I've said this a thousand times... this stuff is tough...there is NO flex at all in the track (1000mm).
Yup -- I just read the whole thread top to bottom, so I saw the photo several times (In the very pink setting) , and I'm pretty sure I could calibrate the bearings in my sleep now, even though I've never seen them in person. I have my forum preferences set to 40 posts per page, so it's /only/ a 17 page thread for me.
That sounds great then. I'm bummed that I've lost my excuse to buy a monopod, but with the $$ saved on the DIY I just might be able to justify giving the Zazaslider it's own bowl, or something along those lines. Stay tuned...
(oh look at that, the glidetrack ad is at the top of this page. How ironic...unless we're talking gmail of course, then you're upset if the ads you see are unrelated to what you're talking about)
