WEDGES

Splitting wedges are typically

steel, but can be made from

aluminum, wood, or even hard

plastic. They are readily available

at hardware stores, tool compa-

nies, yard sales or antique stores.

These wedges are used to split a

log in half (from its end) along

the line scored by a froe, or to

score the line in the absence of a

froe, and can also be placed in a

lengthwise split and struck to help

things along.

BEVEL ANGLES

Some of the cheaper steel versions

are cheap for a reason, and

frequently don’t perform well. It’s

common for production-made

wedges to have short, steep bevels

that cause the wedge to pop right

off the wood when you strike it.

These bevels need to be reground

into more gradual, long bevels.

Regrind until the bevels are

blended smoothly into the body

of the wedge and the wedge wants

to bite into the wood when you

strike it. As with most things,

balance is key. A taper too thin

could compromise its strength

and pose a safety hazard. See

the illustration on p. 101 in the

Preparing Bowl Blanks chapter.

REPAIR DAMAGED EDGES

If used with a sledgehammer,

and after prolonged use, steel

wedges may mushroom, bringing

steel over the top edges. (A)

This mushrooming can present

a significant safety hazard if

shards from the damaged areas

come flying off after being struck,

essentially becoming shrapnel.

They should be regularly ground

or filed down to prevent this. It

sounds ridiculous that such a

small thing could cause damage,

but it happens, and the stories

aren’t good. A maul used with steel

wedges will prevent mushrooming,
