Double Bit Axe Shape Variations

Heh heh...
Why a double bit for splitting, though? Am I missing out on some common knowledge here?
I think I'd go for an old splitting maul.

 

Sounds like you're looking at a Puget Sound Falling pattern axe. Those are designed for the specific purpose of felling large softwood trees in conjunction with a crosscut saw.

For general woods use - clearing trails, etc. - a western pattern DB is a good choice. Most DB's in the 4-pound range will make nice splitters using the twist method.

 

I like a heavy single bit for splitting duties, 4-6 pounds, with a nice high centerline. When that isn't enough I'll usually reach for a sledge & wedges. There's very little that a 5 pound axe won't split that a maul will. Still, I like mauls. I like the feel of that powerful hit. I just don't find much wood that splits best with a maul.

 

Them Puget sound patterns have long bits to reach deep into a notch off a spring board. I see them with handles over 36" pretty regular. I own a couple in that pattern but have not played with them yet. I would be interested to know how well they would split useing the twist method. They may perform great. Let us know what you learn.:thumbup:

 

I've never used a DB for splitting, and a Puget Sound head was typically hafted on a 42-48" handle. The long profile increases head wobble and requires skill to swing accurately. Save that 36" handle for a quality True Temper. I'm fond of the Michigan pattern, but then I'm from Michigan…….

I split my wood -- mostly red oak-- with a monster maul, which busts up the rounds pretty fast.

 

I split a lot of green maple and elm, (as well as some random chestnut, mulberry, cherry, and others) and I've found that what my 4# single-bit won't split my 8.5# maul usually will, but if anything survives both I just save it for when I rent a log splitter at the end of the season. (I split 4-6 cord of wood a year, so I can't afford to rent it for the whole pile). I've never split with a double-bit, mainly because if the difficulty of getting it un-stuck.

It's good to have a few tools available for spitting. I personally like to have a double bit at hand for straight grained wood. They are my favorite splitting tools because you can sink it into a split half laying on the ground and pick it up without being over. I like an 8 lb maul for the tougher pieces w/o straight grain or with knots. A wedge and double jack are great for the really tough pieces.

All are pretty easy to come by and if kept nearby are easy to grab depending on your need. A good splitting block also helps reduce the amount of energy you use. You bend over less and it's safer plus it adds some weight behind the piece you are splitting.

I' sure you know a lt f this stuff but it also might help people with less experience splitting.

Weight.

Grab a 5 or 6 pound Dayton from Council. Or maybe try one of Helkos 6 pound axes.

Wouldn't a maul be the best dedicated splitting Axe? I've generally only ever split hardwoods, so I prefer sledge (I used to like 16 lbs., but now I'm more comfortable with 10) and wedge(s)--never found anything that wouldn't split, even pretty monstrous trunks. As a kid (not small at 200 plus pounds, though) I played with mauls at my friends house, but his dad bought most of his firewood in fairly small sizes. Even at that we had to use the wedges pretty often. I'm guessing soft woods where that is the thing would be a lot easier to split. Even some softer straighter hardwoods, also, but I would want at least a maul.

I have a great old TT Woodslasher double bit michigan that is hard to beat for felling, but it makes me more than a little nervous for splitting. Too much chance it could bounce back and split my head. Don't get yourself hurt trying to be unique!

Anyway, I guess my point is that very few people consider a db Axe an ideal splitting tool, so the chances of finding one that is good for that might be rather slim...

 

I haven't found a maul that will cleave through knots efficiently. Until then I'll stick with an axe.

 

Working on a 4.5# Norlund Rafting currently- hope to have it done this weekend while I'm home. I'll have to see if I agree with you!

 

Square peg,
That is a good point! I guess I would say sledge/wedge until the last split or two, then a heavy sb Axe. I meant to convey that i was never that impressed with the mauls, but that they must work for someone. I remember me and my old pap splitting 4+ ft dimeter rounds of oak (one fell on our chicken house!) with a sledge hammer and a couple of wedges which is all we had (I've got 6 or 8 now, and I don't even burn firewood in the house now), whereas even 16" rounds could be irksome with the mauls... We usually had a boys Axe or 4 lb. Pole Axe to clean up. A block is indispensable for any splitting, although I see people doing without.

What would you say is the cutoff point b/t wedges and Axe? I am rather plodding in my pace, so I will switch to wedges around 8" thick. It seems like there is very little time lost with wedges on the bigger stuff overall.

 

I've never used a maul or wedge (but I do own a maul now waiting to be tried), but I used axes exclusively for splitting wood for the family a few years back. Most were old, dull, and had bad hafts, but I still got through it all pretty easily, even with the occasional knotted monster. So because I am biased, I still really like an axe fro splitting. Grab something in the heavier weights with a high centerline and it'll split well, at least in my experience. My 85+ year-old Kelly Michigan pattern SB splits wood really, really well even at a relatively lighter 3.5 pounds. I think it's due to the sharpness I gave it and the high centerline and awesome geometry the maker gave it.

 

Those are the key things, aren't they? Geometry makes the splitting axe. Thin-cheeked euro imports need not apply.

For me it's whatever works. I'll start with the axe. If I can work a large piece down by taking chunks off the edges I'll just stay with the axe. If the axe ain't getting it done I'll usually go straight to the sledge and wedges. Once in a while I find something which the axe just barely won't split. Then I'll grab a maul.

A couple years ago I got into some London Plane - toughest stuff I ever split. Coarse intertwined grain. Much tougher than even Elm. It laughed at my maul. The larger rounds soundly rejected my wedges. That's when I learned a trick. Put a very slightly hollow ground bevel on the tip of the wedge and it will stay stuck. Then nothing made of wood will stop it. Mostly I use a single jack with wedges. A stubborn piece draws a double jack.


Only you know how your wood splits - what's working and what's wasting time.

 

That was really the key to the Puget Sound falling pattern. Long bits and deep penetration for springboard notches.

Back in the day of crosscut saws and axes most trees were never felled with a cut close to ground level. These were all large old growth trees. Frequently, more often than knot, they began life atop a nursery log or nursery stump. This resulted in big fat "bell end" trunks that were rotten in the middle and had no value as lumber. Considering the human effort that went into falling and bucking such a tree, no effort was wasted cutting wood that woudn't go to the mill. So the springboard was invented to get the sawyer up above the bell end and into wood that was profitable.

And to set a springboard you needed a deep notch. Sometimes a sawyer worked on a single springboard. Other times a pair of springboards were used as the base for a makeshift scaffold from which the sawyer/axeman could gain access to a large cross section of the old growth tree.

A few years ago I was fortunate to find a bunch of perfectly preserved springboard notches. In 2012 and 2014 the Elwah Dam and Glines Canyon Dam were removed from the lower Elwah River, built in 1913 and 1927 respectively. In 2014 I hiked the Glines Canyon and observed springboard notches that had been preserved at the bottom of the Glines Canyon Dam reservoir for 87 years and just revealed a couple months prior.


They appeared fresh, as though they had just been cut. It was startling how wide and deep these notches were. A special axe was needed to form them, a long bitted axe, the Puget Sound falling axe.


This notch is almost 12" wide and 8" deep. My Leatherman is open 8" wide for scale.


In some notches every blow of the axe was plainly visible even after 87 years!


After some time of looking at these photos and considering their significance it became apparent to me why and how the Puget Sound falling axe evolved. The long bit was necessary to cut the springboard notch. And the long handles, 36" minimum, gave the sawyer/axeman access to the full width of the trunk of these old growth trees.

 

Guys I'll be splitting some wood here in a couple months and I have a 4 pound Kelly, an oversized aingle and a Puget, if you can wait that long I can test all 3, only on oak and hickory though so I feel one is gonna pull ahead more than the others
