result.

Thank you for the kind words. Yes I totally agree about rotating the case when using the machine as do a number of other people that I shoot with who use one. Obviously at this time it does not have any kind of rotation however that is definitely something I am trying to incorporate as I move forward. That piece is a little trickier of course. I have actually been playing with allowing it to naturally rotate a certain amount while being trimmed by adjusting the amount of down force that is applied. I have found that has actually been helping. I should have some new software to test out later today which may yield even better results and I will keep everybody posted.

Wow, Just freaking, Wow...

got to love American ingenuity

Umm, where does the AMP come from?

Couldn't resist
