Ukulele Making Course.

This is where we don't want anything but evidence of your finest wood butchering in all its glorious, and photograph laden glory. Bring your finished products or WIP's, we love them all, so long as there's pictures, and plenty of 'em!

Whilst I have no interest in making a ukelele, the methods used in this build are fascinating, and I can certainly appreciate the end result. Great work, and a really interesting thread.

As someone who has snapped off plenty of 6mm router bits in his time, how do you apply a sideways load to a 0.6mm milling bit without instantly breaking it? :eusa-think:

feed and cutting rate. :)
small cuts, high spindle speed (cut rate), low feed (movement) rate. it's all about balancing these three.

Thanks, Roger.

Firstly you ensure that you program the cutter to ramp gently into the material at probably 24000 rpm, and MoP is hard stuff. Then you only cut to a depth less that the diameter of the cutter. That way, you might not end up breaking any! :) But then, you might.

A trick I was given by one of the Crimson Guitar guys, when using 0.6mm cutters, carefully break the flute to half its length. They still cut and are a lot stiffer and less likely to snap in use. It does work, when cutting the bog oak for Mike I needed to use a 0.6mm cutter to get the fine detail.

Malc,

Do you have a link for those cutters? All of the ones I have are much longer flutes, hence the need to snap them!

Dave,

The ones you want are BB 2F-BB2055.

You need to select the middle box in the picture, outlined in red.

Then choose the diameter and the length of flute.
