Since I want to do aluminium would this be suitable
http://www.ebay.co.uk/itm/1-2-Inch-A...0AAOSwzqFZAIzb
paired with a compressed air solenoid to clear the chips?
Was having issues getting my motor shaft to align with my ballscrew I'm around 0.5mm out. My friend checked my couplings out and they're flexible couplings but still going to try and get the motor shaft aligned. but they do seem to work fine.Last edited by Desertboy; 26-05-2017 at 07:01 AM.

The right tap makes all the difference! Broke my m6 spiral machine tap a while back and had to tap 7 holes with a straight old regular one last night. Probably took 3-5 minutes / hole because of all the back and forward you have to do. :(

Managed to do 10 bolts without a Tap but hard hard work take note the size of lever lol. Ran out of bolts now when the rest come the tap will be here as well.
2 pieces making the bottom frame are 6045 extrusion which makes it look a little odd. I wonder if I spaced them close enough together the gap is less than 30cm between each extrusion will have an 18mm MDF board on top
I'm impressed with KJN's cuts the frame fits together perfectly. I had the outer frame cut from 9045 ages ago then had them cut the 4545 and 6045 that make the bed up the other day. Other places I;ve used they would not fit properly.
Need to have a think about legs I want to have a shelf underneath so I can put vacuum cleaner & cyclone, water cooling, etc on the shelf to keep things neat and under control.Last edited by Desertboy; 05-08-2017 at 02:39 PM.

Hmm this might have been talked about already.. but is the gantry spanning the long axis instead of the shortest possible?
Or is the image playing tricks on me? ;)

There was method to my madness, I originally had SBR25 and 15mm clone Hiwin's so I decided the SBR25 could take the most weight and made my gantry span the longest axis. (This is 1.5m) then I ordered 1 1.4m ballscrew and 2 1m ballscrews. A few weeks later I managed to score more original 15mm Hiwin's so now the whole thing will be linear rail.
If I had the Hiwin's originally I would have built it the other (More conventional) way round but hey hoe.
If this is a real issue with flex I will have to buy another 1.4m ballscrew and convert it over it wouldn't be too hard.http://www.mycncuk.com/threads/10880...60cm-work-area My first CNC build WIP 120cm*80cm

When building like a mechanical pirate the plans can always change :D
