3 Axis 900x500mm

[Wal]

Got a couple of jobs done in the last couple of days. Finished the e-chain that runs beneath the bed and is attached to the X-axis - a brief and rather lacklustre vid here:



The fixed end that travels uses a similar spacer as the one I made earlier in the thread - that way the chain stays horizontally level. There's an additional support bracket halfway up the bed, I had to nibble a bit of it away as it fouled the ball-nut housing:



Another thing I thought I'd have a look at is creating a mechanical union between the router and the bench that it's sat on - I was going to screw some strategically placed blocks down to prevent it from walking but thought that I might as well add some mass to the unit as a whole and leverage the weight of the bench (and all the stuff that'll eventually get stored down below) to help hold the router down.

I took the feet off and drilled/tapped a couple of M8 holes in the middle 'foot' - too late to use the corner 'feet' - lack of space notwithstanding, I'm not strong enough to lift the router off by myself - I could have attempted a bit of a balancing act, but laying out on the steel L-section would have been, at best, a very awkward affair...



Next I drilled a couple of 8.1mm clearance holes for the bolts:



And then bolted the router bed down to the bench sub-frame.



There will eventually be a third plank running up the middle of the bench - I'm leaving it out for now so as to be able to get access to the underside when needed.

Waiting for CY cable and switches to arrive now...
