I wanted some 5 mm hardwood for my fret boards but none available off the shelf. The timber I chose was Kwila / Merbau. Hardness rating HARD (The Australian Timber Database) Available DAR at Bunnings (140 mm X  22mm ). I found a business at North Arm just outside Eumundi Queensland who would size it for me (2 x 2.4 metre $15. ) His main business is preparing slabs of mainly native hardwoods for bush furniture, breadboards etc. He sized for me to 5mm a piece of Camphor Laurel (a weed) about 2 foot square to make a sound board. I think he could size below 5 mm. I am getting timber there in the rough but with the natural grain of the timber to follow the line of the neck and a offset head.

HD,

The scale is from the point where the free vibrating string contacts the nut and the bridge... On a bolt, that is approximately the center of the diameter of the bolt....

 

This is only significant on larger bolts.  (I have seen bolts as big is 1/2" used, but I wouldn't advise it.)

 

the best,

Im using a bolt as a nut. wondering if I position my fret scale from half way accross the bolt or to the edge of the neck as I usually do?

then polish

I tend to use Polycrylic by minwax.   Its a water based urethane that does not change the color. Fast drying and about 3 coats and rub out with 0000 steel wool you get a great finish.   I use oil based urethane when I want that amber color change. Much longer drying times.  For oil finish try mixing the last coat with some butchers wax, the polish.

Using a penetrating oil may darken the tone as it sinks into the pores of the wood--which is fine if that's what you want. Most pro instrument makers will finish with shellac, varnish or another film type finish, which sits on the top of the wood, leaving it with essentially the same song.

1.  Nearly finished my first CBG. What do you coat it with. I was going to use 2 pack polyurethane for the neck and fretboard and either beeswax or furniture oil for the sound box ( no paper covering0 Use a mixture of Australian and timber from Indonesia cor neck and fretboard. By the way many thanks for the help on fret placement.
