Ralph,
Piddle on time. :(
Your single point bearing system, I think, will cause you a few sleepless nights. :bang:
That method is OK if you use one at either end of the ball. Having one point bearing will mean you will have to have it perfectly balanced to prevent oscillations and so large amounts of friction. Especially as you will be using a very unstable medium ie boiling water, that just cannot be balanced due to the formation of differing sizes of bubbles.
I have done a C-o-C to show what I originally thought you were going to do.

I was all set to add some ideas and C-o-C. Went to upload to my web site and they had changed my pass word. Spent the last couple of hours getting everything working again. Now my head hurts. :bang:
Hopefully I'll get something tomorrow.

Hi Chaps
My other idead is the same as the one John just posted great minds think alike, the only thing I can add is if you could get a taper roller bearing small enough it would be just the ticket :thumbup:.
I'll still post the C-O-C any way, I need to learn how to post off scans, up to now I've been taking phots and posting these.

Sorry about the "Dad's Army Joke" I forgot that our colonial friends may not get that programme, when we're on obout the 20th re-run,

John,
That is still the general idea.... I just decided to try other stuff too :dremel: It's all a bit of fun funding these things out :)
Don't worry I'm not going to let the side down :thumbup:
No rush Bernd.... How did they (who are they? :borg: ) change your password? That sounds a bit more than annoying!
What's your name? .... well with friends like that!! :)

Mmmmm, are you sure about that Stew? .... I just think they have had longer to learn from more mistakes!! :lol: (I know wierd sense of humour!)
Can you get taper rollers that small? (13mm OD, 5mm ID) I suppose they make em? I'll have a look around,check the pricing!
Got loads of little ball bearings to use first though :thumbup:
Well got work soon so..... Till later :wave:

I know this post my be a little late to the party but here is a great book on using the H type press for making shapes and stampings of sheet metal.
http://madmodder.net/index.php?topic=106.0
Along with a type of forum for users of a jewelry type or style of press.OR more correctly it is set up as an old style board. http://www.bonnydoonengineering.com/ceilidh/ceilidh.html
They use the Masonite,hardboard, and Lexan plastic along with Derlin for the die's forms and the big time use of urethane rubber of assorted hardness's. It also covers making a type of hinged cut out die for cutting out limited run numbers of silver sheet jewelry parts that can be used for the softer non ferrous metals.
Boony Doon also makes a type of saw that is used to cut out the flap die punch. Most all the info can be adapted to general home shop type use.
I can also recommend the book that I linked to in the resources it covers most answers etc.
Here is also a great resource for info on the use of urethane products. Source for those across the pond but it is a US source but you maybe able to track down the type of products near you!.
