Rotex 150 - suggested wood sanding steps
« on: October 25, 2018, 12:02 PM »
Hello all.  I have owned my Rotex 150 for about a year and a half now I think and really like it.  I was introduced to it by a guy that does a lot of slab tables (mostly walnut and maple, but others).  His method of sanding was to start at 60 or 80 grit depending on the roughness of the slab, use Rotex mode all the way up to 220.  Then he would switch to a Makita 5" ROS and start all over from 80-220.  He said the 5mm stroke of the Rotex in ROS mode produced too noticeable of a pattern.  He typically finishes with a satin conversion varnish. To me, this seems like a lot of wasted steps with the ROS, but that's how he rolled and the finish was fine.  However, I am wondering what most Rotex users do in similar situations.  I have watched a lot of videos to see what others are doing, read many posts, but see a huge variance in what people actually do.  I also watched the "Larry Smith" video that never used the ROS mode at all but went up to a polish surface using the Surfax products.  So, am a bit confused what a good sanding process is, blending both the geared and ROS modes.

Also, I have been contemplating getting a dedicated finish sander, like the ETS 150/3, but am not yet convinced I really need it for my projects which are typically wood tables with either a waterborne acrylic or poly.  Seems the Rotex can do it all, albeit with perhaps less finesse than a dedicated ROS.

As you've already discovred you'll get info all over the map on this question.
@ChiknNutz

I work with slabs all the time and here's my method. I'll use geared rotary mode starting at either 60 or 80 depending on the slab. Then progress through the grits to 150. 100 - 120 - 150. Then I'll switch to an ETS150/3 and repeat the 150 then 180 - 220 and usually 320.

You need to be careful in your technique in rotary mode and be sure to keep the pad flat on the surface.


Works for me.

You WILL get different opinions.

Than you for your input.  Your method essentially matches what I have adopted, though I stop at 220.  I see you are using an ETS150 as opposed to the RO150 in ROS mode.  I am curious as to what drove you to go that route.

In my case I own the RO125 which has a 3.6mm orbit and a ETS EC 125/3 which has a 3mm orbit. So when I switch from geared mode to ROS mode the difference in the orbit from my RO to my ETS it doesn’t matter much so I use the ETS EC because it is lighter and easier to handle but the results are virtually identical. For me you really have to pay attention to the orbit. That is where it is at. I also have a DTS with a 2mm orbit so I can go back over the surface with 220 and it might be even more effective than going up to 320 with the 3mm sander.
