INTRODUCTION

Your Craftsman Router Crafter is a newly developed machine which wilt enable you to utilize your router to its fullest--making table legs, turnings, posts, spindles and other turned carvings of almost any design you wish. There are four basic operations

which carl be done on your Router Crafter. They are:

1. Straight "beads and flutes" cut lengthwise (paral- lef to the work piece). These may be of a straight

or tapered style.

2. "Roping" or "Spiraling" _ both right and left hand -- and may be either straight or tapered.

3. Turn "beads, coves and steps" around the work piece. The different forms are made by the shape

of the router bit which is used°

4. Contour turning of varied shapes by letting the router follow a template which is attached to the

front of the Router' Crafter..

The four basic type cuts enable you to produce hundreds of different designs by using them in

combination.

Included with this manual are drawings of typical full

size turnings. (Inserted in back cover) When read- ing any of the sections on the various types of turning,

check the sample being referred to as this wilt help to understand the many turning methods and designs which are possible with the Router Crafter..

CONSTRUCTION Baslca_ty the Router Crafter is composed of a Head

Stock and a Tail Stock (Fig. 20) which are held in line with each other by four heavy steel tubes (Nor 44 &

52). A carriage (#33) which carries the router is mounted to and travels along these tubes_

The head stock consists of a cast aluminum frame (#6), a cable drum (#20), on which the steel cable

(#42) is wound and which turns inside the head stock frame, a cast aluminum drive spindle (#18) which turns

inside the cable drum, a locking plate (#9) which will lock the cable drum relative to the frame, and an index

pin (#!7) which permits the indexing of the drive spindle (#18) relative to the cable drum (#20)° The drive spindle can be indexed in-increments of 15°-

that is the indexing provides for equal spacing of 2,

3, 4, 6, 8, 12, and 24 cuts around of a work piece.

A crank (#1) which fits into the back of the drive spindle is provided to rotate the work piece, You may

notice that the drive spindle (#18) has considerable

"play" or looseness in the cable drum (#20),_ This is

normal and is no cause for concern_

The tail stock (#47) is also an aluminum casting which carries the tail stock center screw (#50) which is a

1/2" threaded steel rod° The center screw passes

through a guide bushing (#49) which is adjustable up

and down to permit turning straight or tapered work pieces,. The tail stock can be positioned anywhere along the steel tubes to accommodate different lengths of work pieces,.

The vinyl coated steel cable (#42) which is wound around the cable drum runs over Deirin® pulleys (#12

& 15) and is joined together with a tension spring (#41) which serves to keep the cable taut. There are

two metal lugs which are attached to the cable- one on the upper and one on the lower cable lines° The

lugs are for affixing the cable to the cable clamp (#29)

to advance the router and router carriage when making

"roping" or "spi;aling" cuts. Attaching the upper cable lug to the cable clamp produces a left hand spiral whereas attaching the lower lug to the cable clam'p

produces a right hand spiral. The lugs are left un- attached when making other than spiral cuts..

The carriage (#33) has two identical screws (#36). These are used to adjust the depth of cut and also to

provide a repeatable "stop" or maximum depth gage_. There are two hose type clamps on the top tube (#14)

which serve as stops for the carriage at each end of the desired cutting travel. The two clamps can be positioned against each side of the carriage to prevent any lengthwise movement of the carriage. Clamps, screws, nuts and washers 'A' are provided _or mounting the Router Crafter on a base or bench. See

Fig, 2, The mounting box 'B' could be made from 1/2

to 3/4 inch wood (plywood works weII)_ Mounting

Router Crafter as shown gives a place to store toofs, bits, etc.

BEFOR'E SE'i_TINGUP A WORK PIECE in the Router .....

Crafter, do the following: 1o Refer to Fig. 3. Hold the cap screw "B" in place

with the hexagon wrench which is provided and tighten the wing nut "A".. This clamps the plate

"C" against the cable drum and locks the cable drum so that it can not rotate. (The wing nut wilt feel a little hard to turn becauseitis a vibration

resistant nut so that _it will not come.loose during.

router operation)..' ......... " ._"

2,, R_fer'to Fig: 4,: Pull= out knob "A" and rotate the

knob so that the '_wings" on the indeX'pin just in front 5_ the knob are resting in the shallow groove or "detent_'at "B',. This holds the index pin and knob back and disengages the .cable drum "C" from the drive spindle "D", and thus will permit the drive spindle "D":to rotateand the cable drum to remain stationary _ clamped to the..head stock

frame.

3. The top two tubes should be waxed with a hard drying paste wax such as Sears No 28 6953 Auto Paste Wax. This wilt give a smoother sliding action when the router carriage (Fig., 5) is moved length- wise in the Router Crafter. Do not use oil or grease,

because they are,too tacky and will _gum up the bearings in the router carriage.

DONOT !!FORCE" ANYTHING TO TURN° For example;

if the cable drum is clamped to the head stock frame

and the index pin is engaged to the drive spindle, DO

NOT try to turn the drive spindle as this would damage

your Router Crafter°

WOOD PREPARATION Sometimes it is difficult to obtain thick wood for

making table legs, posts and so forth, but this isn't necessary. If you have thin boards such as 3/4" or 1rt

that are smooth, you can put 2, 3, or4 thickness to- gether at one time using Craftsman white glue and

ordinary "C" clamps_ Rip the boards to about 1/4"

wider than you plan to have final thicknes of the square post..This allows er!oughextra stock to trim the edges square and smooth after the boards have been

glued together_ The wood piece, of course, should be squared and cut

to length° No further preparation is needed on the end that is to go into the head stock° The tail stock end

must be center drilled; that is, a small chamfered hole must be put in the center of the end to receive the tail

stock center. You may use a standard center' drill. If

a center drill is not available, drill a 1/16" or 3/32" hole about 1/4" deep and then counter sink the hole

to about 1/4" diameter_ See Fig. 6. The center hole should be lubricated with wax, petroleum jelly, or

some other grease lubricant° DO NOT GREASE ANY

OTHER AREA.

MOUNTING THE WORK PIECE IN THE ROUTER CRAFTER

The center' bushing "B" should be set at the lowest

graduation mark "C" on the tail stock "D" (Fig. 19). The tail stock frame can be positioned anywhere along

the tubes as desired _ close to the head stock for short work, far away from the head stock for longer

work. Generally, if routing is to be done all the way to the tail stock end of the work piece, the pointed end

of the tail stock center should extend past the tail stock frame about 3 3/4"_ See Fig° 7. Loosen the 4

screws ("D") with the hexagon wrench which is pro- vided. Place the plain square end of the work piece

in to the drive spindle with the corners of the work between ribs as shown in Fig, 8_The end of the work

piece with the center drilled (chamfered) hole should point toward the tail stock. While holding the work piece in the drive spindle, position the tail stock

frame so that it is about 3 3/4" from the end of the work piece. Remove the work piece_ Using a tri-square,

combination square, or triangle (30°-60 _ or 45°), square

the tail stock with the steel bars as shown in Fig 7. Holding the square in position, tighten the four screws

"D" just snugly, tightening the top two screws first, DO NOT OVER-TIGHTEN. NOTE: THE TAiL STOCK

SHOULD BE SQUARED EVERY TIME iT IS MOVED

(This does not apply when only the center screw is adjusted). While holding the work piece against the drive spindle, and with the small hexagon nut "B" seated flat against the tail stock frame, turn the knurled end of the tail stock center "A" until the pointed
