Joe's 1000x600x200 steel and aluminium router started

VFD is working, quite surprised by this as it has been 'outside' for a couple of years. DDCS is controlling the spindle on/off and speed.

Today I cut the 20mm plate for the bed. The blank weighed 80kg which is too much to safely manoeuvre around the table saw so I just my very old and rough circular saw, lots of fluid, lots of smoke, but it did a pretty good job.


I took the edge off with a chamfer bit in a wood router, the bed sitting in place:


I took the a rough height map with a DTI clamped to the Z. As expected from bringing the rails into plane with laser and epoxy I have around 1-1.5mm total error (this was the frame error before pouring epoxy). The cross members of the frame are also not perfectly in plane and would require a little shimming under the bed.

I'd rather have the bed closer to planar that this, although the eventual spoil board skimming will fix it, so I'm contemplating attaching some shimming material to the cross members and surfacing this then bolting the bed plate down on top.

Another thought is to float the bed plate on some rubber washers and compress them until the DTI reads zero everywhere.
