Post subject: | Go Bar Length?? |
I have a GB deck I bought awhile ago. It is non adjustable for height. The go bars I got with it are fiberglass rods cut to length for that fixed height. I now am using radius dishes composed of two thicknesses of mdf, so they are 1 1/2". My question is are my go bars now too long? Seems to me they might make too much pressure now. Anyone have a formula to measure the pressure relative to go bar deflection? |

There was something a few weeks ago. If I understood it correctly, for a given go-bar material, once you've flexed them a little bit, the pressure remains unchanged until you've bent them a ton. The farther you bend them, the squirrellier they'll get though. Make sure you wear your goggles. Mike |

If you got that from Blues Creek you are fine. The standard length is 21 1/2" about the same as the opening . I brace on a 1 " disk with the same go bars you do and they work. You need to have about an 8 to 10 lb force |

No I don't use a gobar for gluing tops and backs , I have a press. |
