Spindle of EN24 running in self lubricating bushes, screwed to take dog or drill chuck. Spindle may be locked by hand wheel during drilling operations.
3 positions are provided for tool support bar and retained by swing latch.
Linearbarsupports See drawing sheet4
Of grade 14cast iron.
Item A is fitted with 2 self aligning flange bearings that take 25~ linear bars. Thetop boss is bored to take the 20 ~ support bar and is slit to provide a clampingfacility. Item B hasa boxslidearrangementthat has vertical travel of 40 mm and has a fine adjust ment screw. The slide is fitted with 2 selfaligning flange bearings that again take 25 ~ linear bars. A self aligning flange bearing is fitted to take the top 20 ~ support bar.
The swivel feature ofthe self aligning bearingsthat allows them to be used on unmachined surfaces, also makes provision for the insertion or removal of linear bars atthe front ofthe machine, and allows the inclination ofthe linear bars by the slideway for use in taper machining.
Vertical slide table assembly See drawing sheet 5
The assembly is made up of 2 grade 14 castings A and B, the slideway a is of flat ground stock and the retaining strips are of phosphor bronze.
A shallow box slide is machined on slidewaytable
A and is a slide fit with slideway strips a that are secured to backplate B. The retaining strips bare secured to slideway table Ato complete the slideway arrangement. With the backplate secured to the front edges of 2 legs, initial alignment oftableface iseffected by 2 adjusting screws C. Table is raised and lowered through a handwheel and screw 15 ~ x 4,0 pitch trapezoidal, with a travel of approx 150 mm.
Complementary to this assembly is the right angle plate C. See sheets 6 and 7. This is of grade 14 cast iron and is secured totableA in anyone of 5 positions, as shown or about face, by means of pillars d.
Thetop edge is machined as a half dovetail to make provision for the free run of anyworkpiece holding fitment as may be required.
Basic assembly See drawing sheet8
This shows the standard working attitude with linear bar support brackets in their normal positions.
With the front linear bar removed and with the rou tercarriage moved up alongside bracket B there is access for free hand turning as function 1. With the front linear bar inserted or with the leadscrew and handwheel in this position, and with the router mounted in the carriage, functions 2,3, and 4 are carried out.
Bracket B is fixed in position shown and need never be removed. Bracket A however, is able to be slid along the bed towards bracket B by slackening the single clamping pin in the foot, the linear bars being secured in this bracket only are carried along with it.
The headstock is now free to pivot to front facing position.
lndexingandcable arrangementforspiral rout- ing See sheets 9, 10, 1 and 12
Index arrangement sheet 9.
With the vee pulleys removed the index plate a is detached from the headstock and secured to keywayed bush b. The selected size drum C is secu red to index plunger arm d which is a run fit on bush b. The whole is locked onto spinbdle by keyway and handnutwith a free run existing between index arm and index plate. The cable is secured by a small loop and peg in the centre of the drum and is then wound round the drum fully on one half- according to whether LH or RH helix is being cut- SHEET 11, and one turn on the other half. The cable is then taken roundthecornerbracket-SHEET11 - and anchored ontothe routercarriage and or round the bracketto pulley, and then to the carriage tensioner. SHEET 10.
With the router mounted in the carriage, function 5 may be carried out.
Plain indexing arrangement See sheet 13 With thevee pulleys removedthekeywayed bush a and index arm b are locked up with handnut. If the clampscrew is slacked it allows a free run between arm and bush, thus allowing the indexing to be freely put relative to any point on the workpiece.
This indexing arrangement is used in functions 3 and 4 and part of function 10.
Routercarriage See sheet 14 Has 2 aluminium LM4 castings A and B. Thefront plate C is of BDMS and houses the spring loaded, quick release leadscrew engagement. The bushes are self lubricating and take the 25 ~ linear bars orthe 25 ~ x 5.0 pitch trapezoidal leadscrew. When the plain linear bar is used instead ofthe leadscrewthe engagement is held clearbythefingernut.
Thesupportcasting B is machined so that it may be fitted on either side of carriage. The router can be mounted on it's rods in 3 positions of height and so accommodates the longer cutters that are used when machinig mortises orslots, or drilling.
Planertable See sheet 15 This assembly is made up of 4 grade 14 castings A,
B, C and D.
A and B are secured together and need never be taken apart. C is secured to A by 2 spring loaded thu mbn uts, and when screwed hometheworking face of C is 0.5 behind that of B, and this is the amount of stock removal as the workpiece is passed across cutter face.
Item D is only fitted and used during a thicknessing operation; it is aligned by 2 tenon slots and it provides a throatwidth of 103 with thumbscrew adjustment down to a throat width of 3.0. It is quickly detachable by unscrewing 2 knurlheaded setpinsand with the tenon secured to it it leaves the table surface free of projections when it is detached.
When thicknessing item C acts as a pressure pad by unscrewing thumbnuts back to circlips and so allowing 4.0 of spring loaded movement, thereby making provision not only for support, but allowing the maximum stock removal of 3.0 to be taken.
Cfrcularsawattachment See sheet 16 Guard and end coverofLM4aluminium castingsA and B. ItemAis located and clamped to bearing housing by its split collar.
The end cover B that has a self lubricating bush is also a steadyforthe arbour and is located to A by its rim flange and secured by 3 pins. The arbour body is of extruded aluminium and is spigot located to spindleflangeand retained by4pins.
The saw location spigot and journal is oftoughened EN24 and is screwed and pegged into arbour body.
The locknut is toughened EN24 and the washer of extruded aluminium has a D holeto prevent unscrewing during reverse running. Fence C is of cast
LM4 aluminium and is located by 2 8.0 ~ guide rods that provide an adjustment for 0- 0-450 mm. The fence can be used as shown or aboutface, or bythe same token, on the other side of the table.
Beltsandingattachment See sheets 17and 18
100 mm wide sanding belts are used andthese run on rubber sleeved LM4castaluminium rollers. The drive roller is spigot located onto spindle flange and secured by4pins.
The slave roller is cambered to promote good tracking and hasa20$shaftthat runs in pillow blocks mounted on their own base atop the headstock.
Tracking andtensioning is controlled by singer operated cams, and these along with the pillow blocks and their base can remain permanently in situ.
Thespring loaded sanding table as on sheet 18 is of 2 grade 14 castings and allows a capacity under the sanding rollers of 0-100. It is possible obviously to sand a board 200 wide by running it through and then turning it round and running it through again.
Roller steady See sheet 19 The steady bodyA,cam dise B and roller arms C are all of grade 4 cast iron.
When the cam disc is rotated in direction of radial arrow the roller arms rotate towards the centre reducing from its maximum capacity of 75 ~ down to 15 ~. The cam disc is locked in position bythumbscrew.
The steady is retained to slideway by single clamp and pin in the heel.
Planing head See sheet20
Made from extruded aluminium bar, it locates with register onto spindle flange and is retained by 4 pins.
Tool bits are either of H.S.S. or carbide tipped and are retained in their slots by tapered blocks.
Tool bits are set 0.1 proud of face Awhilstface A is in line with working face of part B on planertabie.
Flatsanding discs See sheet2 1 Two sizes provided, 120 8 and 300 8 made from marine ply with steel bush insert screwed to fit spindle nose.
