    Re: Recurve too thin?

    0.009" is almost paper thin, I guess you meant 0.09"... That's around 2.3mm and IMO close to dangerous zone. I wouldn't go under 2.5 mm unless the piece of spruce is extremely stiff. But if you left...

    Re: Tone-Gard Alternative

    Nice one. I've seen similar by E.Kristufek (Czech maker) but he used bent stave and for simplicity just two woodscrews into mandolin. I know that mandolin was experimental one so he just included the...

    Re: Truss Rods vs Carbon Fiber?

    From the little I know, the threads should be designed so the nut held by certain number of threads (I guess the common size of nut is dictated by this) will be as strong as the rod which they are...

    Re: Truss Rods vs Carbon Fiber?

    I've been using simple adjustable rods from my first build and don't think I'm going to change that. I still have my first mandolin and never needed to touch the truss rod. But if the time comes I...

    Re: Mike Marshall's Loar?

    Like most of the best players the sound is in his hands and whatever mandolin he plays (and even mandola or m-cello), his didstinctive attack and tone wins over the instrument.
    His Loar has been...
  7. Re: Tips for bending/fitting the F5 bottom point rib piece?

    I do like John and usually bend the very end of the longest rib a bit more curved so the offcut will fit the point block.
    But I glue the rib piece to the block before assembly. Then I trim the rib...

    Re: Catalyzed Varnish Repair

    Agree with Greg.
    You may want to steam the dent before filling. Have a look at frets.com on repairing dings. Frank mostly fills with thickened nitro but on many catalyzed finishes thin CA is the way...

    Re: Slotting a nut

    My slots change direction both when viewed from front and side. The curved surface allows for that tiny amount of change. On mandolins it is really not much and most folks would not notice at all,...

    Re: Measuring Humidity... What's a Guy To Do?

    Re: Slotting a nut

    It is possible to cut curved slot on nut. It's not flat and not parallel to anything (at least on the instruments I worked on)
    You need to shape the top profile of your nut so it copies the future...

    The numbers are certainly 1's not 7's here in central/eastern Europe that's the common shape of 1. It's different from US font 7.
