Learning curve with the new gun, but it is going well. 1 lb. cut is way too thin, whole room fogged right up. I spayed with the 2 2/3 lb. cut and throttled down the gun and it is going on nice. A lot has gone down, so I guess I will do some level sanding next.

Run Out is appearing, but only in one part below the bridge. This seems odd.

Clearly, there is a continuum. At one end of the spectrum, you have someone who cuts their own tree, processes it, dries it, and makes an instrument from it using basic machinery and hand tools, performing each and every step in the finished instrument. At the opposite end of the spectrum, you have someone who buys fully completed components that require only glue, assembly and finish application. What about someone in the middle who does most of the work but outsources something like fingerboard slotting? What about someone who does everything else but outsources finish application? What about a guitar that is made by an entire assembly line, where each person on the assembly line does one and only one step towards the finished instrument. Even if each and every step is done "by hand", is that a "custom-made" or "handmade" instrument? Does it matter if both the assembly line instrument and the one-guy (or gal) made instrument are "quality" products? Then there is the issue, as you raised, about automated machinery and processes (e.g. CNC). Manufacturing in the 21st century: lots of questions. Not many answers but probably lots of opinions that are, effectively, answers. |

Very valid points charles,
I make or teach right down to making kerfing, but I do not give it a second thought when someone uses pre bought kerfing in their builds as it makes no sense to make it (labour / time wise), so I need to rethink my interpretation I guess of what constitutes a custom built instrument. Steve

Spraying rather than French polishing...
I’d be interested to know why you’ve chosen to spray on shellac rather than to French polish the instrument.
One of the big advantages of French polishing with shellac is that you need no specialist equipment including room ventilation. The downsides include the finish being delicate and French polishing technique being both time-consuming and tricky to master. |

Level Sanding, Phase I
I have this down to a science lately. I used to approach this step in a haphazard manner and the results were inconsistent. The first coats I put down where not necessarily that precise, my goal is to get down quantity and not quality at this point. The first block I use it a rigid foam block with 220 grit 3M Stikit Gold. The low spots become obvious. I will then airbrush the low shiny spots and then give another series of coats. The neck doesn't get sanded at this point because its surfaces have been consistently contoured sufficiently.

Airbrush Touchup Setup
This Paasche HS-202S single action airbrush is perfect for getting down some shellac quickly in specific places.

Getting There
Going on smoother now
PS: I figured out why some photos are not straight even though they appear straight in my phone. It happens when I am facing phone down to take picture.

36 32 Watt Fluorescent Tubes
I couldn't resist adding 1 more to make it more symmetrical. I bet I wont have trouble seeing any drips now.

I built a 16x12 motorcycle workshop with a 12-in-12 roof. The ceiling is
"cathedral" I aim to put light panels on the sloped parts like you did. I'm intending to use some LED panels, are your tubes regular florescent? -Mike "need light to work..." |

Yes, but I will be switching over to LED tubes at some point. These fluorescent tubes don't last long, I am constantly replacing them. I have 108 4' tubes in service right now. Basically 1 a week will fail. The new LED fixtures are pretty efficient and compact. I just wonder if I had that many LED fixtures how many would be failing without an easy way to fix or replace them in the future.

Lighting aside, your last pictures of the guitar show inadequate atomization and poor flowout. You'll end up sanding almost all of your finish off to get it level.
To spray finish, you need a compressor that pushes enough CFM to drive a full size gun, or at least a touch up gun. Your woodwork on the guitar looks real nice though. |
