  1. Interesting. In 28 years of making pots I've never greased the bearings on an electric wheel. They're usually sealed and need no lubrication. If there is a way to grease it, then I would expect there to be a grease fitting somewhere on the bearing block.
  2. @Rita Mattson Are you sieving your glaze when you mix it? I see a lot of chunks in it.
  3. @Rita Mattson You can make any glaze brushable by substituting some of the water with gum solution. So first find a glaze that fits your clay body. If you're just using the clear as a top coat over the whole pot, I strongly recommend just dipping it, as it is much faster and easier to get an even application than brushing. Gum solution: Mix 2 tablespoons CMC gum and 1/2 teaspoon copper carbonate (preservative, won't affect glaze color) with 1 gallon of hot water. Mix and let set overnight. Then mix it well using a hand blender. Then when you make your glaze, substitute the gum solution fo
  4. Plaster molds are not typically made directly from the wax original. I would consider making a silicone rubber mold from your wax original, then make a plaster model from that, and then make your plaster mold from that. It's a couple of extra steps, but you'll avoid the problem of the wax softening and get a better looking piece in the end. Plus you'll have a rubber master mold that you can make more plaster molds from in the future.
  5. Looks like shivering to me. The shape of the chip on the left end is exactly how I would expect shivering to look. Plus shivering is most commonly seen on the lip, and most commonly seen with low fire white bodies.
  6. Trying to replace specific broken bricks in a slab is not a good idea. First, you'd have to get the old bricks out without breaking any other bricks. Then you'd have to clean off any old mortar from the bricks, which would be just about impossible. And even then the old bricks won't take mortar very well and the joints would likely fail fairly quickly. You've got 4 options to fix this: 1. If the floor is in good condition, swap it with the lid. Put a piece of sheet metal on top of the kiln stand to support the cracked slab. 2. Build your own lid with bricks and mortar. It's messy, an
  7. Pin it for now if you can get it to hold, then replace the bricks when it's time for new elements. If pins won't hold it, then order new bricks from Evenheat. I'd try taking the old bricks out before ordering, in case you break the element and need to order a replacement. Sometimes you can get bricks out without hurting the elements, sometimes you can't. It all depends on how old and brittle the element is.
  8. Dirtballs said "Now what I want to do is pull my retirement funds and build a new house, studio, all the equipment, newer Nissan NV 200, and still have enough cash to live for a year and a half".
  9. If you plan to fire to cone 6, you want a kiln that will at least get to cone 8, ideally cone 10. Otherwise you'll only get about 30 firings before you have to change the elements. I'd call Olympic, as they will be able to give you some info about this kiln and make recommendations about increasing the cone rating, possibly with just new elements, possibly with taking out the blank ring.
  10. Hard to say without a picture. Try emailing the pictures to yourself and see if it gives you the option to resize them. Otherwise, there are numerous apps out there that can be used to resize. Or do you have a link to a picture?
  11. The motor on the kick wheel does not have much control. It's just a full speed motor pushing against the fly wheel. Not a lot of good reasons to get a kick wheel unless you really love them. Plus that Lockerbie is a nightmare to move.
  12. If you have a sitter, you just need small cones or bars for that, and you don't really need to use the larger cones on the shelf unless you're calibrating the sitter.
  13. @Millkeabe If you haven't used a kick wheel, and don't totally love kick wheels, get the electric. What's the price?
  14. My kilns definitely heat my studio when they run. I don't vent the heat out. Nothing better than running the big kiln on cold winter days. It can replace the regular heating system for a day or two. And I don't have air conditioning, so I'm not fighting to cool that heat in the warmer months, I just open the overhead door and let nature do it for me.
  15. In addition to the impact being very small, there's also just not a lot of us. If everyone in the world had a kiln the way we all have cars, then there would likely be more rules about dealing with kiln emissions. As it currently stands, the issue is the air quality in the kiln room, and venting properly to make it a safe environment for us, not preventing those fumes from entering the outside environment. I suppose that if the EPA really wanted to hammer down on us with the same rules as large commercial enterprises they could, but it would be difficult to justify the cost and effort for such
  16. It can't be removed, but it can be cleaned. You just pop the wheel head off and scoop it out. The benefit of that design is that the wheel is heavier so it doesn't move when centering large pots, and the pan is super solid so you can brace against it if needed. They're not at all difficult to clean, you just grab a big sponge and scoop it into a bucket. Many of my students prefer the built-in pan to the removable. If it's you're own personal wheel, you don't have to clean it spotless every time you use it, anyway. Either way, like GEP said, it holds a ton of trimmings so they don't end up on t
  17. Someday they'll require catalytic converters, but that'll double the price of the mower. I feel really bad because I'm still using an old 2 stroke engine. I keep hoping it'll die, but it won't. My dream mower is an 80 volt cordless electric self propelled.
  18. A friend of mine did a study on the ecological impact of salt firing, and found that he could fire the kiln every week and use something like 25 pounds of salt in every firing and it would pollute less than driving his car. I would worry more about your lawnmower than your kiln in terms of ecological impact: The EPA estimates that hour-for-hour, gasoline powered lawn mowers produce 11 times as much pollution as a new car. Even refilling lawnmowers damages the environment. It is estimated that 17 million gallons of gas are spilled annually while refilling lawn mowers. In contrast, th
  19. Metal shelving for kiln furniture. You can make your own rolling stand for a small kiln pretty easily. Two layers of 3/4" plywood, glued and screwed, topped by two layers of cement board, 4 casters. Be sure to get casters that can sit for long periods without denting, so hard rubber, plastic, or metal.
  20. The 1/3hp Skutt wheels are plenty powerful for most people, but the upgrade to 1/2hp isn't much more expensive. I've got ten 1/3hp wheels, one 1/2hp, and I've never felt like I needed the extra power of the 1/2. I've thrown a lot of 15-25 pound pots on the 1/3hp without any issues, and made many 45 pound pots on them in sections. I prefer the built in pan, too.
  21. Don't get a 'beginner' wheel. They last 30 years or more, so get a good one. For Brent that means a C or CXC. For Skutt, anything with 1/3 or 1/2 horsepower. Not sure with Bailey, but anything that's higher end. Invest now and you won't have to invest again. FYI, big splash pans keep the studio a lot cleaner.
  22. You'll have to get an electrician in to check out your system and see what will work.
