Compatibility issues between gimbal and center post despite both being rated 1.5 inch
12 years old. Gear and prices may have changed since.
What the thread found
- Different manufacturers use different tolerance specifications for supposedly identical 1.5 inch components, causing fit problems when mixing brands
- Manufacturing tolerances of only a few thousandths of an inch can create the difference between a loose and a tight fit at this diameter
- Two separate 1.5 inch standards exist: one for PRO equipment and one for CP equipment, with the PRO post being approximately 6 thousandths of an inch larger
- Gimbals and posts from different brands may have tolerances at opposite extremes, preventing assembly even though both components meet their respective specifications
Depends on
- The discussion involves specific equipment models from 2014 and may not reflect current manufacturing practices
- No measurement data or testing methodology was provided to verify the tolerance claims
