JMP Celebrates 30 Years in Business

July 2019 marks 30 years in Business for John Murray Productions, and we celebrated this impressive milestone with an Open House event where clients, vendors, and fabrication partners joined us for some entertainment, a tour of the shop, a Modtruss demo, and a trip down memory lane. The celebration continued into the evening with a staff party where friends and family joined in on the fun. We had a blast and a big thank you to all who came out. Congratulations to John and Clinton for 30 years of success in the special events industry!

Take a look at the video below highlighting this journey that brought us here today and the team that makes us so great.

Take a peek at some of the event action below. The staff sure took a beating on the Modtruss slingshot!

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.
