welding steel base or just getting aluminium extrusion

[reefy86]

well after watching a lot of youtube video's i am starting to come up with a method and feel a little better however after getting the materials and all necessary equipment/tools then its still going to cost me £1k+ anyway but i suppose i learn a new skill trade in the process.

You forgot diagonals when looking in the plan view, see here what I mean; http://www.mycncuk.com/threads/6565-...2425#post52425

if only you could get the steel this clean lol, anyways i know i did this all before but ive done a few tweaks but i am a little concerned with the gantry side plates being so wide and because the aluminium gantry beam is pushed to the back it leaves a large space on the flange plates. this is because i was reading about not having the z axis over hanging and to have the gantry side plates in front of the z axis.

I have gone with 100x100x5mm all round for the frame
all plates are 20mm thick aluminium
linear rails 25mm
ballscrews r2010 driven on both sides with nema 23's 4nm and a rotating ball nut due to long 3000mm ballscrews

still thinking for the rest but whats your thoughts?

is £400 the going rate for 3 meter ballscrews r2010?

noob question here with it being the first time tapping a hole my self if the linear rails holes are 4.5mm what would the tap size be to the aluminium plate its attaching to?
