Vibration Damping on Old Percussion Drill
Vibration Damping on Old Percussion Drill
(OP)
Hello there,
I have an old hydraulic percussion drill that I use to drill 25mm holes into rock.
Due to the percussive nature of the drill, there are extreme vibrational forces at the handle (in all directions).
I would like to retrofit the handle with some sort of damping without losing the capability of applying a force to advance the drill forward.
I have thought of using some spring damping, however I may prefer using rubber or a plastic to provide damping and transmit the force.
Do you have any suggestions for me to do this? I have access to a fully equipped machine shop.

Mike is on the right track, a bag of cement on the handle will perform wonders.

The forward and backwards motion of the drill is occurring at about 196m/s2!

Im assuming you are drilling vertical holes. If you are drilling horizontally, check out air legs

Frequencies range 1000 to 2000 cycles per minute.

Thanks, yes I am looking at a spring mount for the handle. I just need to work out how to design the spring correctly..
