Hi everyone,

In another post, I noted that my first and only Festool purchase is the CT22. (We matched the 22 with an electric concrete cutting saw and cut over 200 lineal feet of concrete indoors and did it with virtually no dust escaping the vacuum attachment). 

As we were finishing up that job, my customer asked for us to pull some trash out of the basement.  One item was an old workbench.  One of my men called me on the phone and said "Rob, you have to save this workbench-wait until you get here and see the lumber that was used to make it....and there are two vises on it, as well."

I was amazed once I arrived and looked closely at the lumber....it is clear fir, very old,  with maybe 20+ growth rings per inch on the visible ends of some of the planks that make up the top. I decided that I need to clean this thing up and use it in my shop.  It is covered with 50+ years of paint, stain, varnish, and other assorted spills and messes.  At frst, I thought about running it all through my surface planer, but now I think I don't want to lose any thickness of wood if it can be avoided, and some of the pieces are warped a bit and should be dressed before hand with a large jointer (which I dont have).

Then, when I looked in the Festool catalog and read some of the threads here, it seemed to me that maybe the RAS 115  would do a fine job stripping the finishes off of this thing and getting it down to bare wood.

A related project is to restore/refresh/refinish the workbench I have that I inherited from my Grandfather, which he built by hand in the the early 1940's out of oak he salvaged from his job at the lumber yard.  This bench has seen tons of work and would look great stripped down and refinished.

So, my goal is to get both benches down to bare wood with as little damage or wood loss as possible.  My two enmployees are painters and finishers, and have done a lot of work on our jobs with wood finishes, so I am in good shape with the finishing end of things.  I own a detail sander that will work in the nooks and crannies, but I want to get the proper Festool sander to hog out the rough work.  I could have them use some of the miscellaneous sanders we already own (Porter Cable, DeWalt, Ridgid), but I don't want them breathing the dust and like the option of running the 22 along with the sander.

I would appreciate any feedback that anyone can give me, as well as suggestions for the best abrasives to buy.  I see in the catalog that there are a lot of options.

(I tried calling a  local Festool rep that we met at  product demo day, and all but told him that I was ready to hand over my credit card and let him start selling tools...but he has never returned my a calls.  Business must be good....)

 
Rob:

Cristal is probably the abrasive you're looking for. It holds up well and doesn't clog easily.

I personally would go with the Rotex 150 just because it is a more usefull all around sander and can handle the job you described. The RAS 115, as Mr. Mann pointed out, can handle the job but it is a different beast altogether.

The RAS is a high-speed rotary sander, the Rotex is a dual-mode orbital sander.

The Rotex has a gear-driven orbital mode that can do some serious material removal or polish. It also has a random orbital mode that is great for finishing. Because, in gear-driven mode, it turns slower and orbits it can cut a lot without slinging what it cuts as much as something that turns at 4000 RPM (the RAS). If you are concerned about dust control and want, arguably, the best all-around sander on the planet, go with the Rotex. If you just want to cut through stuff quickly, go with the RAS.

Greg-thanks for the correction-I misread the catalog while I was typing.

Tom-thank you for the detailed information.  I will go and review the catalog and come back with any questions I might still have.  Thanks!

 
The Ras is a low speed High torque sander, and it will eat the finish off and just about smooth it out with all the higher grit papers available for it.

The RAS is awesome.
 
RAS 115 with Cristal 24  is the right tool to take it down to wood and then any orbital sander to finish the job with very little effort. The RAS 115
dust control is good but it will leave the big chips of paint flying around the room.

I just finished two projects with it and find it to be another remarkable Festool.

There is no Cristal available for the RAS.  Just Saphire and Rubin.

I did not know what to expect when I got this sander.  Let's just say this Festool might be my favorite.  It is really a powerful tool.

I have logged about 30 hours so far with it and have been totaly impressed.
 
The 24 and 36 grit Saphire reminds me of the soft disks we used to use on the big angle grinders to clean up steel.

P.S. I sharpened my lawn mower blades with the RAS just to see, I think it might have done better than my grinder.
 
I ended up going with the Rotex, planning on being able to use it on the jobsite, as well. It's on its way and I will test it by this weekend.

I'm slipping down a slippery green slope....... LOL.
 
I got the Rotex first, it does a good job.  The RAS has cut my time in half for finish removal though.
