Designed for long and bulky parts, rafters or metal profiles, this sawing table is completed by two height adjustable maids. Offered by Jean-Marie HASSE, it guarantees precise and efficient serial machining.
Achievement: approx. 25 hours
Cost: approx. 99 €
Mini equipment: arc welding machine, grinder, drill
See the plan of this realization (in pdf): A sawing table well served: the plan
The main element, the table, is made of locksmith irons of different sections assembled by arc welding. It is mounted on four wheels to facilitate its movement. The 19 mm chipboard top is covered with 5 mm thick aluminum plates that can easily be removed for fitting power tools. Two supports equipped with guides and stops, offer an additional range of 800 mm: it is appreciable, particularly for the series machining. The two maids provide good stability to heavy and bulky parts. They can be arranged to accommodate large, narrow or cylindrical parts.
It is perched on four legs of 25 x 50 mm profile, stiffened at the bottom by two cross members joined by a central spar. These three parts being cut into the profile of 20 x 40 mm. To form a uniform frame, a tray support frame is welded to the top of the feet. Its four sides, 25 x 25 mm angle, are mitered. Before definitive welding, it is recommended to point all the parts in order to correct any errors.
■ The feet each receive a 6 mm flat iron plate, drilled and tapped for fixing the swivel castors. A 22 mm chipboard is screwed onto the lower rails and spar. It is notched at the corners at the feet. The saw table is also equipped with an intermediate shelf. In a 16 mm laminated panel, it rests on two support brackets (section: 10 x 30 mm), screwed on both sides on the base at the desired height.
■ The table top is held in place by means of 5 mm diameter bolts, pushed in from below. Its three trim plates (center and ends) are fixed with the same screws but from above. The central plate, three times wider than the other two, allows the attachment of a radial saw (different holes are expected depending on the model). The other two, identical, receive the extension brackets and slides. If it is desired to remove the plate / saw assembly, holes must be provided in the plate large enough to pass the saw mounting nuts.
The frame of the finished table, wheels are screwed under the plates welded to the base of the feet. They will facilitate the movements, those with brake stabilizing all during work.
To enlarge the support surface, two supports covered with an aluminum shelf are screwed to the ends of the plate. Made of a beveled fir piece at the end on the outside, they have here 80 x 80 mm section but their thickness is again to be determined according to the base of your saw to obtain a continuous work plan.
■ A lower plate, made of 5 mm aluminum, provides the connection between the support and the table. For this reason, it has two threaded holes, for Ø M10 threaded rods whose heads disappear in Ø 25 x 15 holes drilled in the wood. These screws must be long enough to be tightened under the plate by a nut, by inserting a washer.
■ Fixing of shelves and plates, drilled with countersunk holes, is carried out with 5mm bolts. A slider can be screwed on the side of each support to facilitate the length of workpieces.
A simplified reading
Covered with an aluminum plate, the extension support is equipped with a ruler, fixed on the edge, which allows a direct reading of the measurements, providing a considerable comfort of work.
The stop system
Placed at the entrance of the table, it consists of two parts entirely metallic: one fixed, the other sliding. The first consists of a "stubfixed Ø 10 mm supported at one end by a flat iron (frame) welded vertically on a base The sliding part includes another stub, but Ø 8 mm, parallel to the first one to which it is connected by two adjustable slides each by means of two screwdrivers "violinIts end, table side, is also provided with a flat stop.For memory, the stub is a reinforced tube, especially used in the manufacture of hydraulic ducts.
The interchangeable stop device, with its sliding stub in solidarity with the extension bracket, facilitates precise adjustments, especially for series machining.
■ The base is pierced with two M8 threaded holes allowing it to be fixed on the table. The sliders, made of 12 x 20 mm drawn steel, must be drilled together at a diameter 2 mm smaller than that of the stubs. This makes it possible to adjust them to the reamer and to obtain a fat sliding.
■ The shims come from a Ø 20 mm drawn steel bar. Like the sliders, they are drilled and tapped at the M6 diameter for locking by violin screws. To increase your work possibilities, you can provide a second sliding stub whose end, threaded this time, can receive different types of stops: miter (see diagram) or other.
Focus on oblique cuts
For oblique cuts, simply mount at the end of sliding stub a stop having a suitable angle (red) which will ensure a good maintenance of the workpieces.
Their realization begins with the base: a sleeve of Ø 17/21 mm reinforced by a welded tripod. The latter, in a 20 mm angle, consists of three elements with beveled ends. The tube has a hole in the upper part equipped with a welded Ø M8 nut for the clamping handle of a sliding tube (or candle) of Ø 14/16 mm. Its length is calculated according to the desired working heights.
■ As for the sliding system, you will gain to make several interchangeable candles, each equipped with a different support depending on the parts to be machined. For example, a chamfered turntable soldered with two tapped holes for mounting a removable "V" cradle. In brassed angle, it has two lights to fix it by screws and nuts on the plate. For large pieces, a flat iron square support of 20 x 20 mm was produced, provided at each end with a Ø 20 mm wheel that slightly protruded from its upper face.
Support for tubes and cylindrical
Surmounted by a cradle "V", flanked by rounded notches, this support is intended for tubes and cylindrical profiles. Perfectly blocked, it is easy to saw and shape them.
At the end of the construction, the slag is removed from the welds and the cords are ground. The metal parts are then deburred and degreased, before being covered with an antirust paint. The aluminum surfaces are finely sanded with a metal abrasive and covered with a spray lacquer. It remains to lightly coat the slides of a silicone-based grease.
Provide two braked castors, to ensure good overall stability during work. A candle can be equipped with a roller stand that will facilitate the sliding of long pieces. A second sliding system will not be useless: you will be able to dispose of it at the exit as at the entrance of table.
