RO 150
« on: October 07, 2021, 09:33 AM »
Does anyone have trouble with their RO 150 wanting to jump around you can’t hardly sand with it sometimes. I will be sanding just fine and all of a sudden it will start wanting to big jump all over the place. Gets annoying

I recently bought an RO125, the little brother of the RO150.  When I first used it (P40 Granat on a piece of scrap plywood) it was very difficult to control.  It's taken me some time and practice to get the hang of it.  Just keep using the machine on scrap material to get the hang of it.  I've found that using it at max speed with a firm grip with both hands works best.  There are still times when it wants to jump around, but I'm getting better at controlling it.

It's amazing how much material it can remove!

I recently purchased the RO90, because I read and saw that some woodworkers seem to prefer it for many tasks as it was easier to handle.. plus it had the delta pad. The 125 and 150 in rotex mode seem to be close to right angle grinders.

A bit off topic...I've been making some bookshelves and display boxes out of OSB.  The RO125 in Rotex mode with P40 paper makes light work of cleaning up the factory delivered surface of the OSB.  Switch it to random orbit with P120 and it smooths out the varnish between coats.  I'm using it with an old Dyson cyclone vacuum cleaner, it's amazing watching the dust bin fill up.

That's funny, most of the time you will hear people say exactly the opposite? The "haters" all say that the RO90 is the hardest one to use.

All of the Rotex sanders are very aggressive, especially with course paper, but when I need to get serious, out comes the RAS115.

I find so long as the vac is turned down to minimum (1 from 5 on the midi) then my RO150 is very easy to control.

If the vac is too high it can certainly grab and jump.

This almost always does the trick.  You can also turn the speed down.

I've used a grinder with sanding attachments and it is pretty difficult to control. So I knew I didn't want to go that big with the Rotex. We have two sets of stairs to sand so it will come in very handy.

I'm sure it will do you well. On stairs and other tight spaces, it really comes into it's own, and that's just the round bit. Once you swap in the delta pad, you can get it all.

The Rotex sanders have a long history of breaking in users to their quirks. If you have not found them already search YouTube for some videos on the subject of using a Rotex successfully. In my experience the keys are as follows:

1. Set the dust extractor to as low a setting as possible without leaving a mess. The lower the suction the better the sander will behave. 2. Let the sander do the work! Very little downward pressure, be patient. 3. Right hand on the hose or cord connection, just holding onto the tail of the beast making sure that the tail stays up so that the sander does not heel. Front hand in the very front, pretty much just steering. That long heavy sander wants to heel back but don’t let it. Keep the pad nice and flat on the work. 4. I put my right hand under the hose and then come back around to hold the back of the sander. This allows the hose to wrap around your arm and that helps keep that tail up. 5. If the sander still jumps around lower the sander speed and see if that helps. 6. Make yourself use the sander, you and the sander have to break each other in. 7. From time to time take the pad off of the sander and check it for warping. It is rare but it happens.

The RO sanders are a handful. But practice enough and using them becomes second nature.

The 150 is WAY easier than the 125. Almost a zero learning curve compared to the 125.

Make sure you have it in random orbit mode and not eccentric mode.

Had the RO 150 for a couple years now and have to say it's been great to use. bit of a beast, but that's what I wanted. at first you (I) need a little care in the geared mode with course discs as it only takes a little bite, or shift of pressure you let you know the power it has, but very quickly get used to it. like most tools, let it do the work and its a pleasure to use. With extraction on, you could be forgiven for not thinking its doing much, get complacent and occasionally caught out. without vac you realise how much these machines chew through. that said, I've used it to fine polishes on worktops and it's done it superbly and with total control.

  I agree, I still don't own the RO 125 because the RO 150 is easier for me ,to use in Rotex mode. I suppose if I owned a RO 125 I'd 'get' it eventually...

I find the suction is the biggest problem, it has become second nature to double-check it when I get some jerkiness in the 90 or 150. Usually, I forgot to turn it down to just under half.

I use two hands if there has been any significant time between uses but it only takes a couple of minutes to get used to them again and I am back to one handing either of them. I find orbital to be more of a handful than rotex probably because I spend a lot of time in Rotex so I am more used to it.

I also find the RO90 is significantly hard to learn and use than the RO150. The 90 was my first and when I got the 150 it was like going from riding a rigid tail Harley to a nice fully suspended cruiser.

I have though about putting a tag on the RO's on top that's says, set the vac!
