Festool RO150 E ----> CTL Midi: How to connect?

[ktz]

Hi all,

I have purchased an older RO150 E model sander and have noticed that the dust extractor doesn't seem to match up to the hose on my CTL midi dust extractor. The sander seems to have a kind of oval shaped hose connector whiles the CTL has the standard circular hose.

Is there an adapter I can make or purchase to make these work harmoniously? My RO150 looks like the attached.

Thanks in advance for any help!

Joel

First,  welcome to the FOG!  Regarding your hose / sander connection, squeeze it to form a smile and push it on.  It fits with some effort.

You'll be smiling soon yourself.  [big grin] [big grin] [big grin] [big grin] [big grin]

welcome to the  fog

unfortunitly the only option is to force the hose end on.
it will work perfectly but not be pritty.

Why not? It's a piece of cake to get it on.  ???

i dont think it is a good system. i think it damages the end of the hose end and makes it weaker , it then wont hold on the other tools as well
iv played with a few tools at demos and hated putting on the hose on an oval dc port.

Quite the contrary. The oval dust ports are used on some Festools because that is the shape which works best.

My experience is that the advantage to the oval dust ports is that the 27mm hose tool end holds onto the oval better than the round dust ports.

With some sanders the hose grips the round hole well enough. but the nature of the tasks done with the RO150 can involve rapid movement of that sander.

I bought a RO150 in early 2006. At that time I owned my first CT26 and used that 27mm AS hose with the sander. I still own both the sander and that 27mm hose. The tool end must have been attached to Festools over 1000 times without damage to the hose. Some of the ports are oval and some round.

A little practice is all it takes to be confident attaching and removing the hose from oval ports.

I think it's funny every time this topic comes up.  It's a rubber tool end so why wouldn't it fit an oval port.  After all, an oval is a flattened circle.  I don't mean this to come off as mean or insulting, it just strikes my a funny. [big grin]

BTW, welcome to the FOG Joel!  I think you're going to like around here.

Hi Joel,

I also have that same Rotex and use it with the 27mm hose. I have never had it come off the oval dust port whilst using the sander and it still fits fine on all my other tools that have a round dust port. I mainly use my Rotex for Solid Surface work so it is constantly on the go and it does grip the oval connector really well.

Welcome to the FOG by the way!

BTW, when i first got mine, I rang Festool UK in BSE to see if there was something missing as I had expected the tool to have a round outlet but they said that this was the way to connect the hose and that it would stay on the tool. They were right of course!!!!

Well—that is great news! (Here I thought I was going to have to purchase another out-of-budget accessory).

It all seems logical I guess (now I feel a little stupid for asking), just didn't want to risk damaging the hose and for some reason. Everything else I have ever used Festool-wise has seemed to be perfectly fit for purpose, so I figured this would be no different. I guess it isn't!

Thanks for all the replies and help. Looking forward to getting my sand on.

I don't think it damages the hose end. The rubber is flexible enough to compensate, I don't see a lasting effect. But I also think it performs less well as the round dust port, because with the tools I have at my availability (DX, RAS, RS 300, PS 200) the hose slips off all the time, while that's never a problem with tools with a round dust port. The hose slipping off is pretty annoying.

Quite the contrary. The oval dust ports are used on some Festools because that is the shape which works best.

My experience is that the advantage to the oval dust ports is that the 27mm hose tool end holds onto the oval better than the round dust ports.

As mentioned above, my experience is most certainly the opposite. And a bit of logic would tell you why. What is the saying? "Don't try to fit a square peg into a round hole". It applies. As illustrated below you get a nice conform fit when round goes over round, evenly distributing the friction. But when you want to fit round over oval you have to deform the hose end, messing up the friction distribution. At the sides the force becomes bigger, but in the middle it diminishes. The increased friction on the sides does not compensate for the loss of friction in the middle, making the overal bond less.

For a certain time Festool was very interested in the oval dust port, using it on many tools, but whenever a tool got a major update, they dropped it, and none of their new tools have it either. I guess they learned their lesson.

Thats a fair point you make Alex!

However, I can only base my opinion on personal experience and so far as the 27mm hose fitting successfully over the oval dust port on the older model Ro 150 is concerned, it works perfectly well for me.

I must admit, it is the only oval port tool that I have but the round hose end still fits all my other Festool tools and Dewalt/Elu routers with a round dust port without any adverse effects.

Yes, it does work. I'm not that bothered about it either. Just a minor annoyance.  When I'm working an entire day, about 5 times perhaps it slips off. And it's back on in a second, so not really any harm done. About he same amount of times the entire hose end slips off the green hose, but that's another story.  ;D

I was just reacting to ccarrolladams, saying that the oval port is actually better is in my opinion a misconception.

Please note, Alex, that I only say that in my experience the oval ports hold better. Clearly your experience is different.

In all the years I have contributed to The FOG I have never presumed to tell anyone how to do something. All I offer is my experience.

The OF1010 still uses the oval port. Many times I have used those more than several hours on a given day without the 27mm hose getting loose. It has been a long time since I used any version of the RO150 longer than an hour on a given day, yet I cannot recall a single incidence of a hose slipping off either the oval or round port.

I also have never experienced any lack of dust extraction with the oval port on an RO150 largely because I have never needed to use the full extraction of a CT22 or CT36 on an RO150.

Of course your experience could well differ.

This is truly a great source of information. I just acquired a barely ever used 150e and was wondering the exact same thing, how the heck was the hose going on it.

Guess im not missing anything.
