New build with recycled parts on a ridiculous budget 120cm*60cm work area

That would no doubt help... maybe flip it around so you can still use your extrusion slots for mounting the rails (assuming that was your plan?).

Best option I think would probably be to use the steel as the mounting face and look into the self levelling epoxy method of getting a flat surface, but that may or may not fit in with your budget option. If not going that route, the question becomes which is the more precise mounting surface in terms of flatness - the steel or the aluminium.

It would be convenient to use the slots to mount the rails so maybe I should spin it round for now. I intend to upgrade or rebuild the machine what's most important is to get it working reasonable now and I will work out if it's better to start again or upgrade.

I really want 8*4 but I don't need it I actually need 4*2 (1/4 sheet) but I will get 1/3 sheet so happy with that.

Interesting with the self levelling epoxy will investigate but my supported rail and ballscrews on the bottom axis will be bolted into the extrusion directly.

Since I want to do aluminium would this be suitable

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.

Bit confused about what you are asking, what you linked to is literally just an inert container designed to hold oil and add it to a compressed air system to lubricate air tools.


You need a compressor, regulator (most compressors will have the regulator), an on/off switch (whether electronic solenoid or manual), and a nozzle. If you want mist, then really the best way to do it you will need two lines, one supplying coolant and one supplying air, ideally at different pressures (the coolant line only needs a very low pressure in my experience) and a mist coolant unit on the machine.

What you linked to wouldn't really be much use imo, the tank capacity is tiny - I use a 1 litre swimming pool filter container.

Yes I want mist! I will want to mill aluminium to the best quality I can do given the limitations of my machine. I will have the machine in an industrial unit which has a compressor airline point next to the machine which for my purposes can be considered always on with more capacity than I could ever need.

Do you have a pic of how you linked yours up?

I'm stalled until my mate at the scrap yard moves a printer (It's on top of a heap) for me so I can get the aluminium extrusion out AND 20-25mm twin hiwin style rail with carriages only short travel but I'm thinking for my Z axis.

The extrusion is T slot (Compatible with what I have now) It's 18cm*9cm (4 slots*2 slots) 6ft lengths which I'm going to use for mounting the supported rail and ballscrews on.

I'm going to cad it out in a minute but will make it a lot easier for me to build.

Actually as luck would have it I did recently post some pics here:

Lovely setup ;)

How thick are you mounting plates

Once I get the extrusion together and mount the SBR and ballscrews I need to make mine which I'm so not looking forward to lol.
