In Topic: When You Throw, What Do You Aim At?

Today, 09:55 AM

When I throw pieces it is usually 20 at a time at least. I start with the first one , slowly carefully working the form to what I have in mind. Then the next one a little quicker, still looking at the form. The last of the 20 is done in half the steps, form fully to my vision, and done so much quicker than anything before. Many times if the pieces do not get handles, I will do a second set of twenty as these will happen so much faster.


In Topic: Pugmill As Extruder - Will It Work?

soft would be OK, not wet though. Getting used to your pug mill for doing this will be trial and error, but it will be worth it if you want to use extruded forms for handles, tiles or other forms of construction. Would work well if you are looking for coil construction coils even though these coils would be very consistent with little character.


In Topic: New (Old) Wheels And (Re)Learning To Throw.

Threw on a kick wheel by Amaco for a few years. Yes get used to throwing slower, but boy are they great for trimming. I like the slower speed for control and chattering. I got to where I could get it moving faster allowing more time for pulls, but you have to time the start of the pull to your max speed, and let the wheel slow as you pull up-which is the natural way with pulling. At the same time be careful of trying to run the treadle when pulling as you may get a vibration up through the shaft. 'Good timing is really best.  At the same time, you may find that the two of you switch back and forth on wheels. Powered on for larger pieces, treadle for smaller bowls, mugs, vases, pitchers etc and definitely for trimming.

Those are made for individual smaller solid extrusions. The one on the bottom left looks like it was designed for handle shapes, the top one for mostly bars, and the bottom rt for slab/tile shapes. None of these are designed for a hollow form.I would think you should extrude about 18 to 20 inches and cut it off carefully on to a board and separate the individual pieces immediately.


In Topic: Difference In Digital And Manual Kilns

Hey folks, part of your answer is already answered. If you check the Orton cone chart you will find that at a rate of climb of 108F./hr is 2232 for a ^6 cone. Check that against a small ^5 and that is 2230. So you could fire a kiln at moderate climb and get cone 6 equal to cone 5. At the same time, they call for a ramped firing(10 min hold).
