I’m in the market for a block plane. I’ve read the reviews of the Lie-Nielsen planes and the Veritas planes. I’m sure I can’t go wrong with any of them. They seem to be such high quality. My question is about the Lie-Nielsen low angle 102 – the one without the adjustable mouth. The 102 seems great for lots of things. Comparing the 102 to the standard block planes with adjustable mouths – i’m wondering how often I’d actually adjust the mouth. It’s probably set pretty thin. Cost is also part of the issue. I’m also wondering how necessary it is to have a heavy block plane like the 60 1/2 low angle. Does anyone have both the 102 AND the 60 1/2? Or can anyone comment on block plane preferences and how they’re actually used?
Thanks!
Mitch

Every time that I need to, which an be quite often depending on the work I am doing.
This is kind of strange question.
If you have choice buy a plane with an adjustable mouth even if you really use it, when you need it you have it.
A block plane is one of the most used tools in a shop.n
Normally you have more than just one, I have at least five of them.
I personally prefer Veritas plane, not saying that LN are not good.

Not very often, but the ones lacking adjustable mouths are
usually too big in the mouth.

I recently upgraded from a fixed mouth to adjustable mouth and it has made a world of difference. When doing things like chamfers on open grained woods such as oak, it made all the difference between a nice smooth chamfer and something with bunches of tearout. I just set the mouth pretty thin and go my merrry way since I never use the block for hogging off wood. I do want to get a smaller “apron” plane at some point, but it’s not really necessary for the time being.

Thanks, everyone. Ripthorn, that’s exactly the kind of information I needed. I’ll do quite a lot of chamfering with the plane, so having the option to set the mouth very thin sounds important.

I have a block plane without an adjustable mouth; it sits on my shelf because it tears out the wood. Conversely, my LN with an adjustable mouth gets used all the time…

I believe that you should always get all the options you can afford.
Many time I bought a tool not knowing really why I was buying it but after having it, I found myself using very often.
I believe that an adjustable mouth on a plane, if available, is a no brainer as it offers so many more options.

I adjusted the mouth on mine the last time I picked it up. Or “as needed”.

More often than I expected… I’ll open up the mouth for heavier stuff, like looking at rough boards at the lumber yard or quick stock removal before I macine a board. I’ll close it way small for end grain and finer edge shaping cuts.

I also have some fixed mouth block planes that work OK, but if you CAN move the mouth, you can always choose not to…

I adjust the mouth nearly every time I use it on my Stanley 60 1/2 low angle block plane.

Its like asking “How many time do you adjust your car mirror”. You may have only adjusted it once when you bought the car, but if you couldn’t adjust it it would be a life time of neck stretching.

That said, I adjust them a lot.

If you have a fixed mouth plane, low or standard angle, then you can set& forget the adjustable mouth ones. IF you have enough of them set each a little different, and grab as needed.

fairly often in my case for different tasks. What you really want to know is ‘IS AN ADJUSTABLE MOUTH REALLY NECESSARY?’ I can say yes in my case.

I often times adjust my LV LABP a couple of times when working on a piece.

Lee Valley has great information regarding shaving types, that info comes with the user’s manual of their planes, Im sure they will send that info to you for free…..Mouth opening and blade angles are the most important issues on avery single handplane.

Why to move a frog on a conventional Bench Plane?....for the very same reason!
The answer is simple: to close the mouth. Tear out on many woods can be reduced significantly when having a tight mouthand it is esential for crossgrain work. Since Block planes and Bevel up’s do not have mobile frogs, thats why they have that mobile plate at front, that allows to close their mouth.
