How to Make a Frame for a Hoist

Hoists are powerful lifting devices capable of raising the engine of a car, for example. However, to actually function, a hoist needs to be placed on a frame. A sturdy hoist frame isnt too hard to build out of some existing materials. The process is similar to building a swing set, but with some modifications to allow the frame to support immense weights. A wooden frame is capable of carrying an engine block.

Instructions

    1

    Place the three 2-by-6 planks together, so they create a 6-by-6-inch beam. Glue the planks together. Clamp the beam down.

    2

    Use a drill bit marginally wider than the 7-inch bolts. Drill all the way through the beam, then push the bolt through and screw the nut into place. Repeat with the other 7-inch bolts, spacing them evenly along the beam.

    3

    Lay two 2-by-4 planks on top of one another to make a 4-by-4 beam. Screw the planks together with 3-inch wood screws, then flip the piece over and screw from the other side. Repeat three more times to make four legs total.

    4

    Arrange two legs to form the side of an A frame. The top-most corners of the planks should be about 6 inches apart, and the bottoms of the planks should be about 7 feet apart. Glue and clamp the beams together.

    5

    Place a 2-by-4 across the bottom of the A frame, so that it meets with both outer corners of the A frame. Trace the bottom of this piece of wood with a marker.

    6

    Cut off the bottoms of the wooden frame.

    7

    Cut the remaining 2-by-6 pieces into four 2-foot planks. Place one of the 2-foot pieces about 6 inches below the top of the A frame and screw it into place with the wood screws. You need at least three screws on each side of the A frame.

    8

    Place a 2-by-4 plank about a third of the way up your A frame. Line up the end of the 2-by-4 with the side of the A frame. Cut the excess beam off the end. Screw the beam into place.

    9

    Place the excess beam from the previous step on the A frame toward the bottom. Cut off any excess wood. Screw this into place.

    10

    Flip the A frame side over and attach a second set of cross beams. You need a 2-by-6 beam 6 inches from the top and two more 2-by-4 pieces along the side.

    11

    Repeat the previous steps to make a second A frame side.

    12

    Trace the end of the 6-inch beam onto a piece of cardboard. Cut out this template.

    13

    Align the template so that it rests on the top of the 2-by-6 plank. Trace the template.

    14

    Cut the excess wood to create a void inside the A frame where you will store the beam. Repeat the tracing and cutting with the other A frame.

    15

    Slide the end of the 6-inch beam into the slot atop the A frame. The two pieces should be at a 90-degree angle. Screw the beam into place. Repeat with the other end of the beam and the other A frame.

    16

    Hold a 2-by-4 plank at a 45-degree angle between the 6-inch beam and the middle 2-by-4 on the A frame. Screw this into place and trim off the excess.

    17

    Attach your hoist to the middle of the 6-inch beam.

How to Make Denso Shims

The accelerator pedals in Toyota automobiles either come from Denso or CTS manufacturers. The CTS accelerator pedal has a demonstrable tendency to stick because of a friction arm design. Shims are a necessary, but temporary, modification that brings the pedals closer to the quality found in a Denso accelerator. These shims can be bought and installed at Toyota dealerships. But a Denso shim also can be crafted with basic metalworking skills.

Instructions

    1

    Determine the thickness required for the shim. Locate the part number stamped near the top of the accelerator pedals neck. A chart in the accelerator module recall documentation indicates the shims required thickness based upon this part number. This value ranges from 0.055 inches (1.4 mm) to 0.114 inches (2.9 mm). A majority of these replacements will require either a 0.070-inch (1.8 mm), 0.079-inch (2.0 mm) or 0.091-inch (2.3 mm) thickness.

    2

    Use metal cutters to cut a square shim out of steel measuring one inch (25 mm) on each side. The thickness of the shim should fall between 0.008 inches (0.2 mm) to 0.020 inches (0.5 mm) greater than the requirement outlined in Step 1.

    3

    Position the shim in a metal press so that a 0.079-inch (2 mm) lip is exposed on either side. Use the stamp to squeeze the metal until the center of the shim is the required thickness, but the lip remains at its original thickness. The result resembles a "U" shape.
