cap iron adjustments ( like in the japanese video ) wont let my LN blade protrude....

[John A. Callaway]

So I took my 5.5 and was going to see what I could figure out in reference to the recently found video of a cap iron's placement and how if affects ( prevents ) tear out in any direction.... I got the blade super close to the edge, almost to the point that a magnification was needed to make sure it didnt stick out over the edge of the blade .... trying to find that .2 millimeter... and I can get it adjusted very close to that point, but when I put the set up in the blade, and move the frog forward and back to find the right set up that works, the depth adjuster wont let it down far enough to clear the mouth of the plane... The round hole in the cap iron for the hold down screw causes the breaker to bottom out on the screw ..... So I dont think this is gonna work without altering the hole some, and then the tang that moves the blade forward and back will drop down to where it wont catch on the blade.... so I dunno ..... I am sure in a japanese style or Krenov style plane this will work okay.... and I didnt try it out in my old stanley number three.... since its got frog problems.... but I could give it a try and see ....







I had it closer than this, but I encountered the above problem.... this was pushing the limits of the depth adjuster's travel and mouth opening....

Interesting. That looks like a considerably smaller hole than the somewhat ovoid holes on all the chipbreakers I have.

I suppose you could just grind a bunch off the working end of your iron . . .

[James Taglienti]

Grinding the cutter wont do anything for you but you could file the chipbreaker hole.

[Chris Griggs]

Thats odd. I've had that problem, but only on old planes where someone had previously ground back the leading edge of the CB. I would send the pic to LN and ask what they say. They will be more than willing to advise you.

[bridger berdel]

you need a slightly longer cap iron.

[Jessica Pierce-LaRose]

Oops - Never mind, I get it.

[John A. Callaway]

It looks like I would need maybe another +/- a quarter inch of room in the chip breaker hole..... and that still wont solve the problem of the depth adjuster running out of travel... although, i guess if the chip breaker had more travel it would most likely eliminate that problem.....

I wouldnt really know what to ask LN..... that I am trying to get the tool to do something it really wasnt designed to do.... as far as a set up procedure goes.... I dont think they designed the tool to have the chip breaker so super close to the edge of the blade... so I dont think this is something I should call them over.... I am sure the would most likely send me a new chip breaker.... but it will most likely be set up the same way.....

I guess I will have to set out and just build me a krenov style plane.... perhaps a hock kit first, just to learn the process.

I would call them and ask them if they intend the chipbreaker to be able to make it all the way to the edge of the iron with the iron at full depth. If they don't, there is a design flaw (especially considering that the edge will take some wear when used properly and have to be polished from time to time). I haven't tried to fiddle with my lone remaining LN plane yet (#7) because I haven't used it since we started this playing with second irons.

But it is a design flaw straight away if you can't advance the chipbreaker all the way to the cut in use.

[James Taglienti]

How far is the chipbreaker from the edge usually? Its got to be within 1/16. They must have engineered more travel into the adjuster than that. Is your chipbreaker altered?

[Jim Koepke]

If possible, my first check would be to measure the distance from the bottom of the slot to the edge of the chip breaker and compare this with another chip breaker of the same size.

There is a chart of such measurements here on SMC, but it only covers Stanley chip breakers.

Maybe some one can supply the measurements from one of their chip breakers if you do not have another LN plane using the same sized blade.

It's usually up a little farther , some where just under an 1/8" from the edge of the blade... I used to think I ran it down fairly tight to the blade edge, and it has never given me a problem.... until I saw this video, and tried to run it down even farther....

[John A. Callaway]

has anybody else got a four or five from LN they can see if they encounter the same problems....

[David Weaver]

I can check a 7 tonight - it'll have the same frog/iron/cap asssembly as your 5 1/2.

I have an LN #4 and #4 1/2 with 55 degree frog, and they both have plenty of travel in the blade adjustment mechanismfor this setup. I also have a LN 5 1/2and interestingly it seems like it would be right at the end of the adjuster travel with this kind of mouth set up.

You might want to try Moving the frog farther forward and see if you need less blade travel to achieve the same mouth opening.Just thinking about the geometry, it doesn't seem like this would make a difference, but I'm not nearly smart enough to know for sure -- I generally go with the "try it and see" approach.

I would be interested to know if you hear anything from Lee Nielsen about whether they intended the #5 to be set up this way.

That is odd. I have been taught and have seen many video's that state the chipbreaker should be within at least 1/16" of the edge of the iron. I have 4 different LN planes that I practice this on, one of them being a #5. I typically set it closer to a 1/32" and have never even come close to maxing out the travel of the adjuster.

I do not have a LN 5.5 though so am not sure about this setup. It would seem that they would've designed the plane to be set up with this 1/16" or less and have no issues. Very odd.
