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
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.
