You know, I really really like the Dimarzio Evolution for a rock/metal bridge pickup. I tell you what I'll do for you, Eli. Let me know when you're ready for the pickup. I happen to have one kicking around in a crappy, old parts guitar that I didn't even build. I'll send it to you. You can try it. If you like it, you can keep it. Consider it motivation to get that thing strung up and playing.

I start with 80 grit. That will make quick work of saw marks, tooling marks and other scratches. The key it to remember to progress through the grits and don't move on until all of the scratches left by the last grit are gone or it will take FOREVER.

I also recommend leaving everything ROUGH until you get to a step that you need a smooth surface to go off of. You will undoubtedly get little nicks, scratches and chips during the building process. It's best to leave everything rough, do all your damage, and then finish it off one time instead of having to go back later and fix all this stuff in the final surface.

So the progression would be:

1) sand with 80 grit until all the tooling marks are gone. Use wood blocks/dowels and whatever else as a sanding block...don't hand sand anywhere unless you absolutely have to...you will regret it later when you try to level the finish. When you're done with the 80 grit, you should have a nice 80 grit scratch pattern over the entire guitar, and every tooling mark/deep scratch should be gone. At this point, treat the guitar like an egg. Don't put it down on anything except a towel (or I use anti-skid foam that I keep clean and free of any debris). Putting the guitar on tiny stray bit of wood chip or whatever can leave a dent or scratch and have you starting all over again. At this point, you're no longer woodworking...you're finishing and unless you want it to take forever, be very very careful and work clean.

For hand sanding, I go
2) 120 grit to get rid of the 80 grit marks
3) 180 to get rid of the 120 marks
4) 220 to get rid of the 180 marks
5) 320 to get rid of the 220 marks

For powered sanding, I find it works just as well to do 120 straight to 220.

And at that point, it's usually ready for finish. You can actually stop at 220 for purposes of laying down a finish, but I find that the slightly smoother surface of the 320 helps the initial coats a go on a bit smoother, making it easier for my to judge whatever color I'm applying, especially bursts.

Keep the paper clean and unclogged. Bits of stuff stuck in the sandpaper will leave deep scratches. Sanding goes very quickly if you take your time right in the beginning, pay attention to the details, don't damage it as you go along, and don't move on from that 80 grit until you're really truly satisfied that the surface is right. I swear, half the time I spent finishing on my first few guitars was fixing damage I introduced during the finishing process.


Wow, thank you! That answers my question completely!

Look on ebay for some used seymour duncans. I have always liked the jeff beck for a bridge and the SH59 for the neck.



Good call! A JB in the bridge and an SH59 in the neck is the most popular pickup combo ever. Sold a ton of them back in the 80's when I had my shop. Very versatile.

It's nice to see how much this thread has turned around. You've got people sending you free pickups now. Congratulations. Hope it's going well.

If you haven't set up a new blade in your bandsaw yet, here's a video on set up:



Although one thing to keep in mind which they fail to mention is to make sure your bandsaw is not only off but UNPLUGGED while changing blades. Safety first.

Thanks for the pickup offers guys, and the bandsaw video. I'm pretty close to choosing my pickups. I'll let y'all know when I'm at that stage.

I think I'm going to go buy some grittier sandpaper than 80 because it is just taking so long to get down to the line with 80 because I made my cut quite a ways from the line in places. The 80 is making it smooth also.

You might take a look here http://cerditoguitars.wordpress.com/. While it does illustrate what a lot of the people here have been saying i.e. you won't necessarily get what you want on the first one... Which by the way, most experienced builders and the authors of the best (on the subject) books say often, there may be one or two things in there that possibly can help. And I do believe it's possible to create a superior first guitar, I just couldn't do it on the first try. But by building it yourself there's no end to the possibility of revisions on the project. If you read through it, you'll see I'm currently on revision #1 :D And that might turn out to be even more fun than the original. So keep at it, and work slowly and carefully, and you should be able to come up with a guitar you love more than any other... because you built it.

Thanks,

Actually, the build is going wonderful so far. I actually think this will be one hell of a guitar when I'm finished.

Hey guys,

So I'm getting ready to build the neck and I have a few concerns I want to clear up before I get started. First of all, are there alternatives to a fret saw that I can use to cut out the frets? I still have not calculated and measured the frets. My book talks about using the 12th root of two method. Does anyone else have a better way? Any valuable advice for neck and fretboard building?

There is a much easier method to calculate your frets. It's called the Stewmac Fret Calculator, free online:
http://www.stewmac.com/FretCalculator/?gclid=CLaM8Je4krECFeUBQAodfDOKeA
Just type in your scale length and how many frets you have, print it out or write it on paper.

Fret saw works fine for me, but there's also the fret scale templates
http://www.stewmac.com/shop/Tools/Special_tools_for_Fretting/Dual_Fret_Scale_Templates.html?actn=100101&xst=3&xsr=3423
You won't have to calculate your frets for this method but you will need a table saw and a blade with the proper sized kerf.

Advice: Route your truss rod channel before you do anything else. Easiest to do this while the neck is still a flat rectangle (squared on at least 2 sides and before you taper it) so you can just guide it along a fence on your router table down the centerline of the neck blank. This is if you're doing a two way truss rod with a glued on fretboard (which is the easiest in my opinion). You can either access the truss rod at the nut end or body end of the neck. Your choice.

If you want a vintage-style truss rod you'll have to make a jig that routes a u-shaped channel in the neck. Just type "truss rod routing jig" in the search bar and you should find pics/tutorials, or ask someone here. I've only routed straight channels for two way rods so far.

Do a search on some forums for building a neck, that should get you pretty familiar with what order to do things. Just make sure you think it through and make sure everything will work right, for instance, routing your neck to shape with a template before you carve it. Little things like that make it easier to keep things precise.

Actually, I'm going to go with the JB/SH-1 '59 combo because I just found out that that's what the charvel san dimas comes with stock. Plus, I've just heard too many good things about both of these pickups. They say the JB is literally one of the best humbuckers ever made, period.

Let's just go with "most popular".
We could argue about what constitutes "best" for days.

Wait wait... I said THEY SAY!!!!! Lol

...And hmm... I wonder why its the most popular. Could it possibly be because its the best all around pickup ever made? :mrgreen:

I don't think you'll be disappointed with those 2 pickups.

I doubt they'll dissapoint. I've heard good reviews of them. I've never used them. I did listen to the sound clip on the SD website and they sound very similar to my duncan distortions. EQ is almost identical.

Hey guys, no pictures yet sorry. Don't have the luxury of internet in my house.

But I did want to update with some news.

First of all, I'm almost done with the body. Everything is looking good except for one area where I screwed up pretty bad. And that would be the bridge cavity. The thing I realized is there's not supposed to be a cavity where the bridge goes on a san dimas. I made it recessed like my other guitars, and I did a very poor job too. It looks like crap. Its not uniform looking and its just very bad looking. Plus, I made it too big and there's really no room for sanding it or fixing it. Not that sanding would help it, it usually just makes it worse.

So I spent hours pacing around the work table today, glancing back and forth at my guitar from different angles. And I decided I wanted to fill the entire cavity with some kind of putty and sand it down so there would be no cavity there anymore. So that's what I did, I went and got some elmer's wood filler and filled the entire bridge cavity with it. It is downstairs drying right now. This was probably a horrifyingly stupid and costly idea, but its done. I figured I could still drill the studs into the wood if I go deep enough (which I think I should be able to), and just recarve a hole for that bridge piece after the stuff dries. I think that stuff might be strong enough for that bridge to sit on top of as long as the studs make it through to the wood. Then it shouldn't be a big problem. The trick now would be sanding the thing to where it is level at that area.

Oh yeah, and I found a custom painter who agreed to let me use his stuff. So not all bad news.

I promise the pics will be up this week.

Eli, I wish I could tell you that I don't think you'll have a problem with your fix but...

I think you're gonna have problems with it. First wood putty like Elmer's is meant for smaller patch jobs. With large holes you will get shrinkage, cracking and adhesion problems unless you slowly built it up layer by layer. The problem is the outermost portion will dry before the inside, so as it slowly dries on the inside (if it ever does) it will lose mass and pull on the already dried outer part of the putty. I would expect it to fail before too long.

Second even though you could use a body filler like bondo, there's a great likelihood that you'll adversely affect the resonance and therefore the sustain of your guitar. Putting a disimilar material to wood so close to the bridge would likely have a dampening effect, though I don't know enough about tremolos to say how much.

My advice would be to cut out the middle section of the guitar and replace it with new wood. It sounds extreme but I really think that would be the best thing for strength, quality, and stability over time. I'm sure other guys will chime in...

The only reason I thought this might work is because the floyd rose is a "floating bridge" which doesn't make much contact with the body at all. So the resonance thing might not even be a big problem. But I'm still thinking of my next move.

Actually, I'm probably going to just scrap the whole thing and throw this guitar in the trash. I don't think I'll try to build another one either. You guys were right.

I wouldn’t let this stop you. We don’t have pics so we can’t see where you are, but you can always remove the putty and move forward from there. Post a pic of what you have when you are done, and tips will come.

Worst case is you have a good bit of practice for your final work on another blank. John's idea is a good one. You are painting the body so it won’t even show.

I tend to do quite a few mockups as practice before I move to my final wood. Nothing special, just some trials to make sure stuff is going to work.

Hang in there.
