I have glued my sides together in a mold and all appears ok,but when I take the body out of the mold the shape of the body is a little out,Is this normal or should the body have kept its shape.It is a OM model guitar.My mold I got from guitar jigs.com and it is very nice. Im new at this and any answers would be thankful.Bill |

Hi Bill, Welcome to the OLF! Your rims will flex until you get the linings, or Kerfings installed. It will be a bit more rigid then. Its usualy a good idea to leave your sides blocked in your mold until after your back and top have been glued on, this will help to insure that your sides stay perfectly vertical to the top and back. Hope this helps  |

Thanks guys,I am learning as I go ,I do have some reference material to go by.The one thing I didnt do is when I shaped my front and end block I kinda did it by eye(trail and error) maybe I should have done the pull sandpaper tecnique.Oh well alls ok except as described as above.Thanks......Nice guitars Lance! |

I agree with Hesh. I use a turnbuckel system like this

for several years I used 1/4" fiberglass rods in an aluminum tube with a simple compression nut setup for tensioners (is this a word  ) between the cauls. In fact it has been only 6 months ago I switched to turnbuckles

Bill, If you are using the LMI kit I assume it came with my instructional DVD. I show a nice spreader made from a wing nut, aluminum tube and threaded rod. This will help the sides conform to the mold correctly. Nice guitar so far. Good luck! |

Bill, your bracing is very neat!

Bill your bracing is very neat and clean. You could never get a job at Gibson. I have seen some of their old top brace jobs. Lots of squeeze out and smears on the top's. I guess they figured if you cant see it it doesn't hurt. Keep up the good work. |

I did use titebond for the two main X braces but I didnt like how it dries yellow then I got the glue from LMI that dries clear ,Its a polyvinyl glue that I really like.Thanks so much,Bill |

Ok I see,I think I may have a problem with my front block,When I did the slight radius on the glue side I did it by using a sanding block and would check it for fit. I think it might be slightly off in alignment,maybe I should have done a pull sandpaper teqnique.How do you make sure the front block is in proper alignment? (lateral) so when the neck is attached it centers up in the bridge area?Thanks Bill...... Nice set up hesh,Did you use a band saw to make your body blocks. Heres a pic of my back 2006-07-08_071928_gu itar2.jpg"> |

Here's what I do. 
I saw something like it somewhere and it stuck in my memory. I think it was a Huss and Dalton thing. It seems to work pretty good! Brent |

Hey Brent, It looks like you're doing something I contemplated for a while: Is that mold mounted to a stand, so that the whole thing can be flipped over, top to back to top again? It's a cool idea, and if that's what you're doing, some more pix would be great. Steve |

Where does everyone get their forms? I'm liking the forms. I've been using the plywood with movable posts, but the forms look more sound. Art |

Steve -Yes I mount my molds on this stand. I designed it so I could glue linings on one side then filp and glue the other without waiting 
I have six different molds so I made it ajustable 
This is how I mount them 
I also found it useful for gluing tops and backs. 
I also learned I can "drive the bus" on it!! 
Art - I get my molds from Home Depot
