ROS keeps throwing disks - any ideas?

Interesting to read this thread and all the responses from it.
In our experience, it is normally the velcro on the back-up pad that is giving way, rather than the velour on the sanding discs being of poor quality.
The most economical way to rectify the problem is to buy a hook & loop converter/starter (available from our online store), which is a piece of velcro with an adhesive backing.
This enables you to extend the life of your back-up pad considerably if the rubber has not been too damaged.
It is best not to try and pull the old velour hook from the back-up pad, as this will only end up de-laminating the rubber. The best way is to sand the hook off, clean the surface, and then apply the above-mentioned hook & loop converter/starter.
These hook and loop starters are what you would put on a faceplate on the end of your lathe if you wanted to put velcro discs on there.
We also stock 300 mm wide hook & loop starter material, so that you can cut your own shapes for sanding blocks, delta sanders, etc. As yet the 300 mm wide material is not listed on our website, but send us an email if you are interested.
Hope this helps.

Inkjet can be one of the cheapest to run if you buy your own refill cartridges and refill it yourself. $7 gets you 3 refills for my printer and i've done it about 10 times so far with nothing wrong... turns a fortune to run into one of the cheapeest to run

Get it from coles/woolies

Hi I had a Makita ROS & it started flinging discs- it was getting on so I bought a new makita. First disc out of the box & it went flying !!!! I was 3 metres up a ladder at the time - not happy . I complained & Makita gave me a new velcro pad - same result .
I ended up buying a blue Bosch 150mm ROS [with turbo ] and the only trouble I have now is trying to get the discs off the velcro.

I went through the whole mucking about with cartridge refills in the early days and how they'd always dry up if not used for a long time once opened. I can tell you that a laser costs even less. Yes you can get (toner) refills for laser cartridges. Even in comparison to inkjet refils it much cheaper. Anyway beside the point as you can't get "refills" for discs :lol:

I like my simple sheet based sanders. Don't have any cut sheets? I just go into my stash of full sheet sandpaper and rip a fitting strip off, punch a few holes with the provided template for dust collection and I'm off. I will never ever go back to velcro based products ever again. I was never a fan of the rotational sanders to begin with, by that point you might as well go for a belt sander.

Hi,

I haven't been on the forums for a while but just noticed this thread.

I've had a Bosch ROS for years, and never had this problem until recently, unless the pad got really, really dusty. I use the blue pack pads from Big B too. It's been great, but sadly I'm about to give up on it and pads, as in the last 6-12 months I've bought 4 or 5 new pads, and pretty quickly they start throwing disks.

So i wonder if the pads are a different quality than they used to be? More susceptible to melting? Less catch on the hooks?

Paper seems OK as when it doesn't stick to the ROS I cut out a triangle to go on my detail sander, and it sticks fine until dead.

So a Sander which cost me around $100 has cost me equal to that in new pads, and twice what I'd plan for in paper as eiach piece only lasts a little while.

Be interested to see if anyone uncovers the answer....

Regards,
Darren

My experience is that not all hook material is compatable with all loop backed papers.
