Hi , I am John from Bangalore , India . I am 62 ! Have been an electric bass player for some time and am owner of a furniture manufacturing set up. Mechanised. I am pretty skilled at woodworking so ; I have wanted to make an electric upright bass for a while now and recently on a trip to Spain I managed to get a tailpiece (3/4) , a bridge (3/4) and a set of Tyrolean style brass machineheads , (Though from Thomann ; Chinese made I suspect ) and strings.... I have procured mahogany for the neck and a piece of ebony for the finger board . I am about to start the woodwork and desperately need some advice !!! If I am not interested in playing with a bow , does the fingerboard have to be radiussed? If it requires radiussing anyway, whats the correct radii etc. I see online a radius of 45" , does this change from nut end to bridge end? Whats a simple but effective way to achieve precision radiussing using a self made jig for a portable router ? Am attaching a preliminary drawing that I made from deductions online.... Any and all help will be highly appreciated . If you ever come to Bangalore , India ; free stay , food and entertainments on me at my lovely farmhouse...... ?
