Video of how to use rasps
« on: May 04, 2012, 12:59 PM »

I am often asked to explain how to properly use a rasp.
Rather than a long and tedious speech, I had the idea to film as an example a cabinetmaker near me doing a "deer foot" for a cabinet.

Excellent. Thanks for that.
I suspect that's not his first time.

That was interesting.  I could see myself destroying several pieces before getting one correct.

Liogier, Thanks for the video.  
I'm curious about your thoughts on the rasp technique -- the artisan in the video is obviously highly skilled, I notice that he drags the rasp back resting on the work piece on the return strokes as he gets ready for his next pass.  The use & care instructions written by Michelle Auriou (I have several of his rasps) seems to support this same technique.  On the other hand, Christopher Schwarz warns against this technique recommending that the rasp be raised off of the work piece on each return stroke to avoid premature wear.
I guess the question might be how premature is the premature wear?

Thanks again.

IMHO, using a rasp should stay easy, intuitive, comfortable and keep you full control of the shape you desire to obtain. For this four reasons, I tend to believe that there is no other way of rasping than keeping the rasp in contact with the wood.

I would imagine his comment speaks to the overly fugal sensibilities of most wood workers, many of whom scoff at the idea of a $100 rasp, more than functional technique.

With all due respect to Mr. Schwarz, it seems pretty apparent which technique I'd want to emulate just by watching the videos.

Absolutely true -- Mr. Schwarz is way out in "left" field in his private life so I take him with a grain of salt although he certainly knows quite a lot he isn't always on track.

I dipped my toes in the Auriou rasps & bought just one -- when I found how amazing these hand cut rasps are I now have several.  They are nothing like any other machine made rasp for finishing wood.  [eek]

I'll certainly be giving the Liogier rasps a try -- I have no doubt they compare favorably to the Auriou rasps.

Well said.  It isn't like you're putting all your weight on the rasp on the backstroke.  In theory they are a bit harder than the wood, too :)

I leave it on the wood; helps keep the same registration, goes faster, and in the end... it doesn't look at all like that artist's work!  [embarassed]

I drooled over that site's products the first time it was posted here; in fact, it is still an open tab on this shop computer (guess my online to-do list doesn't get much attention :)

The Iwasaki 'plane' files are quick for shaping and leave a smooth surface.  I use those before my pre-Brasil Nicholson #49/#50.  How smooth do the fine grain rasps get the surface?

Technique aside, those hand made rasps seem to be a whole lot better than the hardware store ones I purchased long ago and now seem to be "useless'.

I would spend the money on a set of these hand made tools if I did a lot of curved joinery and I wouldn't worry about keeping the tool on the wood on the back stroke.

Thanks Noel,

That clip was excellent just like your rasps. I love my Liogier rasps so far but I am in awe watching that that video.  [eek]

I'm like Paul in that I keep a bookmark on the manufactures web site waiting for that one job that comes along that will encourage me to buy a set of those fine tools.

Thank you. If one of you plan to come to France, I hope you will have the time to stop and visit the workshop. Woodworkers from around the world are always welcome.
Regards,

Noel

J'aime la façon dont il s'est concentré sur votre travail comme si rien d'autre ne se passait autour de vous. J'ai râpes découvert que récemment et les utilise tout le temps maintenant. je vous remercie.

I would love to do this. But afraid all my cabinets would have to be "one legged".

Thanks for posting this. I enjoyed it.

I agree... I can't imagine having to repeatedly line up the rasp with every stroke.  A waste of time, and it would be all over the place.  It would be no different from lifting a hand saw off the workpiece after every stroke...

Something that only called for one or two strokes with a rasp I would probably do with a file or with sandpaper.
