Hacksaw cutting guide MGN9 rail

thingiverse

MGN9 rails are made of hardened steel, requiring 20 minutes to cut through with a junior hacksaw. Each 150mm junior hacksaw blade can only cut about 1mm depth before becoming blunt. Once a blade is dull, sawing for 24 hours will not yield further progress. It typically takes 2-3 minutes for the blade to become dull. To accomplish the task efficiently: Get a pack of 10 hacksaw blades costing approximately £2. Saw for just 3 minutes before switching to a new blade. A total of 6-7 blades will be needed. A 3D printed guide block helps align the blade when starting to cut, and protects the rail from scratches if the blade jumps out while cutting. Secure the guide block to the rail using M3 nuts and bolts. Leave a like if this information was helpful.
