The new Limit switch in service. Ill get the model # But in a nut shell its a magnetic reed switch. Normally open. N.O.

This is the Y axis Minimum limit switch Mounted pretty much where the old switch was mounted. I used some Aluminum 1/2 u channel as a mounting plate.

DIY Laser beam alignment tool This is just a piece of aluminum I turned on my lathe.  On one end fits snuggly into the end of the Co2 laser. Off ebay or similar I installed el-cheapo laser pointer down the middle and used 3 set screws to align it so its truly centered.I then drilled 3 holes so I could choose which ones the wires would pass thru. Works perfectly.

The red paint is to lock/hold the lens alignment of the laser pointer itself.

Laser50W-1015 Laser50W-1016 Laser50W-1017 Laser50W-1018 Laser50W-1019

I have begun the clean up of the inside of the tube. I flushed CLR thru it for 2 days straight. and wow did it get clean…

Laser50W-1020 Laser50W-1021 Laser50W-1022 Laser50W-1023 Laser50W-1024

Apparently the corrosion was so bad the water inlets were hanging by a thread. and pretty much fell off in my hands after the cleaning. Fortunatly for me I was able to machine up some new ones and quickly epoxied them back into place. now all I have to do is hope they dont leak!
