I’ve been watching videos and reading about krenov planes, for my first attempt….

1) Mixed guidance on gluing vs not gluing the cross pin. What do you all recommd?

2) should the cross pin be flat bottomed? I’ve seen this a few times (clearly this one shouldn’t be glued).

3) does a chip breaker matter at all on a jointer? Mostly going to work edges vs flattening wide boards

4) do folks recommend the plane iron sticking up farther than the wedge, or vice versa?

Going with Hock 2” x 3.5” unless recommendations otherwise.

1. Do not glue the cross pin. It rotates. It is also not a round pin but a triangle. Look at plans – this is the heart-and-soul of the Krenov plane.

2. see above.

3. The chipbreaker matters all the time. I do not know whether Krenov used a chipbreaker. However, he sent me a smoother of his, and the chipbreaker was not set for a shaving. Nevertheless, on edges as well as faces, you want to avoid tearout.

4. The iron needs to be higher than the wedge since you need to hit it. The wedge projects in front of the iron, where it is accessible.

Thanks Derek. And nice website!.

Thanks for the comments. That’s why i was asking here – i see plans and videos of folks glueing the pin. FWW shows rounded, but one flat side, no glue. but i trust LJ more.

last question. is the Hock 3.5” long enough to make it stick out? It seems a 2.5” plane height would make a 3.5” blade @ 45degrees barely long enough.

Hi Mark

Here are two Krenov planes – one is a high angle smoother, and the other a low angle block plane …

This is a cutaway …

I’m not sure how long the Hock blades are, but they were developed specifically for Krenov.
