Hi Redtails 3
The Graduate is 6 inch centre height and constructed almost entirely of cast iron, whilst the Jubilee is 5 inch centre height but only the bed, tailstock and banjo are cast iron. The headstock is a square section (viewed from above) and fabricated from mild steel plate as is the motor platform and outboard turning rest, also the rear bed support leg. Both machines occupy roughly the same footprint space.
The standard Jubilee weighs-in at about 280 kg. Not sure about the Graduate but has to be heavier at say 330 kg (guess).
I would imagine that a short bed Graduate would weigh pretty much the same as a standard Jubilee. Hope this helps. Can you advise your reason for asking?
Kind Regards Tudor
