    Re: new top F hole repair

    Irish, cutting something fragile (or is weak along the grain - like wood!) is helped by backing it up with something else and cutting both. Very fine saw blades can be had from modeling supply...
  2. Re: Removing finish spots all over Regal tenor guitar

    First, you might check this forum and other sources on how to identify finishes. You might be very lucky and find that the splatter coat could be dissolved without damaging what’s underneath. ...
  3. Re: What if I removed the nitro finish from the sides of my mando

    I guess fashion and the market determine what’s proper and what destroys value. Extreme in the antique furniture world, where a crazed and dirty finish is vital to resale. Less so with paintings,...

    Re: Bridge Misfit

    It’s interesting. My antiques all have narrow, flimsy bridges, contacting the top at all points, and sitting directly over a brace. My “newer” adjustables have a much larger footprint, with or...

    Re: Convert...

    I have been told that my recent vast uptick in mandolin playing must be a result of the demise of my last cat.

    Re: In Tuneness and Buzz

    I just noticed a new buzz source on my primary mandolin, D strings, and after first blaming the nut a bit, I finally saw that my lowering of the bone saddle on the bridge by sanding the bone and...

    Re: Old Safe-T-Planer, new cutters?

    Mark,
    First, the cutter can be resharpened many, many times. Second, the version I have (unknown origin) uses plain 1/4” square tool bits, (just went downstairs and measured). The bit is ground...

    Re: DePaule Nouveau inlay advice

    General questions: These inlays are hand made, so no templates. Do any of you scan these with a CNC and then use it to rout the recesses? For something this complex, how many labor hours would you...

    Re: Scuff and level sanding?

    Dale, the only non-abrasive Scotchbrite is the ‘aircraft cleaning pad’. Everything else contains (different) abrasive, the white pad 7445 I think is the mildest,, with removal similar to 0000 steel...

    Short grain and scrolls

    Doing an amateur restoration on an 1890s Joe Bohmann bowlback. The end of the headstock is adorned with what Id call a split pediment if it was on a clock, as in the photo of an intact one, below. ...
  11. Re: Quick and dirty electric mandocello conversion

    DVVVDM. Re. Belt sander. These are very aggressive things for anything other than a flat surface, and you could easily make a mess handheld, even with a fine belt. You might try to do the bulk of...

    Re: Al Carruth scraper - Sharpening

    Further beating on this expired equine: The whole concept that you can maintain a straight edge while cross-grinding by hand is simply flawed - at least at the level that might be relevant. You...

    Re: Sorry for this string height question

    Brian,
    A wound string, plus maybe a little abrasive, should work, but the smooth ones maybe not. However, if you have the usual box full of Dremel bits and wheels, one of the very thin disks, hand...

    Re: Neck bowing in an odd place

    Daniel, i think your analysis is valid w/r/t the angle of the headstock. That it’s a design feature is shown by the staple that holds the strings down, but does little about the torque that’s raising...

    Re: Kentucky KM-140 Neck re-set?

    Looks solid! Just to understand it: you routed or cut channels in both parts and added plywood and glue? The insert is a rectangle the full height of the neck? Huge surface in shear which can’t be...

    Re: Al Carruth scraper - Sharpening

    Well, Lie-Nielson can sell you a $45 wallet to keep your scraper in! But seriously, selling specialty tools in very small quantities pretty much forces very high markup. Luthiers are a tiny fraction...

    Re: Al Carruth scraper - Sharpening

    Ok, so I just blew my lunch hour - and then some, trying out variations of card scraper, low-temper tool steel, and really tough stuff. Soft pine, maple, apple. Ground crossways, lengthwise, fine,...

    Re: Al Carruth scraper - Sharpening

    Interesting idea, and I’ll have to try out the concept on an 1/8” or thicker milling spacer, but to paraphrase an obscene saying, anything’s a scraper if you’re brave enough! Although the Carruth...

    Still confused here. Can anyone explain why the neck joint has anything acoustic going on, or why a nice solid nut and bolt would be inappropriate on a salvage job?

    Re: The real glue strength

    Non-builder here. One of the considerations not mentioned so far is that glue strength can be too much. HHG, in particular, comes in different ‘strength’ formulations and I have read that where it...
  22. Re: Help! Quick recommendation - Paasche airbrush

    Dale, I mentioned the cheapie (HF, and others) because it was recently mentioned here by a few folks. I picked up one NIB at a tag sale for, I think, $5 or less, but haven’t used it; only made a...

    Re: Loose tuners

    DWC, if I understand how these things are designed, it’s the string tension that pulls the little gear into tight contact with the worm; hence ‘worm over’. There should be no problem with the parts...

    Re: new bridge for flat top?

    A violin mute just adds a small mass to the very top of the bridge; makes a huge difference in sound - mellow might be the best term, as it kills the higher stuff. You could try something ad hoc...
