I need to have a Bridge Rectifier 250V 40a ..... unfortunately
there is no such thing available as far as Google can see

Can anyone tell me what size Diodes that would work ? I am just a
hobbyiost and anything for instructions that I have found, look
like they need a College COurse to navigate.

Any suggestions or simple equation ?

A bridge only works 1/2 cycle so you would need at least 20 amp
diodes.

Huh? Where do you get that?

Despite only operating half-cycle, each diode gets the full current
flowing through it, so you need *at least* 40A diodes, better yet 40A.
