Re: Banjo neck angle

I'm informed these were gut strung instruments with a much higher action than on modern banjos. There are experts on the Banjo Hangout site who could help.

Once you decide on bridge height and action height, you work out the neck angle from that. I doubt anyone can give you a number for this.

Re: Banjolele with holes in skin

I'd patch those holes. Ideally with scraps of vellum, but if you can't get those then something like heavyweight art paper should work. If you use hide glue, you could easily remove your patches if you later found better material. I'd patch the underside without slackening the tension. Once glue is ...

Re: Banjo Dowel Stick Angle Adjust?

Are you sure you need to remove and reattach the dowel stick? I think it would be more normal to change the attachment position at the tailpiece end - assuming there is a screw from the tail into the dowel stick, drill a hole in the dowel stick end at the correct place for your desired neck angle an...

Re: maple neck - use different finishing for neck and fretboard

Tru Oil has worked nicely on necks I have made. However, it is not very resistant to abrasion. On a fretboard, fingernails often dig into the surface, and I think Tru Oil would soon wear away there. So I'd choose a polyurethane varnish, and a hard one, for this fretboard. You could thin it to make w...

Re: Restoration of a 1931 Martin 00-17

Glad I got it right describing fixing gaps in HHG joints! I am a rank amateur by comparison with many on here. I've no experience using fish glue, but I've read a lot about how it softens with heat and moisture. So the same principle ought to work here. But it's not my own instrument, maybe I'd do a...

Re: Tenor ukulele neck replacement

Don't forget that you will need to change the bridge location to suit the new scale. Concert scale is around 15 inches, while tenor is around 17 inches. So your bridge will be approximately 1 inch nearer the tail than if you fitted concert necks. This is probably OK - you might lose some volume and ...

Re: Please help: neck reshape: yes or no

I'd expect the neck wood to have changed colour because of light exposure, and so I'd remove all the finish on the neck shaft (a) to get a uniform colour, and (b) to avoid visible lines where new and old finish meet. However, I think you might get away with feathering new finish into old at the heel...

Re: Ukulele Intonation Mystery

What kind of strings are you using? Before you run yourself in circles chasing measurements, try replacing the offending string. I recently installed a new set of Aquila brand Nylgut strings on a 5 string banjo. One of the brand new strings just would not play in tune. Checking the intonation, I fo...

Re: Ukulele Intonation Mystery

Something is wrong with your build, though I can't work out what from your description. On a soprano uke, C string total compensation is a little under 3mm (1/8) using Aquila Nylgut strings, and probably under 2.5mm using fluorocarbon strings. (calculated from 2 x nut-12th distance) For a concert th...

Re: Need a method for easy/reliable top/back removal

I'd use the paper shim and attach it with hide glue. When the top is removed, a warm damp cloth should pretty much wipe away the paper on the rims, and you don't need to clean all the hide glue off because it will reactivate with fresh glue. I suspect liquid hide glue would work for this, though I u...

Re: Ukulele

You'll have to decide what size you want to buy - soprano, concert or tenor (baritone is rather a different beast, more like a tenor guitar with nylon strings). And that will depend on what you want to play. If you're looking to do strumming (which can be quite complex), semi-percussive playing and ...

Re: Weissenborn Dead string

Assuming that your friend is playing with a steel, then the only thing I can think of which would affect just one string, and for most of its length, is the saddle. Two possibilities: 1. There is a small void at the base of the saddle slot, or an imperfection in the base of the saddle, under that st...

Theres a post in this thread which has useful links - they're making model sailplanes, but same technique. Plaster seems to work for small production runs.

Nice work Chris, I wouldn't have picked up on the MoTS fretboard if you hadn't mentioned it. A quick question if you don't mind...

Re: Hybrid design question

Calculating my archdukes it somewhere between a 6' and 8' radius, rather more than I'd guessed. Am I right that floating bridge instruments experience less "folding up" stress because the tailpiece directs the string tension in line with the neck and sides, rather than via a fixed bridge which wants...

Re: A few questions about the mandolin family

1. Tradition. But mandolin and violin are strung at the same pitches, and quite a few players play both, so that might explain the similar neck width. 2. Don't know, but why not? 3. Some mandolins do have radiused fretboards, but on a narrow fretboard the radius makes much less difference to playabi...

Caley, guitars and mandolins use the same wire. Just different lengths/diameters (and different ends to fix to the bridge or tailpiece). So my table might help you here. From your post, your shortest string is about 7 inches and is an E. The table suggests that (for acoustic guitar tension) an E str...
