i knew this would happen. i wanted to keep this cheap but i have been looking marchant dice online store and i see lots of stuff i like at reasonable prices

they do hardened high carbon round rail

from reading other threads i think i need 16mm for the bed. they have this...w16 (h6) at £1.90 per 100mm. now i assume that product is 16mm diameter, not sure what the h6 means though.

also have these http://www.worldofcnc.com/products.asp?recnumber=17
at £5.40 for the LME16UU i assume that is to suit a 16mm rail.

they do rail supports as well not too dear.

now, i am only guessing when i browse all this stuff. all the stuff looks really nice but i am not really certain what to get. i have guessed the above two products and eyeballed a few others, left to my own devices i would probably go with these. am i right in thinking that i can get away with thinner rails in the gantry?

i am now considering putting off the purchase of the controller/steppers untill maybe february so i can spend some money on these. does anyone know if these guys accept paypal.

this is all your fault by the way:heehee:
this is turning out the same as my main hobby, nitro rc racing. i keep getting tempted by nice shiny new stuff and spending a fortune on it, the rc car i currently drive is worth over €1000

for anyone interested
