Hey everyone. I’ve read a couple threads about this but this is my first planer and I’m pretty new to woodworking. I bought a Ridgid tp1300 off craigslist and ran some doug fir through it today. The first couple passes the wood looked smooth and very little snipe. I was removing very little material. I took it down to about 1/16 and the wood looked awful. I started removing less again but the wood was not smoothing out. I ran a separate piece of wood and it still looked bad. Below is a picture of what i’m getting. I know doug fir isn’t ideal but I thought it should smooth out fine.. I’m making a dresser for our baby that we are expecting in February and we are just painting it. I checked the blades and they looked fine. Anyway I’ll stop rambling. Please advise.

dug fir normally has 2 layers as your planing through it. Varies from semi hard to soft leaving chip out and fuzz.

I would run some hardwood through it before determining if your blades are bad.

It’s really hard to judge blade sharpness by looking at them with a naked eye. Adding sharp blades is the first thing I’d do to a used planer.

Two great replies,if the rollers are clean and do their job,there’s nothing else other than the blades to cause a problem,before replacing the blades I would also suggest that you try a different wood to see how well it planes.

To clean the rollers,Soak a green Scotchbrite pad down with napatha (Coleman camping fuel) and scrub the rollers down,wipe with a rag ,repeat if necessary or until there’s no residue left on the rag. make sure you have unpluged the planer,watch out for the sharp blades.

It could also be caused by grain orientation. Try flipping the board around, end for end, and see if that helps. If not, it’s the blades. HD doesn’t usually have them at the store, but sometimes you get lucky and find them at their site. I’ll get mine from ebay from a seller called “brothersworkshop”. Not genuine Ridgid, but ALOT cheaper. I’ve also tried sharpening them on a homemade jig and sandpaper with marginal results.

Yikes! Coleman may make a naptha stove fuel, but the Coleman stuff I get in the gallon cans is white gas—much too volatile to be safe for that kind of use. Actual naptha or paint thinner is much safer.

I’d recommend sending the old blades off to get professionally sharpened so you have a fresh set of blades ready to go. Usually about 1/2 the cost of a new set of blades give or take. I had 3-6” & 2-10” knives sharpened for 28$ a couple months ago.

You never know if both sides of the blades are used, but you can always flip them around to see if they other side of the blades are sharp. I thought the blades in that kind of lunchbox planer are meant to be disposable. New set of blades is pretty cheap. 2 sets for $35

In that case. New blades.

I get my Ridgid “disposable” blades resharpened and they work better and last longer than the new ones.

Good advice above re: flipping the blades over and planning from the other end of the board. Some dampen the surface of the board with a wet rag and they claim it helps prevent tear out.

It also looks like there’s a small knot near where you’re planing. I’ve noticed many times that around areas like that, the grain direction gets a little screwy, it may be going one way up to that point, then switch 180 degrees. If that’s the case, you may try misting the board there before you send it through, or getting close to thickness and then switching to hand planes.

Or, it could just be lousy wood, or bad blades.
