Smoothing Plane and Avoid Sand, Or Proceed Directly to Sand?

Many sources of info on smoothing wood state that sanding should be avoided; use a good smoothing plane and proceed to finish. Me, I get extremely thin shavings from my bench planes, but, if the board is wider than the plane's blade, there will always be tiny ridges remaining. In short, smooth with my bench planes; then a final 220 or-so grit sand.

What is your routine? Do many of you stop at the smoothing plane (no ridges)? If so, what is your technique for avoiding the ridges?

Thanks.

As a new convert to using planes, three thoughts:
1) It takes a good while to develop the technique to have that pristine surface from planing alone. I'm not there yet.
2) A bit of camber on the smoothing plane blade can help diminish the ridges.
3) there is no doubt that a planed surface looks better raw than a sanded one. I'd be interested to see if one could tell the difference in a blind test after finishing.

There should be no ridges after using your smoothing plane. You can slightly round the edges/corners of your plane blade and that should eliminate the ridges. Getting a completely finish ready surface takes a little bit of time to learn. Keep at it and you should have very little to no sanding needed.

Depending on the wood grain it is sometimes feasible
to go from smooth planing with a cambered iron. A
bevel down plane is most effective in my opinion as
cambering is simpler.

It should be noted that modern finishing standards
and expectations of near-flawless surfaces are
an expectation that is just that, an expectation.
If you look at old work the surfaces are often
not pristine and you might attribute that to wear
but in truth a lot of it may be original tool markings
and inevitable tear-out.

When the stock is agreeable I finish plane, work
problem areas with card scrapers, fill if needed,
sand to 150 grit and go to finish. I don't feel
220 is needed.

It does take well-tuned planes and good sharpening
skills to get consistently excellent results from hand
planes. Read James Krenov's books.

Stroke sanders and wide belt sanders are faster than
hand planing in smoothing surfaces to near-finish
readiness. Other sander types are not. Used
properly with agreeable wood, hand planes are
very efficient.

I don t want to sound like a butthead, but orbit and belt sanders were invented to make life a little easier while woodworking. I don t understand why some people have a need to still do it like they did 200 years ago…... Jerry (in Tucson)

This is true. Krenov had it all wrong!

All your planes are bevel up? Why is that?

I agree with Loren on grit. I do 180, but that's about it. My first big project I used Watco Danish oil on, and that's what Watco recommends. It came out smell, I've not gone higher except in special situations.

when you sharpen your smoothers, just rock from one side to the other. Count your strokes and keep adding until the ridges disappear. I would suggest starting about 10 strokes on each side. This should get rid of your ridges.

I'd rather not have a real camber. so I rock so a large part of the center I flat.

This is the big misnomer with a full width shaving. If you can get a full width shaving, you'll likely have ridges.

CharlesA - My planes (all low angle) are bevel up as I believed them to be more versatile; just swap out the blade for one with a bevel angle that is best for the situation at hand. That enables me to attack end grain (low angle) as well as wood with highly figured grain. I certainly do not mean to provoke a bevel-up vs. bevel-up debate (though they are sort of fun), but I am fully aware that either choice has its pros and cons. One con to bevel-up, I am learning, is the reduced effectiveness of cambering the blade.

Re. 220 grit, I have been, with increasing frequency, using BLO, and it seems to absorb just fine into the 220. When I use products such as Arm-R-Seal, I generally stop at 180.

I have had the same results as you. I honestly do not feel that there is a way to use a smoothing plane and get a perfect finish. There will always be ridges no mater how fine your shaving, your camber, or how you nip the corners of the blade. I use my soother a lot, but it is never the last step before finish. I usually plane then hit it with 220 or 320.

On difficult wood, I skip the handplanes. I have found that no matter how sharp I get my blade, something is going to go wrong somewhere. I will catch some grain and have some tearout. So, on some projects, I just sand all the way from 80 grit to 220 grit. Takes a while, but it is pretty much foolproof.

I talked to a longtime pro about this and he said he never uses smoothers for finishing because of the risk of tearout. Some here will probably say that if your blade is sharp enough, tearout won't happen. Well, that may be true for 1 out 100,000, but for the rest of us it isn't.

If the wood cooperates, plane it then sand it with 220 or so. If it doesn't cooperate, sand all the way.

I usually finish with a smoothing plane and then right to finish. On wood with tricky grain, I might scrape instead of plane. The only time I sand a flat surface is if it will be stained-a planed surface doesn't absorb stain well. In those cases it's a light sanding with 220 to break up the ends the wood fibers a bit.

Razor sharp slightly cambered smoother, then a cabinet scraper for the toughness areas/ surface prep, then 220 for a slight touch up before finish.

I don't like to sand too much. Not matter how careful, there is always a rounded edge that stinks of factory furniture… Ugh.

More than anything, a highly polished keen edge on any blade that hits your work…
