To begin any pottery project you have to condition your clay before taking it to the wheel.
thi is called Wedging, its a dull tedious and labour intensive undertaking.

if the clay is too wet, you have to knead the clay onto an absorbant surface to work out the excess water.  This project builds a table for this purpose.  a wood fram surrounding a 3 inch thick hard plaster top. with a convient clay storage shelf under neath.

Step 1: building the top frames

Step Number one, building the top and leg frames.

you need three of these.

<p>Thanks for this great Instructable. I have a few thoughts that may make it easier on the next person.</p><p>#1 pottery Plaster is better for drying clay (than hydrostone) because it can absorb more water, according to an instructor (Thanks Nick Tranmer) of mine. I used about 66 pounds and still did not get all the wire covered on the bottom... no big deal. I say buy 100 pounds because it is usually a better deal that way. Nick said carefully measure and weigh the ingredients because it will result in a much stronger plaster.</p><p>I had to mix the plaster in 5 gallon buckets and was uncertain of how much I could put in so I made 3 buckets with 2 gallons of water and 22.8 pounds of pottery plaster (11.4 lbs per gallon of water). It could have worked fine with 3 gallons of water and 34.2 lbs of plaster in each of 2 buckets.</p><p>http://shop.clay-planet.com/plaster-2.aspx</p><p>I should have been much more careful to get the bottom plastic flat. I got some surprisingly deep grooves in the top surface and the plaster was too hard to shave off. I ended up pouring a thin slab on the surface to level it off and I'm not sure how strong it will be. I'm pretty confident it will work fine. Thanks again!</p>
....and now i know how to make the table too!
Awesome instructable - inspired me to follow the plans. Some feedback to others, having just finished the table.<br><br>A. 30 lbs of hydro stone is not nearly enough to pour to a depth of 3 inches. 50 lbs is not enough (calculators online for volume of hydro stone). I went with 50 (because I purchased based on 30 rec. before doing the math. Do agree hydro stone IS the way to go. Either expect much less than 3 inch depth or go with 100lbs (around here sold in 50lb increments).<br><br>B. Be careful if you use plastic sheet. I was in a rush, didn't pay attention and got wrinkles in plastic sheet (with transferred to table top. Fixed with skim coat and sanding, but a real waste of time from needless extra step).<br><br>C. If going to big box retail to purchase lumber rather than using scrap lumber, consider 2x8 or 2x6 for one top box rather than 2 boxes from 2x4. Also, big boxes don't sell 4x4 around here - 2x4 bolted together work nicely and don't take long at all to put together.<br><br>D. Chicken wire and staple gun create a fast internal support structure and won't add much to project cost.<br><br>Overall pleased with outcome and looking forward to using my new table. Thanks for the plans!
plaster is smoother and absorbs more moisture to help dessicate slip to be reworked into clay, also makes wedging easier.
why not use cement????
Am I supposed to put the screws on the inside or the outside of the top frame? Also, do I use 10 gauge soft wire or hard wire? Will braided wire work? Thanks
I have already built the table before I found this great idea. Can I fill it from the top? Would it have enough air flow to dry and does it need to be super level?<br />
you can fill it from the top, but you will have to have a bottom board.&nbsp; it should effect the absorbancy once it's finished.&nbsp;if sahould be as level as you can make it, (the legs anyway, as the table is gonna get a long of puching and shoving.<br /> <br /> once you pour the plaster, use a 2x4 to smooth the plaster before it sets...<br /> <br /> it dosnt nee dto be terribly level,just solid..&nbsp; though wose comes to worse, you can bolt it to the wall....
Moose G. -- can't tell you how delighted I am to see more pottery-related instructables.&nbsp; This one is a terrific idea.&nbsp; <br /> <br /> I have a couple of recommendations to make it an ace.&nbsp; First, more information on the proper kind of plaster and the specific&nbsp;mix ratios would be really valuable.&nbsp; And then, minor, but important, it has a lot of typos.&nbsp; Please forgive me if I'm showing too much of my English major background.&nbsp; The quality of the steps and content are high, but they will sparkle after a good proof-read.<br /> <br />
ok, ill get to it as soon as I can,<br /> <br /> time presses and christmas sales are upon us..<br /> <br /> please note that this was put together at 3am, on a request from another instructable reader...<br /> <br /> the plaster I used was Hydrostone, which is a plaster used for making ceramic molds and is sold by the 35 or 50 lb bag. mixing instuructions are on the bag, though the less water you use the stronger the plaster.<br /> I generally mix the plaster until I get a mix a little thinner than sour cream.<br /> <br /> I use slow set plaster, as plaster of paris this thick sets up in about 5 min.. Hydrostone takes about 10 hours..<br /> <br /> you can get hydrostone pre-mixed in buckets if you can find a local dealer..<br /> otherwise get the dry bags..<br /> <br /> <a href="http://plaster.com/HYDROSTONE.html" rel="nofollow">http://plaster.com/HYDROSTONE.html</a><br /> <br /> you can also delux this table, by adding a upright to hold a angle wire for cutting caly while you are wedging it out, i dont , only becasue I carry a wire in my apron pockets..<br /> <br /> my next project will be finishing up plans for the kids wheel, then I'll be&nbsp; building a sawdust Kiln, and then prob the pug mill or roller table...<br /> <br /> one thing at a time...
ok,ill add a couple of photos of the prototype this am,&nbsp; as soon I make some go juice
Do you have any photographs?<br /> <br /> L<br />
yes, im still working on this (its 3 am)<br /> <br />
Oh thanks. But, believe it or otherwise, I don't have a Facebook account.<br /> <br /> L<br />
and early prototype, built in the same manner, I still use this table after 3 years..<br /> <br /> <a href="http://www.facebook.com/moosestudiospottery#/photo.php?pid=312340&amp;id=1310781861" rel="nofollow">http://www.facebook.com/moosestudiospottery#/photo.php?pid=312340&amp;id=1310781861</a>
