George's 8x4 router-me-bob

[JAZZCNC]

Here you go George have a look at these. This is one way and my prefered way to build them.
The Obviously the gantry is not showing but the Y axis rails could go either way like I have them or both on front or 1 on top 1 on front but this way I prefer because it brings Z axis closer to gantry, increases travel and is very strong. The belts help with resonance and allow gearing up or down if needed.
I use 16mm screws with 5mm pitch, sometime I use BK/BF bearing blocks some times FF/FK just depends on what I'm building and have even been knownt tomachine my own blocks but can't be arsed anymore as the chinese prices are so low it's not worth the trouble.

These are just reference models so not 100% accurate regards alignment etc but all materials and linear rails, motors etc are the correct and actual size and match whats available.

Hope this helps.
