Hi there, this is my first post here. Hope i'm in the right section, but here goes!
I've just built this!...
(You may have to open these in a new window...)
6mm Aluminium base, 30mm thick HDPE blocks, bla bla bla... similar to the lumenlab micRos.
I want to use it to mill various things, but mainly, aluminium, acrylic, HDPE, and most importantly being an electronics student, PCBs!!!
The spindle you see is a old old old Dremel moto-flex I got off ebay for £30. It's a 110W motor fixed to 25,000 RPM. No good for cutting acrylic?
Thing is it's also very noisy and not variable. I'm a student and this sits in my bedroom screaming away, while my flat mates find it cool at the moment, I know it'll soon start getting on their nerves. I'm tempted to go for a Dremel Fortiflex, this any good? Nearly went and got a Kress 1050 FSE-1 but the achine won't support that weight too well.
In terms of some kind of coolant/lubricant for cutting aluminium, I've been using WD-40. Seems to work well but stinks out the room.
I cant use lots of liquid either because it'll end up all over the place, was thinking about using a water mist?
I need something similar to a Shopvac. living in the UK, I cant find any of those. Any small vacuum cleaner will do. Willing to try make one of those cyclone dust extractors.
So in summary, is anyone able to recommend:
A good spindle (not too heavy/noisy/under £250/variable speed)
A non messy, non toxic coolant/lubricant
A small quiet wet/dry workshop vaccume
Thanks all [=.
