Shaping a chair seat with a RAS
« on: May 21, 2019, 10:15 AM »
Hello all;

I'm interested in making some walnut dining room chairs, I was wondering if the Festool RAS would be a good choice to shape the bowl area of the seat? I watched Shaun Boyd use a Kutzall carving wheel on an angle grinder to do it but I like the idea of the dust control found on Festools.

Any thoughts or suggestions would be really appreciated!

If you want to work fast use a grinder, the RAS will also work, but much slower, and you should definitely not expect too much from the dust collection on a job like this. The RAS' dust collection is pretty poor on a flat surface already, let alone on a cupped surface.

I'd probably lean towards a Rotex with a soft pad and a decent grit selection. Use a pull knife to get your initial shape and then finish it off with the Rotex.

I use a HL 850 planer with a undulating HS 82 RW planer head to rough the seats out. I then use a RO 150 to smooth them out.

Scorp or inshave is a proper tool for hand shaping chair seats. There are one or two handed types.

It is as fast but more forgiving than angle grinder and definitely more efficient than Rotex. Choose cutting over abrasion, shavings over deafening noise in the midst of a dust storm. Refine with travisher.

Hello all;

Yes - in my opinion it is the perfect tool for this application - 24 grit or 36 grit Saphir will work very well and last a long time. The DC is not great, but the fine dust is captured and the bigger saw dust drops to the floor or bench and is easy to vacuum. I found the RAS to give great control and the speed was fast enough to remove material well but not too fast to risk mistakes or as big of mistakes. I have made 5 walnut Maloof inspired chairs with the RAS and Rotex sanders and it worked perfectly. The RAS and RO90 can get the job done and I found a Rotex 125 to be the perfect middle sander size to smooth the seat with interface pads. This trifecta of sanders worked extremely well for me.

Here are a couple of quick videos of my using the RAS - not the best quality, but I did this one handed and you can see the control this sander gives.



And this one is shaping an arm - again, one handed.

I think I’ve posted this in one of the other threads, but I used my RAS 115 to sculpt most of this rocker. I started with the holey galahad wheels, but there was no way of controlling the dust so I got the RAS.

It will be followed up with rasps, and RO90 and RO150.

There is a learning curve on how to best maximise dust extraction with turning the handle, and although not perfect it’s still not bad. Highly recommend it.

Thanks for that.  [smile]  I don't have an RAS but I am surprised at how well it controls the fine dust. The stuff that gets in your eyes and obscures the work surface.

I'm also impressed with the one-handed control. The Milwaukee grinders I use would be more difficult to use one-handed.
