  1. I would think that you have to determine how high on the hog you want to live, what your sales outlets might be and what the cost of electricity is in your neck of the woods...
  2. Welcome to the Forum, Mermaid...Your cost per firing depends on your cost for electricity per kilowatt -hour. If you were to run the kiln at full power for 9 hours at 20 cents per Kw-hr, it would cost about $11. You won't be doing that because your firing schedule is a gradual build-up to full power. 25 amps x 240 volts = 6000 watts = 6Kw x 9hours =54KW-hrs x$.20=$10,80. The 30 amp breaker should be adequate. You might be able to get a user's manual from Cress where you will find their instructions for operating the kiln manually. Hope this helps and good luck on your journey into the mud! JohnnyK
  3. Extrude it... Each of these bud vases utilize tubes at 5", 7", and 8" at1.2" diameter. I can go to 2.5" diameter and as long as I want. The wall thickness is 1/4"on these which I think is a tad thick, so the next batch will have 1/8"-3/16" walls...
  4. If it's OK for the hat to stick to the snowman's head, definitely glaze the contact area, fire them together and the hat glaze should melt to the head glaze and you'll have a one-piece snowman/hat combo... JohnnyK
  5. I got tired of fishing around in a plastic bag full of holders, so I made a simple Holder holder to hold my holders.

    Repairing greenware

    Just last week I picked up a leather hard bowl by the edge and broke a piece off. my choices were: trash it; trim it down to half its size: or break the rest of the edge of the bowl and call it art. I chose the last option. For grins, I'm going to Raku glaze and fire it and see who might be willing to buy it as a piece of art.

    SHIMPO wheel US voltage to NZ

    Just out of curiosity, how were you able to just plug the wheel in to an outlet? Didn't you have to use some sort of adapter to go from the wheel's 115V plug to the outlet's 230V socket? Anyway, it sounds like just one of the fuses is blown if the wheel's external green light came on when it was plugged into the transformer. I'd replace both of the fuses at the same time if that is what your plan is.

    Plaster bats for recycling clay. Newbie.

    Welcome to the Forums, Aussie John...Would I be correct in guessing that you live below the equator? If so, you should be in the summer down there and if so, your bats should dry rather rapidly compared to the Sacramento, CA area where we are at the beginning of a week of cold,rainy days. As Neil suggested, put a fan on those bats, or set them out in the sun to dry. When drying your clay, check the slabs frequently so they don't dry out too much. I'm doing exactly what you are doing with a bucket of clay sludge and trimmings (about 30 pounds worth) that has been sitting around for about 4 years with the lid on. I have 4 14" round plaster bats that I'm using to dry the clay enough to wedge. It's taking about 2 days before I can flip the slab of clay over, then another day or so before it is dry enough to wedge. Then I have to dry the bats with a fan before I can continue the process. Keep up the good work with the recycling of your previously wasted clay! JohnnyK
  9. Have you tried putting a fan blowing on low to help dry things out a little? I have similar weather conditions here in Citrus Heights, CA and found the fan helps speed up the drying process...
  10. Not my field of expertise, but I would guess that it is the different batch of slip. The warping seems to be a slump in the direction of what appears to be a large handle which is pulling the mug out of shape in that direction. I seriously doubt that it's the glaze, but more the temp that is causing the mug to soften and the weight of the handle is pulling it out of shape. As for the lack of a peep hole, if you are handy enough with a drill and a hole saw, you should be able to make your own... JohnnyK

    Electric quote seem fair?

    I would say that a major part of the problem right now is supply and demand. I live in the Sacramento, CA area and retired about 2 years ago from a very lucrative 38 years in the remodeling business, the last 28 as a general contractor. The majority of my jobs were done by bid with an eye toward accuracy in both time and materials. I was reasonably priced for my needs and generally below market with regard to the rest of the industry. As such, I never lacked for work, and at one point in time had a backlog of jobs more than 2 -3 years deep. Yes, I had customers waiting more than 2 years after accepting a bid to get the job done. In northern California over the past 3-4 years, more than 40,000 houses have burned to the ground. Many folks want to rebuild...what do you think that is going to do to supply and demand for the construction industry? I've talked to some friends about some of the prices they are paying for work of all types to be done and almost regret getting out when I did...almost. Some of the prices are ridiculous, but, with a scarcity of contractors, the prices will have a tendency to be ridiculous since they are charging what the traffic will bear...just saying...

    Simple DIY sink clay trap

    So, by keeping the openings of the u-tubes well below the level of the drain opening you are able to maintain the siphon action and retain the water in the u-tubes... I like the idea for an outdoor sink, but it obviously won't work with indoor plumbing...Thanks!
  13. Depends on what you mean by good...Last year I made a bunch of bowls for Christmas gifts. One of the recipients bought 13 bowls for giving this year. I sold some pieces at my summer veggie stand last summer. This year I made a bunch of bud vases for Christmas gifts and sold half of them. Since this is primarily a hobby, I'm making enough $$$ at this point to pay for my material expenses. I also made a donation of a trio of Horsehair Raku pots to a local PBS TV station for their annual art auction which retailed for $120 and they sold them for $350 and I got 6 minutes of air time for that. So, I would say that it was a successful year. Currently I am building inventory to sell at a couple of local farmer's markets this spring. Looking forward to that enterprise. JohnnyK

    Clear Glaze over Glaze

    Welcome to the Forum, Luis. Testing is the best way to go as Gabby says, but you should note that when you do thin coats of the PC glazes, the colors that you finish with may not be what you started with.

    Kick wheel troubles

    I went through this exact same situation a couple of years ago with a "FREE" kickwheel. The bearings were shot, so I decided to replace them. And found pillow blocks that would fit the bill. I looks like the outer housing to the bottom bearing has gone away and it was a major factor in the support of the entire assembly. The shaft has slid down a couple of inches and protrudes through the bottom of the frame. The bearing/pillow block should be up inside the frame. The heads of the carriage bolts are worn simply because they actually sat on the ground. The bearing housing was on top of the frame and probably got broken somehow and just went away. You can go to www.grainger.com and find what you need under bearings. They have a pretty good selection of what you need. JohnnyK
