I'm trying to build some antennas, and needed to straighten ( remove small bends) to get my measurements more accurate and reach resonance. This model is one of the only tools I could easily find online and it works so well! I still need to adjust the bearings for correct unbending but I am grateful to you for making this!I did not have 35mm screws so I just added a 3d printed washer on 40mm one. (edited)
