In Topic: Chalices

05 July 2015 - 09:32 AM

Hi all, Hmm seems the one day I was away, every one seems to be clambering!  Thanks for the vote of confidence. At any rate, I can give you a few tips about the chalice and patens.

 

  • Throw off of the hump, first stems, then bowls.
  • Throw the stems upright as if they would be used. Use ribs to put in grooves and decoration. I usually add a little bloated area in the upper third of the stem, as it makes it easier-more comfortable to grip.
  • When throwing the bowls leave a little extra at the base for a trim fit cup. More on this later.
  • Trim the stems first. Best is to throw a chuck column that they will fit into. Try to keep the top edge of chuck dry and place stems upside down in the chuck, and trim. I try not to trim through leaving a small hole in the bottom of the stem for air passage.
  • Trim the cups with one stem in mind. I trim them so that a particular stem fits into an are of the base. This is a cup cut into the base the diameter of the stem. only about 1/4-1/2" deep. Then score and magic water or slip. Place the stem into the cup and while wheel is turning level up and firm up the base join with a wooden or rubber rib.  I try to design the stem and cup join so that they don't look joined there, but higher on the cup.
  • Remove from wheel and set upside down covered for first day then turn upright and uncover.

There are a few pictures and videos on my blog at the posting

Chalices for Communion sets, my way

 

Best of luck, I have been doing it now for over 30 years, and only time, research, and trial and error have gotten them here. I have seen these done several different ways, so as my post says, these are mine-my way. :)

Hmmm. It may help people to know what part of the world you are in. Most kiln manufacturers do not ship continent to continent for rather obvious reasons.

I use a punch method to open up, not to center. :wacko:

How much clay are you speaking of? I center 25# in one lump using my rt arm on the side and wrist/fist over the top, lft in traditional position. I begin by slapping in place until close to center, then finish as mentioned.  For larger amounts I have coned first with base wide low cone, then slammed second piece on top. this for pieces that were 35# to 40#. Most larger pieces though I took the easy road and threw two or more forms on bats, then joined them together to make complete shape.

 

Worse problem with larger pieces as I was never more than 180# and am now 145, is body support. I find it easiest to either attache the stool to the wheel some way, or to hook my lft foot behind the front leg of the wheel while centering.

You may try looking through this strand that includes a video and a few pictures of finished sinks. All in all the advice Mug gives you is good. I really would not work on a separate pipe, but use standard fitting with the seals that they entail.
