Where do you puy the water and how much.

Most of the time I use the wet wheel to recover a dulled edge on a tool as I use the tool. The dry wheel is better for major redoing of an edge that has sustained nicks or needs to be ground at a different angle. The setting of the tool rest is not as straightforward as it could be. There are no setting marks and no instructions. The problem is that the height and angle adjustment have to interact to get the plane of the tool to be sharpened so that it just kisses the flat wheel along its length. This seems to be best done by adjusting the angle of the rest to the angle the tool is and then lowering the rest gradually until the wheel is just touching it. It seems that it takes a couple of tries to get it right. The flat wet wheel is fairly soft and can be grooved easily. Once the tool rest is set, a couple of passes will get it smooth. Sometimes, the rest must be lowered slightly once or twice to get the edge really sharp. This can be determined by the presence of a slight burr on the side of the edge opposite the side being sharpened. Since most edges are flat on one side and angled on the other to make the edge, the final action is to remove the tool holder and slide the flat side over the wheel to remove the burr. Once the angle is set, it will work for both the wet wheel and the dry wheel. If you need to do more grinding than makes sense on the wet wheel, you can start on the dry wheel and then move the tool rest to the wet wheel, only needing to adjust the height. The tool holder works well with chisels and plane blades. It can handle the blades for my 6" jointer. It works fine with skew chisels. For other lathe or carving tools, it seems to be better to use just the tool rest to steady the tool and maneuver the tool by hand. This works well for gouges and parting tools. The water is a little messy. You put water in the tank with the knob turned to prevent dripping. The drip spout on the tank should be positioned to be near the center of the wheel so centrifugal force will pull it over the wheel. A drain spout is located on the bottom of the wheel guard and a receptacle must be placed under it to catch the runoff. The knob is adjusted for a slow drip. General Impressions The tool is built to the top quality that users of Delta have come to expect. Parts such as replacement grinding wheels are readily available. On the positive side, having the capability of making flat angles is nice. The wet wheel is much safer when honing fine edges that can easily be damaged by the heat of dry grinding. The dry grinding wheel has a pretty small diameter for grinding in the traditional way, making a pretty deep concave angle, but the ability to grind along the top is good. The lack of a light is an obvious disadvantage, less so with the flat wheel, of course. The weight of the machine makes it pretty stable and vibration from the induction motor and drive train is minimal. Having never used such a tool before, I found the lack of information in the owner's manual to be irritating. Luckily, good internet access can do much to overcome the learning curve.
