How to Fix a Clogging Hand Plane Mouth | Hand Plane Foundations

Welcome to my Hand Plane Foundations course. In this course I’m going to introduce the different types of bench planes and discuss their setup and use, focusing on the planes you’ll need most as a new hand tool woodworker. I’ll cover sharpening the iron, setting up the cap iron, and troubleshooting and tuning the tool up to perform at its best. I’ll finish up by building a modern two tone cutting board from some beautiful North American hardwoods, completely by hand. You can view the full course here:

    Where was this video several yeara ago when I found my dad’s No. 6 Stanley and it got clogged up so often? It took me a long time to figure it out.

    Looking at the video at the 3:45 mark or so, surely that is not the setback of the cap iron from the edge of the iron? I’ve always heard that you shoot for about 1/32 of an inch.

    My problem is that, the mouth is small for the blade so, When i advance the iron forward for heavy stock removal there is almost no gap between the blade and mouth opening. And if i try to put frog back to compensate it, then there is not enough adjustment that blade almost not stick out. And tried bunch of times for the find a sweet spot but failed its either too close or iron can’t stick out. And i did file the mouth to open it but at one point it felt like i’m taking off to much and might effect the integrity of the plane idk. Is there any guidelines to look for for fixing this issue?

    Thanks Bob. One of the things I do to my well fitting cap iron is give it a few swipes on my strop after I sharpen and strop my iron. My thought is that during use, sap and resin can build up on the cap iron and a few swipes on the charged strop (keeping in mind the angle like you did) cleans off any gunk build up.

    Perfect, I just finished cleaning up my new (to me) Record No 04 and I needed to find how to properly dress the cap iron 🙂

    I like that you speak of a capiron rather than a chipbraker. In my opinion that’s what it is and it’s a myth that the capiron breaks any chips. Setting it close to the edge helps stabilize the blade but have no Interaktion with the cuttingaktion. What’s your opinion?
