Mystery solved. The app I was using is off by about 20 degrees in the range I'm trying to measure. I compared it with a speed square and protractor tonight. I should have checked it sooner. technology... Shoutout to the guys from Batson that were nice enough to provide a reference measurement for a rainshadow popping blank I had. Thanks to everyone who commented.

Thanks for the reply and the data. I'll try the tip extension angle indicator soon. I have the chart printed out. I'm just trying to prioritize my troubleshooting. I'm not advocating for sloppy work and saying it's OK to ignore the recommended method. The whole point for me is to get my process aligned with others -- so thanks for your input!

Thanks for the replies guys. I guess I missed the 10% offset for the handle. I took a few minutes after work today and measured a rod built on a rodgeeks B470MF blank. It's a 7' fast-tip st-croix medium blank. I'm re-reading some of the docs now and I think I identified something I'm doing wrong. I'm leveling the rod by aligning the mid and tip sections on my horizontal "0" line. The below link suggests leveling it nearest the handle and ignoring "tip droop". It's possible I'm tilting it up in a way that requires more mass to reach the 1/3 critical displacement point. https://www.common-cents.info/CCS_basic_Layout_1.pdf I want to try again tomorrow but I'll share my results anyway for anyone interested. I have the mudhole CRB blank mount tool on my wall ( https://mudhole.com/products/crb-deflection-tool ). As best I could I made the front support 10% from the butt end --> 84 * 0.1 = 8.4" ~ 8 & 3/8" 84" / 3 = 28" Mass needed to displace tip to 28" = 530g Angle with tip displaced 28" = 83 degrees I'm not using the tiny rod taped to the tip section to help determine the angle. I'm doing it visually on the first 3 or 4 inches of the rod. My method has already gotten me into the 84-85 degree range on rods I would describe as moderate. Extending a tangent line from the very tip would give the steepest angle so I think that is not the issue. I think it's a setup or initial measurement issue. Using the "Angle Level" app is tricky and annoying for now but it's accurate enough I think. Below are rods I have available to compare. If you know of accurate CCS data on these please let me know so I can use it to dial in my setup: Loomis GL3 SJR783 6'6" MH F Loomis GL3 SJR782 6'6" M F Falcon Cara Reaction heavy cover jig (would really like to clone this blank) 7'4" H 1/2-1 oz Falcon Cara Mansfield 7' M 1/4 - 5/8oz Falcon Cara Finesse Jig 6'10" MH+ F Falcon LowRider Carolina Lizard Dragger II 7' H Falcon Bucoo Trapcaster 1/4 -3/4 MH (good casting... wish it was available with better components) RodGeeks B470MF 7' M RodGeeks B470MHF 7' MH Liberty Flipping FP764 Rainshadow RX6 844 popping blank St Croix mojo "topwater" rod 6'8" or 6'9", 'medium' XF Thanks Again

Hi guys. Hobbiest rod builder here. I'm getting deeper and deeper into the game on each build. I want to characterize some off-the-shelf rods and compare to new blanks. As long as I'm doing all the measuring I'm all good, but I would like to be able to compare to other folks' measurements as well. I was getting IP in the 500g to 800g range, which seems OK, but my action angle readings were all quite high -- all within 84 to 89 degrees for a variety of blanks. I expected it to be lower and with a broader range. My method: Measure total rod length. Divide by 3 to determine deflection point for used for IP. For instance old GL3 G Loomis SJR783 is 6'6" = 78". 78/3 = 26". With the rod horizontal I mark a reference horizontal line on my wall. 26" below this I mark another horizontal line. Using a paper clip and a paper coffee cup to hold the weight I add weight until the tip of the rod reaches the lower 26" line. Using an angle finder app on my phone I align one straight edge of my phone with the first few inches of the blank nearest the tip. The rod tip is ~1" away from the wall at this point. My phone is flat on the wall behind the blank. I sight it in the best I can and capture the measurement. Once I record the angle I carry the weight used to deflect the tip to a scale and measure in grams. The SJR783 6'6" MH spinning took 575g to deflect to 26" below starting point. The tip angle when deflected 26" below the starting point was 84 degrees. Does this make sense? For my length measurements I used the total length of the rod ignoring grip length differences and reel seat position. Is this the preferred way? If I was going to measure a bare blank I would measure the whole thing, right? I'll keep looking online for other reference measurements and descriptions of processes but most of search results return fly rod stuff or ancient threads arguing how it does or does not appropriately assign a power and action to a rod. I'm interested in making simple and repeatable IP and AA measurements in a way that is compatible with others for comparison purposes. Thanks for reading! Please let me know what you think. Tight lines, Screamin' drags and full livewells friends!
