    Hulk got a reaction from Genboomxer in kiln help   
    Hi Kiki!
    I have a KM-1027 (with 3 inch brick); it holds a lot, is still supported (it's over 30 years old; Skutt answers the phone - they're great!), and didn't break the bank. On the other hand, auto control would be nice, it does take up a lot of room, and isn't cheap to run. All in all, it was a good choice for me. At this point, looks like I'll choose the same size if/when the time comes, just add a controller; more likely I'll build a controller to add on, for I don't see anything to go wrong other than element replacement.
    As for a mentor, might be hard to find! I'm still new to ceramics - coming up will be two years - this forum has been very helpful, also two semesters at the local JC, many books, articles, and You Tube. There are many potters in our area, however, haven't made any bff relationships just yet ...the instructor and students at the JC were great to be with and around - good experience for me.
    Any road, take your time! Home studio - easy to keep clean, lots of storage/shelving (I built on the walls, mostly - leaves the floor clear), lots of counter, logical workflow, music, warm/cool, clean, did I say clean? :O Uh-oh, better mop today! Good ventilation, especially kiln fumes...

    The You Tube vids might get you started. There's a box of Plainsman and a bat rack in the background - looks like a studio! - and it's fairly clean, good sign there. The tools required are indicated. Looks like the tech is fairly handy, however, likely has not performed this repair enough times for it to have become rote; it's a start, eh?
    There's some helpful notes in the comments. The bearings listed should be easy to get; hold out for abec-5 (fwiw, I find abec-5 hold up longer over abec-3 in bicycle hubs...).
    I put new bearings in the freezer to shrink them a little, and the part receiving the bearing in the sun or some other warm place. I have a threaded bearing press and drifts, hence no hammering on new bearings; for cases where my press won't fit, a drift that makes contact with the outer race is what I want, and gentle taps on said drift, not the bearing, ahem. Watch that the bearing stays square inna hole! Grease both the bearing and the part against next time (another use for Dow #41 Bill!); I also treat all threaded fasteners with anti-sieze; it's a habit.

    Hulk got a reaction from Rae Reich in Kiln never got to cone 6, should I wait longer?   
    Hi Good!
    If/when you look at getting more shelving, may I recommend half shelves - more flexibility? Staggering (different heights) the upper levels gives me more even heating; my top level was running too cool with the shelves levelled up.
    Other suggestion I'd like to offer: monitor firing temperature, which you can do if your cone packs are visible through the peep holes (wear appropriate eye protection!!). I also use a pyrometer, which is very handy for slowing down through critical temperature ranges, note taking, etc.
    For glaze firing, I bump up to about 200F the night before, turn all off, then go straight to High the next morning - everything is still warm, and also bone dry; no Low or Medium until the brief hold after reaching peak temp. Bisque fire requires much more attention...

    Aye on the moly! I've a few tubes of Dow Corning 41 grease, which contains "Molykote" - great for lots of things, particularly rubbed into cables where they run in housings, also derailleur spools and pawls, freewheel pawls, pedal bushings...  The dry powder is great for lots of things too, e.g. a puff in lock mechanisms (doesn't gum up the works, nor attract dirt), a tablespoon or so blown into an old cranky transmission (where the tolerances are quite a bit greater than the particle size)...

    Hulk reacted to LeeU in Potter/ceramicist: Pottery/ceramics?   
    I have always preferred ceramist, when I have to choose, because it is rooted in the 10,000 BCE/BC  years of humans making thing of clay. It is simple and to the point.  However, the word is not terribly familiar to the general public, compared to, for example, potter. I have also used clay artist, as a more contemporary term. I like that it is vague enough, without being as mysterious as ceramist (or ceramicist), to not paint me into a corner, such as "potter" would.   
    "Title(s)" seems synthetic to me. The terms we use to identify ourselves as people who work in clay,  to my mind, are  just descriptors that serve the purpose of providing others with an approachable entry point to our activity and output.   A title for what we do, which is likely to be commingled with "who" we are, is fairly essential for communication and interaction in today's markets, whether as a hobby or as a career/profession, whether for profit or not, and even whether inferior or of exquisite quality.

    Okay, just started my class at the art center and my wonderful teacher, sculptor Linda Lewis, here in Des Moines, scolded me as she asked if I pre-heated. Um, no mam. Crap. But then she told a story of a thing she fired for a student with a 12 hour pre-heat and it blasted out a side. Lesson for me now, just slow down and let them dry for a month. Poke holes. hollow out, in the end, it will result in a more quality piece anyway.

    Just thought I should check this  to confirm my thoughts on the gearbox drive and  ...... since @Hulk mentioned google and Venco (genius!) I highlighted a part of the venco manual that reflects the gearbox oil  drain plug and procedure to drain and fill. Something you could check to make sure they are not loose and also can check the current level.

    What's on my workbench? Nothing.  There is no worktable at the moment. Up until today--2 days before, 1 day of, and 3 days after the non-even craft fair, it was not available.   It has finally made it into the studio now, though half of the bins of the pieces are still in the trunk. The little sidewalk fair was fun-ish, at least talking with the other vendors who weren't selling anything either (no traffic). Not so great for the back/hip, so in the future I'll only be participating in venues that provide tables, however few that may be. And, DUH, I can't do anything, really, without my work table actually being in the studio, so there's that lost time as well!  Maybe tomorrow I can get up the steam to put my work space back together.   Updated, the last 2 pics-a day later- got my table back up, yay me for not procrastinating and laying about all day watching Nothing Gold Can Stay--an addictive Amazon series, just FYI.

    This is a kiln that requires a neutral wire and a ground. It is 3600 watts and should easily work on a 30 amp 2 pole 240 volt breaker. I would make sure this is wired correctly as it is a bit unusual and wired incorrectly will have unexpected results. Changing a 30 amp breaker to a 50 amp while leaving 30 amp wiring in place is a fundamental flawed idea in my opinion.  I would have this double checked before operating this kiln again.

    Yikes, the 50 amp label on the kilnsitter just means it can be used on kilns up to 50amps, it's not how much it pulls.  It needs to go onto a 25 or 30 amp circuit with appropriately sized wire.  Putting a 20 amp appliance on a 50 amp breaker is a recipe for a house fire, especially if that 20 amp appliance has been tripping a 30 amp breaker!
    I'd maybe find a different electrician if that was his solution, always follow the manufacturers specifications!

    Hi Martin!
    Kiln vents I've seen or read about exert enough "pull" on small hole(s) in the kiln (kiln bottom, or side near the bottom) such that another small hole (in the lid) is necessary for make up air; the rest of the flow comes from ambient, through a mixing box, where the ambient vent is adjustable. The kiln atmosphere is very hot and typically corrosive, hence mixing with ambient is a good idea - cools it down and dilutes the yucky gases.
    Perhaps these pics may help? They show flow through aforementioned inlet and outlet holes (however, in practice, air may be sucked in through cracks, around the edges, etc. ...and some kiln atmosphere may escape as well) and ambient making up most of the flow - see "Room Temp Air Entering Bypass Box"
    Any road, immediately diluting the kiln atmosphere is a must (imo)!!
    There must be sufficient make up in the kiln area/room as well - to (easily) make up for all the air being pulled out of the room by your fan system(s).
    Test the flow with a smoke punk (incense stick will work) or lighter flame (careful with that!) - so you can see that atmosphere is sucked into the kiln; re-test when firing, as the behavior will be a bit different.
    I made up a bypass box out of galvanized sheet, bought an inline fan and some ducting, and made holes in the wall and kiln -it works! If I were starting over, I'd go with a bigger/stronger fan.
     
    60 liters, hmm... less than three cubic feet; your fan may be strong enough to serve your current kiln and your next kiln as well!
    The "bypass box" with sufficiently large and adjustable ambient vent - that's the ticket.

    Hulk is correct. Kiln vents pull a small amount of air from the kiln, and mix it with a large amount of air from the room, so the air going through the system is below 150F. I would contact the kiln manufacturer and see what they recommend for use with their attachment.

    Well, the deed is done. It was a non-event. The morning hours carried serious threats of rain-there was heavy competition from many other fairs and events statewide that weekend, and no signage (??!!) even at the entrance to the site. Nobody sold anything--literally (well, one vendor sold a $5 item-seriously-that was it!). 
    Without knowing what I did over the weekend (organizing & packing up all that stuff, schlepping 3 tables and all the wares & display props out of the studio & into the car-unloading-setting up-breaking it down, re-packing, more schlepping, unpacking, etc. etc. and half of it was still in the back seat Tues.), on Monday my chiropractor told me that whatever it was, not to do it again! Took 3 times the usual adjustments to get me straight!  
    I have decided that the only events I will do--if I do any at all--are those where they provide the tables! 
    I think my low-budget set-up looked decent, tho.

    Wherever that oil came from, it ain' there anymore, hence, suggest you don't run it until the seepage has been corrected and the you're sure that the machine is properly lubricated - the reservoir of origin being filled per specification.

    Looks like gearbox oil. And looks excessive in the picture, I would send the company a picture and restate your concerns. I don’t know this machine but the drive in the picture likely is a planetary arrangement which should require lubrication and have a front and rear seal to contain heavy oil or grease. Just a guess but I believe this is quite excessive.
