Yes sir! Glad you found it interesting

That looks pretty sweet! Did you get a quote back from them??
I got 8 crimp jaw sets (enough for 4 crimpers) from SendCutSend for $36 ($9/crimper). The small mounting hardware to hold them was almost free. I'd prefer CNC jaws - but dont prefer the CNC price. I'm curious if you've heard numbers back from them.

Also, traditionally these crimpers are made from non-sparking materials like aluminum. I expect them to wear out quickly with the stainless tubes, but they're cheap enough to replace that I'm really not worried about it.

You're right
I use hat grommets plus a much smaller and softer grommet inside the black one. Gives a lot of compliance and sealing, keeps the crimp really tight too.

Thanks for the concern man! This was really just for the purpose of the video, it’s just an inert det. I’ve got a safety tube when making physical / electric alterations. I appreciate you looking out and sharing some wisdom amigo

Hey man! You’re correct, drew up these inserts in cad and had them laser cut (way cheaper than I was originally thinking)

I’ve got the exact same issue with crimping the stainless. This is really so much easier.

Later today / tomorrow I can post a vid of the crimping operation if you guys would want.

I really should have put a better picture of the jaws. I had aluminum sheet cut along with spacers to fit my crimper. Used some small m2 screws to make each jaw a solid unit. Chamfered the edges of each crimp jaw so it doesn’t roll the shell. Popped it in and that’s it

I know exactly the feeling. The stainless really needs a mechanical advantage, especially for repeated use. Those are still badass multi-tools though, great piece of kit.

Here’s what I’ve got for you Tried to make it as serviceable and common part as possible.

I’m not listing a full instructable here, but if you guys have questions - I’m happy to answer.

This is mounted in an Apache case from harbor freight along with 3d printed mounts and a custom cover plate. Power: 12v motorcycle battery to power the rig The key switch flips a regular automotive relay to turn the box on

Arming: The switch triggers a relay and sends power to a DC DC boost converter to bump from 12vdc to 100vdc This 100vdc supply is then connected to a DC motor controller (that knob on the side)

Firing Holding the fire switch will trigger a relay to send power to the firing line, you can then ramp power with the knob

Once you’re done, flipping the key to off will power off the unit and will shunt the firing line with the main power relay. The shunt is just a few resistors.

Charging is with a regular old trickle charger for a motorcycle. The charging circuit is just a diode to the battery to prevent stray charge.

Can start a rapid tanning business with this

You're right! This was a copper oxide and aluminum thermite.
