Alright Luthiers, Lurkers, and Subscribers...
Another fun-filled, productive day!
Where do I start....Radiusing!! Since I had my neck and tail blocks glued in, and there was no line, it was time to tackle this piece of machinery...
Yes... a modified potter's wheel. There are two allen head machine screws in the top of the wheel, which match up with two holes in the hollow sanding forms..50' radius for the top, 15' radius for the back. Before sanding, you must split the mold in two, to give you access to both sides.
The only trick about this, was to keep everything level and hold your two blocks as you spin the wheel and sand. I will include some mostly after pics.
Next, was work on pickup routing.. I double and triple checked all my spacing, centering the template, then began to hog out with a forstner bit. You guys have seen that before, with the tele ( a couple of pages back). So, without further ado...
Music Man Goodness!!!
I also worked, without frustration, with a 6" cabinet scraper. I started to smooth out my mistake on the comfort carve.
You may or may not see my boo-boo, but I stopped for two reasons, 1) I am out of shape, and this scraper is not sharp. also 2) I created quite a lot of heat, and the scraper was gettin' HOT!!!
I also worked on smoothing out the burn marks from the router w/ 3/8" roundover. I will continue to work with 150 grit, then 220. getting it baby smooth. I stopped the path of the roundover before the elbow cut. I am waiting for assistance with that. I DEFINITELY DON'T WANT TO SCREW THAT UP!!!!
That sums up the majority of the work on the bass. We have to start designing our control cavity layout, and I got approval of mine, but, John Reuter was not aware of my 3/8" roundover, so I am reworking it tomorrow. I will be using SD Music Man w/ Alnico Magnets; SD 3- band, with individual bass, mid, and treble. The way I see it, I would rather replace one pot, versus a stack pot, if one goes bad. I will also be using 18v. Why, you say...because I want to! Hehe..
Moving back to the acoustic, the soundboard was thickness sanded today, and the rosette looks awesome!!!!
There are no broken lines, all the seams are great! I will remember to take a close-up tomorrow...sorry about that.
The final big thing today was kerfing. Matt Baker asked if he could demo on mine, and the way he asked was "McCray...do you have your blocks glued in?...your neck block...your tail block....are the sides radiused?" I think he was expecting me to say no at some point...Man, that was a good feeling. Anyway, we are using reverse kerfing, which is glued in on the perforated side, versus traditional kerfing, which is glued in on the solid side. And here you will see these fancy luthier's clamps...calibrated to 20.25 lbs of pressure, just for luthier's work....
Yep...I have to wonder how much office workers pay for these highly specialized luthier's tools...
I was able to get all four strips of kerfing glued and dried before time was up today. Here are some in-progress and completed pictures..
That's all for today. Hopefully tomorrow, I will get the fretboard face inlay dots for the bass, get some more contouring done on the bass, and I think we will do vertical strips on the acoustic sides, then radius them for the last time. Then, the back and sides will be almost ready. I know we will still route out for a wedge in the tail block, but, I am getting ahead of the game. Tune in tomorrow, faithful watchers!
Oh, and CT, I apologize, I failed to address the point the the neck pocket. I sir, am also looking forward to shaving off that growth on the treble side of the neck pocket. I have a good idea, but, I think that will happen after we carve the neck and mount it with machine inserts...that's right, no neck plate...very modern! But, with that being said, I want as little left as possible!
Sincerely,
