attachments can be supplied. Similarly,

although most'machines are supplied equipped to cut

1" pitch

Furni ture dovetails, many other equipmen,ts are available for other styles and pitch sizes.

In all cases, the general method of operation, the working adjustments and the controls are the same. The following notes,

therefore, refer f.irst to' the detail of operation tha·t is

common to all machines; the variations are dealt with in subsequent pa,-agraphs , a s are the differences betl<een manual and

pneumatic cramps, etc.,

Inf'ormation is given on lubrication and cleaning. In cases

where the machine has been dissembled to facilitate export

packing, notes on: r.e-assembly are given in Appendix

'A'.

IMPORTANT:

The slides are usually locked by tightening the gib screv.s to prevent movement during transit.

Re-adjust these screws before operating.

GENEi~A.L

PRINCIPLE OF OPEi'LATION

The cutt.ers are accoIlll11odated in a bank. of' spindles (25 or

17). The cutter spindles all rotate in the same direction.

The table, carrying the cramp bridge, is fed on to the cutters under" the 'influence of a cam drum. By using'different cams different t'able actions are possible to cut different'dovetail styles and'clifferent pitch sizes within' the style. Having selected the appropriate style and pitch, adjustments in the

machine enable variatiops in the dimensions of the dovetailing.

. The adjustment for the length of pin "c", i.e .. the amount the cutter h~ad extends above the table level, is by the two

Screws F.F. The frame carrying the cutter' spindles is cramped in position by Screws G.G. I t is suspended on' Screws F.F. To adjus t, reI e2.se Screws G. G. and turn Screws F.F. clockwise to

The dovetailing of Rebated Fronts is similar to the normal flush f'i t typ" exoept that th" Stroke Adjustment (Scre,; E) will be placed to give +onger stroke than is norm2.11y required f'or the thickness of drawer sides. The ndditional length is necessary to spAn the depth of the rebate~

The Depth adjustment must be mov~d towards DEEP, as in effect a very doep cut is necessary in the drawer front. Having made this (1djustment i t is advisable to check the cam cycle by using the hand crank to ensure that the cutters do not foul the finger plate,

In cases where the cu-t;.ting of the rebate is not regularly accurate i t is avisable to employ a special finger plate with projections against which the shoulder of the rebate will locate.

This plate can be specially supplied! or the standard plate can be drilled to accept smRll dowel pins.

SECRET DOVETAILING

S·ecret ·dovetailing is achieved by cutting the whole of the furni ture dove/tailing action into each piece of wood. To do th;:is the tl.,ro components of the joint are placed in the machine side by.side. The horizont8.1 wood does not butt "UP behind the vG.I"'tic<:'I.l piece, but is ple.ced along side. with the outer edge aligned with the "outer face of the vertical "piece.

Jdhen producing i t is probably advisable to cut all the verticRl piEces Cl·t onG operation, and the horizontal at another.

CRAl-IPS & "ORK FENCES

A

full sat of work location fences is prov1ded. There are two pairs of fences on both the vertical face of the and on th.e horizontCll face of the wo·rl<:. table.

These

2..150 carry rule. scales to assist in po si tioning the cramp bridge two faces fences.

I t will be observed that thb~e rule scales are zerobd on the centre line of the machine. I t is necessary to work outwards from the ccntr~ l~ne to keep the work correctly I'handed". For

GXRmple ono pair of the table, br horizontal, fences arc usually placod on the 12!! mark, one each side of the work table.

A

drawer front, wh&n being dovGtailGd will be offered up with the rac~ odge to the right.hand fence, and the::n i t will be flhanded!'

OV2r and offered to the left hand fence. hs alrearly ind~catGd·, i t is usunl to keep onc pa~r of fences www.DaltonsWadkin.com

This c-l1ables any width of board l"!.P to 1211 to be worked· without altering the fence positions except for very minor adjustments. Should the boards be les~ than 6!1 wide the remaining fences are placed, b~ck to back, dovot~iled

·o:q

thE: centre lino, ·when four joints at each table op~ration. eRn

For widths over

6" be but less ihan 8

11

, the centre .fences should be spread to approximately the 4" marks, when three joints can be dovetailed togother.



The precise setting of' Cl fence depends upon the €:JX:1ct \.,idth

of the work to be dovetailed and the exact cbAracteristic

raql1ircd of the final joint .

.

Much

will depend upon the user's requirements and decisions will come morG 8nsily ?s experience: is gainGd in using the machine. The general rule, however, is

th"It the table, or horizontal, fence is placed on the full pi tch

dimension and the vertical, or bridge fence, half a pitch from

'this. Fcr example on the

1" pitch dovetailing, «hich is the most commonly used, the table fence « i l l be placed, with the

edge ngHinst \..;hich the wood will locate! on the full inch mark, say 12". The bridge fenco \-1i11 then be ,played on 1.1:tn or 12t" j that is half.a pitch

of'f~

This will cause the two edges to align

:"hen the joint is knocked togeth8r. Moreover, the table fence

being on the full j.nch m8rk 't-.rill cause the edge of the

\<lood Lo fp.ll plumb along the brass supporting

fing,~r

Rnd remdin

so~id wood. I f this rule is not followed th6 upper or lo«er ~orner

of

R jOint, or both, will have half a dovetail pin showing.

1Vh~n working pit.ches other than 1" the same rule "pplies except that the table fence positions become multiples of the

pitch (the f'ull

inch

marks were multiples of' 2 ft

) .

In any

case

"im to keep the edge of the wood th"t m2tters most, usually the

upper edge of a drawer

fron~,

to fall plumb along the centre of

the fingc.,r.

To 2ssist in keeping the vertic0.1 waods up to the fencE:s prior to crahlping, spriI,1g fences are provided. These should bG plnced -to give light pressure on the edge of' the ,,.rood to hold it against the ferice. They have no function af1;er cT2:mping, and

when the width of' the «oods absorb the full ,"idth of the bridge

face they h8ve to be dispensed with.

1Vhen cutting very 'vide stock up to the full capacity of the ma6hi~e,

PNEmLWIC C",AMP BRIDGE

The Pneuma tic Cralilp Bridge has two bF.\.nks, of eight cramps each, oper~ting in the vertical and horizontal directions.

The cramps are closed by foot pedals and are releasGd automatically.

This is dealt 'i.,ith in

Cl lcter parngraph on. Pneumatic type machines.

Each cramp has an independent air stop valve so that i t can be put out of action to conserve air ,.;hen possible! \fuen Cl cramp is in use the stop valve should be well open, three complete turns of the screw.

The cramps holding the horizontetl ·weods require no adjustment. The trav.c:l is ample to take up varietions in the thi ckness of

wood.

The cramps holding the vertical wood, ho,,,evl..';r

I must be adjusted to suit variations in thickness not so much to facilitate cramping as to prevent woods being incorrectly positioned. The yoke carrying these·cramps is adjustable as

Cl unit by screws at each end of the bridge. The yoke should be a~justed os close to the bridge fa6e as possible co~sistent with easy access for the wood. Too wide an aperture allows· the
