REPAIR OF BIKE WHEELS BY YOUR OWN HANDS ON A SELF-MODE BENCH
I WANT TO SHARE A WAY OF MANUFACTURING TWO BENCHES FOR THE ALIGNMENT OF BICYCLE WHEELS AND TO TELL HOW TO CORRECTLY SUCH SUCH WORK. SURE THIS INFORMATION WILL BE USED BY MANY OWNERS OF CYCLING TRANSPORT.
STAND FOR RICHTOV
From the frame of an adult bike snapped back (front is not needed). A metal tube of a suitable diameter was pressed into the pedal assembly sleeve, bent at the edges and scalded at the junctions (photo 1). The stand is ready, you can install wheels of any diameter on it. When it is necessary to trim a slightly curved rim of the wheel, set it on the stand (photo 2) and start scrolling. Having determined the place of the irregularity, I check the tension of the spokes - I weaken the tension (I twist the key), and those that were deformed because of the deformation were too tight - I unscrew. Due to this, the rim takes the original flat form.
RICHTOVKA WHEELS ON PLANE
After several edits described above, the rim may acquire an oval shape, then you need to more carefully align the wheels with a “bare” rim. It is for this purpose that a simple device was made.
Cut a square with a side of 100 from a sheet of multilayer plywood. I took a perfectly flat bicycle rim, placed it on a plywood base and circled around the contour - this line will serve as a template. In the center of the circle in plywood drilled a hole along the diameter of the wheel axle. Measuring the radius of an even bicycle wheel, on the circumference line with a pitch of approximately 25-30, see the metal stops (see photo 3, see fig. On page 18). The fixture is ready.
To straighten a wheel without a tire and a camera, I install it between the stops (photo 4) In places where the rim does not stand up, I tap it with a rubber sledgehammer. When everything is in place, check the tension of the spokes, tighten the weakened bars.
I also use this device to replace the needles. I place an empty rim between the stops, place the wheel hub in the center hole (photo 5)
I start assembling by filling the housings of the housings in the sequence with the head on the left and the head on the right (photo 6). Then, distributing the spokes in four directions (divided into four equal parts), fix them on the rim.
Important!
At the first baiting of the threaded nipples, the direction and sequence of the wheel should be clearly observed. For example, in the rear wheel of an adult bike 36 spokes. Divide by 4 - it turns out 9 knitting needles in a row. The first bottom is baited through the 3 holes for the fourth. The second row - in the opposite direction, starting from the middle empty hole, and then in all the middle ones. The third row - in one direction with the second in the free along the hole. The fourth is the same as the first.
After knitting, evenly tighten all the needles nipples until they lightly touch the rim. With the help of such a device and a welding machine, a rugged wheel can be manufactured, for example, for a wheelbarrow.

All about the foundation on stilts
There are several types of concrete bases, which are chosen depending on the design and type of soil. One of them is svayorostverkovy foundation.
+ Excellent stability and high bearing capacity. This plus plays an important role in the construction of buildings on soils prone to movement.
+ Ideal for small structures on complex soils.
+ Cheap and prefabricated foundation type.
+ Due to the lack of soil contact with the grillage, rodents will not fall into the house.
+ You can build a foundation without the involvement of powerful construction equipment.
+ No need to pre-clean the construction site and level the surface.
+ This base is suitable for buildings made of aerated concrete, brick or wood.
- It cannot be used for massive and heavy construction.
- Due to the presence of free space between the floor and the surface, it is necessary to insulate the structure.
- Difficulties in repairing existing grounds - it is necessary to build retaining walls or to install additional piles.
