Building the C-Bot 3D printer: Part 4 : Cutting the linear rail

While I really wanted to use this printer build as an excuse to get a chop-saw (and I could have done this on my table saw), the offer of my buddy Mason to go to his house and borrow his sounded pretty good too:  While I’ve used quite a few tools in my life, I’ve never actually used a chop-saw, and it’s always nice to do something with someone who has experiencing doing it themselves.  Not that chop-saws are rocket-science.  But after using one, I think I’ll add one to my Christmas list…

For my build, I ordered nine meters (in one meter sections) of the 20x40mm, which would get cut into 14 separate pieces.  I would have needed more but Mason had an extra length of it, plus the 20x60mm I need.  +2 more cuts…

I hauled all my OpenBuilds v-slot linear rail over to Mason’s and spent the next few hours marking them, and cutting them up (along with the two Acme lead screws).  Could have gone a lot faster, but we were in no hurry, and time was spent staring at his C-bot and dreaming of the future :)

Overall it went very smoothly, nothing outstanding to note.  After I brought them home I spent a good amount of time with a dental pick (they’re awesome) and steel file de-burring all the cut ends, and cleaning them up.  Next up will be tapping the ends for the metric bolts (part 6).
