DIY Linear Bearings

[JAZZCNC]

Also, if you're following that design..... don't... the single central screw for the X-axis will cause you hours of pain if you plan to cut anything stronger than cheese at the full width of the Y axis.

While I agree completely 2 screws are best route in this case it's marginal Irving has he only wants 600mm cutting width, if he has wide enough bearing spacing on X axis and builds ridged Gantry it will be fine for upto light Aluminium work. On a budget this will work fine and with bit of thoughtful design could easily be incorporated later if needed.!!. . . . .Carry on Sir I say.

Are we talking 50mm x 3mm mild steel box?

I'll call my local metal supplier tomorrow to get a quote for the steel box & then start drawing something up.

Yep 50 x 3mm and the last time I bought some which was 2-3months ago it cost me £26 for 7.5mtr length. That's was plus vat but if like my friendly supplier they will some times do without Vat.
