Hey Jim, until now, Onefinity never called the Y axes “Y-35” or “Y-50”, but it’s me who does that because it is logical 🙂 | Model | X axis | | Y axis | | --- | --- | --- | --- | | Machinist | 16" **X-35** | × | 16" **Y-35** | | Woodworker | 32" **X-35** | × | 32" **Y-35** | | Woodworker X-50 | 32" **X-50** | × | 32" **Y-35** | | Journeyman | 48" **X-50** | × | 32" **Y-35** | | Foreman | 48" **X-50** | × | 48" **Y-50** | > [@Differences Between X-50 Rails (upgrade) and X-35 Rails (standard)](https://forum.onefinitycnc.com/t/differences-between-x-50-rails-upgrade-and-x-35-rails-standard/6033/1): > > ![Machinist vs X-50 End View Stock Photo](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/a/6/a6d9520a4eb4011bcdd5285956e8c459ed87c389.jpeg) Left: Rail with 50 mm ø chrome-plated steel hollow shafts Right: Rail with 35 mm ø chrome-plated steel hollow shafts The photo was obviously made when there was a “[Woodworker](https://www.onefinitycnc.com/product-page/build-your-own-onefinity)” and a “[Woodworker X-50](https://www.onefinitycnc.com/product-page/onefinity-woodworker-1)” version, but it shows the two sizes of Onefinity modular rails system. #### See also - [Will there be "Y-50" rails on Y-Axes soon too?
