Sherline 2000 CNC Mill

[cooliced]

Thanks for the link mate. gonna be ordering some bits from them soon.

So after posting in the single flute thread, i thought i would push my machine with a number of different endmills

with a 3 flute carbide 6mm endmill, i was pushing 1.5mm DOC at 350mm/min <- this i was very happy with

With a 2 flute HSS 6mm endmill (cheap, from ebay for 3 quid), i managed to get 3mm DOC at 225mm/min <- even more happier with this..

I cant wait to get the single flute carbide ones. hopefully go 3-4mm deep at 300mm/min would be the best thing ever..

Also im gonna start a dedicated youtube channel for my projects

Thanks for looking

Hi Mate

No problem, just make sure you pm me to point me at your youtube, interested to see how you get on! I'm black5f on YT as well, basically , a black 5 is a steam engine!

Make sure your endmills are capable of plunge cutting if thats what you need to do. Endmills will give a flat face, they have a flat end, but cannot always cut nicely in plunge and on hard materials and can skate a bit before they bite. One of the teeth needs to extend all the way across the centre, so they are not symetrical when looked at from the bottom. Slot drils will plunge and slot but don't give such a clean bottom to the slot. Most end mils plunge nicely but beacause they are flat, I find you get a neater finnish on blind slots if the plunge is taken a bit gentler. At the end of the day you just have to play with speeds and feeds till your happy with the finnish. Try some nickle silver, it's nice to cut, chips nicely and doesn't tarnish. Sounds like your having fun!

Or at the model railway club I'm a member of it was tea with no milk and 5 sugars!

Single flute cutters are good at plunging, but I still use ramping (spiral toolpaths) on the router. As long as the ramp angle isn't really steep it's much better.

I like that! Built a few, only got one left after regretably selling the rest and thats OO, brass scratch built.
But still have my black 8, O gauge, never got painted, weighs 8lbs, fully sprung.

If you browse abit, the Jinty is same construction technique but finished, still got a half built Scott somewhere.

Oh yes, even better! My very very old motion card wont do that, 2D circles at 1/2 meter a second,xy yz xz no problem, spirals have to be done in small xyz interpolated steps, RS232 = sloooowwww. Which is why I'm really interested in a cheap pid servo controller doing 480Mbits instead of 9600 baud.
