Re-Building Suregrave CNC

[PeterC]

Hello All,

Made good progress today. I built an additional bench to hold the CNC. I had to cut into my outfeed table / workbench but I think it's turned out well. When not in use I can fit a board over part of the CNC so I can use the table saw outfeed, I simply have to lift the board out to expose the whole CNC.



Looking at the strength of the X axis. I agree that the axis looks weak, there is nothing support the linear rail against any deflection. I have had an idea to strengthen it up. I'm going to get a length of 28mm square steel tube. My plan will be to bolt this to the back of the linear rail and tie it back into the gantry supports (which are ironically very well built). I'll have to cut a little bit of the thin black plate away t(but this is just cosmetic) to allow the tube and linear rail to bolt into the supports. In one of the attached photos I'm holding a piece of section to give you an idea. Would like to know what you think?

I didn't get time to look at the spindle, that's for another day!

Thoughts, comments or suggestions always welcome!
