    Re: What the heck just happened?

    In general, you should try to keep your shop at around the middle of the RH range in which the instrument will be used. I used to be pretty fastidious about keeping my shop at 40% RH. Now I try to...

    Re: kermin mandolin

    A Labraid Grand Concert, or something else by Brian Dean, is going to be the closest thing. The construction of the Grand Concert is similar, though it doesn't have the "chimneys" which connect the...

    Re: binding channel cutting options

    They are called Torque Reaction Arms. You can go onto vxbbearings.com and get the bearings and a shaft for cheap. The commercial models are $700+ unless you find one as surplus.
    They do a lot more...
  5. Re: Cleaning Mold From Inside a Guitar?

    I would go with UV light, once it's dead, it's dead. There may still be some below the surface, but anything that would kill that would be bad for the glue joints or finishes.
  6. Re: Source for single Thomastik strings?

    I got some from JustStrings or Strings and Beyond at one point. Never again since the price for a set of A strings was about half the price of a full set. I'm not aware of a source for single...

    Re: Storage: Case vs Hanging on the Wall

    Instruments I collect are in the case, in a closet. Instruments I play are on the wall .. otherwise, they don't get played. I have three rowdy kids and no Nerf gun or Airsoft battles have resulted in...

    Re: Alternate cases for bowlbacks?

    If you don't care about it looking fancy, just find a box as Mike suggests. Then fill the void space inside with egg crate foam or similar, then a few bucks worth of nice looking fabric tucked down...

    Re: Soft Picks ?

    Some of the Clayton picks are softer and give a warmer tone. The gold standard is the Wolle soft polymer pick from the German style.
  11. Re: Non-mandolin question (electric guitar)

    I just built a travel guitar with/for my son. It was a relatively quick, easy project, and a good way to introduce him to some lutherie principles. I agree that a Tele or Strat would be easiest. No...

    Re: Mandolin sound changing over time

    Torrefaction isn't the same as aging, and it's not about moisture content. Moisture content equalizes pretty quickly, in a few months after the tree was standing. Then the wood is going to be...
  13. Re: how to get perfect compensation, tool perhaps?

    This should work just fine. Your bridge base will need to be pretty shallow since they're already over 1/2" tall. But if you can get the position and height correct, then your luthier can work off of...
  14. Re: help me out, how to do vibrato on a 4 string

    You can do this with string bending, it just takes practice, and is difficult to do for any more than two strings at a time. For a real operatic, continuous vibrato, you're right, either a tremolo or...

    Re: cnc and or router pantograph

    I like how you can angle your spindle. I am planning to build something like that so I can do sanding on my machine. Then parts will come off without any tearout, which is a big problem in spruce.

    Re: Eastman 515 V - wow

    It's their violin aging process. A lot of people would argue that violins don't look right until they've got a bit of a patina, and a lot of people would argue the same for mandolins, guitars, etc....

    There are scientific disciplines devoted to exactly this - the interaction between humans and things or the built environment, perception, etc. The stimuli (i.e. sound of the mandolin) can be...

    Re: new lesson , (painful) every day

    I had a finish sprayed on a nice mandolin... put it out in the sun to cure. Came back 15 minutes later, the whole varnish had bubbled up looking like bubble wrap. Very sad. We feel your pain.

    Re: Recommendations for a ruined(?) finish

    If you're not going to be spraying a light seal coat, you should use a clean lint-free rag and really burnish off all surfaces and nooks. You want to clean off all dye particulate that's not in the...

    Re: Recommendations for a ruined(?) finish

    Zinsser Bull's-eye dewaxed in a can is basically a one pound cut of blonde shellac which stays good for a long time. If sprayed on very thinly for the first few coats, it will seal the dye in nicely...
