What's the material that you are expanding?

For copper you can use hard rubber washers tightened between two strong washers on piece of screwed rod.

For steel you really need a taper roller expander which are commercially made.

just looked on eBay searching boiler tube expander and it brought one up. Have a go.

Bri.
