I bought a WEN 4280 5 Amp 8" Variable Speed Bench Grinder with Work Light and WEN 4288 Cast Iron Bench Grinder Pedestal Stand with Water Pot. There are four changes Wen could make to change this from a four star to a five star rating. 1) This grinder should be compatible with the stand. Second best solution, clearly state that it is not compatible. The stand came with four 8mm installation bolts. The grinder only has room for two. I spent a great deal of time trying to figure this out. I added two 3/8 inch clearance holes 9 15/16th inch apart. This was a tad high, maybe it makes more sense in metric like 252mm or something. My DeWalt Cobalt (metal) drill bits drilled right through the base no problem. See picture of the stand base with 2 extra holes. See picture of grinder with two 8mm bolts in these holes. Extra credit suggestion, change the distance to 254mm (10 inches, stand and grinder) and make life easy for everyone. 2) The very first instruction, Instruction 1 (page 8) mentions a “hex head screw (Fig. A-3)”. Instruction 4 (Spark Arrestor and Eye Shield) calls a similar item “lock knob (Fig. B-6)” which makes much more sense. It wastes a great deal of time to decide the instructions are wrong. 3) Given the title of this item it should include a bulb for the Work Light. This is a high vibration machine and an ordinary bulb is likely to fail quickly. Second best solution, clearly label “NO BULB” and recommend a specific bulb. 4) There is no storage clip for the drill bit sharpening plate. Second best solution, put a hole in it and add a hook. Observation: The right and left eye shields are so symmetrical I installed them wrong, even though I spent time trying to avoid this very mistake. Label them L, R or 1,2 if they need to be installed as shown in the front picture. If I was standing next to my assembled machine I could setup another one in ten minutes (without fixing the hole problem). So maybe it’s all no big deal in the grand scheme of things.

It works better than I thought. This is the first time buying one of these so wasn’t sure what to expect. All the other ones I have used are really old.
I bought this mainly for repairing and making throwing knives. The two different stones are perfect for the task. The variable speed is also great and makes it much easier as I prefer to keep the speed lower for sharpening. The light and all the other features it comes with just add to it.
The 8” size is bigger than what I really need but don’t regret it at all. Very solidly built and very smooth running.
