Re: ordering plans

Hi Matt, we just had a major upgrade on the software that runs the Forum, and unfortunately the Donate button got lost in the process. We are working on restoring it and the button should return soon. Thanks for your patience.

Re: Inspection Camera

I got a Fantronics wired USB endoscope (also from Amazon, but currently $21) for Christmas. It is about 8 mm in diameter, has adjustable 8-LED lighting, and has a long semi-rigid cable, so it is maneuverable, but doesn't flop around. I just hook it to a laptop, but apparently it will also plug into ...

Re: Ex-wife ran over guitar

Peter, I did an almost identical repair and documented it here nearly 20 years ago. Simply sliced off the bad part and attached a new head. I did have to buy new tuners, but the wood was scrap - cheap repair. First time I'd ever done anything like that, and it turned out great. Have a look: http://w...

Re: Cello Jig

Officially, build questions belong here and repair questions belong in Repairs, but we realize at times the lines are blurry. You will probably get a better response here because of the instrument-specific knowledge required.

Re: "Search user's posts" not working for me

The software that runs the forum was updated a few days ago after it hadn't been updated in a while. The active topics are still showing up color coded for me, but the old icons have disappeared and the color change is subtle. I have heard the old icons and style may come back as the update progress...

Re: Peg shaver idea

That is the standard version. I use an adjustable one like this: https://internationalviolin.com/ProductDetail/t39_peg-shaper-adjustable-violin--viola that can be adjusted to handle pegs from smaller violin to viola size. There is a separate model which handles cello-sized pegs. Both versions work f...

Re: Peg shaver idea

The internal helical cutters of that type of pencil sharpener are usually fixed, and are way too steep of an angle for instrument makers. You would have to pull out the internal mechanism to see if there is any way to change the angle of the cutters. Barry, by 90 degrees do you mean perpendicular or...

Re: 1/10 violin

I have always had good luck with https://internationalviolin.com (and they happen to be local to me). I had a quick look and saw 1/8 and 1/16 size pegs, but I didn't look very hard. My guess is the 1/8 pegs would work fine.

The forum software was confused because the links did not point at actual images.

Re: Understanding flute tuning

You are technically correct that the final end tuning might have to be done at the end. You need to start with undersized holes because you can make a small hole bigger, but not visa versa. The larger holes will effectively lengthen the instrument, so the total length my have to be corrected at the ...

Re: Understanding flute tuning

Before I even get started, in my experience none of these flute calculators is very exact. They should get you in the ballpark, but you always have to fine tune. First, I suspect the bell frequency you are using is way too low. My D flute (~293 Hz) is roughly 22" long. Your 11" E flute should be jus...

Re: Motor help

Sounds like something is shorting out, or maybe the capacitor is shot. If it ever becomes more trouble than it's worth, there is a recall out on most of those old Craftsman radial arm saws and they will pay you $100 to take back the motor. Take the check and buy a new sander.

Re: Pet Thread

The collars are designed to be annoying, but safe. If you want something less drastic, try clicker training. The clicker makes a sharp, loud noise that can be just as effective.

Re: Dulcimer sides

That is exactly the basic idea. My version uses a sanding cylinder with bearing in a drill press, so both the top and bottom are secured, but a 1/2" shaft on a spindle sander is probably not going anywhere.

Re: Dulcimer sides

The drum itself is some kind of rubber, so when you tighten the bolt, it expands slightly to hold the sandpaper cylinder in place. There is a large bearing on the bottom that you fit into a like-sized hole in a baseplate mounted to the drill press table. With the spindle in the chuck, and the bearin...

Re: Dulcimer sides

Too late now, but another good option for thinning dulcimer sides is something along the lines of what is sold as the Luthier's Friend Sanding Station, which is basically a drillpress-mounted sanding cylinder with a bottom bearing and an adjustable block next to it. Very easy to make if you don't wa...

Re: What is it and how can I make it?

Better yet, just put "How to make a cuica" into YouTube. There are a whole bunch of videos on it. This page has some nice closeups of how the stick is attached. The stick, normally bamboo, has a lump on the end. You would soak the head in water until it becomes very pliable, drape the skin over the ...
