  1. Re: Not sure how to buy stuff that fits together.

    Yeah, was considering that, but was hoping to minimize bulk, weight, and expense by just getting a rigid one.
  2. Re: Not sure how to buy stuff that fits together.

    Thanks. I did post a couple of pictures on the first page, and the new design is simply to replace the lazy-suzan bearing that attaches those trucks to the dolly platform with a more robust bearing....
  3. Re: Not sure how to buy stuff that fits together.

    Thanks, guys. It's not pipe. It's steel tubing from onlinemetals.com. It is DOM:

    1" OD x 0.065" Wall Mild Steel A513 Type 5 DOM Tube - 12"

    If I had a lathe, it would be a lot easier to sand...
  4. Re: Not sure how to buy stuff that fits together.

    Thanks for digging up those pictures, guys!

    To join track lengths, I use short bars of 1" PVC pipe. They fit almost perfectly inside 1 1/4" pipe. I wrap a bit of packing tape around the middle...
  5. Re: Not sure how to buy stuff that fits together.

    Thanks guys. First, I'm using a tube because I have to cut it by hand! And a solid bar would be tremendous overkill. A 1/8"-walled steel tube is more than string enough, especially since the load...

    Thanks for the suggestions, guys. The freezer idea is, of course, sensible. But I'll wait on that until I'm done building the rest of what I'm making before trying it, since I don't think I'll get...
  7. Not sure how to buy stuff that fits together.

    Hi all.

    I'm not a mechanical engineer, but occasionally I need to build something.

    Currently I want to attach a wheel assembly (truck) to a piece of tubing that rotates in a pillow bearing, so...
  8. Need X-Y stage for drill press, or is this even a good solution?

    Hi all.

    I've been struggling to drill holes in straight lines on my cheapo benchtop drill press. I realize that runout is a huge part of the problem, but I think I can do a lot better by bolting...

    I just bought a square foot or two of acrylic scraps this morning. The place I bought it from sells it for about $4 a pound, if I remember correctly. That seems kinda high. I'd imagine you can...

    Nah

    Don't be too upset. Trying to make a purchase from them is a painful experience.

    Are you trying to make dolly track? I'd be interested in how it turns out.

    Hm. That link doesn't work. There's probably a bunch of characters missing where the "..." appears. Is there an official source of the R-2 plans?
