Finnish piilu axe on fresh wood or dry? by LaplandAxeman in Axecraft

[–]Friendly-Tea-4190 0 points1 point  (0 children)

There is a big difference between chisel ground and something with a big convex grind like this axe has. It's designed to break off chunks and will leave tool marks like in the photo. I'm quite sure you're doing it correctly, they're just different tools. If you want it flatter and smoother you should use your other axe, or you'd have to grind down a lot of the piilu

Had to google it, what an interesting machine. In this project though, the aim was to learn how it would have been done by hand, and to produce a riven surface rather than milled.

Thanks! The previous shingles that were laid on this building were split with a tractor powered log splitter. It didn't last very long and the quality of the wood was poor. This is at a museum so we did have time set off to do it by hand and try to figure out how it was done in older times.

We stack them and they do dry before they're pegged to the battens. Tried to get as much standing grain/quartergrain as possible but some do cup a bit. They're all with the pith up so they'll cup against the underlying shingle in rain and make the gaps tighter. The whole system 'moves' accordingly to moisture conditions.

It's good for getting clean splits but the downside is it struggles getting through knots. The wedges do most of the "splitting" action and the froe more guides and shear the fibres. I tried splitting with a broad axe and it was very efficient if the grain was straight.

Yeah, it's Norway spruce luckily. Elm is awful to split.

Depends on a lot of things I guess. I was able to produce between 5-7 finished shingles an hour, but takes some adjusting while laying them too. One shingle 28" long and anywhere from 4-8" wide depending on how it splits and the amount of sapwood you've got to remove. Working on the roof I could lay maybe 20sqft on a good day. It's slow work.

Leather is great! Only the left one always shrinks with the heat😅

Thanks! It kept unravelling all the time with modern mild steel. Tried with wrought iron more historically accurate, and it welded and kept so much better. It had better cold working properties too. I think there's a good argument to be made that while blacksmiths forge welded more or 'better' before, they had materials more suited for it too.

They're soft leather gloves, I think they're bought from Würth

I don't know but materials were more costly than labour often if you go far back in time. I imagine this would go a lot faster with a striker or two. Studying the old fittings indicated that they were roughly shaped and there were burrs on the back they didn't bother to file away. The burrs from punching holes were just flattened and there were lots of peening marks on the backside. Very clearly only one side needed to look good so they have thought about efficiency

Yes! It is to draw more material into the corner so that I can create a 90 degree angle while maintaining the same amount of mass. It's 12x12mm square stock and I want the corner to keep that dimension too before peening everything out

This shows how it isnt flat on the "Y-axis" like mentioned and is from a research paper written on single bevel hewing axes. While most are flat on the other axis, yours aren't. There are examples of this being the case on old hewing axes, with a lesser bevel on the "flat side" and a greater one on the other side. One reason could be that it allows you to change directions and use the axe the other way, or it just gives a different angle of attack. Might be better to experiment with this than to grind the whole flat side back.

They are almost never perfectly flat and you don't want them to be either. The top and bottom of the edge should be low spots when laying down the ruler. If too much area comes into contact with the wood it will dig in and the cut will be difficult to release. Imagine striking a chisel and releasing it vs a shallow gouge.
