Shaping and Scraping

Ok... My camera is giving me shit so if you're just here for the pics, this is all you get:


So there you have it. That's the body of the cheapo guitar cut to shape and routed. I used pretty much the same method as I did on the baritone body. The only difference is this time I frakked up the glue joint between the two pieces of wood so the top of the thing wasn't quite level so before I started I put some eighty grit paper on my random orbital sander and whirred it across the top and back a few times. Worked like a charm. I used the same template as I used for the baritone body. I like it and just can't think of anything better.

First thing I did was trace the outline on the body and do a rough cut w/ my jigsaw. Last time I tried to use a smooth cutting blade and get as close as possible, which worked OK. This time, I just went ahead and used a fast cutting blade and stayed about a half inch outside of the line. If anything, this method left me w/ less wood to cut away during routing--and it must have saved me fifteen minutes or a half hour w/ the jigsaw. Of course, it could have just been the fact that I have greater and more substantial jigsaw skill now but I really do think this was the better method of doing the rough cut and will continue to use it in the future.

After that, it was a simple matter of routing. I set up my template follower to cut a sixteenth of an inch outside the line and am glad I did. There was a little bit of tear out but, unlike last time, I left some extra wood. Once I was done routing, I just took my trusty random orbital sander and sanded down to the line.

So far, I must say this is head and shoulders above the first one and I think I'm gonna buy a nicer neck than I originally planned. I like the kinda weird streaks on the cheapo alder I'm using and I think this one will be nice enough just to finish w/ a couple or five clear coats. I'm thinking I will get a tele-style neck w/ a maple fingerboard and it will look really simple and classy. Probably go w/ chrome hardware and chrome-covered humbuckers. The only weird thing is it's gonna have about six knobs because of the electronics I'm gonna cram in there.

The Hall of Shame

Yeah. The rumors are true. This is the first guitar body I've built and the first real woodworking I've done in my life so I fucked a thing or two up. Nobody's perfect. What can you do? Well--I'm gonna outline the mistakes I've made in the hopes that doing so will pound them into my head to such an extent that I do not make them again.

The thing that pisses me off the most is I did a round over along the edges of the little nub that sticks out for the neck pocket. I wish I had taken a picture but what happens is that the edges of the metal plate that goes on the back stuck over the edges of the round over just a little bit. I suppose the issue is mostly cosmetic since the joint still seemed sturdy but irritates me just because it wasn't caused by my lack of skill but simply from lack of thought. I probably didn't need to do anything but just for the sake of learning how, I filled it in w/ putty. The stuff I used is called Plastic Wood and fit the bill nicely in my case because it's both drillable and stainable (though it's pretty much impossible to get any kind of filler to match the wood). First I had to build it up w/ a putty knife (in layers so it dried right):


Then I sanded and shaped it with my random orbital sander and just sanding by hand (you can also see another little fill in the lower right):


I redrilled the hole in the upper left after this picture was taken. There were also some minor tear outs from the router that I filled in while I was at it. In the picture below, you can also see the filled-in gouge I made by carelessly lifting the router off the template before the bit stopped spinning. A moment of distraction can really cause a lot of grief in the end.


I didn't get the control cavity quite right so I ended up having to build up some little nubs w/ the Plastic Wood so I could drill little holes for the screws that hold the cover on. I'm not really worried abut these being too strong. Basically, I just want them to hold the screws in for the sake of appearance. I figure the two screws that can go into the actual wood will be plenty to hold the cover on.


These ones are small but they still tick me off because they were caused by carelessness. You can barely see them in the picture but there are a couple small fills there. One is by the pickup cavity and was cause by me marring it w/ the chuck of the drill when I was drilling the hole to the control cavity (which reminds me, I still haven't drilled a hole for the bridge ground). There are also two little crescent shaped ones on the bottom of the guitar which were caused by me not putting anything in between the guitar body and a clamp at some point in the building process.



There's also a couple tearouts just caused by my inexperience w/ the router. I'm not too mad about these--you gotta learn somehow--but they are still ugly no matter how you count it:


I'm using a dark stain on this and so far it looks like the fills are going to be fairly well covered up (though the finishing processes is proving to be problematical in its own right--more on that soon). Still, I have a lot of work to do if I want to start doing more natural finishes and I don't want it to look like crap.

Some Sanding

We had some nice weather today and the best way to celebrate such good fortune is to go out in the back yard w/ a hunk of medium density fiberboard and a random orbital sander. I can always find some work to do on my fiddles when I have a little time and the opportunity.

I ran into my landlord while I was working and was pleased to find he was totally cool w/ me using powerful implements of electric destruction in the back yard. I didn't ask before I started because I was afraid he might say no and then I wouldn't be able to build guitars. (Besides, nobody tells me what to do.) His wife hates me for some reason though, probably on account of my hair being so much more stylish.

My task for today was to shape the two templates a bit so they matched better. In hindsight, I should have just shaped one template how I wanted it and then used that template to make the other but that really makes too much sense for me to figure it out the first time around. Instead, I just cut them as close as I could w/ a jigsaw and now I'm going to have to spend a couple hours making them match.

One thing that's cool about the Workmate is that you can flip up part of the surface so you can clamp stuff to it sideways (this thing is really proving quite versatile):


You can see from the picture that I had quite a lot of work to do though it went surprisingly fast w/ the power sander. I just had at it for a couple minutes at a time until I had the edges reasonably well matched:


I realize now that I made some mistakes when I was cutting out the templates w/ the jigsaw, the worst one being I tried on one to line up the pattern really close to the edge of the board so I wouldn't have to cut out quite as much. This lead to one of the templates having some flat spots around the edges that made it a real bitch to match to the other one. Ultimately, they ended up slightly smaller than I had originally intended.

I also could have saved some time had I had the forethought to get another sanding disk for my sander. By the end, it was really too worn out to do much of anything:


I should have replaced it before it was half this bad. Had it been the actual body I was working on, I would have stopped but since this was just the template and I didn't mind if it got a little scratched up, I pressed on, figuring the time saved by replacing it w/ a fresh one would be less than the time it would take to walk to get another.

Now, all I have left is around the neck pocket and inside the horns, which are still looking pretty gnarly:

For this, I need to take a trip to the my local home garden warehouse to get a drum sander, unless I want to do it by hand (and I don't want to do it by hand, I assure you). It should take all of fifteen minutes and then I will be able to do a little more work on the body. I do still need to get the control cavity, pickup routs and neck pocket done on the templates as well. It will all be done in time one way or the other.
