<< you cut about 7 mm and then, the plastic sticks on the blade, goes jumping around, and breaks (even with speed at it's lowest setting). Once I could cut through the 22.5 mm width of the key, but then the 20 first mm were stuck together again. >> A little spray teflon or even the powder works well to keep the plastic from sticking. If the blade gets hot, that is where the trouble starts. Ed Foote RPT http://www.uk-piano.org/edfoote/index.html www.uk-piano.org/edfoote/well_tempered_piano.html
