Align knee power feed - fitting the limit switch

The limit switch kit looks like this. The end stops slide on a piece of loominum channel mounted on the main machine body and the double-ended limit switch sits in the middle, mounted on the knee. The channel is actually chopped in 2 to make packaging easier, so you get to bolt them back together with the plate and screws provided.

There's a bizarre cast loominum bracket supplied (with 4 bolt holes in) that is clearly intended for mounting the switch but exactly how isn't at all obvious from the Chinglish (Taiwanglish?) manual supplied by Align with the kit.

The switch fits on the bracket but the shape of the bracket doesn't make for an obvious mounting method. Couldn't see any info on't net to help so just got with it myself in the end.

Hmm.

Bent this bracket back so that it was almost flat again. Seemed like a good start.

Something like this might work:

Chopped off part of the bracket in the bandsaw. Then drilled a couple of holes for M6 bolts, so I can then bolt it to the face of the knee casting:

Found one of these nasty US plugs in the legacy Canadian electricals box. These power feeds are 120V, so fitting a UK plug wouldn't be advisable. I need to move the table up and down but don't want to die of wanker's cramp, so it's a good time to connect up the power.

Need to get the switch end stops in the right place ie position the channel where it needs to be. Firstly, raise the knee until it's almost touching the quill nose:

It ends up like this:

Looks odd like this - won't be there very often.

Good chance for an "up skirt" photo, to see what the lift screw looks like.

After finding the upper and lower limits of movement, this is where the channel ended up. Knee at full height:

And lowest height:

Limit switch fitted and adjusted:

Job done!
