What a pleasure it is to participate in a list with such people. We have 
three approaches to the forming of a lute body. We have three experts 
advocating their own approach (two of them the primary sources, David and 
Dan - and the third a student of the late Bob L.), and we have no argument. 
Some of you may have spent time on the "lute list" and seen the arguments 
over the number of angels who can sit on the head of a pin (is it a baroque 
pin or a renaissance pin).


Dan's photos of his jig are good, and I think I see how it works. David's CD 
is my bible (when I get back to making my lute - my lady and I are in 
negotiation to sell her NYC Co-op and my NJ Condo and move to a joint 
apartment), and I think I'd be more comfortable with Bob's solid form as 
described in his book.


A side comment on the above, the conjoining of residence will reduce our 
separate expenses greatly, and increase our space. Over thirty years 
together and we finally get a bit of sense! (but I've only been here in NJ 
for 12, used to be a couple of blocks away in NYC). I will get a 15' x 15' 
bedroom for a small bed and a large workshop (instead of having my lathe and 
workbench in a walk-in closet - and the rest of the tools in the bedroom and 
living room). She will get a living room to decorate, without my sawdust, 
and a bedroom next to it. I will get an attic to keep my spare wood and 
seldom used tools (as well as her twenty boxes of summer and winter and 
spring and fall - and should she go to Mars or Venus - traveling clothes). 
At that time I'll get back to my lute, and the "clearsach" carved harp I've 
planned, and the easy manufacture of my own designs for psalteries. I hope 
the deal will be consumated shortly, but there is a potential block on the 
funding due to her Co-op Board - something annoying I shan't explain here.


Back on topic. I agree with all three approaches. I like Dan's approach of 
the variable jig - but then when I see the "ego wall" that David offers in 
his link I am awed (and David, the term "ego" in that isn't meant as 
insult - the "ego wall" is a standard US phrase for the wall of diplomas 
that doctors and lawyers (and some less qualified) display. You have joined 
another friend (that one a lad of 70 that I sang with some 55 years ago, and 
ever since each year) - his "ego wall" is the shapes of the boats he has 
designed - Rod's J-boats are perhaps the fastest class boats in the world in 
all classes, or perhaps only in most - and he does custom work as well - and 
all that as a Princeton Tigertone with a bit of a love of sailing, and a 
talent for design discovered in middle age. The Wind in the Willows, water 
rat like nothing better than messing around with boats, just messing around 
with boats.


I can't speak for Bob, regretfully we lost him too soon. But David has 
already done so with the magnificent wall of solids and skeletals. And Dan's 
pictorial of his cutting jigs shows us the shape (pun intended) of his 
process (although I'm not yet clear as to the gluing of the ribs, is the 
"last cut" rib on the form - or is the jig arc put aside and the ribs 
contained by the frame). Whatever, there is a real dichotomy here between 
the beginner and the professional - and that is not meant to imply any 
choice between them. It is David's wall of forms that tells me what I should 
do. At my advanced age (72) I may make but one lute from a form, I want to 
make that one carefully. I confess that I'm a bit less concerned now having 
found a local vendor of good woods, my cherry ribs that I carefully shaved 
down from 1/8th after buying them from Exotic Wood a two hour drive away 
aren't as sacred ( or as expensive) now that I have my own facitity for 
resawing. I may blow those ribs in a practice test, and then make my own 
from scratch. LMI and Exotic Wood are the only two instrument quality makers 
I knew when I started. Now, or at least when I get the new shop set up, the 
only thing I'll need to buy is from a musical wood vendor is the soundboard 
(no way I can do the resawing that deep, I'm limited to five inches). I'll 
go for the Englemann, or German, guitar soundboards and shape them - unless 
anyone has a better suggestion.


Should I live long enough to make lutes for sale (and that would require a 
number of years, not for my skills but as lutenists are picky about the 
reputation of the instrument), I'll try all three methods. But for now I 
think I'm going to be happiest with the solid form (although I might note to 
David that my skeletal, as per your instructions, looks pretty good - I 
might try forming on that first - in fact I should since I now can make new 
rib blanks - I guess I'm just in love with my draw knife and spokeshaves - 
and trying to put off the "day of reckoning" in shaping the ribs).


A note on my work on psalteries and harps. I'm comfortable with the good 
laminates of Swedish Aircraft grade birch, or a five ply 1/8th of Sitka 
Spruce - the soundboa

Hi all,

I might add to Dan's explanation that a single jig can be used for lute bowls 
with differing numbers of ribs.  My one jig is set up to produce bowls with 9 
ribs or with 13 ribs.  The pivot point stays the same; you just have two sets 
of indexing points.  So far I've only used it to make a bowl with 9 ribs, but 
this winter I'll be making myself a lute with 13 ribs.  

Honest guys, this is the best thing since sliced bread.  It really works.

Dear Dan and All,

 I put some pictures of one of my cutting forms up on my web site 
for you to see.  The URL is: 
http://www.daniellarson.com/cutting_jig/cutting_jig.htm

 The more complex bowl forms are achieved, in my system, by 
changing the indexing and pivot points.  By doing so just about about any 
shape of rib can be realized.  The form pictures is set to cut three 
different shapes of ribs for a flattened back.  This system is even capable 
of reproducing the Vinaccia mandolin form, which, with it's raised 
flattened back, is about as complicated as a lute form gets.

Regards,

Dan
