These are some jewellery boxes that I was making as Christmas presents. I has them cut out in time at least, but finishing had to wait till afterwards. The wood is pine and finished in 2-3 coats of Scandinavian Oil. One thing I found out the hard way is that you should pay attention to the fine print on the instructions, when it says to wipe off, you need to do just that otherwise it takes ages to dry.

The profiles were cut using 1/8in 2 flute end mills, using a feed rate of 1000 mm/min @ 12,000 rpm and 0.75mm DOC, while for the pockets I used a 18mm 2 flute router bit with a feed rate of 750mm/min @ 12,000 rpm and a 0.5mm DOC. I'm using the Inventables 300W spindle which I find pretty nice, but I want more power!!

One problem I ran into was chattering and a rough finish when cutting out the main body with a 30mm long 1/8 end mill (1000 mm/min feed rate & 0.75mm DOC) does any one have any recommendations for feeds and speeds for this situation?

cheers,
ijv

Do you have the link handy for where you bought the 18mm router bit? I've been using a 10mm end mill for roughing out things, and haven't yet seen larger stuff that's affordable, which will fit in my spindle. 18mm sounds like it would clear stuff fairly quickly. :)

There are "feeds and speeds" calculators around (including free), which might help: :)

Thanks, my daughters think they look nice as well, but that didn't stop them from decorating them with stickers and the like. :D

I'm in Australia, I got the bit at the local big box hardware store.

Thanks, that makes tonnes of sense. I should be able to find something locally or on Amazon along those lines. :)
