Hey All,

I’ve been thinking about finally getting a block plane. Over the last few projects I have run into several situations that I thought one would be useful. The only plane I have is an old Millers Falls #4 and that’s what I end up using each time I think a hand plane would do the job best.

The thing I can’t quite figure out is why you would need an adjustable mouth on a block plane? I read through the following post but it never really answered the question what an adjustable mouth does for you. What I did find interesting were a few people saying they had both an adjustable mouth block plane and an apron plane… and often chose the apron plane.

I’m all for saving a few bucks if possible. I’d still rather buy a new one (Veritas or LN), but the apron planes are cheaper. More often than not though, I tend to buy the cheaper option only to buy the more expensive option later on, defeating the original goal of saving money!

It helps for the mouth to be as narrow as you can get it, the thinner the throat is, the more you are supporting the wood fibers and preventing lift and tear out. Theoretically this is more important for a bench plane, but i use my Veritas for plenty of situations that i could possible encounter tear out with.

The adjustment is for chip clearance depending on how big of cut your taking.
