  • Benn, I can only speak from my own experience, but I never use a temperature hotter than 240 degrees F. While there is occasionally some water spotting, I don’t get staining that doesn’t easily sand out. I also use distilled water, and of course the sides are wrapped in new aluminum foil.

    Scott,

    I am certainly no expert on the technical aspects of cnc. However, i have been running cnc’s to aid my guitar building a long time, and over the years, I have owned 3 or 4 different Next Wave machines. I was always able to cut perfect circles. That said, early Next Wave machines were no the most heavy duty things. The best thing I found about Next Wave was great support. I bet you have a worn part, or something like that, and next Wave support will be able to help you.

    Here is a spectrogram on a Big Hoss guitar we have for sale at Dream Guitars. Pardon all the braggadocious labeling. It’s marketing. We are trying to sell it. However, all the statements are true, and I believe this to be a really good guitar. I would not have added the labeling just for a post to this forum.

    I am shocked by how active the back is on this Martin dread. How does this guitar sound? good, bad, great, fair, average?

    Karl, I find many guitars with 2 cross dipole peaks close together in the area you are wondering about. That includes all Lame Horse Big Hoss models, although they are spaced out just a bit more. Why? I certainly don’t know, and no one else does either, but from doing Chladni patterns, that is what they are, at least on Lame Horse guitars.

    Paul,

    We use a lot of vacuum to do all of the tasks you mentioned. I have found almost any pump will work, some just work much faster than others, some run much more than others. It is pretty easy to find medical surplus vacuum pumps around, and I have found all of those acceptable. If you can put a fairly large reservoir between the pump and the bag, table, or whatever you are needing to pull a vacuum into, it can compensate a whole lot for having a pretty small pump. For glue ups laminated tops, sides, bridges, etc, it does not take near as large a pump as it does for something like a vacuum table for a cnc. A small pump will hold a guitar on a vacuum work fixture.

    All that said, buy the biggest one you can find and afford. Hook it up with the biggest reservoir practical. Use the instructions at: https://www.veneersupplies.com/pages/DIY__Vacuum__Press.html to make the system turn on and shut off at your desired amount of vacuum (you can have too much vacuum). These guys sell everything you will need, including fittings, gauges, bags, etc.
