Its like the frankford arsenal, but i have designed it "better", all 4 3 stations are with 2 ballbearings, and the trimmerhead doesnt wobbl and you cant move it to the side. i use more rpm (400 at trimmer and 220 at other stations) and more watts (80 vs 60 from the frankford). the frankford design is more universal, mine is more specific (angle of shoulder at the inserts). i build it with pwm control, so you can adjust the rpm.
