Review on πŸ”§ Efficient 4 Inch Compound at Hardware Factory Store: Enhance Your Hardware Tasks by David Monaco

Revainrating 1 out of 5

Poor design

1. Main screw not centered for upward movement. As the top moves closer to the center, where the top moves closer to the bottom (form) nut, the displacement of the top main screw makes it more angled from the centerline, and therefore the top movement cannot be moved safely. further towards the center, although there is a distance. Better stop the movement of the top in a safe place, not too close to the center, otherwise the top casting nut will be permanently damaged because the displacement is more noticeable at close range. I had to increase the wood spacer between the upper jaws to hold something just below the drill bit.2. Bottom alignment is another bad story. A cast bottom nut is a pin that doesn't really have enough metal in its cubic size. I don't know why they couldn't make a big cube out of it. A small cube nut is screwed in near one side of the cube to correct center alignment here as well. The cubic nut attaches to the upper deck with only one pin in the socket, and that pin dangles so freely in the socket itself. If you're trying to refit and remove and reinsert everything, then note the direction of the cube nut in the Rifle. It is off center and if you place the cube nut wrong it will cause more and more misalignment.3. The bottom main screw also has some rotational play before it starts moving in one direction or the other. The problem of center offset is also present with this screw/cubic nut. That's probably why this cubic nut pin stays in the socket so loosely that it doesn't break when the user moves the misaligned main bolts. A jaw holding an object is a different story. The fixed jaw does not approach the center where the drill enters. So if you really want to drill something small, you're out of luck unless you enlarge the gap with some extra material along with the object to keep the object under the drill bit. Tightening the top screw applies resistance on one side with each turn of the handle. This means that the main screw of the upper part is bent. This is very noticeable when we look at the crank holding the baseplate as we turn the crank. The handle and main screw rotate eccentrically, indicating that the main screw is bent relative to the cast nut.6. The upper drive handle starts hitting the bottom friction adjustment screws as the top nears center. They used friction screws that were longer than necessary. Shorter screws might prevent this, but before that they need to correct the misalignment first to get the top any closer to the center at all.7. The packaging is absolutely stupid. I don't know why they're trying to keep thermocarbon matter. The product was packed diagonally with the main main screw almost touching the thin sheet metal of the packing box itself. There is only about 1/2mm of thermokaol in the corner. and that's where the grip screw ends. The one I received was already cornered hard and the end of the main bolt where it becomes the grip bolt was already damaged on the grip bolt threads. I had to re-tap that part of the main bolt to fit the handle and nut. They had to rethink their design. Need to reposition the casting nut for proper alignment, make appropriate corrections to the center alignment handle holder plate, increase the cube volume of the casting nut for the bottom nut, increase the quality control of the main screw bends, increase the size of packaging material and carton. Castings from the top and bottom weren't enough.

Pros
  • Drills
Cons
  • Questionable purchase for the elderly
