My baby 15" x 15" machine

[wilfy]

ok i "think" i've finished designing the z? axis i've included a picture with 2 views, what i'm looking for is constructive ideas, so far everything is steel i think although some of the plated bits might end up being aluminium i would rather weld everything than tapping steel/alu.

the small rectangle box sections are 50mm x 25mm and there is acctually only 2 pieces of 50mm square in there but these could also end up being 2 pieces of 50x25 slapped together depending on cost. the plates are all 10mm steel although the mount for the BK bearing is drawn at 5mm i'll edit that later.

this has 100mm travel which i am hoping will be enough it is a 15" x 15" machine afterall so is intended to be small work pieces.

so questions to anyone who can help before i progress further. does it all look like it will function.. i.e have i connected all the right parts in the right ways? a simple question to ask but i did originally put the ballscrew blocks on the same side as the rails.

secondly as i am intending to make this out of steel is there going to be alot/too much weight on a 16mm screw and rails on either y or z axis?

i can provide sizes of everything so far and if someone can tell me the weight of a piece of 50 x 25 steel box section i could work out the weight of everything.



also if you would like a better view of anything let me know
