Re: high neck relief in an old Regal Parlor guitar

Wouldn't the traditional answer be a compression re-fret (installing frets with a wider tang at strategic intervals to reduce the bow and thus the relief)? Not something I've done myself, but I've read about the technique, and it seems that if you go slowly, checking regularly, it should be manageab...

Re: bridge placement

All the ukes I've made need some compensation on all strings. For a tenor, I'd estimate 1mm or a fraction more for the high A, probably 2mm for the low C. If you plan a low G, then maybe 2.5mm for that. But those last two numbers might be 1.5 and 2mm. I don't try to get the compensation exact in adv...

Re: Sentimental violin repair.

I forgot about the button - told you I don't have experience with violins! It looks to me as if the neck joint is loose, and only held on by the button. Is that right? If so, I'd start by dribbling a tiny amount of water into the neck joint from the top (wipe it off the top immediately) and then gen...

Re: Sentimental violin repair.

Rather than working glue into the crack, I suggest you remove the neck. Gentle heat (hair dryer) plus a tiny amount of water dribbled into the joint - 1/4 teaspoon max - should make it come free. The wood needs to be warm right into the joint, so it might take 10 mins to warm it through. Keep feelin...

Re: Sentimental violin repair.

I make simpler instruments than violins, so read this post accordingly. I'd suggest that if you do not already have quite a bit of experience making musical instruments, you will struggle with this even if you have fine woodworking experience. The risk is that your restoration will not play properly...

Re: Help w cracked to repair from drop

This is what I'd consider in your position, i.e. I bought it for myself and want to get it stable and playable. The problem is the cross-grain crack in the spruce top, so that the top is no longer connected to the lining at that point. So I'd plan this (then ask advice and think about it some more b...

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...

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...

What kind of strings are you using? Before you run yourself in circles chasing measurements, try replacing the offending string.

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 ...

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.
