Suitable Hydraulic Mechanism for miniature table top shear machine

Suitable Hydraulic Mechanism for miniature table top shear machine

(OP)
Hi,
I have a table top model of Din Rail Cutter which is just a miniature hand operated shearing machine operating with a 1 mtr. long lever. It cuts m.s.channels of 1.6 mm thick in U and J shape easily. There is one fix and one moving die plate with slots to allow the U and J channel to be inserted.The total cross section of the m.s.channels is approximately 240 sq.mm.
Now I want to incorporate the feature of punching 10 mm dia holes in 10 mm thick copper flat bar by modifying the die plate to have a hole punch at the bottom.How much force will be required and what should be the length of the lever ?

Alternatively can somebody suggest suitable hydraulic mechanism for this operation ?
Thanks in advance.
Regards.
