Homemade machines

Drill and hand drill


Drill - DPR-52 engine, found in printers and hair dryers. A hand drill is a motor from a car compressor, found in small heat guns and hair dryers.

 
Drill 2


Drill with replaceable tips. Motor PIV MTM, from the tape drive of a vertical tape recorder, Bulgarian. The tachometer is removed, and a flexible shaft of the drill is fixed in its place. Rotation from the motor axis is transmitted to the shaft using a tightly fitted spring. On the right side of the axis there is a diamond disk for dressing burs. The entire mechanism is fixed in a holder with two degrees of freedom and easily rotates left and right, back and forth. The entire structure is suspended on the desktop at the top right and does not interfere with work. You can recess the motor into the table so that the drill hose extends vertically upward.

 
Engraving drill


Drill for engraving work. The motor runs at 8,000 rpm, the hose endures up to 10,000 rpm. The motor and hose are connected by a spring placed on the axle.

 
Drill 1


Handle with a mechanism from a pneumatic drill. The motor transmits rotation to the turbine, mounted through an adapter ring. The drill body already contains a planetary gearbox of approximately 3:1. A very powerful machine. Turning work was required: an adapter ring, a bushing on the shaft, and adjustment of the Morse taper to size 2a.It was difficult to install the high current button.

 
Drill 2


Motor PIV 6 25/3A made in Bulgaria, operates from 5 to 40 V, from a vertical tape recorder/drive. The tachometer (rear) is not used, but balances the entire structure well. The button acts on the contact group from the iron, is powerful and does not burn.

 
Cutting machine 1


Cutting machine 1 is made for unreinforced abrasive discs with a thickness of 0.5-2 mm. Movable table. The "braking" resistor is visible.

Cutting machine 2


Cutting machine 2 is made for unreinforced abrasive discs with a thickness of 0.5-2 mm. Two working positions, from the upper and lower tables, so the motor is in reverse. I cut boards, make keys, cut out frames for transformers.

 
Drilling machine 1


Drilling machine with 0.8 mm collet chuck. Made from the remains of a mechanism called an "aluminum tag press". Engine DPR-52, I lengthened the axle only for the beauty of the whole structure. Drill stroke - 20 mm. A box for drills and an abrasive disk on the axis of the engine at the top for straightening drills are visible.

 
Sanding machine 2


Burnishing machine chambered for 2a. The stand is made of aluminum profile and contains a worm gear; with its help, the carriage on bearings moves 80 mm for drills of different lengths. The handle itself moves the motor another 20 mm. At the top of the motor axis is an abrasive disc for finishing drills, protected by a frame. The motor is Bulgarian, from a tape recorder, the profile is from a display case, the worm is from a water valve, the bearings are from a retractable table.

 
Sanding machine 3


It's just a beautiful machine. The basis is a frame for linear movement of the heads of an 8-inch drive. On six bearings. The cartridge is fixed in the sleeve from the fan of the same drive.Worm gear - from a 5-inch floppy, round handle at the top. The last 20 mm of the drill stroke is done with a separate handle. The transmission from the motor is a rubber belt, but a flat belt is better. I'll make the engine stronger.

 
Sanding machine 4


Drill from a microscope. One screw moves the table for drills of different lengths, the second was damaged, so the last 20 mm of travel was made on it, the rods, spring and handle are visible. Engine DPR-74. Under the table there is a drawer for drills.

 
Lathe


Wood lathe. Motor PIK 12-3/10.1 from a Bulgarian tape recorder/drive. Polish cartridge, up to 150 mm. Right headstock with rotating center and 20 mm feed. The support is fixed and moves horizontally. I use it to sharpen file handles, small things like salt shakers and buttons. The caliper turned out to be weak, vibrates on hard wood, I will redo it.
