What can be made from the gearbox of an angle grinder

DIY from an old angle grinder

What kind of do-it-yourself out of the old angle grinder can be done yet?? For example, you can easily construct a grinder on rollers, which is very convenient to use. To make a grinding machine from an angle grinder, you will need two narrow strips of metal, a stud with a diameter of 8-10 mm, washers and nuts.

In the photo homemade grinding machine can be seen that the bottom metal strips are fixed two rollers or bearings, which allow easy movement of the grinder along the workpiece. In this case, the angle grinder is attached to the strips of metal with a stud, which actually can adjust the height of the angle grinder over the workpiece.

It’s easy enough to make from an angle grinder and homemade as a garden mower. For these purposes it will be necessary to use an old wheelbarrow, bottom of which is placed an angle grinder with blades or a line for mowing grass. The only disadvantage of this home-made from the angle grinder will be that to connect the power tool will need to use a fairly long carrying. In that case, it is much better and more convenient to use an old cordless electric screwdriver.

What you can make from an old angle grinder still? Here’s a small-sized circle cutter or, for example, a belt Grinder like the one pictured here. You need to take two square pipes of different diameters, in the one that is larger, insert a spring to tension the band. The shaft of the homemade grinder from the angle grinder is made of wood with an inserted nut inside to fix the shaft to the angle grinder.

You can make from the angle grinder and a machine for sharpening spiral drills, as well as, a full-fledged circular saw. It should be noted that the design of circular saws from the angle grinder can be very different. The pictures below show perhaps the simplest version of a circular saw.

It will not be difficult to make out of the angle grinder schtroborez, but will have to work hard in advance to install 3-4 disks (depending on the desired width of the ream) on the shaft of the angle grinder.

Сool idea for a vacation from an old angle grinder!!

Slipping Gears

On the description and correction of this failure I will dwell in more detail, because its elimination will help avoid other failures.

There is always a temptation not to buy new pinions, but to use the old ones, even if they are worn a bit, but not completely worn out. Unfortunately, nothing worthwhile will come of this endeavor. Waste of time and effort. Once rolled up edges of gears can not be restored, they will in any case slip.

If the process of teeth wear has gone too far, the angle grinder when you turn on it emits a characteristic whistling sound. The gears in this case have to be replaced, and in pairs. One can visually judge how worn the gears are. On one side of the teeth of both gears a characteristic radius is formed, smoothly turning into a chamfer, formed by slippage of the mating gears.

Why This Malfunction Occurs

  • In my opinion, the main reason is inaccurate design calculations of gearbox dimensions, everything is done on the spot. Next, escalating, the lack of technological discipline and as a consequence, defects or short life of the tool.
  • Another reason is the discrepancy of materials. If someone is engaged in repair of Chinese products, he understands what I mean.
  • Loose fastening of the gearbox cover. The cause of this malfunction is more likely carelessness of the user, the power tool should be watched, but it may turn out that in one of the fasteners of the cover to the housing elementary threads are broken.

How to fix this problem

Of course, you will have to change pinions in any case, but the tool’s performance after repair will not last long. The cause of the problem should be eliminated.

There are four ways to repair an angle grinder suffering from insufficient clutching of the drive and idler gears.

  • Grind approx. 1 mm of the gearbox housing metal surface adjacent to the cover or grind half of this distance on the housing and the other half on the cover. This method, only at first sight, seems the simplest of all suggested. In fact, without a surface grinding machine it is hardly feasible, at a more or less quality level. over, when grinding the housing the depth of blind holes for fixing screws will be reduced, and this can affect the proper pressing of the cover to the gearbox housing.
  • Shift the pinion (small) closer to the idler using a shim washer. In principle, this method is not worse than the next two, but here the problem is to calculate the size by which the pinion should be shifted. Insufficient contact won’t do anything and too close contact will only speed up the wear process.
  • Shrink the driven gear on the shaft from the cover bearing closer to the driven gear, about 1 mm. The idea is simple, a tighter fit is prevented by the retaining ring, which, in turn, is held in the retaining groove machined on the shaft. That’s why you need to make a new groove, below the native one, about a millimeter, and put a washer, which thickness is equal to the distance by which the locking groove is shifted, under the pinion.
  • Center the shaft with the idler bearing on it. To do this, turn the bearing shoulder on the shaft. At the same time the shaft will be somewhat displaced to the side of the cover (in my case by 1.3 mm). The idler pinion will be displaced together with the lathe.

Turning the shaft is probably the easiest and most effective solution to the problem of insufficient clutch of the gears, of course, when you have a lathe “at hand”. If necessary, you can also cut the end of the shaft, which enters the support sleeve.

This is what I meant when I wrote about material mismatches. As you can see, the sleeve is made of powder, but worse than that, this powder is not properly sintered and means that the part will soon just fall apart.

Some grinder models have a needle bearing instead of a bushing, which, however, does not really affect the life of the product as a whole.

Grinder for making it with your own hands

Various accessories for angle grinder allow you to expand the functionality of the tool and make it convenient.

  • Grain grinder.
  • Lathe.
  • Knife sharpener.
  • Powerful drill.
  • Tape Grinder.
  • Fitting saw.
  • Home mini-pilot grinder.
  • Milling machine.

Router

Indispensable tool for woodworking. Professional models are expensive, and the milling machine itself is not required too often. But it is possible to make a machine tool from an angle grinder, which is not inferior to the factory one. To do this, you need:

  • Purchase a chuck for a drill with M14 thread or make it yourself.
  • Mount it on the angle grinder instead of clamping nuts.
  • Assemble the base. It is important that there should be a tool height adjustment. two guides with the ability to fix the angle grinder.

For the materials we choose what we have on hand. For working with wood, a machine made of plywood will do. The plane of the base must be as flat as possible, otherwise it will be difficult to achieve a good quality of processing.

If you want to make a collet chuck for cutters from a magazine, it is also possible. Masters often use homemade tooling made of copper and bronze.

When making a milling machine, keep in mind that the angle grinder was not designed to work with long shafts and nozzles, so backlash may occur when installing chucks.
