Topic tags/keywords: planer snipe gauging nicked cutter blade ridgid r4133 thickness pine question

Hi All: Just fired up my brand new Ridgid R4133 thickness planer. Worked out settings to get zero snipe (nice) but, I’m seeing something my limited experience cannot explain. Maybe a nick in the cutter head(s)??? I’ve heard the term “gauging” but have insufficient knowledge to visualize what that might look like on my planed stock. Best description I can give is my planed stock has a baby bottom finish, no snipe, but, depending on where I insert the stock on the infeed, I end up with a small line (ridge) traversing the length of the stock. Is this “gauging”? If so, is it caused by a small nick in one or more of the cutter heads? Any other suggestions? My planer is less than 48 hours old and I’ve only ran 5 thirty two inch 2×4 stock through it where I’ve cut 1/64 inch off each side, alternating sides until each piece was one inch thick… no nails, staples, etc. – brand new stock from the lumber yard (pretty clean pine, a few knots, but not many).

Thanks for any help.
Cheers,
Probie61

Probie61, I’m not familiar with the term “gauging,” but it does, indeed, sound as though you have a nick in one, two or three of your blades (I’m assuming you have the R4331).

nothing a little sanding wont take care of which you would more than likely need to do anyway. You probably nicked a blade or two during setup or perhaps it even came that way from the factory. Not unheard of.

It sounds like there is a nick in the knives. The factory knives for a lunchbox (LB) planer are soft. You can fix this by sliding the knives. If it is a 3 knife head then slide 1 left and 1 right. This will misalign the nick so the next knife will cut off the vein left by the nick. I have done this a few times when have nicked my knives. I have 20” knives so they are costly to sharpen and/or replace.

either a nick in one or more of the blades – resulting in a ‘raised’ line (unplaned), or debris on one+ of the blades resulting in a gauge or deeper groove in the board.

neither is something to get overly excited about as they are expected side effects of a thicknesser. remember – this is NOT a finishing machine. this is designated as a milling machine = rough work.

if it’s a deeper groove it means your blade(s) have something stuck on them – open the cutterhead, and clean the blades properly to remove any such debris.

If it’s a raised line it means at least one (probably more) of your blades has a nick in it. you can open the cutterhead, and try sliding one o the blades (the one with the nick) slightly to the side to create an overlap between the blades to clear that issue. or just deal with it when it comes time for finishing , or with a scraper (about a 3 second process).

Cheers, and a Happy new year!

Thanks to Mark, Scott & Shawn! You guys are great! Quick responses – I am very grateful… Now… Hmmmm.

It seems unanimous – Steve (me) has nicks in his blade(s)!

Since this Ridgid R4331 is brand new (four days old today), what is the experience any have had with regard to their “lifetime” warranty” on “errors out of the box” kind of thing? I certainly can understand that cutter blades would, under normal circumstances, NOT be covered… but really, they shipped it that way? I cannot imagine a blade getting nicked in shipment! Then again, I can also see being told “Hey Probie, it seems your inexperience with power tools caused you to nick you blade(es).” (Though I know that NOT to be true!)

Hey Shawn: GREAT idea! Thanks! Tipping my hat to you for increasing this big Probie’s knowledge/experience (wait until I come back to describe my experience in trying THIS one! (chuckle!).

Sanding can certainly take it down – it is something less than 1/32 (probably much less – my eyes are still in training)!

Scott: You wrote: “Not unheard of.” Really? Blades can come from the factory already pre-nicked? Is this just a “suck-it-up Probie and move on” deal? (smile)

Again, thanks so much guys!

Hey PurpLev: Thanks much! Today I’m going to move forward with the “opener up” path and see if I can figure out the process for sliding blades around… perhaps I can even get these old eye to stare at the blades and just see if I can see the nick.

Say, I’m pretty good and sharpening knives… I’ve never seen a cutter blade before (I will by the end of the day though)... can one sharpen these things themselves or does it require a special machine (tool) to getter’ done?

Oh, thanks for the reminder – I need to WRITE down ”...buy a scraper..” on my to do list today!

ALL: Before starting up again recently, the last time I cut wood was about 40 or so years ago – it appears to be made of the same stuff though! (chuckle) I just don’t remember the sound effects that seem to come with picking the big timbers up!

That pine you planed initially could have nicked a blade with those rock hard knots pine (and cedar) are prone to. You can easily shift those blades a tiny bit from side to side which may eliminate the ridge.

I send my Ridgid ‘disposable’ planer blades out to be sharpened and they cut better than new and last longer! BUT it does cost me $25 to get a set of 3 sharpened on both sides (new set costs $30). It is $25 well spent for me.

if you bought this from a box store it has staples & tags in the ends I think ,but if it come from a mill you should be OK I think again

I know my Ridgid TP1300 has indexed blades and cannot be shifted side to side. I can’t say about your model, but I know the stock knives do seem to be made from a softer steel. I made a jig that hold the knives at the right angle, so I can sharpen them. I can get them sharp enough to hold me through until I can get a set online, as HD doesn’t have them in stores anymore. Although I really like my Ridgid, if/when I replace it, it will be with a DeWalt 734 or 735. You can get blades anywhere for them.

Madwood, Even though they are indexed, they can be shifted side to side by 1/16-3/32” which is often enough to eliminate the ridge caused by a nick in the blades.

Slide the first blade all the way to the left, the second all the way to the right, and center the third one.
