Heron's Aeolipile
Divided he ad:
Well it looks like a master plan.... Or two have arrived... Salvation (well salvage) of the tool is on going and looking good :D
I've been in a two man conference with John Boggie and we.... He has a solution to my problem.... It will cut an internal dome/hemisphere! :dremel:

Circlip:
Ralph, yer ball turner can turn an external rad, why can't it turn an INTERNAL one?
Blank diameter, rough estimate, the ball you have already turned, and this is going to work for any circular form punches you make, if you consider the cross section, the developed blank is half the circumferance of the ball.
You MAY have to anneal the Copper a couple of times, and don't forget a reasonable radius on the top edge of the Die. Just had another thought,why are you making a female form anyway? Try a Ring die first, again,decent rad on top internal edge and use a lubricant.
Regards Ian.
And sorryto be a PITA but wern't it Hero ?

Hi Ian,
Problems with the ball turner are few in my eyes but in reallity the internal cutting capabilities are not quire what they could be... The tool can only cut as deep as the tip due to the leg it stands on getting in the way, also the piece being hollowed must fit over the turret else it is a no go.
Got you on the blank bit... I'll give it a go when I reach the stage. Thank you.
The choice to make a female form was mine, I went through all the ways with John and decided I liked this one! .... What can I say I like the challenge! Even if it is proving to be a little difficult, I sure am learning lots on the way through! :thumbup:
I'll refer you to the link I think I posted earlier .... I suppose it depends on who told you about him first ehh??

Hope that answers all? .... I Know I don't always take the easiest or even correct path, but I do enjoy myself all the way there :dremel: :)
Ralph.
