Wire Rope Eye Splice

Theses 1/8" wire rope eye splices were rejected by JMP. 

Can you tell us why?

#1  No Thimble.  Though not required in all situations, it is JMP's practice to always use a thimble with wire rope eye splices.  We also only use copper sleeves with galvanized cable.

#2  Incorrect Crimping-  In addition to not having a thimble, this eye has only two crimps on the sleeve.  Our hand crimping tool for 1/8" wire rope requires 3 crimps on the oval sleeve. 

#3 Two sleeves and both are improperly crimped. 

#4 Crimping does not pass the gauge inspection.  Always check your crimps with a "Go Gauge."

#5 No visible tail.  Always leave a small tail exposed past the end of the crimped sleeve.  If you cannot see the tail then you can't be confident that crimps are properly placed over both legs of the wire.

Tips for correctly crimping wire rope:

Only use the best quality crimping tool and follow the manufacturers instructions.  For field use, we use a Nicropress 64-CGMP hand press.

Make certain you use the correct sleeves and stops with your wire rope.  Use only the sleeves that are specified by your tool.

Follow the instructions for number or crimps with the specified notch on your tool.  For our 64-CGMP tool, and 1/8" galvanized wire rope, Nicropress specifies:


Crimp order is important.-  When using a thimble in an eye splice, Nicopress recommends placing the first crimp on the end of the sleeve closest to the thimble.  In our 1/8" eye splice example, the second crimp is in the middle and the third crimp at the end away from the eye.   Nicopress always advises: never crimp between two previous crimps.

When in doubt, ask.  Consult with a certified rigger or call your tool's manufacturer. 

Holiday Greeting

This holiday season, all of us here at John Murray Productions wanted to send out a specially crafted holiday card to some of our closest contacts. In the spirit of our stagecraft background, we meticulously designed a wooden, build-your-own Fresnel ornament. Each package contains a sheet of balsa plywood with 22 snap out pieces routed on our CNC machine, an emery board for sanding, and a holiday greeting card that includes a link to a corresponding assembly video. We hope to provide a fun holiday craft along with some insight into how each project is completed here at JMP.

Happy Holidays from everyone here at John Murray Productions. Thank you for a wonderful year, and cheers to 2017!

Send us a photo of your ornament on display and we will post it here!

John Murray Productions provides last-minute field goal net for “the most important game of the season”

With a national broadcast television audience of over 16 million viewers, and college football playoff implications hanging in the balance, Safelight Auto Glass, a sponsor of Ohio State football, requested more visibility for their field goal net for the 113th showdown between the #2 Ohio State Buckeyes and #3 Michigan Wolverines, and John Murray Productions was brought in to provide a solution.

Undaunted by a short production window, we guaranteed a delivery on the Wednesday before Thanksgiving, for the 60’ x 40’ field goal net we received in our studio less than a week before.  The “X’s and O’s” were draw on the chalkboard, and our in-house printing and sewing team executed the play flawlessly providing the ‘go ahead score’.  But, it was our years of experience in critical, ‘game time situations’ that prevented a ‘blocked kick’ when we discovered that, for some reason, our shipment was refused at the stadium Wednesday morning (could this have been the work of a Michigan alum who secretly works at OSU stadium receiving dock?).  Making all the necessary calls, and stressing the importance of the game (for those who somehow didn’t know this was THE GAME), we had the delivery rerouted back to the stadium in less than an hour.  For Safelite Auto Glass, the fans in attendance, and those watching around the world, the ‘extra point’ was up, and good!
