I'm working on an carved top guitar, my first carved top, and I just need some pointers. I have a basswood body that im glueing a maple top to, and I dont know if I should cut the maple to shape before or after i glue it? Also, what methods and tools should i use to cut it and figure it? Any suggestions would be very helpfull! |

Just be warned you can no longer get a wagner safe-t planer, well not that you cant get one, but they have been discontinued. Chris's video is very good though, you can accomplish the same thing with a router and a 1/2" bit, I do this and just step it up 1/16 - 1/8" with each pass upwards to achieve the same stair step topography look that Chris does in this video, then I use my DA sander with 60 grit to do the inital shaping. |

Any suggestions would be very helpfull! Here is a thread on my first and only carved top guitar. I did shape the back, but left a little overhang on the top and trimmed that back with a flush cut bit. One thing that I would do differently is to make a set of cross section templates - I pretty much just carved to what looked and felt good. http://acapella.harmony-central.com/sho ... Paul/page2 Think about how you are going to do the binding - the recurve is a difficult area to index off of. Also, don't forget to get every internal cavity routed before you glue the top on - I forgot the hole for the ground wire to the tailpiece stud and had to drill it after the finish was on. |

I use a 5" automotive disc sander installed in my hand drill. That with a 40 grit coarse PSA disc, and it gets the job done very well for all of my carves - tops, neck, and neck to body joints. I personally have found that I never wanted to commit to specific carved design and just kept going until I was happy. |

Generally speaking, it's easier to glue it on before carving rather than after. If it were an archtop acoustic, then you would have to carve it first. I usually use an ibex palm plane for the majority of my carving. I don't do the step method, probably because I just never did it. Another similar method is the "drill" method where you drill down a certain amount. It's somewhat safer than the step method because it's a little more controlled but doesn't remove as much material. It mostly just acts as a guide...when the holes disappear, you're done. The step method really removes a good deal of waste very quickly. |

I've never done a carved top. I am building an ES 335 inspired guitar for a friend soon though, and I plan to simply use a rasp among other files to get the job done. Probably really dig into it with 60 grit on an orbital as well. |

Probably really dig into it with 60 grit on an orbital as well. Oribtal sanders are good for smoothing stuff out, but not very good for carving. A rasp will also only let you do very, very, very limited portions of the top due to geometry. Angle grinder, plane(s) and/or gouges are your friends here, with a (french curve) scraper for the recurve. It's not really difficult, but using the right tools will help a great deal. Don't get me wrong, I love a good rasp, and use it for tons of stuff. But hardly ever at all for carving tops or backs. |

One "rasp" that will work (if you really want to use one) is one made from 8 or 10 old hacksaw blades (or, as mine, lengths cut from an old bandsaw metal cutting blade). Alternate direction, then bind together at the ends. You can bend it like a card scraper for the concaves. I use it a lot for necks as well. |

The guy that I first learned from regarding carved top instruments made mandolins and archtop autoharps! The way he carved his tops and backs was using a stiff but flexible floor sanding disk--about 30 grit--mounted on an arbor. Worked great for him, but I never got the hang of it. He could do a nice recurve and everything else using this method though. I think it just goes to show that the tool is secondary in importance to the technique... Dave |

I've done some forearm, tummy & thigh contours, with a few orbital sanders. I settled on an available-at-Lowe's Dewalt that has an adjustable rotate speed from 0rpm to.. whatever. It's almost perfect for this, for me. With standard oscillating, full-speed spin units I just burn through wood so fast I can destroy a contour in a heartbeat. Having that 0rpm option means the oscillating is the only action and allows me to go slow and precise. And I prefer the smaller 5" discs. Not a fan of the velcro though, I can't get crisp corners like I'd like. :/ Probably my only grievance. |
