I get the impression it is quite big !

Give details of size, weight, VA, Vac, windings, turns or turns ratios, etc.

wow...nice build sir....it's really nice building your own trafo especially if u have those equipments....customizing trafo for you own use is really a factor and sometimes cost saving rather than buying ready made trafo that not exactly as u want...some store sell trafo of false VA rating just voltage and amperage and you dont know wether it for a single wind rating or dual...if you not familiar with the core size you can be fooled.
