I just salvaged an old baby crib someone was throwing away. Made of all solid wood. I took it apart and cut (to length) all that could be saved. The wood has an old finish on it (starting to flake off) – Can this be run through the planer to get all the finish off, or get down to the bare wood? or will this ruin my blades?

Personally id run it through. If theyre disposable blades, ya pissed away $30 but got clean wood. You could also flip em over if theyre 2 sided as well. The other option would be belt sand the wood or hand planing. I think id take the risk of running them through. I think the only way it would totally ruin your blades is if it had some sort of aluminum oxide finish on it like prefinished flooring.

I’d run them through. The alternative usually takes time…which is money…which costs as much as new blades anyway. It’s arguably hard on blades, but it will not ruin them immediately.

you can tell its a crib that was manufactured by the 1000’s….it has a very thin finish on it… and some of it is flaking off

I do it. I have a sharpener for my planer blades though
so it doesn’t cost me anything but time to fix them up.

Sometimes if I am not sure about what’s underneath the
paint, I’ll hog it off rough with a hand plane to get rid of grit
and check for metal.

The finish, “varnish & paints” will dull the blades, a nail or piece of metal will knick the blade.
An option is to have 2 sets of blades , use one set for removing finishing and other set to plane raw wood. Might save you sharpening blades each time.
I have a dedicated 6” jointer that I only use on used lumber, another jointer for RAW ,clean lumber.
I don’t run used lumber through my planer, I use a drum sander if I am not sure.

You may want to check for lead before planing or sanding that finish.

If it is a stained finish, it will be lead free. If it is paint, it certainly may have lead, and be risky.
But if a lacquer or varnish finish it will almost always be a one piece spray type finish with color put in for one coat production work. It may even be a water base, being a baby crib and all.
Start planing, I don’t see where it will damage. Lot better edge and more level than sanding it off, and you can vacuum up most of what comes off from your planer.

As an alternative if you’d like to avoid wear on your planer knives, if you have a card scraper that’s fresh and sharp, it should be able to remove a fair amount of the finish, if not all of it.

I take a strong neo (Neodymium) magnet in my hand (hold it like a pencil) and quickly slide it over each piece of wood. You’ll quickly find if there are any hidden nails when the magnet tries to grab any metal object. You probably don’t need it in this case, but works great for old boards that you are trying to salvage.

The “neos” are the strongest magnets around, last forever, and have the strength to ‘grab’ hidden nails. (It doesn’t pull them out, just shows you where they are).

I have used these small magnets to detect hidden metal several times.
It works amazingly well. When the magnet is over a nail or screw it will move
right to the location.

The potential of metal is definately the thing to worry most. Any finish will tend to build up on a blade (planer, jointer, circular, band, etc), making it seem dull; a quick cleaning with mineral spirits will fix that so if that is your only worry, have at it!

Yeah those magnets are awesome. I use them frequently. No chance of nails in this wood. Just wondering about the finish affecting my blades. Just got a new planer – don’t want to mess it up already
