| Post subject: | Quick X-brace question |
Hi guys I've just finished the X-brace for my next 'OM' project. It is joined, radiused and capped but not shaped or glued yet. I've just noticed that the height of the brace is 4/8" and not 5/8" like i've seen recommended on this forum. Will this make a difference? I think probably not but I have no idea, hence this post. I don't want any problems with this guitar. So, can I carry on and use this x-brace or shall I make another?? Many thanks Mat |

If it were me I'd redo it since it's not going to harm anything by not using it... like trying to remove it from the soundboard might. Don't ask me how I know ![[xx(]](./images/smilies/smiley11.gif "Dead") Plus you get extra practice to learn to do it right. Just leave it a little tall before you radius it and afterwards, if needed, it should be easy to sand it down to the correct height from the top of the brace. I won't comment on whether 1/2" is safe or not. I'll leave that for someone with more experience. |

Boy those look higher then 1/2". Did you check your braces for Run Out? Why the double cap? I just did my first braces so I'm new to this too but I think the stiffness of the braces would also be a factor too and weather or not you scallop. I'm interested in hearing the answers to this too. And also why please. |

Chris The brace stock was bought already cut to size from a respected Canadian seller on Ebay. I believe his wood is good quality so I'm assuming no runout. I have no idea why the 'double cap', I just thought that was what you did,

You know what they say about Ass u me don't you. One thing I learned from a discussion over at MIMF which was excellent and too bad it's down now is that the only way to tell about run out is to split a piece. I don't care who it's from! But that's your call. It's your guitar. I got some and the discussion here is still up and it was terrible. I ordered some billets from someone else and still cut a brace off the end of each billet and split it to check the run out and tapped it to the side of the billet so I could see how the run out was in each billet. There was some with no run out and some with run out that I can get shorter braces from. I also got a 2 X 6 from Lowes that I'll get many braces from. |

1/4 wide by 1/2 tall is fine for an OM with light gauge strings .. meds would be pushing it, although good for DADGAD tuning. |

Just an example: The top edge of the 2 X was split then planed to work from that edge. $6 for the 2 X 6 X 8'. |

1/2" is lower than I would go. That 25% increase in height (to 5/8") is going to almost double the stiffness, other things being equal. |

What? I was napping.......  IMHO 1/2" is not only fine but preferable. The 2 OMs that I built in 2007 both were 1/2" at the X-intersection prior to capping and this is with 1/4" wide braces as well. I had to make sure I spelled capping correctly.......  I know a superb builder who will go lower than 1/2" too but I have been too much of a chicken to try that. I think that you are good-to-go. ![[:Y:]](./images/smilies/smiley20.gif "Thumbs Up")

Examining a 1983 Olson SJ I was amazed to read 1/2 inch height on the x-brace join. It's holding up fine and had medium strings too. I build mine at 5/8, but I think you could safely go lower, which others have proven. Mmmm hmmm. Good question.

Thanks for the response guys. Think I'll stick with it. I generally string up with Lights anyway so it should be ok. Mat |
