Krenov Style Jack Plane
 
Ok so its not a pretty as Sparky's plane because I had to use what I had.

I had a nice and very hard piece of African Mahogany for the body, the wedge and pin are wenge, and the sole (glued to the center before the sides were attached) is Jatoba.

The plane is about 17" long and utilizes a 2" hock blade and chip breaker set at 55 deg.

The pin was set at about 1 5/8" up from the bottom. Its a bit higher than I would like but I had to set it that high for finger clearance when clearing chips.

I only have a 1" blade for my bandsaw explaining the jagged cuts, got a little shaping to do. :D

Close up of the mouth. It looks a bit larger than it should but thats only because the blade is retracted a bit. The opening with the blade set for a nice shaving is probably about .005"

That's a big one!

Looks like your next purchase will be a spokeshave.

Nice one, Eiji. I'll look forward to seeing it finished (you are going to finish it, aren't you?). As for spokeshaves, you should seriously consider the Lee Valley set. They're really sweet, feel great in the hand, and work like a charm.

I forgot to ask....how do you make the round tenons?

Re: Krenov Style Jack Plane
 
The pins are 9/16" square to start. The length is just shy of the plane finish width. I cut 1/16" deed cheeks on the table saw and then dadoed a board to be able to hold the pin vertical on the drill press. The square pin is held upright in the dadoed board and a plug cutter is used to cut the tenon. Clean up the cheeks with a sharp chisel and shape the pin to the desired shape leaving one side untouched. When drilling the tenon I made sure that the same side of the pin was facing the fence on each cut.

It's in the book Michael!Drill Sergeant

I think the book is a good start but dont believe in following others step to the T. I used it more of a starting point, considered the experience of the author, looked at the woods he uses and made some changes to suit the work I do.

We'll see how that works out.:D

I think I will be making alot more of these in the future.

If only there was a tool that could hold the square stock and spin it so that you could hold, say, a chisel against it while it was spinning, and make part of it round.

Still, in the absence of a lathe, your technique worked pretty well, Eiji. :thumbsup2:

I don't think that a lathe is the right thing for this, might be a bit too much flex to turn those little tenons I think the technique in the book is the right, and probably simpler, way to go

Jay

Yeah, I'm reading it as well, but there are a few projects ahead of it in the queue.

This is a good point to mention the title of the book, and maybe post a link to it Poking
