There comes a time in every

man's life when he outgrows the

basic power tools. When his imagi

nation calls for more.

That's the perfect time for a

router. One of the few power tools

around with hardly any limitation

but your imagination.

Meaning you can make lutes,

beads, reeds, rounded comers,

or almost any other inishing touch

under the sun. Plus a lot of really

practical things, like dovetails for

drawers, dadoes for shelves, rabbets

for joints, etc., etc.

What's more, it's all pos

Not to mention more than 170

. .. referring to cutting the fe male portion of the sliding

dovetail (Winter '76), you say : .. . ..the tapered side is sawed

at an angle, using the saw shoulder as the guide. " Please des

cribe how the shoulder may be used as a guide when it is not

in contact with the work until the cut has been made to its

fu ll depth. It seems that a standard backsaw or dovetail saw

used with a guide block cut to the desired angle and clamped

to the work would serve much better.

Actually, the router plane appears to be the essential tool

to hand-cutting the fe male portion of this joint .

-Stephen B. Ringle, Someville , Ma s.

[Editor's note: Tage Frid replies that because the handle of the saw is beveled

at the correct angle where it meets the blade, you merely eyeball it. When

the saw shoulder looks parallel to the work, the cut will be correct. J

likely to leak r under varying degrees of stress .

However the method of producing the joint is rather in

volved and cumbersome. Several special tools and fi xtures

must be made. Also needed would be a vertical boring

machine or drill press. In the old days a breast drill and a

reliable apprentice were used. The cove and pin were cut fi rst,

with a hollow mill shaped somewhat like a Forstner bit, whose

center retracted into its shaft against a spring. The cutter

fo rmed the cove and pin in one operation .

The spacing is very critical and was achieved with a ratchet

bar, precisely notched to 1/128 in. Ratchet bars were made to

match each size mill. Next the pinholes were drilled (using

brad point drills) in the end plates or drawer sides, and these

matched the pins previously fo rmed by the mill, because the

same ratchet bar was used. The scriber is set down over a pin

and set to the radius of the cove. Remove its bushing and

replace it with the correct size scriber pin , and scribe an arc

directly above each pin . The scriber must be set so that the

scallops are ju st an interference it when the joint is assem

bled . A ine saw cut is made down to the interstice of each

arc . Next , a sharp half-round firmer gouge of a radius to

match the cove is itted with a pilot device equipped with a

pin to match the pinhole.

The end plate is clamped down over a piece of hardwood

(maple) that has a dado cut down its length, that fa lls directly

below the pinholes to accept the guide pin . The guide pin is

slipped into the pinhole, and the chisel is adjusted to fit

between the sawn lines. Strike the chisel in the normal man-

Regarding the article by Bob Stocksdale (Fall '76), I am in

no position to quarrel with a professional wood turner whose

work is as fi ne as those pictured ...What I don 't understand

is his sanding sequence. Starting with 16 grit seems incredible

to me-I myself start with 50 grit and fe el that much of the

time this is too coarse ...Ideally it seems to me no sanding

other than a very fine grit should be required .

-Alex R. Ross, Stzlwater, Okla .

Regarding Clarence Hill's question about an old drawer

joint (Winter '76): During my days as a master pipe organ

builder, we called this a pinned cove joint . As to its origins, it

could have been either German , French or English. A larger

version than that normally seen on drawers was used on wind

supply house. This is probably the easiest steel with which to

work , thereby making it a cinch for the amateur ... Concern

ing the quenching oil, you should have a minimum of one

gallon in a pan shaped like a bread baking pan. This allows

ample oil to absorb the heat of several hardening attempts.

Also, never use cold oil. It should be preheated to a warm

temperature with a heated scrap of metal.

-R. Pey Mercu rio, Kin giel, Main e

Gordon Harrison 's article on heat treating (Fall'76) did not

define the rwo common types of carbon tool steel. The two

types we should be concerned with are the water-hardening

steels and oil-hardening steels. It is quite easy to distinguish

berween them by a spark test on a grinding wheel.

Water-hardening steel will give off a shower of " Fourth of

July" type of white sparkly sparks while oil-hardening steels

give of a lesser amount of streamers, red in color and fewer

dead-looking sparks at the ends of the streamers .

If you attempt to harden oil-hardening steel in brine or

water you are quite likely to damage the structure of the steel

and in many cases there will be shock cracks large enough to

destroy the tool. If, on the other hand, you quench many of

the water-hardening types in oil , you may get no hardness at

all or at best only a hardened skin on the thin sections of the

tool . Usually tles, springs , etc. are varieties of water-harden

ing steel and in general do not make a very good cutting tool

because these steels are alloyed with small amounts of other

materials to enhance their ability to do the best job for which

they were intended. Oil-hardening or type 0-1 steel will give

you that silky, velvet-smooth cutting edge desired by all

Sure hope the man in the photos in " Heat Treating" (Fall

'76) is n't a teacher. His safety habits leave much to be de

sired : no gloves to protect fr om the heat , loose sleeves and

shirttails , no safety glasses for pops and spatters.

-David Rose, To kyo, }apan

Your article on heat treating (Fall '76) was a very informa

tive item for the woodworker as it helps to remove some of the

mystery from the steels that we all use.

When you soften steels you definitely anneal them, but

there are a variety of procedures to utilize, to gain given prop

erties . In the metalworking industries annealing means that

after you have heated the steel past its critical temperature ,

you then slow-cool it in still air-in the furnace. This gives

you soft steel with a fairly coarse grain structure. If you were

to take this same piece of plain carbon or low-alloy steel and
