Good afternoon! Here is the link for the hand-held press discussed at one of the meetings. I was using an arbor press to press PEM nuts into ring terminals for making bolted high current connections, but the hand press is much easier to use. https://www.amazon.com/02612A-Various-Leather-Compound-Leverage/dp/B0002T87CW

The ring terminals need to be thicker than 0.060" or 1.5mm to ensure the steel of the PEM nut does not become the current path (the PEM is recessed in the tinned copper ring terminal). https://www.pemnet.com/wp-content/uploads/sites/2/2022/06/Fastener-Performance-in-Copper_5_22_20.pdf I have used the M5 PEM nuts and 1/4" ring terminals listed below. https://www.mcmaster.com/95117A442/ https://www.digikey.com/en/products/detail/te-connectivity-amp-connectors/31811/299307 Happy to answer any questions. I plan to attend today's meeting. Thanks, Shane -- 919-348-0061 cell Electrical Engineer | Consultant FRC Robotics - Control System Advisor www.linkedin.com/in/shanetrent
