The aim is to have a pile of neck blanks ready to go, so as to speed up turn around time from start to finish of an instrument.
And by partially carving the necks we can release stresses that may be in the timber so that we don't get any warping or twisting surprises after the instrument is finished. We do the intial roughing out with a Black and Decker Power File - takes about 15 minutes. Then finish off with rasps and files.
All of our necks are one piece so there are no scarf joints or stacked heels. We did build some that were jointed but weren't comfortable with the look so went back to the more expensive (and wasteful) one piece( they are laminated actually so there can be up to 5 pieces glued together to make up the neck.
The first stage is to get one true side on the jointer and then run it through the thicknesser to ensure both sides are square. The run through the wide belt sander in case there is any snipe from the thicknesser.
Here's a blank being glued. The black stuff is Vulcanised Paper (Fish Paper)

This is what it looks like after coming out of the clamps. Mahogany with a Padauk centre strip. The Mahog is plantation stuff from Fiji.

On Friday Dave and I went to Australian Furniture Timbers and bought some more neck stock. The ones on the right are Fijian Mahogany and the others are Queensland Maple (Flindersia brayleyana). The Maple is slightly heavier on average than Mahogany - 575 Kg/cu metre as opposed to 500 Kg/cu metre for mahog.

Here's a closeup of the two.

Here's a pic of some of the blanks that are ready to have truss rod slots roted in them. After the others are glued there'll be around 20 neck blanks waiting for the next body to be built. There's a mixture of 25.4" and 24.9" scale lengths.

Some of the mahogany was unsuitable due to knots etc so these got processed into neck blocks. Here's what was left over, edge routed and ready to be finish sanded and ready for glueing to rims. The other pile is Engelmann Spruce being prepared for tail blocks. These are from a packing box from Graham Hein. I'm also going to laminate some of this Engelmann to try and make an ultra light neck block.

There was also some leftovers from the Mahog neck blanks so these'll get processed into kerfed linings.

So there wasn't too much wastage at all which is always a problem when processing from raw lumber.
Thanks for looking.
