PM-V11 on Lie-Nielson Planes?

[Erich Weidner]

I see Veritas has PM-V11 blades for non Veritas planes.

Do any of these fit without modification in LN planes?

Blades yes; chip breaker no. The Stanley plane replacement blades of appropriate size pretty much fit.

Erich,

The Veritas PM-V11 iron fits a LN plane with no problem. The problem is the cap iron on some LN planes. Because the Veritas iron is thinner than the LN the adjuster may keep the cutter/cap iron from seating properly. It can be fixed by grinding the hole in the cap iron until it seats. Not a big deal other than being a PITA. BTW, none of my LN planes have LN A2 cutters and most needed modification of the chip breaker for the replacement chip breaker/iron to seat on the frog.

The problem lies with the positioning of the slot for the Y lever, that is, where it pokes out of the chipbreaker.

Here are three chipbreakers: Veritas, LN and Stanley. The slot for the LN is 1/4" higher than the other two ...



So, use the LN chipbreaker with the PM-V11 blade.

No modification? Just works?

Should be maybe. What I posted above still applies. Sometimes yes, The LN chip breaker with a PM-v11 cutter will work without mods. Most of the time no, The hole in the LN chip breaker will need enlarging for the prong on the "Y" lever to fit and allow the PM-v11/LN cap iron set to mate with the frog.

There are two problems with using after market cutters with LN planes. The first: All other cutters that I know of with maybe the exception of Clifton are thinner than LN iron. Because the cutter is thinner the prong on the "Y" leaver will need to set deeper into the cap iron. Often it can not set deep enough to allow the cutter/chipbreaker to mate with the frog. If that is the case the easiest fix is to slightly enlarge the hole in the chip breaker. The second problem, also an easy fix, is the different location of the hole for the adjuster vs. other chipbreakers, as Derek pointed out. The fix is to use LN chipbreakers with your PM-v11 cutter.

BTW, I could be wrong, but I think the newer your LN plane is the more likely you will have the problem. One of the reasons the LN plane has very little backlash with their adjuster is because the fit of the prong and the hole in the cap iron is so tight. The prong is angled which means as the prong engages it can only go so deep. With a thinner cutter that limit may keep the chipbreaker/cutter from mating with the frog.

Sorry to get so deep into the weeds, but bottom line is maybe.

On mine (4, 6, 7) I needed to treat the opening in the chip breaker as above and in addition widen the slot to fit over the lateral adjustment wheel. A thou or two does it. Dremel tool.

Using the LN chip breaker, I needed no blade alteration on my 2014 build (iirc) #4.

Tony,

That has been my experience, again I'm old and forgetful but I think I've only had the problem with newer planes. In a way it makes sense, the tighter the fit of the "Y's" prong with the chip breaker the less backlash of the depth adjuster. LN's "improvement" of their planes makes fitting an aftermarket cutter harder.

I have never had an issue with Lee Valley. Contact them and you will get an answer.

Rob Lee reads this forum, maybe he will repond.

Meanwhile at LN HQ, employee goes to boss: “Mr. Lie Nielsen, the latest design tweak means that the Lee Valley blades won’t fit on our planes.”

Tom, secretly smirking, “Oh, darn.”*

*I have never seen that there is much of an adversarial relationship between the brands.

Lowel,

It is not a Lee Valley problem. It is a compatibility problem between the chip breaker, cutter and frog when trying to use a cutter that is thinner than the LN A2 cutter.

Tony,

Thanks for my morning laugh ,

Main problem...IF the yoke's tab that adjusts the depth of cut can not REACH that slot in the chipbreaker, because the iron is too thick....doesn't matter who's chipbreaker you use on a plane....because you will be adjusting with a small hammer, instead...
