How to make a real drill press, bench top drill machine making, motor speed setting, pulley diameter setting, this video is a follow-up video of the bench top drill machine making video I shared earlier on the channel, many friends in the comments said that the era was fast, so I used a new pulley, the diameter of the pulley connected to the motor before, 100 mm, the pulley connected to the shaft 200 mm, the speed of the motor rotates at 1400 revolutions per minute, when we use 200 mm and 100 mm pulley, we get 700 revolutions per minute, this is for a drill. In thick metal drills, it causes the drill bit to burn, most importantly, it causes the engine to be forced, but when we reduce the pulley connected to the motor from 100 mm to 60 mm, we get a rotating speed with 420 revolutions, so the drill bits do not burn, the motor is not forced, on the contrary, it is more powerful. I drilled a mm thick heat treated, in 10% steel metal, also made a few changes to the machine, I hope you like it.
