Totaly new to this so pass a few ideas by you lot and see If they are good or crap!
Building a fairly big CNC for wood working so need a large bed size
In a perfect world 10ft x 5ft I do have the space in the workshop for that
BUT a bit over optimistic for my first attempt LOL so 5ft long x 3ft wide
With hopefully 2ftx4ft working area for MK1
The bed or base will be kitchen cabinates with a strong top as I am a cabinate maker
and so thats very easy for me to make
But the linear slides ,,, HUMM
Seen the skate berings and ali angle thing ,, works but
The V grove berings are better but at more than £12 each !!
Proper suported rails ECT is out of the question at the lenths I need
SO been brain storming and come up with ....
An aluminum I section thats 54mm x 25mm that has a 6mm hi x 4mm wide rib on the 25mm face running right along the lenth
I could use the skate berings in a V on ali angle , but its ugg ugg
I could use V berings but at £12 quid each and hardened steel on ali
would not last very long !
So skate berings with tyers? , replaceable nylon tyers
Ant thoughts or sugestions
thanxs
