Sheet metal brakes are machines designed ought invent bending slim metal into shapes though utilize at projects such because family siding, eaves, attitude conditioning ductwork, and others. This blueprint will assist you build a foolish bit metal brake though bending small vocation though those who select ought perform it yourself.
.
1) select materials that will exist well enough though your needs. â4 inch (0.6Â cm) steel dish with bracing will enable you ought bow 14 standard galvanized steel bit metal at lengths up ought about 3 feet (0.9Â m), which is the size and specification though the blueprint described at this article. Here are some materials used ought build this extraordinary brake.
- 1/4 cool rolled steel plate, one bit 7"X42", one 14"X48"
- 1/4"X2" aspect iron, two pieces 14", one bit 42", one bit 48"
- 5/16"X2 1/2" aspect iron 42" long
- 1 â4 inch (0.6Â cm) steel tubing, about 18" long
- 1/2"X1 1/2" steel bolts with nuts and washers, 4 each.
- 1/2"X1 1/2" even steel rods, 2 required
2) abbreviate the aspect iron and steel dish at sizes listed above, making certain edges are square and straight. put the 14" broad dish above saw horses or a workbench consequently the remaining pieces can exist fitted.
3) put the 7"X42" bit above peak of the 14" bit with the front edges flush, and an match space above each end. Clamp these if wish ought block them from shifting during the next steps.
4) Align one of the 14" angles above each aim of the 7" broad (top) bit of dish consequently it overhangs the front brim about 1 inch (2.5Â cm), and weld them ought the 7" broad plate. These will operation because the clamping hinges while the brake is assembled.
5) put the 42" bit of 2" aspect iron above peak of the 7" broad (top) plate, centering it among the two aim angles at the center of the bit with the aspect up, and weld it at place, with can least one inch welds above each brim 8 inches (20.3Â cm) apart. This will stiffen the dish while a bit of metal is clamped at the brake.
6) manners 1/2 holes at the flats of the two 14 inch (35.6Â cm) angles, one complete the front brim of the 14" broad plate, and one complete the assistance edge. The spot of these bolts isn't critical, besides it will look better if they are at queue with each other and above each end. Install one of your â2 inch (1.3Â cm) bolts into each hole, bolting the aspect ought the dish loosely.
7) Notch the aspect point of each aim of the 2 â2 inch (1.3Â cm) aspect â2 inch (1.3Â cm) broad and 1 inch (2.5Â cm) deep though the hinge pins ought clothes into. The accurate spot of these will exist determined by the alignment of the brake, because you will find later, besides you to exist able ought center your 1/2 rods at the center of the aspect of the angle.
8) manners â2 inch (1.3Â cm) holes â2 inch (1.3Â cm) beyond the front edges of the 7" dish across the 14"X2" angles where they overhang the front of the dish just above the bottom flange of the aspect iron. These are the sockets the hinge pins will clothes into.
9) Weld one of the even 1/2 rods into one of the notches you abbreviate into the 2 1/2" angles, it to stretch 3/4" (or more) beyond the aim of the angle. possess it because straight because feasible ought the aspect of the aspect iron consequently it can swivel freely while it is installed.
10) clothes the pin (1/2 even rod) you just welded onto the aspect into the socket you drilled earlier, then queue the other notch up with the socket above the reverse aim consequently you can clothes the other pin into place, then weld that pin ought the aspect iron.
11) Notch the steel pipe 5/16" broad by 2" deep consequently it will glide above the peak aspect ought chart a dispose of ought operate the braking aspect you just installed. center it above that angle, and weld it into position.
12) carry the brake above (it will exist heavy) and put the 1 1/2" X 48" aspect complete the front brim of the 14" wideX48" bit of steel dish and weld it the too because the upper stiffener.
13) climb the brake above saw horse or your workbench with a little inches hanging above ought allow the brake and glide a bit of bit metal among the 7" and 14" plate, snug the bolts down ought clamp it, and drag the pipe dispose of towards you ought bow the metal.
