I admit that I was a little confused at the beginning, for about 30 seconds and difficulties had to use the first disk on the mandrel.
Until I the "rotation" had: simply clamp the thick upper part of the spike between your thumb and forefinger and pull it downwards, insert disc, slightly turning and release Dorn-uppers. That's it! It takes less than 2 seconds with no exercise, no kidding!
Since man has only 2 hands, the often limited if, the mandrel is first firmly clamped in the machine as described in the statement.
Otherwise it is a gag for Mr. Bean!
Buying SpeedClic mandrels for 70 euro ... I can knock minutes on my thighs and gasping for air ... I'm sorry!
This is as if one buys a car, does not find the reverse gear and buys every time a new when he must get out of the parking space!
Granted, Dremel, the system can pay well, but a rip-off ...?
Albert Einstein once said:
"Two things are infinite ... the universe and human stupidity ... and I'm not entirely sure about the universe!"
Who is to speak yet again?
