Thread: How to arise?

You can use anything, plane router sandpaper file. I personally use a 6mm rouning over bit on most of my stuff.
It really depends on the look that you are after.

Lots of choices, really. In addition to Specialist's suggestions, I recommend a very small (3mm) rounding over bit to give it just that bit of easement.

Correct spelling is "arris." Strictly speaking, arris should be sharp, but uniform rounding is less prone to disintegration, or harm to materials contacting it, such as flesh. The key is uniformity full length. I would suggest the smallest amount achievable; you could start with fine sandpaper and experiment.

The English language is a Work in Progress, and "arris" has pretty much become a term for the rounding itself, in spite of the original definition.

Depending on the effect I want there are a few choices.
Router, stopped using router years ago as everyone uses routers and it got ho-hum for me
Handplane, quick and easy, lots of control.
Electric Plane for a wide chamfer, usually only on rough sawn timber.
Sandpaper, my most preferred arris for furniture

Me personaly, though i havent done much woodworking i just use sandpaper, not to round it as such just to take away the sharp edge, it still looks sharp but it isnt...

Roundover bit if I want a quarter circle. Otherwise a few quick passes with a hand plane. A bit of sandpaper if I want to round it.

Just about any tool with a cutting edge can be used in some manner to arris/break an edge.

I like the dimension of 3mm rounding over or perhaps 2mm. I find it tricky to get a good finish using a router for that without stuffing up along the way somewhere. Sandpaper is risk free.

Best things I ever got for sanding are hand frames for sandpaper (look a bit like a plasterer's flat trowel). I have a large plastic one takes that special long slotted paper (or grid sanding stuff for plasterboard) and has thumbscrews to hold the sandpaper. I just got a small one from B's by Rokset made of metal that takes about a third of a standard sandpaper sheet lengthwise and has cam lock levers on each end. Just been using them to sand VJ walls including getting crud out of the VJ grooves.

Sanding frames make sanding like planing (ensures flat surface) but no trouble with wrong grain direction tear-ups.

3mm is a chamfer. An arris is just the sharp edge removed, around 1mm at most

Hmmmm......

According to the dictionary/wikipedia, an arris is just an edge between two adjoining surfaces. http://en.wikipedia.org/wiki/Arris

In local parlance chippies working on our house used arris as a verb meaning to take the corner off - in practice that meant a small chamfer of 3-5 mm. But I can't find a dictionary reference to this usage yet.

A arris to a chippie is usualy 10-15mm

The term "arris" refers to the corner. The phrase, "to arris a board", in trade terms is to remove the corner. Carpenters usually arris timber, or remove the corner. Often the corner is bruised or damaged during transit and "arrising" will tidy up the timber, mostly with a hand plane.

The terminology's correct as defined.

The arris is technically the sharp corner between two boards, to "arris the edge' is the term used to knock the sharp point off so you don't cut yourself or any one else, using a fine set hand plane or a bit of sandpaper, so that the edge is blunt but the boards still appear square - maybe 1/2mm chamfer or so.

Perhaps, more technically, you could say: "remove the arris" and people would also understand what you meant, should you choose.

FWIW,

All sharp edges I arris are done with whatever plane is appropriate, depending on size.

Merely hold at ~45deg, and take careful shavings until desired effect is achieved.

simple
