looking4reloadingdeals Posted January 13, 2020 Share Posted January 13, 2020 Hello everyone, I’m looking at a Giraud trimmer and I’d like to set it up in a dedicated motor instead of using a drill. I don’t want to pay for the motor set up they have for sale on their site since it’s $300 more than just the trimmer, I would like to put something together myself. Has anyone come up a solution for this? I was contemplating a small bench grinder or such, but those spin at about the max speed recommend for the trimmer. Any help would be appreciated guys.

lonestardiver Posted January 13, 2020 Share Posted January 13, 2020 Use a pulley/belt drive from the bench grinder to reduce final RPM.Or use a variac to control motor speed. Link to comment Share on other sites More sharing options...

Maybe I’ll put some of the engineering classes to work and draw something up. The variac also sounds like a great option, thanks Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
clw42 Posted January 15, 2020 Share Posted January 15, 2020 I use the TriWay with a bench grinder at full speed. Has worked fine for three years and running. Many thousands of .223 cases trimmed. Link to comment Share on other sites More sharing options...

Did you need to take the threads off the grinder or did you just couple over them?Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk Yes, I think it's ~3450 RPM. It's an old Delta that my dad had. I used something similar to this. I think I got mine on ebay though. https://www.amazon.com/Climax-CC-050-037-Plating-Clamping-Coupling/dp/B005L69UPE/ref=sr_1_1?keywords=3%2F8%22+x+1%2F2%22+shaft+coupler&qid=1579126023&sr=8-1 Link to comment Share on other sites More sharing options...

I saw something similar on YouTube, but wasnt sure if running that close to manufactures max speed of 3500rpm was the best idea or not. Glad to hear it’s been working for you though, I might try one of the cheap $30 grinders for that and leave the other side available to use for a buffing wheel or something.

looking4reloadingdeals Posted January 16, 2020 Author Share Posted January 16, 2020 my Giraud Trimmer is the one reloading tool I will never be withoutWell I was thinking the other night while chamfering/deburring 1500 rounds of 223, there has to be a better way. Then I remembered the giraud, which I had seen a while ago but didn’t purchase because it was too expensive for me being a poor college student. Fast forward a couple years and I feel like I need one now, especially since I find myself wanting more uniform brass. Iv heard nothing but great things about them Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk It's been great. I turn it on, and then just run cases through it. Empty the shavings every few hundred rounds and run it again. My only advice is to insert the case slowly, if you jam a long one in there it will catch and spin in your hand...which makes for a bad time. On a completely off subject note, can anyone tell me why the link I posted wasn't clickable? Link to comment Share on other sites More sharing options...
