Channels...

Using some tape as a depth stop I made a start on removing wood for the carbon fibre reinforcement rod channels.

Half way through the first.  It's easier and neater to drill lots of sequential holes and then join the dots with a chisel than to try and carve the whole channel with just a chisel.

Thats the first done...

...and the second.  Unfortunately the tape moved and I drilled a little deeper in a few places than I'd intended so I've added a little meranti and glue filler, hopefully this won.t come through the other side when I carve the neck profile.

And some chiselling...

Thats one, and on to the next.

And now two rod channels

Now for the centre truss rod channel, oh my maple is much harder to drill than meranti...

A couple of hours later and we have a truss rod channel.

Drilling with a brace and bit into a sloping surface for the truss rod adjustment hole was erm... interesting...

Not too bad even if I say so myself!

That's the carbon fibre rods glued in with epoxy resin and trimmed to size.

Here it is with the truss rod...

Oops, made the truss rod channel a little longer than required...

... and easily fixed with a small cube of maple.  The truss rod is held in place with a few globs of silicone sealant which will stop it rattling in the channel but wont stop it from working.
