DIY Sopranino Ukulele Part 2 – Sides

Thanks to Khai Nguyen on YouTube for the suggestion of using hair curling tongs for bending the sides.

Thinning the sides

I cut two more strips on the bandsaw and thinned them down. They were slightly too narrow to use for the bottom of the uke so I used them for the sides. Thinning the sides takes a while but gets there in the end. I’m aiming for 2mm thick.

DIY Sopranino Ukulele Part 1

Ok – there are lots of things I’m supposed to be doing but here’s another project just for fun. I’ve long wanted a Sopranino Ukulele but I can’t really afford one, plus it would be fun to have a go at making one.

A Sopranino is smaller than a Soprano Ukulele – the Soprano has a scale length of around 13″/330mm and the Sopranino has a scale length of around 12″/305mm. One big advantage of this size is that I can resaw the timber on my mini-bandsaw which has a capacity of around 75mm.

This is the concept I came up with:

DIY Bass Ukulele

Just because I don’t have enough projects on the go 😉 I’ve started making a bass ukulele. I call it a μ-bass.

The body is an old Port Wine box. Since this wasn’t glued I’ve run Titebond around all the joints so they don’t buzz. The neck is a old piece of mahogany that has been lying around for 20 years. I bought some bass guitar tuners on eBay – I’ll need to make the slots bigger. Soundboard will be birch plywood.

Progress so far

Ukulele intonation – compensating the saddle

I bought a cheap Makala pineapple ukulele secondhand on eBay – I couldn’t justify anything expensive. Overall I’m very happy with it – the tone is fine & it holds its tune. However the intonation (tuning) of the fretted notes was poorer than I’d like particularly on the C (lowest and thickest) string.

There are a number of reasons why this can happen:

  • The nut and/or the saddle is too high, so the string gets stretched when you press your finger down. This raises the pitch.
  • The saddle needs to compensate for the thickness of the string. Thicker strings don’t bend and vibrate in exactly the same way as thinner strings so the length needs to be slightly different.

Adjustable compensated saddles are a standard feature of electric guitars and basses providing screw adjustment of the length of the string. However for some reason they are not standard on acoustic instruments – maybe just because of the weight. Expensive ukuleles have fixed compensated saddles but cheaper ones (and mine is very cheap) don’t.

I checked the action (distance from string to fret) at the first fret and the 12th fret and these appeared to be ok – well within the figures given on the websites I found.

So what I needed to do was move the saddle away from the fretboard for the thickest (C) string. This involved cutting back the saddle until the intonation was correct at the 12th fret. Even on a cheap instrument this is a bit daunting.

To make the process reversible I bought a new saddle. I rubbed it on fine sandpaper until it was the right size to fit into the slot. The old saddle could be slid out once the strings were slackened.

Pineapple Ukulele Case

I’ve recently started playing the ukulele and am loving it. I bought myself a cheap pineapple Makala soprano uke on eBay – it isn’t the finest uke in the world but it does the job and I like the shape. One issue I quickly hit was where to store it – the cardboard box it came in doesn’t really do the job.

No-one sells non-bag cases for pineapple ukes. So I took a punt on a Stagg semi-rigid case on eBay. It didn’t fit but wasn’t too far off, so this post is about how I got it to fit.
