Ok sorry for the lack of info. I asked this question last night after a long day. I should have let you know that I am a professional luthier. I have been so for 29 years. I have made violins, violas, and guitars in addition to fretted and bowed instrument restoration. The extent of double bass repair that I have done has been mostly school basses and lost of Kay basses for the area blue grass people. I purchased this bass and an old flat back from friend a month ago. The top was off and there were no fittings aside from the tuners. The bass in question is fairly healthy overall.
1. The bass bar was a monolithic type.
2. The conversion date is not known
3. All the maple has air brushed enhanced figure
4. The bass bar will of course have to be replaced
5. The top grads are 9mm at the post area to 5.5mm at most of the flanks.
6. The back is roughly the same 9mm along the center joint to 5.5-6mm at flanks.
7. The neck width measures 42mm at the nut to 68mm at the end.
8. The neck is a dove tail type joint.
9. A low “B” is what has been suggested.
I am doing this to perform repairs that I do not feel comfortable doning for customers but mainly for the love of the trade. I will try to post some pics but this is new to me so bear with me.
Questions
1. Should I leave the top and back thickness as is?
2. Should I go thru a scroll graft to increase width and change to mortis type neck joint?
I should also say that I have done cello scroll grafts so I am not afraid to do this.
