Materials:
- car wheel rim;
- wheel hub;
- profile pipe 15x15 mm;
- steel round timber d10 mm;
- pipe d15-20 mm;
- a steel steering wheel from a tractor or a round timber ring;
- high pressure hose of the required length;
- quick-release connectors for the compressor.
Making a coil
It is necessary to measure the diameter of the existing wheel rim. Based on the obtained parameters, you need to make a stand to mount it.
To do this, take 2 identical sections of profile pipe, the length exceeding the diameter of the disk by 20 cm. They are aligned in parallel and a hub is welded to them in the center.It is important that if the hub studs do not coincide with the mounting holes on the disk, then they must be knocked out before welding.
To the stand at a right angle you need to weld a base in the form of a frame made of a welded profile, which will be required for attaching the reel to the wall. It consists of 2 pipe sections with 4 jumpers between them. Of these, 2 are welded along the edges of the frame and 2 opposite the profile of the stand. Holes are drilled in the outer lintels for attaching the sole to the wall.
At the next stage, a roller mechanism is made to control the angle of rewinding and unwinding of the hose. It consists of 2 profile pipes with a jumper, between which 2 pieces of round steel are welded with round pipes placed on top.
The result is rollers for sliding the hose. Their length should be equal to the width of the disk. This structure is welded to the stand with the hub. The frame with rollers is not located in the center, but is shifted to one side.
Now the stand can be painted.
Next, you need to make a steering wheel for convenient rotation of the disk by hand. To do this, a steel steering wheel from an old tractor is welded to it. Instead, you can use any rim or ring made of round steel, as long as its diameter is slightly larger than the disk. You also need to cut a window on the side of the disk to allow the hose to enter.
Let's paint.
The disc is then welded to the hub or simply welded to it.
The coil is secured with anchors to the wall through holes in the base.
A hose is screwed onto the disk.
In this case, its edge is first inserted into a hole cut on the side, and then passed through the center of the hub.
After winding the hose, a quick-release connector is installed on its edge protruding from the hub, and the compressor tube is connected to it.The second end of the hose is passed through the rollers and the necessary equipment is installed on it.
The reel allows you to unwind the hose to the required length, be it 1 m or 20 m, and then quickly reel it back. Additionally, you can weld several hooks on the bottom of the sole for convenient storage of pneumatic tools.
The reel turns out to be very strong and reliable; its maintenance only requires occasionally lubricating the rollers.
