The grinder would be easy for anyone who uses tools to assemble .The grinder is an excellent tool for general light to medium grinding.. Sits solidly on the bench with no movement even when not bolted to the table. The vibration is minimal and typical of good grinder. I have never seen a grinder run perfectly smooth from small to the industrial grinders I have used. One point about complaints regarding vibration. Dress the grinding wheels with a good grinding wheel dresser as the wheels wear down. . Out of round grinding wheels are the usual cause. of excessive vibration I use this grinder for fine dressing of tools, drill bits, using a fixture against the wheel to sharpen them as well as other medium to fine grinding. This grinder works perfectly light grinding. It is not a heavy duty machine but fine for general home and light to medium use around the shop. The grinder does take a about 15 seconds to fully turn on. It does coast after turn of for close to a minute. A light touch on the wheel with a piece of metal will stop it quicker. This isn't an industrial grade grinder with a inertia brake to stop the spin when turned off, very few light duty home grinders do. include that feature. The eye shields are made cheap but work OK. Someone might want to replace them with heavier eye shields.
