Grinder is a grinding machine used for final machining. Represents a wide sanding belt, rotating on the shafts by an electric motor. The most widely used grinder in knife making, tool sharpening. Grinder allows most exactly and at the correct angle sharpening of the cutting edge, and also prevents overheating of the material and loss of metal properties.
Today we will show you how to make this machine, again, which is done manually it is not only saving your money, and in order to make it build for your needs and the specifics of production.

Instructions for making grinder from grinders with their hands
So, start with the fact that mark material for cutting grinder parts frame our grinder and other details. Then from the old angle cut using the grinder detail that will serve as the sole part which will abut the rear portion of the sanding belt when pressing on it.
After working with svarochnik get a kind of frame.
In the ever-spot weld the nut and steel strip, do the moving element of our stanochek.
Then sawn off at an angle to the steel belt, screwed in the nut, on the edge of the frame. From the sawed off piece of steel make a rectangle that will serve as the focus of our steel strip.
Using a screwdriver, grinders and taps make the hinge part.
Hang the spring on our moving steel strip.
From steel strips cut two rectangular plates and drill them in the 2 holes at the edges, it could be the brackets of the machine.
Next, fasten big bolts and sole in the prepared in advance, they serve as axes of rotation of the shafts of the machine. Cut an aluminium sleeve according to the size and inserted into selected segments of the sleeve bearings, then placed on the bolts.
Pay attention to the fact that the hinge element is needed for angle adjustment of the rotating sanding belt. Adjust the tilt using the screwing or unscrewing of the thrust bolt. It is registered so:
Further, from the steel strips make a kind of bracket under GRINDERS
and the bracket on which it will move along with angle GRINDERS.
On the main frame weld two bolts after fitting, it will slide to the above design.
They screw the nuts contribui and install the washers.
Next, attach the bracket angle GRINDERS are the long-bodied nuts.
Secure our LBM on the bracket and screw on its axis prepared from the aluminum liner of the shaft.
Finally, put the sanding belt. Check the course. Run and adjust the incline.
But that’s not all! Make of steel strip is a box, which will serve as a bracket for the fence.
Fasten it to the bracket on the underside of the machine.
Further produce thrust bar and fasten to the bracket.
And finally, our GRINDER is ready!
Grind small parts, sharpen knives and home-made instruments, but do not forget to secure the grinder on the work surface! Wish you success in all your endeavors!
