As some of you know I am in the process of building a a pear shaped bass. I mailed the plan to Paul Warburton who approved of the design and signed off As many of you know this shape is seen in many of the finest orchestras in the world... or so I am told. I really liked the shape and idea of building a bass of this type. I am making it as an orchestra bass with some solo characteristics. The emphasis will be on a dark, full sound with some brightness. I don't know what size to call it but the string length is 42.5 inches and it will have a wide lower bout and a narrow upper. I tried to hang up the full sized plan and photograph it but it didn't turn out too clear. So take a look at the rib bending form to get an idea of its shape. I really don't know how it will turn out but I am just going to plug away and build the thing as best I can. I thought it might be interesting for some of you to follow along a bit as I construct the Pear Bass. And since there is a serious contingent of bass luthiers here, I though I would just ask them right here instead of privately as I have in the past. I haven't got too far but do have the wood chosen and aclimating to my shop for a month or so. I keep it 45% relative humidity in there. I sawed the rib stock from 4/4 Red Maple that is very nicely figured. I resawed the back from 8/4 RM with a little better figure than the back. The top has been bookmatched in half. It is Engelmann Spruce that I got from Fred Lyman about 13 years ago in a trade. He got the old crappy church bass, I got as much wood as I could carry in my stationwagon. BTW if anyone knows how Fred is doing I would love to know. I hope he is well. First question for the luthiers: Arnold, Jeff and Nick... I have the blocks made, connected to the "false back" which is ramped like the back will be, ready to accept the sides. The sides are thicknessed, bent and cut to profile ready to glue. I am planning on putting rib cross braces at the places on the "false back" mold where the upright supports are located (see photo). Is this sufficient to prevent crack spreads or should I space them closer with more? What dimensions should they be. Flat wide ( 3mm thick and about 25mm wide or thin narrow (5mm wide 12 mm thick)? I am using spruce.
