Pocket Froe

Post by charangohabsburg » Sat May 04, 2013 2:55 am

A pocket froe. Well, it depends on the size of one's pocket, of course. I also could call it "desktop froe", but this would not be very descriptive as just about any desktop is big enough in order you can put a froe on it...

So, this is my brand new pocket froe, just about the size needed for splitting bracewood.:

The following photos depict some stages of the manufacturing process.
Maybe you remember this one - my tool steel supply I got about two years ago:

Image

This time I picked an old, blunt and dirty file out of the tool steel pile:

Image

Getting held agains my grinder the file lost its teeth, and with some coarse sharpening stones and a bit of patience I got the blade reasonable even, flat and sharp:

Image

The I cut off a piece of 20x4mm flat iron and made a square, according to the file tang conical hole in it:

... and tapped this lever on to the tang:

Image .

Then I brazed the two pieces to not come lose when in use, and mounted the original handle after having filled the worn out hole with a dowel, and after pre-drilling a new hole for the tang:

Image

Normally, pushing the lever with the thumb is enough to wiggle the pocket froe though the readily splitting wood. Like this:

That's all. Thanks for looking.

Like that, it's always good to recycle old files 8) .

Thanks for the tip, I might stock up on old files when I go to the local market, there is a guy there every weekend with a truck full of old tools.

Cheers

I think that I already have one of these on my Swiss Army Knife. :)

You come through with the goods again Markus, is it Swiss Spruce you are splitting?

I like it , a very neat job there .
My version is a heavy blade japanese bone cleaver , mighty effective . Not so elegant .
The froe doesn't lie , soon weeds out timber with run off . A handy trick i've been shown is to always spilt the billet into halves , getting progressively smaller , it saves getting splits that jump across the fibres .
By the way if anyones interested there's a froe on ebay right now , I think they called it a large shingle splitters axe , a froe it is .

Thanks everybody for your comments!

@ Eric and Col: it is a good idea (at least for me) to always have some tool steel around, just in case of the need of some kind of new, maybe special blade. For me, old files and sawblades are the best and easiest resources, I am not thinking much in recycling when using them. Although, of course recycling is always a good thing. 8)

Of course, there is no tool you can not find on the Swiss Army Knife. It even sports a thickness sander (if you have the patience and skills :twisted: :mrgreen: ).

Thank you Steve, and no, it is not spruce (but almost). What you see comes from this stem, which is Silver Fir (Abies alba) from the woods in the neighbourhood (a 500 meter walk away):

Image

Silver Fir seems to have about the same stiffness to weight ratio as Spruce and, unlike the latter one has (almost) no resin pockets at all which makes it a highly appreciated construction lumber here around.

Before making this "pocket froe" I also thought of some heavy knife like your bone cleaver, but then I just started to like the control this lever gives you when splitting the wood. I have a big and heavy froe (34 cm blade, 2 kg) which I use to split log halves into smaller pieces (for entire logs I prefer wedges). Using that froe I came to the conclusion that I would not like it very much handling that kind of weight on my "desktop" (= bench top, of course).

Too true!

It is really amazing what one can find within one tree stem.
Here, still the Silver Fir from above, I got a slight but still rather acceptable twist:

Image

One meter further down the stem things got really wild, from just about the same twist as above in one half, to this:

:shock:
Splitting such interlaced/wavy grained wood with a froe is close to impossible and it is better to use wedges, or a saw if one wants to make something else than firewood.

Sometimes there are very notable differences even within the same length and within the same quarter!

Yeah, shingles... Have a look at this man, how he produces some of the nicest Western Red Ceder guitar tops - for roofing his house! :shock: :dru

Markus, 500 metres, that is so cruel I mean cool. The felled logs looks pretty damned straight and not much in the way of any significant limbs..reminds me a little of Port Orford Cedar (Cypress Pine) is there maybe a top or two in that trunk?

Yes Steve, there were "a top or two" in that trunk! :lol:

But as I have pointed out before, not all lengths were so nice, I mean that sometimes the grain would only be straight in one direction or had a severe twist which would have resulted in a twist in the range of 1:15 runout or worse. I had ended up resawing only three lengths, the rest is rotting away now and getting eaten up by the bugs - they especially love the sapwood ;). Last week I was splitting the 8 quarters of some other two lengths to get some bracewood, but two of the 8 quarters are only good for firewood (see the picture above with the interwoven grain).

Don't know about the twist being only good for firewood Markus. So artfully imaged I think there's a market for poster sized photos. I'd happily have that one the wall :D

Hi Kevin. Yes, of course there is always a market for great photographs but I'm afraid (no, I'm sure) that the ones you see above don't qualify. However, if you like them feel free to download here their full resolution versions and print them, or get them reproduced at your preferred size ;).

Maybe I should sell the wood itself at an exorbitant price, saying it was something special. I reckon this would make one nice blister figured and dull sounding (or alternatively: collapsing) guitar top - or one could hang the wood as piece of modern art on the wall. :lol:

Cheers

If you really want to mount it on the wall and call it "modern art" then you will need a critical discourse to got with it or it will just be a piece of wood on the wall, if you need help with that I would be glad to help.

Deliberately choosing a top that will collapse ? - Now that is starting to sound like so many other examples in modern design and manufacture that have components with built in obsolescence :twisted:
I'd stick to the modern art idea (accompanied by a critical discourse from Jim of course) :lol:

Thank you Jim and Kevin. It seems we have now at least two excellent viable marketing options for firewood! :lol:
