Albert, there is always a "box" around the linear bearings that pulls the bearings into the rail from all directions (at 45 degrees).

What bearing/restrainers are underneath the track to prevent this? (I may have missed this on previous photos)

I am also pleased to see that your welding is not that much better than my own...
On a sadder note you may or may not be aware of this:

Oh Harry - you are joking surely? Please say you are....
Oh I have a spare one I could give you if you were local but too expensive to send by mail I think.
Look, do your self a big favour - save up all your pennies - go off the grog - get another job - but get yourself one of these new fangled solar auto masks - I bought one for $60 and it is the best thing since sliced bread - it makes stick welding so much easier as you can see what you are doing when you strike. I got mine from Aldi but I am sure they are available at a similar price elsewhere like supercheap auto etc. Believe me you'll wonder why you never had one before.
PS Some say battery powered are quicker but I have never had a problem with mine and I have very sensitive eyes.
PPS I wonder if these things work with lasers?
