Random Orbital Sander behaviour question

lundi 28 juillet 2014

Hi,





Looking for some advice / explanation on ROS behaviour please.





I am using a Bosch GEX 125AC random orbital sander and at about 5 years old its seems to be holding up well,

except that it seems to have lost the plot for holding on to the sanding disks.

After shorter and shorter periods they just frizbee off across the workshop.

If I turn the speed down they hang on better but then I get swirl marks.





Seems the thinner 'for paint' discs behave better than the thick ones.





So does the velcro of the backing pad wear away over time?

Would you expect the back of the disks themselves to wear more than the sandpaper side

(I am getting a big pile of disks that feel like they have plent of cut left)





Should I be looking at replacing the backing pad or a whole new sander?

Heaven knows what a space for a five year old tool would cost anyway.





Thanks

JC
