    And yes, I am into photography. Mostly landscape, some abstract/impressionism, snowflakes, and recently astrophotography with a small telescope, my DSLR and a tracking/goto equatorial mount.

    Thanks all for the ideas.
    I thought of ready rod but didn’t think it would provide fine enough control. However, as stated earlier I did find a canadian supplier of 3d printer parts and bought: an 8mm lead screw with a pitch of 1mm and a lead of 1mm. Super fine and definitely good enough. I also bought two 8mm linear bearings from them and a t-nut for the lead screw. Cost was $30 with $10 shipping. 1mm lead is plenty fine enough and the tolerance is far better than a home depot ready-rod.

    Today I bought 2 steel 8mm shafts from interior crafts so now I just need to figure out a way to build my camera carriage, the frame for the slide, a way of turning the lead screw, and a way of locking it firmly.

    One advantage of my work place is that I have an employer who has a couple CNC routers (albeit for wood) and a CNC Laser. One of these days we may hang out and see what we can come up with. I’m sure if anyone wanted to hang out on that day and participate in the build, he’d be happy to show you around his shop. I work for Lee’s Music, where Riversong Guitars was born. (not a huge group mind you, maybe 1 or 2 folks).

    I’m sure you know of the 3d printing parts company, but here is the link in case you don’t: https://spool3d.ca/

    And if you’re curious to hang out when I get the chance to try and assemble this, my e-mail is gregorybmurray@gmail.com

    Essentially yes. Those cheap ones though are a dime a dozen. Don’t positively lock when it is in the vertical position. They’re fine for horizontal work but the build quality just isn’t there. To get one that is of high quality costs anywhere between $250-700 U.S. Thought I could make one that locks well myself for the same amount as these cheap ones on Amazon, and if not, then I didn’t really lose much. Much better than spending a huge amount of money, I’d rather save it for my astrophotography.

    Hi folks,
    I don’t have much free time so I’m not sure I’d ever be able to make it in on Wednesday to check things out but my reason for joining the forum was to see if anyone could help me source some parts.
    I e-mailed Kile a while ago about finding a rack gear that was small enough and fine enough to use in a DIY macrophotography rail that I am trying to build. While it would be nice to know if there is a small scale manufacturer of these kinds of things -every rack gear I find online is for larger industrial applications, the smallest length being 2ft and usually only sold in bulk- I did manage to locate an 8mm lead screw with 1mm pitch and 1mm lead plus some other parts for $40 cdn.
    Not looking to motorize it, I need it light and portable, as the main reason I am using it is for snowflake photography.
    Currently I’m now searching for a handle to turn the lead screw and trying to think of a design for the carriage for the camera was well as a method of firmly locking the slide.
    Maybe one day I can get in on Wednesday to check things out.
    Thanks!
