RO150 question?

[Thompmd]

Been using this awhile and stumbled into something a couple projects ago and wondered if this is how I should have been doing all along?? For a long time I had mixed results for various reasons, some I figured out and some I was unsure of.

I tried using the lower grits I the Rotex mode and then just the standard RO and so far I’ve had good results ?? Is this how you typically use?

That is exactly my routine.

Thank You and happy new year

Depends. Often I use Rotex mode in higher grits to wipe out the prior course sanding marks quickly. Do clean the surface every time you change grits.

Thanks for the reply and I have a couple more questions.

I don’t clean the surface at lower grits, only the last one, maybe 2. That could be part of the past problems.

I also use the Rotex mode to clean up any sanding marks and this is often where problems occurred in the past(for various reasons).

I’ve only been doing this a couple years, I’ve learned a lot, but still along way to go!!

All my tools are Festool/Powermatic/Sawstop so I’ve bought the best tools I can afford(funny as 3-4yrs ago I’d never heard of Festool). My skills lack a lot and having good tools eliminates part of the equation IMO.

Generally speaking, I only use the RO-150 when I need to aggressive rotary action for stock removal and shaping. It's a two-handed tool and I prefer my 150/3 for any other sanding up through "finish".

Mine are the two smaller units (90 and 125) but same other than size. I used them both like Peter_C does. The orbital mode seems to work better in a polishing capacity, so the higher grits get close, even good enough in some cases. Other times the foam or felt pads, along with some liquid polish or compound, finish the job.
For regular sanding the (in between stuff) an RO would not be the first choice though. ETS EC125 would be the go to for normal hardwood, doors, faceframes, etc.

I start low on rotex and before I move to the next higher grit I switch to RO and hit it again with the current grit. Then back to Rotex with the next grit and switch to RO then on to the next finer grit. etc. Works great.

+1 Same here. The ETS 150 EC handles much easier, I use geared for paint removal mostly (GET 75-150, sorry, and RO90).
