Comparison of Current Cutting Methods, and Miter Cutting Slide for Jig Saw

(20) Using a Standard Miter sawit is Bulky, usually on Sawhorses or on a platform, and there is difficulty of dealing with longer material needing cutting.

(21) Using a Radial Arm Saw. Difficult, requires Dust Collector, it has to remain stationary, not easily movable in a construction site.

(22) Using a Band saw, it is on a stand, ok for larger objects, but bulky for cutting thin long objects, not easily movable for frequent cuts, usually stays in one or two locations on a construction site.

(23) Saw blade TEETH width, typical saw blade (circular saw, table saw, radial arm saw, miter saw), width is very wide between teeth, this makes it difficult to do finer cuts on more delicate material. It is much easier when using the Jigsaw and stand, with finer blades. The Jigsaw has availability of various blades, of various teeth width, to help match it to the material being cut.

(24) Detailed Description of Miter Cutting Slide for Jig Saw

(25) SEE FIG. 1, FIG. 2, FIG. 3, and FIG. 4, for some views that reflect the following assembled sections of the MITER CUTTING SLIDE FOR JIG SAW. This provides a review of the device. Then a SEPARATE SECTION below shows the COMPONENTS and CONSTRUCTION of the different parts of this device.

(26) The MITER CUTTING SLIDE FOR JIG SAW is composed of a straight narrow board (this is the SLIDE (310)), onto which the JIG SAW (309) will be fastened, facing forward, on the underside of the SLIDE (310). The JIG SAW (309) is approximately centered front-to-back on the SLIDE, and the BLADE when inserted will protrude through the centered SLOT in the SLIDE, at approximately the center length of the board. The JIG SAW is fastened (in working prototype) with 4 countersunk machine screws, with 4 clamps placed against the base of the JIG SAW, and then spacers and wing nuts are attached to the machine screw, to fasten the JIG SAW (309).

(27) SPACERS are added, over the CLAMPS, before the WING NUTS. These spacers allow the wing nut to sit higher to be tightened, so the user's fingers don't have to tighten the wing nuts when it is close to the base of the saw. It is easier to tighten when it sits higher.

(28) PROTOTYPEthe clamps used are ELECTRICAL CONDUIT CLAMPS, because of being easily available. A better clamping/securing system is possible, once actual production would start; various clamping systems could be used that may be easier to implement, but this current prototype method actually works very well.

(29) The SPACERS used consist of 3 of 5-16 nuts, drilled out so no threads exist, Making it easy to slip over the -18 bolts.

(30) IMPROVEMENT during PRODUCTIONa more mass produced spacer and clamp system.

(31) The SLIDE (310) has an outlined area (prototype used inch hardboard) which outlines the base of the JIG SAW (309), so that when clamped down, it is centered correctly.

(32) The SLIDE (310) is marked to show the maximum backward position it can be pulled to, without falling out of its supporting stand, so that the user can see how far back it can go safely. It is also marked with the maximum forward position it can go, so the user is aware, but the SLIDE is also set to STOP at the maximum forward position, so the user does not cut through the BACKPLATE (369) that supports the material being cut. (SEE IMAGE SECTION)

(33) IMPROVEMENT during PRODUCTIONthe position of the JIG SAW (309) on the SLIDE (310) will be unique to each brand of JIG SAW (309), so there can be a template provided, to show which holes need drilled, to position each brand of JIG SAW at the central part of the SLIDE, and this also will help adjust balance for each unit. The BLADE should always be at the same position, so the BOTTOM of the SLIDE would have the templates designed for marking. ALSO, it may be possible to pre-drill holes, depending on the varieties of JIG SAWS on the market, and if the product would get aimed at the top 5 jig saws, for example, thus decreasing the number of templates needed. In all practicality, this MITER CUTTING SLIDE FOR JIG SAW would not be suited to all jig saws, not because of a deficiency of the MITER CUTTING SLIDE FOR JIG SAW, but because of the limitations of some jig saws, which are just entry level, lack a variable speed trigger, or an adequate base plate.

(34) IMPROVEMENT during PRODUCTIONa rear handle and trigger system, to attach to the underside of the SLIDE, with a cable type system that would connect and control the variable speed trigger of the JIG SAW. This would allow the operator to not have to reach as far downward to control the JIG SAW, but more rearward onto a more accessible handle with a trigger on it.

(35) The second part of the MITER CUTTING SLIDE FOR JIG SAW is the TABLE (348). The TABLE (348) consists of a inch piece of hardwood, marked with degree markings of 90, 45 (left and right) and 22 (left and right). The BACKPLATE (369) (third part) will fit onto the TABLE (348), easily adjustable with just two pins, and line up with the angled markings. The TABLE (348) is made of thin material, because a limitation of the JIG SAW (309) is the length of the BLADES. Mass production only produces blades about 4 and inches, although some 6 inch blades are made, but in limited teeth configurations. The thinner the TABLE (348), the more blade will be able to be visible and be used to cut thicker material.

(36) IMPROVEMENT during PRODUCTIONthe SLIDE (310) can also be made of thinner material, once production starts, and we evaluate what thinner material will have the support strength similar to the current prototype which used inch plywood. The thinner the SLIDE and TABLE are, again the more blade is usable.

(37) The TABLE (348) has two inch pieces of wood, sandwiched in the middle at the front third of the TABLE, that straddle the SLIDE. Then there is an additional inch piece of wood, on the underside of those pieces, that cross UNDER the SLIDE path, and this is what supports the SLIDE from falling out, and allows forward/backward sliding and cutting.

(38) The third part of the MITER CUTTING SLIDE FOR JIG SAW is the BACKPLATE (369). This consists in prototype, of an angled piece of aluminum, supported in the center by a block of wood. This supporting piece of wood is epoxied to the aluminum, and this allowed me to cut out a small triangle, spanning the 45 degrees left and right, to allow the blade to cut directly through the material being worked on, and NOT cut further through the BACKPLATE (369), and still allow the BACKPLATE to have structural integrity and remain straight and supportive to the material against it. The BACKPLATE is adjusted on the left and right edges, with a removable pin, which fits into precision holes in the TABLE, so that the desired angle can be selected, and the material placed against the BACKPLATE, and cut.

(39) IMPROVEMENT during PRODUCTIONthe BACKPLATE (369) can be designed to allow for rotating around a central point, with a central locking nut, thus bypassing the limitations of just specific common angles, allowing for infinite angle adjustment. Also, for safety, a plastic shield could be added to the BACKPLATE (369), which rises vertically, and then comes forward horizontally, thus covering the cutting site, and the blade, yet allowing visibility of the cutting area.

(40) The fourth part of the MITER CUTTING SLIDE FOR JIG SAW is the BASE (329), which in the prototype is a 9 inch high frame, with 4 corners at the top, which support the 4 corners of the TABLE (348). The corner supports on the BASE (329) support both the left-right, and front-back, edges of the TABLE (348) corners, so the table cannot slip out of the BASE when the SLIDE is being moved. The BASE has a board on the bottom of the legs, in the front and the back, that extend about 3 inches beyond the front and back edge of the BASE. This allows for support and ability to clamp, the front and back edges, adding more stability.

(41) The BASE (329) is designed to be slightly higher than the height of the JIG SAW (309). This allows for free movement of the SLIDE (310), with the JIG SAW attached, and for easy ability to reach the speed control/trigger of the JIG SAW.

(42) NOTE, as above, various JIG SAWS may need a different height, and the BASE (329) can be easily adapted to an adjustable height method, to accommodate different JIG SAWS. ALSO, as noted, NOT ALL JIG SAWS may be able to be accommodated, not because of the MITER CUTTING SLIDE FOR JIG SAW but because of a specific JIG SAW design, or difficulty to reach the trigger/speed control when the JIG SAW is mounted upside down.

(43) IMPROVEMENT during PRODUCTIONthe BASE may be converted to folding arms that rotate up to the side of the TABLE, thus increasing portability of the unit, and ability to then extend the legs of BASE when ready to do cutting.

(44) IMPROVEMENT during PRODUCTIONthe BASE height may be adjusted by ADJUSTABLE LEGS, thus taking care of height accommodations for various models of JIG SAWS, to allow adequate clearance under the handle/trigger mechanism of the JIG SAW when attached to the SLIDE

(45) The BASE (329) design allows for insertion of the TABLE (348) with marked angles and BACKPLATE (369), which allows the JIG SAW and SLIDE to move, while the BASE and TABLE remain stationary. This allows the operator to hold the JIG SAW handle, and speed control, and move the JIG SAW and SLIDE forward and backward relative to the TABLE.

(46) THE BASE (329) is also designed to accept a SLIDE SUPPORT TABLE (349), where the HARDBOARD with marked angles is replaced with a more sturdy inch thick10 inch wide10 inch front to back board (or other sturdy production material.) The SLIDE ALSO was modified to be longer at the rear portion. THEN, with the JIG SAW (309) mounted, the JIG SAW and SLIDE could be mounted into the BASE which has the SLIDE SUPPORT TABLE, thus making the JIG SAW and SLIDE stationary, and allow the TABLE to be placed on the FRONT of the JIG SAW (309) and SLIDE, and that TABLE to be moved, relative to the JIG SAW and SLIDE. In that case, the operator does not have to control the speed of the JIG SAW, as the trigger would be placed in an always-on position.

(47) The versatility of having the JIG SAW and SLIDE move, relative to the TABLE (348), OR having The TABLE (348) move, relative to the JIG SAW and SLIDE WITH REAR EXTENSION (311), Allows great versatility for the operator of the device, depending on types of cuts to be made and type of material to be worked with.

(48) Operation of Miter Cutting Slide for Jig Saw

(49) SEE FIG. 1, FIG. 2, FIG. 3, and FIG. 4, for some views that reflect the following assembled sections of the MITER CUTTING SLIDE FOR JIG SAW. Then a SEPARATE SECTION below shows the COMPONENTS and CONSTRUCTION of the different parts of this device.

(50) Operation of the Jig Saw (309) and Slide (310) being Moved, while the Base (329) and Table are Stationary

(51) When operating, the material to be cut is placed on the TABLE, and the SLIDE (310) is pulled backward, to allow correct material placement, and correct angle adjustment. When ready to cut, the user grasps the JIG SAW (309) handle, pulls the trigger to start the machine, and moves the JIG SAW (309) and SLIDE (310) forward, at their own pace, to cut into the material, which the user is holding against the BACKPLATE (369) with the other hand. If the material is long, it can be easily supported on some blocks, or other raised object, OR if using the MITER CUTTING SLIDE FOR JIG SAW at ground level, the material may be left on the ground and flexed enough to comfortably rest on the TABLE, since the whole apparatus is only about 10 inches above the floor. Once one end of a long piece is cut, the MITER CUTTING SLIDE FOR JIG SAW can be easily moved to the other end of the material (which may sometimes be 12 to 16 feet long) and perform the cut at that end, rather than trying to manipulate a 12 to 16 foot piece of material turning it end for end.

(52) PRODUCTIONSAFETYcurrently in PROTOTYPE, the blade does not have a guard over it. A guard has been thought of, and is noted above in the IMPROVEMENT IN PRODUCTION section for the BACKPLATE (369). BUT sometimes, with a saw such as a JIG SAW (309), there is no guard over the blade ANYWAY, when it is used. The operator has one hand on the JIG SAW handle, and another hand (or clamps) on the material being cut, and is moving the saw at a controlled pace. AND, the visible blade allows for easier lineup to the cutting lines on the material being cut.

(53) Operation of the Table being Moved, while the Jig Saw (309) and Slide with Rear Extension (311) Remain Stationary

(54) The WORKING PORTION of the SLIDE with REAR EXTENSION (311), including the movement marks, hole for saw blade, and JIG SAW (309) mounting screws, and the TABLE (the table with the angled hardboard portion which mounts the BACKPLATE (369)) are IDENTICAL in this operation as compared to the operation where the JIG SAW (309) and SLIDE move relative to the TABLE (348)

(55) In this case, a SLIDE WITH REAR EXTENSION (311) is created which is 5 inches longer in the rear. This portion of the SLIDE WITH REAR EXTENSION (311) then fits into the SLIDE SUPPORT TABLE (349) (which has the supporting board rather than the thinner hardboard marked with angles), which fits into the same BASE (329). This BASE (329) plus SLIDE SUPPORT TABLE (349) is then clamped into position, and the TABLE (348) with BACKPLATE (369) and hardboard with angles, is placed on the FRONT of the SLIDE WITH REAR EXTENSION (311), and then that TABLE (348) can be moved relative to the stationary JIG SAW and SLIDE WITH REAR EXTENSION (311).

(56) (I did not build a prototype of that SLIDE WITH REAR EXTENSION (311) and SLIDE SUPPORT TABLE (349). I do have the sketched drawings of that combination) OPERATION IN REAL-TIME of MITER CUTTING SLIDE FOR JIG SAW Prototype

(57) These show the prototype in operation. These help to understand the usefulness of this SLIDE system. The system is detailed in normal line drawings, but these greyscale figures provide a day-to-day usage of the system.

(58) FIG. 1 This shows the unit with its main component parts, taken to worksite, being set up.

(59) The TABLE 348 goes into the BASE 329, the BACKPLATE 369 goes onto the TABLE, and the JIG SAW 309 mounted to the SLIDE 310 goes into the TABLE.

(60) FIG. 3 This shows the unit with its main component parts, in the configuration where the TABLE 348 will move, relative to a STATIONARY SLIDE with REAR EXTENSION 311. It also shows a piece of material 312 (not part of apparatus) which the operator is preparing to cut.

(61) FIG. 2 This shows everything assembled, ready for operation.

(62) FIG. 4 This shows the unit operational, similar to FIG. 2, with material in position to be cut, and here the TABLE will be moved toward the JIG SAW and SLIDE 311 to accurately cut the material.

(63) FIG. 17 This shows the JIG-SAW, attached to the SLIDE, positioned in the TABLE AND BASE.

(64) FIG. 17 BACKPLATE is attached to TABLE top, ready to have material positioned against this for cutting.

(65) Components and Construction of Miter Cutting Slide for Jig Saw

(67) COMPONENT 312PIECE of wood molding which is being cut (for demonstration, not part of construction of device)

(68) COMPONENT 309JIG SAW, COMPLETE (obtained separately from various tool supply sources, my device does not claim invention of the JIG SAW, my device is used to CONNECT and OPERATE available JIG SAWS or similar saws that are manufactured by others separately)

(69) PROTOTYPE has been built, the model allowing movement of the JIG SAW and SLIDE within the TABLE. But PROTOTYPE does not reflect all combinations for the MITER CUTTING SLIDE FOR JIG SAW. The descriptions of components, and other improvements reviewed, reflect advancements and modifications in design to allow for other cutting abilities and operator interactions with this apparatus. The PROTOTYPE as described thus does not LIMIT the design to only the prototype, but final and improved design can include (but not be limited to) modifications as discussed throughout this document. The design is not limited to the MATERIALS described in prototype, but may incorporate more varied materials based on availability in a more mass-production environment. Such materials may enhance usefulness and ability of this product (such as thinner SLIDE material which can make the JIG SAW BLADE more useful by having more of the BLADE exposed)

(70) WOOD PARTS are GLUED and BRAD-NAILED to each other during PROTOTYPE construction unless otherwise noted. During more mass production, other fastening methods may augment or replace the prototype method, making for easier assembly.

(83) 321 is placed across front of the two front 324, horizontal, its lower edge at 4 inches from bottom of the 324 pieces.

(84) 322 are placed left and right laterally; left one across the left outer edges of the two left 324, at 4 inches from bottom of the 324 pieces. Same thing for right side, right piece of 322.

(85) 325 placed at top front of the front 324 pieces, and at the top rear of the rear 324 pieces. The lower edge of 325 is placed at 8 inches from bottom of 324.

(86) 326 placed at left side of left 324 pieces, and right side of right 324 pieces, lower edge of 326 at 8 inches from bottom of 324 pieces.

(87) Placement of 326 and 325 allow for inch elevation above top edge of 324, so the TABLE can rest within these elevations, and thus allow for support of the TABLE to prevent forward and backward movement of table when supported by the BASE.

(88) BASE is designed to support TABLE when stationary and the JIG SAW and SLIDE combination move relative to the TABLE, and also to support the SLIDE SUPPORT TABLE when the JIG SAW and SLIDE combination is held stable at the rear position by the SLIDE SUPPORT TABLE, with the regular TABLE attached at the forward position and that TABLE moves relative to the JIG SAW and SLIDE combination.

(104) 306JIG SAW Hold-down bracket front (FOUR of them)in PROTOTYPE these were from electrical conduit connectors, with a 1 inch1 inch approximate flat face, then a curved part that goes over electrical conduit, but here they are used for fastening down the JIG SAW to the SLIDE. In the DRAWINGS the front and rear ones were drawn slightly differently due to my limited skill in drawing the JIG SAW and getting edges to line up. But the function of these brackets is flexible, and they can be modified easily to match various JIG SAW configurations.

(105) 307SPACERS (FOUR of them) to allow elevation of 308 above the JIG SAW edge, to allow for easier tightening.

(106) 308WING NUTS, 18 (standard configuration), to tighten down the 307 onto the 306, thus fastening the JIG SAW to the SLIDE.

(107) Slide Construction

(108) 301 is cut, and then CENTER HOLE for BLADE is cut, at indicated position. GUIDE MARKS are added at indicated positions.

(109) 301 is flipped over to view the bottom. 302 are placed on the face of bottom of this, with the front edge of 301 is placed at 11 inches from front, on left and right side, and the long part of 301 faces front to back.

(110) 303 is placed with the 5 inch part lying across the 5 inch face of 301, with the front edge of 303 at 17 inches from front edge of 301

(111) HOLES are then drilled for the 304 bolts at indicated positions. 301 then has the TOP FACE have countersinking holes drilled to accommodate the tops of the bolts so the top of the 304 are flush with top face of 301.

(112) 304 are then epoxied into the top portion of 301 so that 304 do not rotate when the fastening wingnuts are applied to 301 when attaching JIG SAW.

(113) SLIDE construction to this stage has the JIG SAW and SLIDE ready to be used in mobile status, within the stationary BASE and TABLE combination.

(114) The FOLLOWING steps of adding 305 do NOT AFFECT any of the operation of the JIG SAW and SLIDE moving relative to the TABLE. That is the core part of the apparatus. The addition of 305 allows more versatility of the apparatus.

(115) Adding 305 to the REAR of the SLIDE adapts the SLIDE adapts it to operate in STATIONARY position, with the TABLE being the mobile part of the unit. 305 can be added to REAR part of 301, glued or epoxied or otherwise fastened permanently, and it could then be used for both stationary status (its rear portion being mounted in the SLIDE SUPPORT TABLE), or for mobile status (sliding freely in the forward TABLE). However, that permanent attachment makes the SLIDE somewhat more bulky for mobile use (slightly more cumbersome for operator to reach the JIG SAW).

(116) A more flexible attachment method which would allow easy attachment AND removal of 305 would be to either drill matching dowel rod holes in the front face of 305, and in the rear face of 301, about inch in from left and right edge, and have long dowel rods that allow inserting of dowel rods into 301 rear, then slide 305 front face onto the dowel rods. Also a Mortise and Tenon joint could be used. Either way, all this can be evolved more in production, but in no way detracts from the operation of the JIG SAW and SLIDE combined with TABLE.

(117) FIG. 17 This shows the SLIDE, inserted into the TABLE. The BLADE is in the TABLE SLOT 350. The TABLE SLOT gets cut on the first use and first pass of the SLIDE onto the TABLE, by the BLADE. Subsequent uses now have the SLOT as a guiding path, for the BLADE, to precisely cut the material.

(142) 364Pins (metal, TWO of them), inch diameter, 2 inches long BACKPLATECONSTRUCTION

(143) 362 is main component of this. It is right angle aluminum, and the inch high edge of it faces forward. Holes are drilled inch from back flat edge, 1 inch from each end, to accommodate 364 pins when placing the apparatus onto the TABLE.

(144) 363 pieces are epoxied (or other alternate fastening method) to the flat outer ends of 362, to allow for clamping the BACKPLATE to the TABLE if needed for extra stability.

(145) 361 is fastened with inch edge facing forward, with its center front matching the center rear part of the inch face of 362.

(146) 360 is fastened with its inch high face matching the rear inch face of 361, with flat inch side of 360 attached to bottom of 361. This allows for support of the rear of the BACKPLATE, so all its edges are supported equally and it lies in a truly flat position.

(147) At the front center face of 362, a notch is made (which includes notching the front of the attached wood piece 361) so that when materials are being cut, the blade does not cut further into the BACKPLATE, and also so that if a blade designed for wood is used, it does not get damaged by cutting into the aluminum (or other alternate metal material) of 362.
