Do not hurry now,try to get a bigger one,a bit with a cutting surface about 20 or more mm will save you much working time from the machine an d a better result.
Hmm dont think my spindle can handle 4500rpm. Standard Chinese 2.2kw thingy.. Will try 6000rpm ;)Quote:

Will try to get better material than ply for my "real" spoilboard :)

I bought a 12.7mm 2 flute trend straight router cutter for wood and found it has a far better finish than the 2 flute carbide endmills I bought from China. The 2 flute carbide endmills leave an excellent finish with aluminium.Quote:

I think mdf is cheaper here, depending on the quality of the ply. Marine ply and birchply is insanely expensive :)Quote:

When I feel somewhat secure, safe and possibly tipsy I will bring out the oak :D
Want to find a local supplier of varieties of endmills. The only thing the stores here sell are for handrouters. Oftentimes with bearings :(
A nice singleflute for acrylic would be nice.
Aswell as some downcuts for soft wood!

Ok, yes it will certainly not go that low - i have the same spindle and its useless below 8000, this is the issue with HSS - it needs low speeds or it burns up. Try and find a wood router bit - usually carbide tipped etc.Quote:

If you can find a bit at a good price with bearing at the end,take it remove the bearing and trim the insert point flat with a Dremel or a similar tool....
How are folks using these spindles for Aluminum (or are they)? I would think that even with solid carbide 3-flute endmills, 8K would too fast.Quote:

Single flute work well as they are pretty strong and have a lot of chip-space in the flute.
When you get down to sub 1mm tools you need mega-rpm.
Don't forget these motors are sold as engraving spindles - the tools are sharp pointed and can take any rpm you have.
