I had an interesting talk with Rick Penta this afternoon. Some changes are in the works for bass neck blanks. Not all the changes I wrote about before but some that will offer builders some options. Rick's wife handles all the computer work and she also does all the selling on ebay and that is where the changes will be presented for awhile. Eventually there will be a new site for bass/guitar parts.
If one wishes to order a blank, there soon should be a note to send an email (via ebay) prior to ordering, requesting a bass blank instead of a guitar blank on the 223 model. You will have to request a longer blank for bass. A one inch longer blank will cover a short scale easy enough. A 24.25" length should cover a 34" scale. The stock length is 21.75" for guitar offerings. This is the measurement for the fretboard surface. Each upgrade will of course call for a apropo increase in cost, but Rick promised to try to keep it at a minimum charge for each upgrade. We did not discuss upgrade charges, it would depend on what kind of upgrade one orders and finished necks are not being offered.
Rick told me is was okay to mention how he cuts his neck wood (s). He simply cuts wood that has graining that bends with the neck he is cutting in order to have more than just end wood grain holding the neck angle. It is a trick he learned from years of building furniture and said it was common with furniture builders to do this.
I ordered a new bass angled neck blank 1" longer than a 223 model on the heel end (see earlier link for the ebay site), laminated out of three pieces of Honduran Mahogany.
