I think I will stick with my router and circle jig thank you. Nobody to bother here with the noise but the mice. From yesterday, finished up lat and did not have time to post it.

I bought a couple of classical rosewood bridges online from China, I can't even buy the wood for what I paid. I use one as a pattern if I want to build a bridge, for throw away builds like this I just plop one of these on. While you can build one with just hand tools I think the tricky part is getting the saddle slot right. I use a Dremel to router the slot, I guess you can cut it with a razor saw and then use needle files and lot of patience to finish it off. If you had a chisel the right width I could see doing it, I could make one but I think that would be out in left field for the type of person I am directing this thread to. That aside, A maple board from a hobby shop for the fretboard. When making the neck I prefer having the grain of the wood as shown. It just keeps the grain more perpendicular to the surface of the neck.



Truing up the top surface, well I thought I was. Afterwards I flipped it over and did the real top side. Wrote top on it afterwards. I did not have any short 2" x 4"s around so I used a block that I had cut and sanded at 90 degrees. Two sheets of 100 grit underneath and another upper body workout.



The end was rough from the saw so I cleaned it up with my file. Check with a square that you do not have it off at an angle.



Here we have the neck fretboard and bridge in place to see how things line up. We want the the straight edge coming off the fretboard and landing just on top of the bridge. I shimmed up the front of the body and the neck blank till everything lines up. Then I check the angle of the end of the neck blank to the body. I think I forgot to mention I had the neck block flat with a little bit of a radius at the sides. When I sanded and cleaned up the body I made sure the area where the neck with mate to was flat. This makes life easier when we join the neck to the body. If the end of the neck blank is not at the same angle as the body take the file, or sandpaper and block, and get the same angle.



Transfer the dimensions for the neck on the blank. I put a bought nut for a classical on the neck and drew a line from the string holes in the bridge to the end slots on the nut. Then I drew some lines for the overhang I want on the fretboard.



I cut the angle for the top of the headstock and then filed it flat on the vice. I put the block in the vice so the top of the jaws match the lines I want to file to. Then it is just file away till the file is level with either jaw.



Rather than use the handsaw I tried a hacksaw, I marked a line to follow well outside the thickness I want and cut a slot on either end and then down with the saw blas running down the slots I originally cut.



Something did not seem right and I stopped and cut down and knocked off the chunk. Looks like when I did the outside slots I was not at a right angle and the saw blade followed it and bowed cutting a hollow in the wood. At this time I am thinking I hope there is enough thickness left for the headstock, I don't want to glue up another board if I did not have to.



I cut the rest with the hand saw. Here I am cheating and using my drill press to cut a big hole at the heel end. I am sure you will forgive me, just saves doing a lit of filing with the round side of the file. I blame my weakness on the screw up with the hacksaw.



Cutting slots in the wood and then just knocking them out with a tap of hammer. I never went to the line as you do not have complete control how it will fracture and it is better to play it safe, easier to take away than to put back.



While the file does a good job if you have a fair bit to go using the round side can be faster. When you get close flip it over and square things up.



All cleaned up and marked for the next step. The headstock has just a little divot left. I tend to allow for the odd mistake when I lay things out, it saved me today.
