    Re: Instaalling frets on a new build

    I like to press in frets using a fret arbor press and caul. I get a more level and cleaner installation this way. Typically, I don't have to do much fret leveling with a good fret press job. When you...

    Re: Is this good for braces?

    That looks like a piece of spruce, but possibly European spruce? I went to the website listed; binderholz.com. The company seems to be headquartered in Austria? PEFC also seems to be a euro-centric...
  3. Re: Thoughts On Hairline Back Seam Cracks In The Tail Block Recur

    After a bit of research, I looked at my records on the construction of my mandolin. I had actually left an old fashioned lightbulb too close to the lower back seam. It became hot and opened up a...

    Adrian - Seems like a logical explanation, but these instruments have likely never been exposed to humidity below 35-40%. I live in the southern United States where low humidity is never a problem...
  5. Thoughts On Hairline Back Seam Cracks In The Tail Block Recurve

    I searched the forum for past posts on this subject but didn't find anything.

    I have a couple of mandolins that have hairline cracks in the back seam in the recurve at the tail block area. One of...

    Re: Can anyone identify these tuners?

    On second look, the shafts, especially the Ds and As seem short. Maybe the shafts have been modified? Here's a photo of a nickel set of MF40R tuners.

    Re: Can anyone identify these tuners?

    Those appear to be Gotoh MF40R tuners. I know that Gotoh has different style/color buttons, so they should be easily replaced. However, I don't know of a source for buttons only. Here's a link to the...

    Re: What brand tuners are these

    Andrew - I'm guessing you're not a fan of the Gotoh bushings either. I like the tuners, but their bushings are a bit large, high, and rounded above the surface.

    For years, I used a hot pipe heated by a propane torch. While this worked well enough, my pipe would have an uneven heating surface with hot spots where the flame was closest and cooler away from the...
