Yesterday we lost the second blade in the last 4 weeks. By the almost new condition of the paint and Carbide tips I assume it has been rented no more than 4 times.
The Pictures show 1 carbide tooth completely torn off; a second Tooth has lost two thirds of its support and has bent backwards. A third area of damage is on the backside of the blade.
Once a tooth is torn off the vibration takes its toll on the rest of the machine. Two of the 3 thumb screws that hold the Safety Cover had vibrated loose, and there was a complete failure of the outboard bearing support.
The picture without yellow paint was taken to show the almost new condition of the blade. The picture shows a small crack I missed in my first inspection. Further inspection revealed another crack.
Cost of this Failure is a Shaper Blade $200.00 Bearing Support $26.00 2 Thumb Screws $1.50 each and an hour of labor at $65.00. Total cost of repair $294.00
