Thick Semi-hollow Project


Geo

Recommended Posts

This will be my third "real" guitar build. Flamed maple top, chambered mahogany body, maple neck, bloodwood fingerboard and headplate, LP Jr-style bridge/tailpiece. Being a cheapskate, I'm making my own pickups.

My top is 3/4" thick and my body 1 3/4" thick, which adds up to (you guessed it) 2 1/2"! I will do some radical carving of the top and back to slim it down. It feels huge right now. I didn't route the chambering very deep in the body (about 1"), meaning I have lots of room to carve a comfortable Strat-style gut recess. You'll notice on the body that I have left about 3/8" around the outside bottom un-routed. I will be rounding/carving the edges pretty heavily, and my bearing bit couldn't reach much farther.

For the pickups, I'll be winding two P-90's. I made wooden bobbins, which I know is not the best plan. However, I plan to wind them rather loosely in the hopes that there will be room for the bobbin to expand without busting the wire. For the pickup covers, I'll cut up a rosewood acoustic bridge blank from a failed "project".

The guitar will be totally natural in color, with an oil finish. I'm thinking the woods should look pretty dramatic.

Any comments appreciated. :D

That's a very pleasing shape, very well thought out composition. Also like the constellation idea.

Looks awesome! :D I like the shape, the woods, and the inlay idea. Since constellations consist of dots, you'd think that there would be more inlays like this, but this is the first time I've seen this idea. It is also cool that they are still on the usual frets.

Thanks guys! :D

I'm envisioning more complex constellation inlays in the future. You could get several different sizes of rod to represent different magnitudes of star. Only astronomy geeks like me would recognize the patterns, but it could be pretty sweet.

My next challenge is to route the neck pickup cavity. The end of the fingerboard will provide part of the template, so the jig that I make will have to be recessed from beneath. (I need template above the fingerboard for the first passes.) Probably doing it the wrong way, but oh well... :D

That inlay is simply fantastic. What a great idea! Coming from an astronomy freak, I really like it. Do more inlays like it! You've really caught my eye with this one, keep up the good work.

Thanks dude! I think Perseus could make a cool inlay. It's sort of a "long" constellation with a lot of clusters and stuff. Of course, no one would recognize that one....

Yeah, that'd be nice, it wouldn't be too "crowded." I might do something like that for my next build, I know a guy who's amazing at inlaying :D

I was looking at your fullsize plans, though, and I wanted to know if those tuner positions were the final positions? The break angle over the high and low E strings looks problematic...

Yeah, you're exactly right. I adjusted the positions on the plan after I took that picture. In the original plan, I got a little carried away with making a headstock shape that complimented the body shape. :D

I routed the neck pickup pocket and drilled the bridge post holes. After final sanding, I can start finishing!

Well, the guitar is MOSTLY done. The neck pickup is reading open, so I have to take it apart and fix it, and I haven't installed the truss rod cover; but otherwise it's finished!

The tone is amazing. I need to do a little more fret leveling as it's a little buzzy in some places, but otherwise it rocks.

Some videos of me playing it...

This guitar was built without a drillpress! :D

What neck angle did you end up using/ whats the scale length?

I never was able to measure the neck angle on my plans or on the actual guitar because I can't find my protractors. :D (I have two or three!) It's a fairly steep angle for the bridge, though, and it couldn't be much steeper (although the bridge is plenty stable). The scale length is 25 1/4".

If you're wondering about a neck angle for your project (I'm reading into it here)... it's best to get your bridge and then base your neck angle on that.

@willy: glad you liked it. :D
