Gluing on the Bridge & Slotting the Nut

Another step closer to strings going on..

Bridge is measured aligned and glued on! The nut is shaped and slotted (it's a black horn nut in case anyone is wondering)

Yes I did remove that stray bit of glue on the left :-)

Finished French Polish

So the finishing is finished ... A good amber shellac, lots of thin coats and lots of rubbing.. It has the overall darker tone I was looking for now to install the tuners as fit the bridge.

French Polish

So far my preferred finish is French Polish, partly because it is relatively easy & very safe to do unlike nitro lacquer.. Besides that it has little effect on the instrument tone is easily repaired and looks great.

I use a technique taught by Robert O'Brien, which uses a very thin or light cut of shellac (less than 1lb) and many many very light coats. It works well and is quick (as far as French Polish goes)
Before, pore-filled and sanded

Applying the seal coats


Back finished

Finished the Bridge

Well since I built these bridge jigs there is only one way to test them out and that is to finish the bridge for this guitar. I think It turned out good.

Before -- rough ebony blank

After - Bound, slotted and drilled

The other side -- Saddle is black horn,
the pins will be Bloodwood to match the binding.

Jigs and More Jigs

A big and sometimes frustrating part of luthery is building jigs. Here are three, a very simple one for marking the position of the bridge pin holes. one for routing the saddle slot into the bridge  and one for routing the binding channels..

The keen eyed among you will know that I already made a jig for this based on the KMG guitars design. Well this one is similar but I hope an improvement that will work a bit better for me..

Very Simple Jig
Bridge is just clamped in and the position of the holes can be marked with and awl  
Bridge is held in place while saddle slot is routed 

guitar side references on the guide

This is similar to some production jigs I've seen and a static version of Charles Fox's I believe

A big part of luthery is getting the process set up how YOU like it. There are many ways do do each step none of them wrong you just need to find the one that works best for you and finding the right method to route binding channels and do it in a shop with very limited space has been a challenge.
