The table can't be made worse. It needs replaced anyway, but if you can find a person who can weld it without warping the alignment of the guides, it would save a bunch of money. Some cast aluminum alloys just don't take well to being welded. They either resist having the weld metal stick, melt too easily, or after bring welded will shrink. What might work is Muggyweld. There are many videos on youtube showing various repairs with it.

It cracked about 2ft in from the front left corner and runs about half way across the table in the 5ft direction. The table is supported from below by 10 linear guide blocks on two rails. The crack runs across between the 1st and 2nd set of blocks, about 4inches from the 2nd block. Is there any hope of repairing the table? Are we going to have to replace the whole table? Could the crack be welded, or is that a bad idea? My main fear is that warpage issues will cause the linear guides to bind. (The table surface can always be re-milled flat.) The crack isn't gaping or misaligned, and the table doesn't "look" warped now that It's cool _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
