hello everyone, My name is Geoff Burghardt, I'm new to the group here. I wanted to share my latest mandolin with you all. It is my 10th, and was done for Red Rocks Community College in Lakewood Colorado where I will be teaching mandolin building starting in the fall. I am looking forward to learning and sharing a lot here. Thanks for having me

Hi Geoff - I just posted in another thread asking if anyone has any tips for carving my first top and back for an A-style mandolin. How do you go about it? |

[QUOTE=ecklesweb] Hi Geoff - I just posted in another thread asking if anyone has any tips for carving my first top and back for an A-style mandolin. How do you go about it?[/QUOTE] Hey Jay, First I highly recommend Roger Siminoff's book, bluegrass mandolin construction (or something like that) if you don't already have it. He could answer any question you have during the process. I think good planning is the best way to do anything. I do it like this: Draw concentric circles from the outside edge of the top or back (I usually call them plates at this stage, not sure how correct that is) about 1" apart until you get to the center. These circles, or ovals depending on your body shape, will be lines of equal depth while you carve. Now select the profile of the arch you want on your top and back (usually about the same, except for near the heel)(I use a drawing from the back of Siminoff's book) and figure out how far down each of these equal depth lines is based on the profile of the arch, from the top of the wood. Now rout along the lines a consistent depth, getting deeper near the edges, and deepest about 3/4 - 1" in from the edge of the rim on the outside, and deepest in the middle getting shallower toward the edges on the inside. Let me read that to make sure it makes sense. Maybe a picture will be better 
 
If you have more questions I'd be happy to help. Good luck! |

I forgot to add that once you have it all routed, the carving is just connecting the lines. I have a #5 sweep 1" gouge and a mallet that does most of the dirty work, then I smooth that back with a wider sweep gouge. then once you've connected the lines, come in with a light touch on the chisel or a small convex plane and get your graduations. Then scrape like a banshee. That's the way I do it, I know there are many variations and some of those may be easier or harder. One thing I can say, this is a lot easier than doing it completely by hand (which I do recommend trying at least once). |

Great to see you here Geoff! I'm one of the lucky ones who got to play this Mando last week. I'll also be taking his Mando building course in the fall. I'm really excited about it. Maybe we should post pics of our build next semester. Could be fun for the rest of the OLF to follow along. See you soon Geoff. Also, I fixed my intonation problems on the Bouzouki, I just lowered the bridge and saddle and that took care of it. Plays beautifully now. Thanks for the suggestion. Tracy |

Welcome to the OLF Geoff, Exquisite mandolin you have there!
I'm a bit of a mando player myself and building them is also on my project list so thanks for the info you have shared and i will stay tuned for more input on mandolin making from you!

Geoff, I hope we can look forward to more posts from you. I have the itch to build a mandolin myself. Thanks for the carving tips. |

Welcome Geoff Very nice work on the Mandolin. I particularly like your burst! Interesting and clever way to start roughing out the arch on the back. John |

Geoff, Great job on the Mandolin. Now, I'm torn...between making another guitar or taking your Mandolin class. Thanks for the inspiration. Cheers,
