Is the 24 grit as vicious as it sounds? Anyone ever tried it?

It's either that, or some sort of rasp bit for a grinder, like the Saburr - but there's no dust collection then.

My plan is to shape some bowls/trays in interesting ways. I've got a bowl bit for my router, but something more organic looking is the theory. Think kidney bowl with differing depths...I know, lovely right? Worst description ever, sorry.

Anyone have any other solutions?
 
Take the dust. I'm not impressed by the wood removal properties of any Rotex sander. Good to even things out, but not for sculpting. A grinder is very much faster. Only Festool sander that could do it is the RAS 115 (or 180), but that one IS basically a grinder.
 
I've used Rubin 24 on the Rotex 150, and found it to be quite aggressive.  The RAS does hog out more material, but the Rotex with Rubin will do a good job for you.

It's just  a matter of how much you need the sander to do versus how much you can remove ahead of the sander with other tools.
 
P24 is only available in Saphir, not in Rubin/2.

I used it on a RO150 to strip shellac, it worked okay, and wasn't fast by any means. I'd do an angle grinder for shaping for sure, though dust collection will be a challenge.

I could forstner loads out on the drill press, but that leaves quite a mess to deal with and wouldn't go with the whole organic feel. I guess I could try one of the smaller Saburr bits to get rid of most of the material. I was a little concerned that the larger one wouldn't be very directional in a tight space.

Saphir P24 isn't available for RO90, chart I am reading says Rubin is though...unless it's out of date.
 
Wuffles,  It sounds like you are wanting to hog out more than what  sander will do easily. Like Alex said, a grinder is likely the better choice.  I've seen attachments like this and wish I had a (paying) reason to buy one and try it!

It's probably out of date... either that or http://www.festoolusa.com/abrasives is wrong. :)

Right on. [member=101]Shane Holland[/member] might want to get this file (http://www.festoolusa.com/Web_files/Abrasives_brochure.pdf) updated as it showed up near the top of a Google search I did. I'll bookmark the other link though. Cheers guys.

The arbotech looks pretty cool, perhaps less mess than the Saburr rasps? [member=6270]woodguy7[/member] might clarify as he's used the Saburr I think.
 
Sorry mate, was someone else who had one I guess. It's a proper vicious rasp bit for an angle grinder.
 
Right, it's now a toss-up between the Arbortech Woodcarver Pro-4 (as it can be had for as little as £34 if you just want the blade) or one of the smaller Saburr files. I'm leaning towards the Pro-4 as it's possible to sharpen it with a chainsaw file.

The P24 grit appears only for the Delta head on the RO90, so that was a non starter anyway.

 
Oh yea, that thing.  Sorry, i forgot what it was called.
Yes i have used it a few times now.  I have the medium grit one & i wouldn't go any courser than that.  You can do a lot of damage real quick if not careful.  Great tool for sculpting though.
 
You can always get a bigger disk and cut it to size for your sander. It is just that for this application a sander is nowhere near fast enough, not even with 24.
 
So, decision was made, changed, made again. Went for both the larger Turboblade and the smaller WoodCarver Pro-4 in a set. Whilst one seems to be able to get into smaller spaces, it looks like it won't follow a template and is more vicious, whereas the larger one seems to produce a finer cut.

Just need to finish it off with the packet of 40 grit I bought when I got the RO90.

More things to play with when the sun comes out. Can't imagine firing either of the Arbortech products up in the workshop.

I'm reasonably handy with a chainsaw and an angle grinder so a combo of the two ought to be easy right?

Ha ha. Seriously, I will treat these with the utmost respect. Can imagine kickback must be pretty high on the agenda for these things.
 
If this is more than a one-time thing, you owe it to yourself to invest in a Metabo angle grinder.

They have really nice usability features like an autobalancer, soft start, constant torque output (which helps predictability more than you'd think), but also has a safety clutch to decouple the motor if it ever catches, auto-brake, and a motor lockout that prevents the motor from spinning up if you plug it in with the switch on.

Even if you don't get an autobalancer, they still have the lowest vibration of any grinder I've ever picked up. I have DeWalts, Makitas, and a Fein, and the Metabo is really head and shoulders above anyone else. As they should be, its been their core business for decades.

Bought a variable speed Metabo a year or so ago after my trusty Bosch (which had been going for years under duress) blew up catastrophically.

I don't think I could entertain these wood cutting blades in a non variable, lunacy surely?
