Ger 21,
I thought about welding 2 pieces of angle iron together and then set the pipe on top and tack weld the pipe to the angle iron for support the problem I have is bearings how do I build the bearing races to ride on the pipe I need to have support of the bearings in the x,y,and z directions correct they cant just ride on top and both sides cause then the gantry could lift as you lower the z axis correct I thought about the jgro type bearings but with the supported tube as I mentioned but is the jgro bearing any good or is there a better DIY way? |
