Right you lot are in serious trouble
I thought of that Allen but unfortutanely van Andrews supplies a composite drawing of ribs with alll ribs contained on same drawing. Id have to make 10 copies to make it work.
Anyway I made up a set of accurate cardboard templates and have made up most of the ribs....they seem to fit on the base alot better. Today Ill fine tune fit and start gluing up.

Martin,
That's looking good - certainly more sturdy than my "dunny seat". I don't know how you are going to use the form to support the ribs while glueing, but one thing I learned is that when you are at a point on the sides where the curve is changing, the facets are angled and not at ninety degrees to the side to side supports (a bit like an angled peghead). The obvious place is at the back of the lute (tail end) where your three pieces go down in steps compared with the central front to back spline of your mould which is the rib shape. As they appear in your first picture the ribs will be held too high at the tail - I don't know if you carved/sanded their profile later. The same is true of the neck block support. Also remember to cover the form with something to stop the ribs being glued to it rather than to each other.

Hi Dave,
Thanks for the comments and suggestions. The mold isnt finished yet...theres quite an involved process of shaping the top of the ribs using a steel ruler and cardboard strip.....ending up with a smooth profile for each rib. Before gluing up ribs the top surface of the ribs are waxed. I note your use of brown binding tape on your mold.
Cheers Martin

Looking at that mold reminds me of the mold I had to build for a cedar strip canoe I made years ago now.
The strips of cedar were machined with a cove and bead set of matched router bits. This allowed them to roll around the form and still have a tight joint with all the those compound bends. Those strips were 1/4" thick though. It would be interesting to figure out if a similar thing could be done with such a small scale?

Okay not a good day today....started out ok with a leisurely breakfast at loacl cafe but at 11.45 it was root canal time. I managed to make a bad situation worse by asking my female dentist when her baby was due.....she wasnt preganant (makes mental note never to ask a dentist about to start a root canal if shes preganant).
Anyway got home and got back to work on the "Armadillo". van Andrews instructs to use a chisel to shape the ribs but I found it both quicker and easier using a block plane, dragon rasp and a sanding stick.

Niiiice, looking forward to following this build Martin. There's something special about lutes, I guess it's the skills needed to make one and you know they were all hand made so it's easy to appreciate the craftsmanship.
Doesn't look like an Armadillo at all tho, looks more like a giant weta's shell to me

Take the Mahogany spacer out and cut the centre of your base out and there's your huge codpiece.A dual purpose moldkiwigeo wrote:Mmmmmm might as well start looking for a costume to go with this lute. Wonder where I might find some Elizabethan breeches and a huge cod piece??

I did the same at the start of my haircut. She did a great job, bless her.

Looks great Martin. Ever build boats?

Worked on the neck block yesterday. There are a few choices as far as wood goes, I went for Honduras Mahogany as Ive got a bit of it lying around the shop and its a favourite wood. The block gets secured to the head end of the armadillo and gets carved to shape with chisels and rasps. The important thing is to acurately carry on the facets from the ribs through to the neckblock. It looks easy but it ain't.
Working with the 25mm Stubai.....my favourite bench chisel.

Working with the dragon rasp...one of the most used tools in my workshop.

The end result.

I was thinking "wooden bike helmet".....Kim wrote:Nice work Martin, you must be enjoying ur'self because the mold looks very good.......still reckon it looks like a Trojan sheep though.
Looks like a great project going there, can't wait to see the final outcome.
And we get to watch!
