I have been looking for a light weight controlable 5" sander. I have an ETS 125 but I've never been completely satisfied with it. So when I saw the Mirka Ceros 550-CV I had to have one. However, I did not like removing the end from one of my Festool 27mm vac hoses to thread it into the sander each time I use it. So I decided to set it up as follows:
I used a Systainer 4 instead of the systainer provided with the Ceros sander.
The sander, transformer and vac hose fit nicely in the systainer 4.
I even attached the lid display from the Mirka systainer in the systainer 4.
I installed industrial strength velcro to the transformer and the systainer lid to mount it while using the sander.
I now can get the sander and the hose out and attach them to the vac and the transformer. Notice I used velcro tie wraps to attache the power cord to the hose.
I converted the Mirka systainer that the sander came in to a sanding disc storage unit by ordering the 125mm insert trays from my Festool dealer, Dennis Kent with Woodcraft in Matthews, NC. I used two inserts so I could double up on the grits.
So far I am completely satisfied with the Mirka Ceros sander and have found this setup works great for me.
