Well....I have the biggest part done and all looks great to me. I have saved the design for my Z-Axis and the A-Axis until I had the main framework done so I can have a better perspective of how to proceed.
My main question here is does it make any difference strength and rigidity-wise which way I mount my Z-Axis linear bearing blocks? By "which way", I mean, bolted to the X-Axis blocks or moving on the Z while the shafting is rigid? (ex. attached)
The design is for 6" of Z and the brg blocks are 6" long. I would like to have full engagement of shafting in the bearings when extended to the max. Originally, I had it so the blocks were rigid on the X and my Z shafting moved. I felt having the extra bulk of material behind the spindle plate would be more rigid at extension giving me less vibration on the tool.
(the red machine, I was trying to show what material I have already and will use in some configuration...red-I have)
Any other criteria in the Z-design I need to watch out for?
Thanks for any consideration......
