NOTE: Measurement Procedure directions edited 6/29/24. Much more accurate technique. This Hand Gun Recoil Spring Weight Tester by TAM1 is a must-have for any gun enthusiast. With its heavy-duty steel and PVC construction, it allows for the measurement of recoil spring strength with a digital scale included. The set includes the scale, the threaded hook with a locked coupling, the threaded rod that holds spring and a PVC tube with steel reinforced cap. The tester assembles as follows: 1) spring is loaded onto threaded rod which has a spring stop washer threaded & locked on one end, 2) threaded end of rod is fed into open end of PVC tube and through end cap hole, 3) threaded eye hook coupling is connected to threaded rod extending out of PVC tube cap, the 2 easy steps for measurement are listed below. The process for measurement is easy to use and accurate and even includes a way to figure a standard deviation. The tester in the pictures is the one you will receive. Pistol recoil spring must be greater than 5/16″ and less than 1/2″ for 1/2″ PVC pipe or less than 3/4″ for 3/4″ PVC pipe. I have made 1/2″ & 3/4″ PVC models of spring weight testers. This recoil weight tester is perfect for guns such as the 1911 and semiautomatics. The range weight reading is given when the spring is fully compressed(directions to follow). The hand-made construction and reinforcement ensures durability and reliability. Please note that the scale is included with the tester. Scale tool made in the USA, this item is a great addition to any gunsmithing kit. If your gun springs get out of original packages or are installed on guns the spring strength is no longer available. This is what made me develop this tester. You will have a way to accurately measure their power weights. With this tool you can load the spring onto the rod and feed rod through PVC tube, then attach the eye hook with coupling onto the threaded rod. First pull rod until it stops. That’s full spring compression,. Mark rod with sharpie at hole on PVC pipe cap. Then attach the eye hook onto a digital scale loop. Attach the scale metal handle to a heavy fixed post or hook or just hold both tube & scale and pull until spring is completely compressed-that was the mark you just made on the rod. When you see mark on rod at the hole on the PVC cap note scale reading. It’s important to understand that the point to read the scale is when the spring is justcompletely compressed at that mark on rod(you can feel the point when the spring just stops compressing). It hits the non-movement wall, that is, it hits a compression stop wall. It’s helpful to practice with a spring of known weight to see and feel what & where the compression wall feels like. If the weight is different consistently on a known spring testing for example a known 20lb spring test results say its 19lbs you now know the -1lb error bias(standard deviation)and you can adjust future readings.After measuring the know spring you can feel the range of where complete compression occurs. The way we know full compression on step 1 of measurement is pulling the rod &spring until the rod stops-that’s full compression and we mark rod where it comes out at cap on PVC tube. Without disassembing the unit 2)we hook scale onto eye hook turn scale on and pull rod until we see the mark we just made. Note scale reading at that mark. You can create a false high readings if you continue to pull past the springs’ complete compression past the mark on the rod. The rod will not pull past the mark but the weight on the scale continues to increase. It’s easy to feel the correct compression point because tester rod stops movement and you can feel the rod movement stop(like a stop wall). After you do a measurement make sure you clean the mark off of the rod. Rubbing alcohol works great. For example a 20lb spring that is older actually is a 19.5 lb spring. It’s important to know that quality springs will last 1000’s of rounds. 1911’s require spring tuning & a lower weight spring that is barely funtional will not last as long as a heavier consistently functional spring. That’s why wolf spring tuning kits have multiple strength recoil springs and a mainspring. You can save the 19.5lb from above and label it & actually get more life out of it in another gun. I went through my springs and wrote spring strengths on Quart Zip Lock Bags to organize spring inventory. It’s extremely frustrating when you don’t have a way to know spring strength weight and expensive and wasteful to have to buy new springs. Believe it or not the length of the spring does not affect the strength of the spring. You could test this by measuring the strength of a spring then cut it to a shorter length and test it again it will have same strength weight but the mark on the rod will be different. The overall engineered power of the spring is affected by its length. An example is the different length springs in 1911’s CS, MS & FS with functional power weights being engineered into each size springs. When you install a spring on gun label a note card with date and strength of spring & keep card with gun(in gun box/case)Good luck and have fun organizing your springs.
