Just starting a Flamenco Negra

Hey John,
Is carving the neck before attaching an option?
Herman

btw beautiful binding.

Yes and some do carve the neck before. I rough carved it but there is no reason it can not be completely finished.

Moving on I decided to have square ramps and for nun to square the the bottom of the slot to match
I used a scalpel to score the lines for the slots using a ruler lined up with the slot edges as a guide. With the slots scored, I used a razor saw following the score can cutting to depth on both sides of the ramp. I stayed inside 1 mm or so.







With the sides of the ramp cut I cleared the waste with a chisel



I used a paring chisel to clean up right to the scored line. The edge of the slot made a good guide for the chisel.



Then just for fun I squared the bottom of the slot as well.

I mostly used a chisel but I also cut a sanding block the thickness of the slot.





One done



It will look OK.



I used my mini mill to rough out a bridge. I started with a blank thicknessed to 7 mm and sanded and planed to size. On that blank I laid out the rough cuts in pencil. I use the milling machine to actually position the bit to a measurement. The lines help as I can check if I made a mistake with the numbers of rotations.





I cut the saddle slot and the tie block, then follow up and cut a ledge for the bone edges.



I used CA to install the bone strips and then cut the side edges of the tie block and saddle block. and proceeded to rough clear the wings. A bunch of slow 1/16" paths. Doing it this way allows me to make a clean perfectly square cuts for the two blocks.





I used a chisel to bevel the inside ramp to the saddle.





I used a fine rasp and chisels to shape the wings





Then I use a blade sharpening guide to bevel the wing ends.





A bit of quality time with chisels, scrapers and sand paper and I have a bridge.







I used a drilling template to mark out the holes for the bridge. I chickened out and only did six holes. Sorry no picture drilling the holes. I have a block with a 3° angle that I clamp to the table of my drill press. I position the depth for the holes and clamp the table anyplace. THat way I can just slide to the next hole location.





I positioned and centered the bridge. I will have some nut compensation so I only have a bit more than 1 mm of saddle compensation. I used a centering guide that I index on the nut (in this case a spacer). I have a mark where to put the saddle. (I double check after taping in place.)



To make sure the center is correct, I stretch a string on the string paths.



I drilled a a couple of index holes in the saddle slot and cut a mask for finishing





Enough for today!

To Finish the guitar I am doing a French Polish on top of Silvertip Epoxy for the neck, back and sides and bare wood on the top. I want a perfectly level instrument coming out of the pore fill so I spend a lot of time. I have learned if I can not level the pore fill without sand throughs, I will never be able to level a finish. On this instrument I did an ok job on the back, but during the pore fill I found some low spots on the sides. So I kept applying and sanding level until the pores were filled and I could sand it level without sanding through. I think I applied the epoxy 4 times. On the last application I sanded back through level to where I was getting sand through. At this point I knew I had a thin coat of epoxy at most. I mixed a new batch of epoxy diluted it 50% with alcohol and wiped it on very thin with a cotton rag. I started my French polish the next day.

Ready to apply Silvertip epoxy.


First application



I am leveling the fill with 600p.



The coats are left very thin. I try to remove all of the epoxy with a plastic card.



Starting to look like a guitar





I still French Polish using a technique I learned from Robbie O'Brien French polish class. It is the best most repeatable method I have used. If one has the patience a guitar can be polished in a day that looks good off of the pad. This was after 1 hour of work. It is about where I would stop for a top, but I will continue working for the back and sides. I can not say enough about Robbie O'Brien French polishing technique and his on line class. I have successfully learned a few different methods including Milburn's. Robbie's is the clearest most straight forward, and repeatable method I have tried. For me it was worth the cost of the course, I have use this technique on most of my classical guitars.

I just completed my Flamenco Negra.

There was not much to do I glued on the bridge and fretted the guitar.

With the fretting I removed the barb of the fret for the last fret out over the sound hole and just glued it in with CA






I got to use my new LMI vacuum clamp



Made a nut








A new flamenco!
