A tow dolly, also known as a trailer dolly, is an efficient way of towing an automobile. This type of dolly will carry the weight of the vehicle in tow on a bed that rests on an axle. A tow dolly is slightly shorter than a typical trailer, thus making transportation easier since it will reduce the length of the entire tow assembly. You will need welding experience or a welding professional to complete the job.

Things you need
- Shaft pipe (1 inch in diameter, 30 inches in length)
- Handle pipe (3/4 inch by 10 inches)
- Support pipe (5/8 inch by 7 inches)
- Axle pipe (3/4 inch by 14.5 inches)
- Upright pipe (1 inch by 9.5 inches)
- Wheels (2, 8 inches in diameter)
- Washers (4, 1.5 inches in diameter)
- Cotter pins (4, 2 inches long)
- Trailer ball
Drill holes approximately 1 inch from both ends of the 14-inch long, 5/8-inch diameter pipe with a power drill. The holes should go completely through each side of the pipe. They should also be on the same sides of the pipe. These holes will be for the cottar pins.
Slide a washer and then a wheel over both ends of the axle pipe.
Insert cottar pins in the holes at both ends of the axle.
Press the wheels and washers outward against the cottar pins. Mark the location where the inner side of the washers rest with a permanent marker.
Remove the wheels and cottar pins from the axle.
Weld the two washers to the axle in the location you have marked.
Flatten both ends of the shaft pipe with a hammer. Flatten 2 to 3 inches of the pipe until it is squared.
Connect the handle pipe and the shaft pipe. Weld one end of the shaft pipe to the centre of the handle pipe. This will make a "T" shape.
Connect the shaft to the axle pipe. Weld the remaining free end of the shaft pipe to the centre point of the axle pipe to create another "T" shape.
Flatten both ends of the support pipe and one end of the upright pipe with a hammer. Bang flat the pipe ends until they are square.
Connect the axle and the upright pipe. Weld the flattened end of the upright pipe at a 45-degree angle next to the shaft pipe.
Attach the trailer ball to the free, non-flattened end of the upright pipe. Insert the pole end of the trailer ball into the end of the upright pipe. Weld together the two pieces.
Slide a wheel on each side of the axle. Insert cottar pins into the holes on the ends of the axles to secure the wheels in place.
Bend back the legs of the cottar pins so they are aligned with the roundness of the axle.
