BLACKSMITH ’ S JOURNAL ARCHIVE

This month we cover a carpenters one-piece chisel.

CARPENTERS CHISEL

This chisel is made with traditional materials (wrought iron & high carbon steel), and traditional techniques.

Wrought iron is the premium material for blacksmiths, and the piece used here is highly refined bridge iron.

The Blacksmith’s Journal Smithin Magician is a helpful tool for this project, especially if you’re working alone.

Dies used include cut-off, side set, fuller, offset fuller, and sizing.

If you’ve never forged wrought iron before, it’s worth the effort to find some and forge it into the required size

by folding and welding if necessary (the process will actually further refine the iron). Wrought iron should be

worked at high temperatures, and never below a red heat. It welds very easily when heated white hot, and

doesn’t scale and burn as much as carbon steel.

BEGIN WITH 7 / 8 ” ROUND

STOCK AND FORGE IT

FLAT ON TWO SIDES

UNTIL IT IS 3 / 4 ” THICK.

CARPENTERS CHISEL

NOT TO SCALE

3004 #229 FEBRUARY 2010

MARK THE FLAT PORTION

OF THE STOCK WITH A

CHISEL ABOUT 1” FROM THE

END. YOU WILL BE ABLE TO

FEEL WHEN THE SMITHIN’

MAGICIAN SIDE SET DIE

DROPS INTO THE NOTCH

WHEN THE IRON IS HOT.

LOCATE THE MARK AND

STRIKE FORCEFULLY TO

EMBED THE DIES. PULL BACK

SLIGHTLY ON THE STOCK

ONCE THE DIES ARE SEATED

AND CONTINUE STRIKING

(THIS WILL PREVENT THE DIE

FROM JUMPING TO A NEW

LOCATION AND MAKING

UNWANTED IMPRESSIONS).

PUSH INTO THE DIES WHEN

MAKING THE SECOND

IMPRESSION.

THE SIDE SET MAKES

OPPOSING SQUARE

SHOULDERS. BE SURE

NOT TO DRIVE THE DIES

TOO DEEP. EXTRA STOCK

IS NEEDED TO DRAW

DOWN TO FINAL THICK-

NESS.
