    Re: Cutting Shellac for sealing

    Spiritus, as spelled, is denatured. Spirytus is plain ethanol. Dangerously close names. In the mostly lawless US, there are no restrictions on the toxicity of denatured alcohols. Anything can be...

    Re: Exposed Bushings

    If Adrianís mention of a tube wrench means the same as my usage, it also has a gap that would allow the string to remain in place. To me, a tube wrench is a box end hand wrench used specifically for...

    Re: Exposed Bushings

    Pretty clear to me that the whole counterbore (stepped hole) thing is just a way to make things look more important, and to sell counterbores, but drilling straight through from the top obviously is...

    Re: Exposed Bushings

    Jim, from the mechanical standpoint, the rim/lip/flange of the bushing is the right place to be the fulcrum in the lever that’s pulled by the string and held at the other end by pressure against the...
  5. Re: Interesting Mandolin- Cammeyer -the owner from NYC?

    That is an interesting machine. The tailpiece alone should prevent unwanted sound issuing, but would be handy to open beer with. The neck heel is also aberrant. You might buy it and then do more...

    Re: Exposed Bushings

    Larry, since it’s the non-bearing side that interferes, wouldn’t it make sense to make all bushings with a cutaway on one side? Would work on any taper, including zero. Or is that simply too much...

    Did it. Now adjustable action. Given the springy (original skin) head, seemed like a necessity. Now I can buy those tenor banjo strings and make a more or less conventional bridge. Lilac,...

    Re: Half a mandolin question

    Thanks! I was wondering about exactly that. And I assume these are bare and wrapped steel. The other option, Nylgut (awful name) would, I guess, be a possibility, attractive because of lower strain...

    Re: Exposed Bushings

    Human brain issue: Leaving it alone is tolerable to nearly all. Pushing 7 bushings in and having one resist trips a switch in the brain that results in immediate and immoderate application of...

    Re: Half a mandolin question

    All true. Heated the heel and took out the tenon. Several surprises. First, it’s only 1/2” diameter, and the 3 degree angle is machined on the tenon, not the heel, which seems backwards. Then, the...

    Re: New Eastman Octave tuners?

    Coombe is correct that that effect is string sticking in the nut, but can (less likely) be the post sticking in the bushing, or even more unlikely, a bad gear fit to the post. Easy enough to sort...

    Re: Half a mandolin question

    Thanks. I’ll get at it in a day or two. Just might mention that a medium size lathe is also a horizontal boring machine, best a metal-cutting version, where the ‘sled’ only has to be a clamp on...

    Half a mandolin question

    I just bought an antique banjo-mandolin just to experiment with sound, and to have a familiar scale length. Maybe 1900-1920. In fairly untouched condition. The neck has moved upward over the...

    Re: What's your Spraying set up?

    Spencer, diluted paints generally keep fine in a closed container. Of course, not two-part materials that can’t be saved. Just remember to agitate/mix and use a paper/nylon filter again when you...

    Re: Post a picture of what's on your bench?

    Machine age arrives 90 years ago! Shiny! So is there going to be a protective finish, just a wax, or nothing at all? Also, did Alcoa make a press tool for this, or just rely on the (many) skilled...

    Re: Lilac wood

    Surprising question, considering that the electric toaster is a Scottish invention from ca. 1893. I tried to Google what toaster ovens might be called in the UK, but got no significant hits. So, I...

    Except for the toaster oven in flames, it sounds both non-toxic and a good process. Better than the other old-timer recipe which involved soaking tools in used motor oil. In the antique tool...

    Correct about that warping. I made a test spindle, about 3/4x16 rough turned wet, and letting it dry in the lathe, lots of movement in two days. ...

    I've never broken a blade on this saw. When you think about it, 17' of blade does a lot of cutting and the blade only bends and straightens twice during all of that cutting. It bends on a rather...
