Unsupported Precision Round Rail Calculator

[Ross77]

You're right. I just stuck the x4 in somewhere convenient

No problem with that. Thats what its all about re-engineeering equations to suit the problem in hand but it is goood practice to state any changes and the reasoning behind them. stops people like me asking questions

I'm sure all this could be resolved with a good fashion conversation. pm me your no. or maybe we will have to try the skype option....?

I tried opening it, but my Excel won't open it for some reason
Could someone do me a quick calculation
I am upgrading my Homebuilt Plasma by extending the table, this is the design so far
The Y Axis has two unsupported solid rails @1500mm long (See Picture) the centre bar is the Ballscrew.
I still need to add some form of aluminium extrusion to stiffen up the Y Axis Gantry.
It has the Z Axis assembly hanging off of it and also the Plasma torch, not sure what that will weigh.......
I think I might need to put some form of support under the rail, I had to do that on my first machine, I had small angles welded at 45° under the rails, and setscrews to bear onto the rail

Thanks in advance
